Vista question (dual core support)

Question: Vista question (dual core support)

I am currently running windows xp, and linux suse as my Operating Systems. XP is 32 bit and Suse is 64 bit. I was wondering if I installed windows vista ultimate 64 bit edition, does it take more advantage of dual core processors? My cpu is an Athlon 3800+ X2 (dual core). Basically will the 64 bit edition make a difference. Any feedback would be appreciated.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

is anyone running this app w/ dual dual cores? my two single cores are maxed out and i'm now considering an upgrade to (2) 2.0ghz dual cores...

does anyone have any suggestions for any software comparable to pinnacle studio 9 (that's really cheap)? my primary use is choppin up MPEG clips.

I'm buying a new computer with Vista home premium (32 bit), and I can't decide whether I should get a 2.4 quad core or a faster dual core (since it's cheaper).

I've searched about this but all the results I've got were from 2007, so I'm not sure if things changed much now.

So what do you think? will I benefit from the additional cores? or shall I go with faster dual cores?
appreciate your help

Ok, I searched & didn't find it.

Can someone help me clarify this:

I thought the dual core systems were going to be ok with XP Home, since Microsoft said its only going to count packages. (IE: HT or dual core will be ok with XP Home - only count as 1 package)

And Pro would be good up to a dual-processor system with dual-core. (2 packages = 4 cpu's)

And what about the 840EE. Its only one package, so can it run on XP Home also, even though it supports 4 threads ? (1 package = 4 virtual CPU's)

Answer:Dual-core support for Windows XP

Basically DC and HT don't count for the dual proc limit as far as I know. Only 2 seperate physical processors.

I have a GA-8I915PMD motherboard (the only part of my PC, along with my processor (a P4 3 Ghz) that I have not upgraded since I got it), it has an LGA775 socket.

Will this motherboard support an Intel Core 2 processor? They use the same socket, but the packard bell web site only say's it supports up to P4 with HT. Or is the bios to old to understand the new processor, as the latest bios update was Febuary 2006.

Answer:Solved: Dual core support?

Your machine doesn't support dual core processors. BIOS is just one part of the equation. Your board has a 915P chipset, and the 915 chipsets did not support dual core.

Hey guys,

I need to enable my dual core AMD X2 5200+

Originally I had a single core, but I have moved on to greater things lol

I need to be able to do this without reinstalling the OS.

Just as a heads up, if you find that thing from or .com or something, don't link it plz, cause I tried it 3 times, and it left XP in a non-boot-able state and I had to run Ubuntu to undo everything. Or maybe I or the instructions are wrong, and they actually do work. Either way, help will be greatly appreciated.

Answer:Can the Intel Pentium Dual-Core CPU 6300 Support ten?

Don't know why not. The base specs. require a 1GHz CPU and 1GB RAM for the 32-bit version and the specs. call for a 1GHz CPU and 2GB RAM for the 64-bit version to Upgrade over Windows 7 w/SP1 or Win8. The only issue I can see is if Win10 will support all the resources on the motherboard.

According to a table at Wikipedia it says that the maximum supported CPU Core's for Windows 7 Home Premium Edition is 1. Does this mean the OS itself will not support a dual core in its own operation, or does it mean that it will nullify any Dual Core support on the system thus rendering a Dual Core useless?It seems that only supporting a single core is rather stupid considering I bought my computer 3 years ago, I don't see why they would even release an OS that doesn't support hardware 3 years old, especially considering there are now QUAD-Core machines.

Answer:Will Home Premium support a Pentium D Dual Core?

Replying to my own thread:

Upon further reading the chart states "Number of Physical CPU's" and not "Number of Cores" so any version of Windows will run even a Quad-Core as long as they are on ONE single chip.

I am torn between buying one of two Acer laptops. Both have almost identical features--RAM, HD, webcam, 6-cell battery, memory card reader, and are the same price--$499.00 (on sale); but the processors seem to be the big difference, and I would like to know which one you folks feel I should go with.

I should also mention that the AMD laptop also has a Blue-Ray Disc drive (and read/writes normal CDs and DVDs).

The only other major difference when comparing specs is that the AMD laptop has an HD CineCrystal LED-backlit TFT widescreen display, ATI Radeon HD 4250 graphics with 256MB of dedicated system memory, supporting Unified Video Decoder 2 (UVD2), OpenEXR High Dynamic-Range (HDR) technology, Shader Model 4.0, Microsoft DirectX 10.1
.........While the Pentium laptop has CineCrystal LED-backlit display, Intel HD graphics with 128 MB of dedicated system memory, supporting Microsoft DirectX 10.

I've been driving myself crazy for the past 3 days trying to decide which one to go with and I need to decide quickly as I'm not sure how long they will be at this sale price--and I do have to stay at the $500.00 range. From the many laptops I checked out, these 2 seem to offer the most for the money. I would truly appreciate your advice!


Answer:AMD Turion X2 dual-core P520 2.3 GHz or Intel Pentium Dual-Core P6100 2.0 GHz?


I'm sorry to bother you folks again, but I noticed that my question had 55 views but no replies. Did I perhaps give incorrect or confusing information, or maybe posted my question in the wrong forum? I tried looking at some of the other similar questions asked, but none seemed to help with my question.

I guess I'm basically wondering that since the 2 Acer laptops are the same price, would you go with the Intel Pentium Dual-Core P6100, 2.0GHz, 3MB L3 cache, or the AMD Turion X2 dual-core P520, 2.3 GHz, 1066MHz Front Side Bus, 2MB L2 cache. This laptop also has a Blu-Ray Disc Drive, but I've read conflicting opinions on whether having this is necessary or not.

Although I consider myself to be an intermediate computer user, I am lost when it comes to processors, and also when it comes to 'dedicated amount of system memory.' I know that 'dedicated' memory is better, but does it make a difference how much there is in different brands? In other words, could the lesser amount of 128MB 'dedicated' in the Pentium still be better than the 256MB in the AMD? I'm leaning toward the AMD Turion laptop because of the higher numbers, but I've read enough to know that you can't always rely on that alone.

I'm sorry to ask my question again, but I've been given a lot of help here at CNET in the past, so I was surprised when I logged on today to see that no one expressed an opinion on which one of the two the... Read more

No the dual core processors would run at there stock speed 3.4ghz but you have 2. The advantage of this is that one of the cores can be working on say encoding a dvd and the other could be dealing with system tasks.I would say that you would be better off with a dual core chip.

That is the older core and yes they do tend to run warm. If you want to go dual core, I would go with either the new core2 duo or if you want a bargain then the Pentium D with the pressler core ie the 9xx series. These run cooler than the older 8xx series. This is due to having EIST tech. I run a 940 and right now it is at 32C; not bad at all.

I will be getting a new PC late this year. The only demanding Application I use is Photoshop 7. I cannot afford to upgrade to CS which is probably coded for dual core. Suppose I get a dual core PC running at 2.4 GHz. Will PS 7 run slower than on my current 2.8 Ghz machine ?

Answer:dual core PC question

Hard to say. Even though applications aren't coded for dual-core, any multi-thread application will usually benefit from the dual-core processing power.

I would suggest that you consider waiting until you have the money to make a larger upgrade, since you may be disappointed in the amount of improvement. Also, you'll want to make sure your BIOS and chipset drivers will properly support the dual-core CPU, I'm still smarting from buying a MB that was "supposed" to support dual-core, but didn't!

Why is it that when I'm running a process (like extracting files in winrar), my CPU is only running at 14% (both cores). Why can't it go faster to make the extraction quicker?? I don't understand why both cores have to bottleneck at 14% or so. Why doesn't it work at a 50% load or something?? There is nothing else going on (just the extraction). Any input would be appreciated. Thanks

Answer:Dual Core CPU question

There's only so much resources that a program can use up and it seems the Winrar is extracting as fast as it can. It's not an issue with your CPU, just an issue with the Winrar client in general only being able to extract at a certain pace - as far as i'm aware there's nothing you can do about it, only wait for the extraction process to complete.

Even if it's a Quad Core, it would extract at the same speed.

Hey there,

Despite all info out there stating a 2-core processor would be much faster that a single core CPU, I am still undecided if I should upgrade my pc now or wait a little longer.

My actual system has a Prescott P4 3.4Ghz/1MB/800Mhz with HT and 2-1GB DDR Kingston 400Mhz modules runing on dual channel (to match CPU bus), and the main applications I use are Adobe Photoshop and Adobe Illustrator. Also, this mobo allows me to add 2 more 1GB modules of ram (up to 4GB in dual channel)

I know HT enabled would help when runing Photoshop and surfing the web at the same time, but not when runing Photoshop & Illustrator on sepatated monitor since HT is not 2 physical cores, so my question is:

Considering I am quite short in cash, which Dual2Core processor would be the minimum to look for to match & increase the performace of my actual system, considering the new mobo would only accept 2-1GB of DDR2 667Mhz (1333 Mhz in dual channel)

Answer:P4 HT vs Dual 2 Core question

It seems I am really confused regarding Dual Channel then. I was told 2 modules of 512MB at 400Mhz (installed on the right slots) teorically would have the same performance than 1 module of 1Gb at 800Mhz, so it is not true?

I have a mid-tower HP business d530 system, which in case of upgrading would mean new chassis too. The full specs are these:

Ok, so I was an an idiot and always thought that i7 meant quad core and was better than i5. However I just realized that there are some laptops with i5 that are quad core. On the other hand, this i7 Y2P laptop (which I won't get to play with till the 21st, since I am out of the country) has a dual core. I now have a lenovo z570 quad-core i7 (note to Lenovo: still upset Lenovo about our power management software that never got fixed after 2 years). How much of a speed decrease am I expected to see??? I am going from quad core to dual core, 16 gb ram to 8 gb, 1 TB HDD (256 SSD + 750 HDD) to only 256 SSD.... Feels like I am compromising a lot for a touch screen.  Should I return the laptop? Legit this whole i7 and i5 is crap marketing to get more $ imo. At the end of the day, I prefer quad-core i5 over dual core i7. What is the difference?  Looking at it, I see only a 0.4 GHz between the i5 and i7 model, both being dual core with hyperthreading. In the end, i7 is like $300 more. Why? Feel like I overspent on this laptop cuz of a marketing gimmick. 

Answer:Question about the Y2P Dual Core processor

The only processors available in the Y2P currently are a quad-core i7 and a dual-core i5 (plus the i3 but we'll ignore that option). If you want quad core then you must get the i7. I have the i5 and love it, and honestly I would not worry too much about it. The i5 supports hyperthreading, so it shows as four CPUs to the OS (the i7 would show as 8). Both the i5 and i7 are rated for the same Total Dissipated Power budget of 15 watts, which means that even if you can get all the cores of the i7 going, it can't use any more power than the i5 does so honestly I'm not sure how much faster it would be in real-world stuff because it's generally going to be power-limited. And many applicaitons still won't use more than one or two cores so you would not see much of a difference in a lot of cases. The i7 will be faster than the i5, but probably not as much as you might hope, and it probably won't make a significant difference as both of then are low-power Ultrabook chips designed for low power dissipation for good battery life, and have significantly less performance than their higher powered desktop equivalents. I'm really happy with my i5 performance, both for everyday web browsing as well as gaming. Z.

AMD Athlon Dual-Core QL-67 (2.2GHz, HyperTransport? 3: up to 4.0 (GT/sec), 2MB L2 Cache)

Intel® Pentium® processor T4300 (2.1GHz, 800MHz FSB, 1MB L2 Cache)
thank you

Answer:Comparing amd athlon dual core and intel pentium dual core

They are quite similar. Both have nearly the same clock speed. Both have a total of 1MB of L2cache but the intel's is shared and the AMD's is exclusive. The intel is 45nm and the AMD is 65nm which means the AMD will run hotter most likely. The AMD gets a boost from its on die memory controller and HyperTransport links on its motherboard. Both are capable of running full 64 operating systems.

The best difference between them would be as to what is on board their respective laptop. The AMD will have quite respectable performance from its video chip as I would hope it either a Radeon HD 3200 or better a 4200 with SidePort memory. These are about the best you can get for integrated video these days. The intel will undoubtedly have a GMA4500. These don't game very well nor do they do a very good job of playing high def video. The AMD chipset should have a fairly complete selection of connectors and functions. The interl may or may not, depending on the maker.

Both chips have a TDP of 35 Watts. The intel should offer slightly longer battery life for a given series of tasks, say about a half hour.

As you can see, these two CPUs are quite similar on and of themselves, the supporting cast of laptop parts makes or breaks the deal.

Needless to say that a CPU upgrade in a notebook is totally sensless because you won?t gain real big performance. On the other side you have to be a technician which should be familiar with such systems, because a mobile system is NOT THE SAME like a desktop system.

This system is not able to take a dual-core cpu because you just have a Intel 910/915GM chipset which can just take Intel pentium M.

I am looking into getting a new wireless router for home and I see now that they come with Dual Core CPUs and GHz CPU speed. Will either of these have a 'real world' benefit over my existing router (Netgear WNDR3700v4). Specifically I am looking at the Netgear Nighthawk.

Thank you and Happy New year!!

Answer:New Router question: Dual core or faster MHz CPU

Unless you flashed the router and did a lot of fancy stuff (which I'm not sure if the Nighthawk comes built-in with those kinds of features) then probably not. Consumer routers used to suck for a long time having inadequate hardware and more recently they've decided to bump up the specs and more or less has become a selling point.

It does make you think twice because some of the specs are getting so damn good they're beating out low-end SMB gear, but alas it really depends on the software as to whether it can take full advantage of the device in the networking sense.

If I have a Core2 Intel processor running at 2.4 Ghz does that mean the processor is running at 4.8 Ghz because each core is running at 2.4 Ghz. Does the same apply to a quad core processor as well.


Answer:Question regarding dual and quad core processors.

It does not, it just means you have two cores of 2.4ghz each..

Same applies for Quads or any other multi-core

Can somebody explain what I'm getting by upgrading from an Intel CPU 2.53 Ghz. to an Intel dualcore 2.33Ghz CPU?
Does it mean that being a dualcore it will run at twice the clock speed i.e. in this case 2.33Ghz x2 = 4.66Ghz?

thanks for your time.

Answer:Dual core question, whos the expert?

No, in layman's terms, its more akin to two CPUs running at the same time, being able to share the load. Both run at the same speed. However, it requires an OS that can take advantage of it, and applications that can take advantage of it.

Most games do not. Many applications do not. Windows XP and Vista do, allegedly Vista moreso. Many encoding apps do too.

DVD shrink is multi core/cpu aware, and the performance increase is tremendous, for example.

Hey guys,

General question. I have two options for laptops, one with a AMD64 MK-38 processor, or an Intel Dual Core CPU, which one should I go with? To get a better picture;

AMD 64 MK-38 notebook

Intel Dual Core notebook

This AMD laptop has Vista Basic, while the Intel laptop has Vista Premium. I'm thinking that the Intel laptop is better, but I could use some second opinions.


Answer:Laptop CPU question; AMD 64 MK-38 or Intel Dual Core?

They are pretty much the same. If you really want premium, go with it.

I have a Lenovo N500 (Pentium duel core T3400 2.16, 3GB) Vista and my hard disk has failed (After 18 months!!!!). The only recovery disks I have are XP Recovery/Downgrade. I have put a new hard drive in and used the XP recovery disk, after the install XP boots for the first time and runs through the Lenovo post XP install, then on re-boot XP hangs during start-up. The only way I can get XP to start normally is to boot to safe mode and disable one of the cores using MSConfig.Given that it boots to safe mode with both cores enabled I figure that this is some problem with drivers/software. If I use SOS boot to try to get more info I get to the screen that list the processors memory etc and then it freezes, so not much help. The laptop is up to date with all the drivers from Lenovo, and windows update. This happens with XP service pack 2 (This is what is installed from the recovery disk) and with SP3. Have spent too long getting nowhere talking to Lenovo customer support in India, it looks like it will cost £45 to get a Vista disk sent to me! If I can't get XP to work properly, does anybody know if you can use any Vista install media, or does it have to be a Lenovo Vista disk to work with the product key with the laptop? Any help greatly appreciated Thanks in advance

If you can find a OEM disk the COA on the bottom shouldwork with phone activation. Any company, Dell, Gateway, etc.just insert your key when activating. Also the "Anytime Upgrade"disk for Vista, if you can find one.It may not work with a retail disk, I am not sure.

No, you don't have to have 64-bit, yes you can use your 32-bit disc.

I've got a Asrock Am2NF3 VSTA board and a HIS Radeon HD 4650 card that I wanted to build a rig around, but I read that Nvidia removed anything mentioning Nf3 support with an ATI AGP card and Dual core CPU right before vista was released. So i'm guessing this was never resolved in Windows 7? I doubt they made a update for such an old chipset.

Today I received the Intel Core Duo T2400 processor which I ordered, to replace the Intel Celeron M 430 processor in my laptop (the one in my sig).

After replacing it successfully, I boot up the laptop, only to find that the system freezes right after POST, and fails to boot into Vista. So I take the keyboard off, and pry out the CMOS battery, left it for two minutes, placed it back in and booted the laptop up again, but still to no avail.

I went into the BIOS settings (HP customized) and it's detecting the processor correctly. All the BIOS settings were correct. Also, after installing the dual core CPU, a new option appeared allowing me to enable or disable 'Dual Core CPU' functionality. This however, was enabled .

I thought I'd try changing some BIOS settings, the first was to disable 'Dual Core CPU' functionality. After doing this, Vista booted successfully! A sigh of relief? Kind of, but not really, because I've purchased a dual core CPU and only getting half of what it's worth.

What to do...?

I don't have a specific problem with Windows XP or Vista, but I have a question about the difference between how they direct the function of dual-core processors. Given the same level of multithreading support within various applications, does Vista direct threads differently through a dual-core CPU than XP?

Ever since I built my new 64-Bit AMD Dual Core X2 4400+ rig

Should I just dump Vista and install XP onto this new system of mine?
What good does Dual Core do anyway? I don't seem to see much benefit?
And what about this 64-bit stuff, what kinda improvement should there be?

For reference: I used Windows XP 32-bit on my system before switching over to Vista Ultimate x64.

1 - I do still have some performance hiccups sometimes when just using my computer like playing media files, there will be a little pause in the middle of a song, for example. Overall though, I actually feel Vista is smoother in use than XP was, but I think part of the reason is because I am using 4 GB of RAM. I would suggest keeping Vista at least, but you may want to dual boot with XP.

2 - Dual core is great for multitasking. Improves system responsiveness since the system can balance work between two CPU cores, so if you are playing a game and encoding a video at the same time, you will not notice much of a performance loss. If you are only gaming, the benefit will not be as great because many applications and games right now are still programmed for single threaded execution. Some applications benefit greatly from multicores, like some scientific and mathematics software. Personally, I like to encode multiple songs at the same time that I rip from my CDs. Makes short work of the hundreds of songs I have to encode at a time.

The computer I'm using now came with Vista Home Basic just shortly after it was released, but various things about it drove me crazy (particularly constant freezes and incompatibility with my software), so I formatted my hd and installed XP, but now that SP1 is coming out (and I'm sure many other updates have improved Vista) I think I might try it again. BUT, I have a question concerning the Dual-Core, Two Physical CPUs thing. It kind of confuses me, and I'm having a hard time following the stuff I'm finding online.

The CPU I'm using is an AMD Turion64 x2 (the rest of my specs are in my sig). I know that some versions of Vista support two physical CPUs and some don't, but this is dual-core, not two physical CPUs, so I don't know if that's an issue.

if i have a dual core cpu, will vista run faster because of that?

Answer:will vista make use of dual core processors?

I don't think it will really because the OS really doesn't need that processing power alone. Maybe if you are doing a lot of things at once then of course it will run faster. But the OS itself will probably just run on one core. The advantage of dual core is really to multitask and use highend apps that can distribute the load.

Hi All,

I've been wanting to go to Vista for quite some time, so I decided to finally take the plunge and picked myself up a copy of Vista Home Premium 32-bit (System Builders OEM Edition).

Installed ok. Love the OS. Could not load the ATI Catalyst 7.2 drivers (file name 7-2_vista32_dd_ccc_enu_42852) Well, that is not completely correct. The installer completed, but I ended up with an Error Code 43 in the device manager upon reboot, and the ATI CCC states "No ATI GPU is installed on this system"

So off to Google I go, surfing with the Standard VGA driver, can barely scroll down on web pages in IE7 because the GPU performance is so terrible. I finally find the following article on ATI's website:

737-24498: Windows Vista: Code 43 Error in Device Manager in Systems with ATI AGP Cards and Nforce3 Chipset Motherboards

Attempting to install the graphics driver on a system containing an NVidia NF3 chipset and an ATI AGP graphics adapter may result in the driver failing to install and the 3D engine not activating.

In Windows Vista 32bit or 64bit versions, the Device Manager will show a (!) mark and the AGP card will operate in PCI mode only. When the properties of the device are shown, the error code will show as code 43.

Thanks to you good people, I made a decision that Intel Pentium Dual-Core Processor E6700 3.20GHz is better than Intel Core 2 duo E6700 2.66GHz.Now I have one more question. My Motherboard is HP 0A54h, the chipset is Intel Q965.

The highest for it was model E2220 2.4 GHz (at the very bottom of the page).Does that mean it will not fit to my motherboard?

You must select a CPU that fits the socket.The 775 is called  LGA 775 socket has been superseded by the LGA 1156 (Socket H) and LGA 1366 (Socket B) sockets.That means newer CPUs do not fit the 775 and you must limit your selection to the older CPUs made for the 775 socket.

HiI found this tip on another forum and it speeds up my startup dramatically as Vista defaults to only using 1 core on bootup .... BUT ... a slight problem is that it gives an error and switches to selective start up rather than normal .. you'll probably see wht I mean when you try.If anyone can solve this please let me know .... hre is the tip :************Go to the start menu find msconfig, if vista type in the search box click continue it might take a while to load up the system config, click on boot tab then click on advanced options and under number of processors select 2 to 8 depending the number of cores you have like a core 2 duo you have 2 so you select 2 then it will ask you to restart after you apply the options what this does is it utlizes all for your cores when it boots you may notice a bit of difference i have a core 2 duo and i saw a diffenence vista defults on 1 core apperently you can do this on xp i dont have a dual core on my xp runner but go ahead and try it.*********

Answer:Speed up Vista startup dramatically on dual core

I'm buying a new desktop - HPa6000n, an AMD 4200+ dual-core processor (I believe) with Vista installed - to replace my malfunctioning computer, which has a single Pentium 4 processor. I've used Partition Magic 8 to create three partitions: one for my C drive, with operating system and software programs; a large one (N drive) for Photoshop projects (with Photoshop itself in the C drive); and a third, smaller one (M drive) for all Word and other text-related files. I'm thinking of doing the same with my new computer, but is that necessary with a dual-core processor? I getting the impression on the posts that Partition Magic 8 will not work with Vista. Any suggestions on what to do here (and how to do it)? Any other possible software conflicts I should be aware of, esp Photoshop, Spider2 and other graphics-related software?

Thanks in advance.


PS: No lectures please on the computer I'm buying. For better or worse that's what I'll be getting. Upgrades to RAM etc will follow.

Answer:Dual-core processor AND Vista AND Partition Magic - compatible? necessary?

One I can confirm does work for sure is Photoshop - use it on mine with no problems. As for partitions, I wouldn't bother - just get another HDD to put your data on. With modern systems that have their recovery data on a hidden partition you're better off leaving the main drive well alone.

My current hard drive seems headed for failure, so I'm considering buying a new one and installing a clean install of either XP or Vista. My question is what I can expect if I go with Vista - does this machine have enough RAM and Processor speed to keep me from throwing it out the window, or am I in for alot of grief?. Should one expect a nightmare obtaining drivers etc., or do the Toshiba install DVDs generally work smoothly?

The machine is a Toshiba Satellite A100 with Dual core 1.6 GHz and 1 GB of RAM. I'm not sure how to determine what video card I have, but under "Display Adapters" in the Device Manager it says Mobile Intel 945GM Express Chipset Family, if that helps?

The issue you're facing is a combination of a Vista "bug" and the video drivers. If you are using the latest video drivers, check to see that Vista is not managing the TMM - Vista has a bad habit of just remembering the initial setup, therefore when you take your computer off the dock, Vista doesn't like the change and will "conveniently" forget any variation of settings you may introduce.Read this article on TMM for Vista  (.doc file - read the first section)Hope that helpsMessage Edited by icantux on 04-28-2008 08:34 PM

I am considering doing a new system build and moving to vista. Right now I am on a dual core xp machine and remember sometime in the past that xp has the ability to assign which core to use to open a program. I just went back to an old MMO I used to play (lineage 2) and am trying to run 3 clients of the game in windowed mode. It is running slower than I'd like which is one of the reasons why I was considering going to quad core and vista 64 to make use of more ram. I was wondering if I can simply create 3 shortcuts for the game and add the line to specify which core the game will be opened on or if there was a way to check to make sure that each core is only trying to open one instance of the game? I would assume that opening 3 of the same thing which takes up a lot of resources would automatically get assigned to different cores, but do not know how to check that. If for some reason I cannot just do the shortcut idea and tell it to open on different cores could I create 3 folders so just have 3 copies of the game on the harddrive and then achieve the different core idea?

Hi guys. I've been looking at 2 laptops, they are basically identical but one has an Intel Core i3-4005U mobile processor and 4GB of RAM, and the other one has an AMD A4-5000 mobile processor and 6GB RAM. The guy at the store and a couple other people I know told me that the Core i3 is better than the A4 as the AMD "Quad Core" processors aren't very good, so even though the Intel i3 is only dual core it will be better than the quad core AMD. The other question is the RAM. Is 6GB that much better than 4GB or will 4GB be fine for basic use. (That's all this laptop is for. Basic use and touch apps since it will be touchscreen)

The AMD laptop is this one: Buy the HP Pavilion Notebook - AMD A4, 6GB, 15.6 at
And the Intel here: Buy the HP TouchSmart 15.6 Notebook PC - F5W37UA#ABL at

Last question, what the hell is DDR3L? All the new laptops have it nowadays... Is it backward compatible with normal DDR3 laptop RAM? Meaning can I take a normal laptop DDR3 4GB stick out of my dads laptop and put it into the 4GB (i3) laptop if thats the one i'm gonna get? Or does the DDR3 "L" part cause issues?

Edit: Sorry i'm not sure if this is the right place for this thread. If it isn't mods could you please move it? Thanks

Answer:AMD A4-5000 "Quad Core" vs Intel Core i3-4005U Dual Core

Hmm, I guess you should read some reviews. But just from the specs the AMD has 6 GB ram instead of 4. Has a DVD burner where the Intel shows no optical drive. It only has W8 8.0 where the Intel has 8.1. But some people may prefer 8.0.

Read reviews. See how each performs. If you don't wish to use it to burn DVD then the optical drive, or lack thereof may not matter to you.

Edit: Oh, and the AMD is about $80 cheaper.

I don't know if this question has been answered here or not because the words are a little difficult to do specific searches for. I am thinking of making for myself a file server. It's going to be cheap because it's main purpose is the processing of files from a centralized location. As such, I know I want processing power; but, I know I don't need a Core. As such, I'm sticking with a Pentium. I got the choice narrowed down to a Pentium Dual-Core. But, as I was researching the Pentium, I found out that the Dual-Core was re-branded to just a Pentium with dual-core features. My main question is is there a difference between the Pentium Dual-Core and the Pentium with dual-core features? I'm choosing between an ASUS P5G41C-M LX and a P5KPL-AM EPU. I wouldn't have gotten confused except that I'm buying these off of NewEgg and one motherboard has the Dual-Core capitalized while the other has the dual-core in lower cased letters.

Greetings. Hoping someone can help with reformatting a Dell Inspiron 1721; 3 GB RAM; 250 GB HDD; Athlon 64 x2 Dual Core 1.9 GHz processor; Vista Home Premium 32 bit OS.

Reformatted and clean install of Vista 2 months ago. Afterward, everything worked perfectly until a couple of weeks ago. After automatic updates installed Vista SP2, suddenly Windows Media Center (which I've never used and am not at all familiar with and have no plans to learn it and use it in the future) began opening by itself over and over.

Also, a little window popped up on boot up that said something to the effect that my new hardware needed intalled; however, I have not added any new hardware. Have no idea what it was trying to install.

Also, intermittently, programs I'm using just exit out even though I have not pressed exit. And, the mouse intermittently jumps around by itself or won't respond to the touchpad - - it opens programs, opens the start menu, types gibberish into the 'Start Search' line, closes programs, opens browsers or browser tabs, closes browser tabs, etc, etc, etc.

Also, sometimes an odd looking exit menu appears top left screen in a different resolution than the screen is set at. AND, sometimes, when I'm working, all of a sudden the keys won't type but the computer issues a loud beep every time a key is pressed.

When problems first started, I immediately ran system restore. No change.
Tried another date in system restore. Still no change.

Hi Sharon.

If your game then so am I.

All the things you stated sound like a possible infection or operating system corruption due to unknown reasons. Although none, or a questionable one, was found. I am in total agreement with Garmanma. Also the fact that the rootkit scan is disabled in AVG causes me some concern.

Seems you already have a pretty good idea how to format the drive and reinstall your OS and drivers....... But would like to take it one step further in this case though. I would like to have you wipe the entire hard drive to zeroes prior to formatting and installing the OS. This would include what is called the MBR = Master Boot Record, the partition the OS is on as well as the restore partition. Of course this would leave you only the option of reinstalling via the CD. All pre-installed software will be gone for good. Complete restore CDs are usually available from the OEM for a nominal cost.

The only reason I suggest this manner is, 1)The problems you are describing does somewhat resemble infection symptoms. 2)Depending on the possible infection type a simple reformat may not get rid of it. I have also read that it is possible for the restore partition can become infected as well.

The procedures are really pretty easy, the program(s) to wipe the drive to zeroes is free and we will do our best to get you through the whole procedure as painlessly as possible.

Let me know what you decide.

I don't think there are any Celeron Processors which are dual core and so the Pentium 4 will definitely be faster. If you give me model numbers I might be of more help.

Hi, Currently I'm using a dual core 6850 and I'm thinking about buying a quad core. I have a PSU of 500 W as spare.

Can i replace the CPU to a Quad Core without changing the cooling system?

Answer:replace dual core CPU by quad core what about heatsink? in Mini Tower 755 Optiplex

These are the specs of the spare PSU. Aren't they better than the original Dell PSU?
That power supply is ATX and not EPS12V
Better is not the issue.  Dell power supplys are 80 percent efficient not 70 percent ATX.  The -5v rail is an issue as well as this may cause a motherboard fire or damage your system.  Its a dead giveaway that this is a power supply from 1990 to 2000.
What current is on which rails is not trivial. There is a single 12V RAIL on that unit and its max is 17A
EPS 12V units have multiple rails of 12V @ 18 amps each.  MAX Power on the 12V rails is 264w not 204w
That unit has a lot more on the 5V and 3.3V rails at the expense of the 12V rails and CPU 4 pin connector. So no that spare unit is not likely to work well if at all.

Recommended update or replacement is EVGA 750B1

But, if I use the numproc=1 statement and run my PC as single core, it stays perfectly stable for week+.

Hello friends,
I m very eager to know that whats the actual difference between a Core 2 Duo processor and a Pentium Dual Core processor, other than their proceesing architecture?

According to most benchmarking sites including Tom's Hardware, Core 2 Duo E4300 or 6300 performs better than Pentium Dual Core 820 in almost all benchmarks.....whereas C2D E4300 or E6300(1.8 and 1.86 Ghz respectievely) are having MUCH lower clock speeds than Pentium D 820(2.8Ghz). Why like this???

I have 2 systems, one with C2D E4300 1.86 Ghz and another(from which I am writing this thread) is Pentium D 820 2.8Ghz. But I dont see any MUCH performance difference in reality, although in multi-tasking and gaming C2D system still performs better.

Can anybody please explain me in details.....
Thanks in advance.

Answer:Why Core 2 Duo outperforms Pentium Dual Core even when C2D has lower clock Speed??

The Core 2 Duo doesn't share the same architecture as the older NetBurst architecture of the Pentium D, which is also shared by the Pentium 4. The Pentium D is effectively a pair of Pentium 4 CPUs on one die. The Core 2 Duo architecture allows for a lot more processing to be done in one cycle, hence more information can be pushed in, say, 1 million cycles by the Core 2 Duo than the Pentium D. As for 'reality', there obviously won't be much difference when both systems are used for stuff like playing music etc. But the real differences will show up when you tax them, such as when playing an HD video without a video card supporting HD-decoding where the Core 2 Duo will be able to process information much more quicker than the Pentium D and so you will have a smoother image. Check on Wikipedia for more in-depth details.

Hey all,
I have some proprietary software that works great on a single-core processor. When I try to run it on a dual-core or above, the software loads, works once, and then messes up.

The software uses modems to dial out to our payphones. We found a work-around by turning off one processor in the bios, but then, what's the point of having a dual-core processor.

Please help. The software is doing this on Windows XP.

Wasn't sure if I should put this on this forum or the operating system forum, but here it is.

So I'm building this awesome computer with Core 2 duo. Now it says something about vista isnt fully compatible with dual processors or something.....This statement is what I"m curious about, "While all editions of Windows Vista can support multiple core CPUs, only Windows Vista Business, Ultimate, and Enterprise can support dual processors." So I'm going to buy Vista basic, I can still put it on the core 2 duo system, right? And whats that statement mean?

Answer:core 2 duo and vista....silly question..need reassurance

you can still use it, you probably wouldnt get as much of a performance gain as with the versions that will use both cores simultaneously. I hope you plan on having at least 2 Gigs of ram and a really good video card for all that background stuff that vista has. Before you choose vista make sure you do enough customer reviews on the product and not product reviews in general.

OS = Windows XP 64bit w/sp1, Mainboard=Epox 9NPA+Ultra, CPU=Opteron 170

I currenty have a Dual Core CPU - If I wanted to switch back to a single core CPU - what would need to be done to do it correctly? I already tried it as a quick test with a spare harddrive - it booted up fine BUT it still said "ACPI Multiprocessor PC" under "COMPUTER" in the device manager and I couldn't see a way to change it. Is there a trick to getting it to revert back to the "ACPI Uniprocessor PC" ??
I guess a second part to that question is - if I made the switch, do you think it would cause my Windows Activation to reset?


Answer:Switch from Dual core back to single core process

This is all theory and speculation, as I haven't tried this myself...

1. I believe you *can* switch from multi <-> single in windows, I think you're better off just reformatting... much like it being a rather poor idea to upgrade windows from one version to the next.

2. I'd be very surprised if your activation reset because you swapped out the processor.

In May, I noticed my laptop was running slowly. I asked for help from another forum and they suggested I downloaded a program called Speccy. After running this program, which I have used before, I noticed the processor was only using one core. This might be fine for a regular user however, I need my laptop for University work as I am a networker.

I have had to change windows 7 to the most basic settings to get any decent performance from it. I used to be able to watch full HD videos from my hard drive on my laptop with out any troubles. Now it barely even plays the same films.

Does anyone have any ideas? I have also gone into msconfig and cant specify how many processors are set to run.

Answer:My Satellite L750D has gone from a dual core to single core processor


The CPU?s core multiprocessing can be enabled and disabled in the BIOS.

The option can be found in BIOS -> Power Management tab and it?s called CPU Multi-Processing
If it?s enabled, all the CPU cores will be used.

Furthermore be sure the Dynamic CPU frequency mode is switched to ?Dynamic Switch?

If this option is enabled, the CPUs power consumption and automatic clock speed switching functions are enabled.

I have two laptops made by the same manufacturer and same year, but one is a dual core laptop with an SSD harddrive and the other is a quad core laptop with a regular hard drive. Both laptops run Windows 8.

I would like to transfer my programs and files from the dual core to the quad core. However, obviously the quad core has different hardware.

I am wondering if I simply remove the SSD from the dual core and put it into the quad core (replacing the quad's primary hard drive with the SSD) and simply boot up the quad core, would that be sufficient? Will the quad core recognize the hardware mismatch and automatically correct the drivers, while keeping my programs and files?

Or is there some other, efficient way to make the transfer? I really want to avoid having to reinstall all my programs.

Thank you

Answer:Transfer programs and files from Dual Core to Quad Core

There are a lot of third party tools designed to move a Windows installation to new hardware. I prefer using native Windows tool Sysprep for this, mainly because the method is the one and only Microsoft supports and recommends but also because it has never failed me.

The method is described in this tutorial on our sister site the Seven Forums and works also with Windows 8: Windows 7 Installation - Transfer to a New Computer - Windows 7 Help Forums. Method One in tutorial would be ideal for you for moving the SSD to new computer.

Read the information and warnings in the beginning of the tutorial carefully, especially the warning about Windows needing to be reactivated is important. Come back if you have any questions.

Just a quick question. I know daul core means two cores on one chip. But if you have a 2.0ghz daul core cpu dose it mean you are equal to or better than a 4.0ghz
cpu? People keep asking me this. They want to know if they have a peice of software that requires a 3.0ghz cpu and they have a 1.5ghz daul core if they can run the software.
I'm just not understanding single core to daul core thing completely and i am not sure if i am answering them correctly. I think so but just want to confirm.

Answer:Core 2 duo, dual core, and Athlon64 X2 Dual Core

No. It simply means you have more than 1 CPU on the die. A 4 core 2.0 CPU means you have four (4) 2.0ghz cores on the die.

At this point, just because a GHz is faster doesn't mean the system or the die is faster or slower than others. There are many things now that affect speed - ram (or lack thereof), the efficiency of the programs to multi-task, HD rpm, chipsets, and others. The trend to faster GHz CPUs with single cores ended a couple of years ago as CPU makers discovered they ran into a thermal barriers with smaller circuitry that they couldn't get around. So they decicded it would be better to put more than one CPU on the die. Thus we got multi core CPUs. Yes- even here they are trying to make each core faster, but there is still a thermal barrier.

For the most part, you really won't notice much of a difference in speed after a certain point. - You have to take the whole system together. Gamers need to pay special close attention to their graphics cards and RAM.
