Preferred Solution: How can I disable signed driver checking in Vista x64 SP2?

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.)

I am having a heck of a time. I have installed Windows Vista Home Premium 64 Bit and the ASUS P5QC mobo I have came with an unsigned 64 bit Atheros AR8121/AR8113/AR8114 PCI-E Ethernet Controller

I called ASUS tech support and talked to them and as of this time, they have only a beta version of the 64 bit signed driver. Vista is not accepting the driver and is considering it as unsigned, so I am left without a computer that can connect to the net.

I have searched hi and low all over the internet to see if I could buy a wired ethernet adapter which has a 64 bit signed driver, but all of the ethernet cards I have been able to find are only compatible with the 32 bit version of Vista or they only have unsigned drivers for their ethernet cards. This is really frustrating!

Does anyone know here WHO (what manufacturer, make, model) of a wired ethernet adapter card 10/100 or 10/1000/1000 (that does not cost a fortune - is retail version, not industrial or commercial)

Only been here an hour and already on to my second problem, lol.

So my only other problem is one little hardware adapter that has 64bit drivers... but they're not signed.

Is a "Syba" Serial to USB Adapter (SY-USB-S)...

basically I need to use it so that my battey backup can talk with Windows and give reports on power spikes etc... as well as control the shutdown of windows when I'm not around if there's a power outage.

Now, it's not a huge deal as the battery backup will still work of course, but the extra features won't work until Windows can communicate with it. Unfortunatly the backup only as a serial connection (and my motherboad doesn't) so I'm forced to use the "Serial (RS232) to USB" adapter.

So I'm wondering a few things.

1) can I force Vista x64 to use the unsigned driver from the company?

2) can I trick Vista x64 into thinking the driver is signed? (or someone mod the drive to that it is signed by me?)

3) Anyone know of a signed driver from another company that will work with this item? I assume a few companies use the same chip inside the device. All it does is make a bridge from USB to serial so it's a pretty simply device as well.

4) Anyone know of another Serial to USB adapter that has singed drivers that I could purchase to replace the current one?

Thanks again for any advice or help,

I have been trying now to install drivers for my Panasonic Digital Camera, which installs itself as a ZIP drive (it uses a 3.5 100MB ZiP disk instead of memory cards), and Fusion Dazzle which is an analog to digital convereter. Both plug in via USB. They used to work perfectly until I had to reformat and reinstall Windows on my computer.

I now get an error message that it is missing certain files (which ARE on the system) and it is looking for "C:\PCLEUSB.drv". When I point it to the correct driver location I get an error message saying that this driver has not been digitally signed to be compatible for Windows XP and will now exit installation.

I am using the most current drivers from the manufacturer and they say that they are Windows compatible and I am the first to have this problem. So far, they have been unable to assist.

Any suggestions?

"Not digitally signed" means Microsoft have not tested this driver and verified it to be compatible with Win XP.  This does not mean it will not work, you should click on the "continue anyway" to install your print driver.  If this is a concern you should check the HP web site for newer driver tested by MS.Kim

I'll try to keep this brief:

> Upgraded GFX cards to 2 x Asus EAH4980 (ATI Radeon HD4890 architecture) from NVidia 8800GTS

> Performed full format on HD and reinstalled Windows Vista X64 Home Premium as well as SP1 and SP2

> Installed chipset drivers etc.

> Installed bundled VGA drivers (8.592)

> Installed miscellaneous software/games

System was running very stable and performing well in Benchmarking tests and games. I then tried to update the VGA drivers to the latest versions, first from ATI's own website - Catalyst 9.8 with VGA driver displayed in Device Manager as 8.640 - and then from Asus' website - displayed as 8.630 in Device Manager.

No matter what drivers I update to I am met with BSOD errors as soon as I try to run any kind of media on my PC. The dump files/dxdiag info etc. is attached to this post.

I recently got a docking station for my laptop (Dell precision M65 w/WinXP Pro SP3 all updates) and when I plugged it in (after all the plug-n-play stuff detected the new docking station stuff), the mouse plugged into the dock USB port would not work (it worked fine previously when plugged into the laptop USB port). I undocked and plugged the mouse back into the laptop's port but it still didn't work.

I went into the device management applet and and tried to update the driver. There was nothing under "Mice and other pointing devices" except the PS/2 touchpad. Under "Human Interface Devices" there was an entry called "HID-Compliant device" If I deleted that device and then did a "scan for hardware changes" I would get the "found new hardware" popup in the tray and then breifly see "Dell USB Optical Mouse" during which the mouse would work but within 2 or 3 seconds it would switch to "HID-Compliant device" and then inform me that my hardware was ready to use at which point the mouse stopped working.

After much screwing around with the device manager and various other USB mice, I found that I could use the "Update Driver" right-click menu item to force the driver to "HID-Compliant mouse" by bypassing all the "Automatic" stuff. This resuted in a working mouse, but I have to do this every time I turn on the laptop.

Hi, I finally have my File System mini-filter driver working great, and tested it a lot on Vista 64-bit using the testsigning boot option. All was fine.

However, when I turn testsigning OFF and try to start the service (the driver), I get the StartService failed with 577 - windows cannot verify the digital signature. Note that the driver in INSTALLED, and the Registry is updated, etc. I just can't start the service (even when running as Admin).

It is signed using a Microsoft cross-certificate, based on the original certificate issued by GlobalSign, as directed in MSDN. You can examine the certificate using the driver's properties, and all looks fine.

I also tried installing the certificate, but that made no difference. This should all be correct, except that it doesn't work!! Any idea what is going on here? Any help would be greatly appreciated! I thought I was all done with this project, but since it doesn't work, I am currently screwed. THANKS!

Can I get around this?

Answer:Required Digitally Signed Driver?

Uhmmm... yes, you can by pressing F8 at boot time and choosing to ignore the warnings about unsigned drivers, but you have to do it each and every time you boot. There is a way to permanently disable that driver signing requirement but I'm leery to give out the info anymore since it hosed a few people's machines recently.

It wasn't my fault that they chose to continue using shitty old drivers, but they blamed me for the mistake they made anyway.

Vista x64 is a more secure and stable OS than the 32 bit version, and that's one of the primary reasons why: the driver signing requirement. Disabling it or 'getting around it' will more than likely end up causing you issues at some point.

Google can find the specific method to disable the signing requirement permanently, or a search here might find it since it's been posted about 3 times over the past 4 months or so.

Good luck, either way...

The reason i ask is because when i look at my drivers through the DirectX diagnostic tool 's display tab it shows my driver as 'nvdisp.drv' and in the 'notes' sections adds :

" The file nvdisp.drv is not digitally signed, which means that it has not been tested by Microsoft's Windows Hardware Quality Labs. You may be able to get a signed driver from the manufacturer of the hardware device"

but when i look through the ASUS home page i can't find my video card.

If you have a computer that is running Windows 7 or Windows Server 2008 R2 and you install a driver that has a Windows Hardware Quality Labs (WHQL) or Authenticode signature on the computer.
But in Device Manager, when you expand the corresponding device, right-click the driver, and then click Properties and then click the Driver Details button on the Driver tab, you may find that the driver file is displayed as unsigned! This issue occurs because of incorrect logic when the Authenticode flag in the catalog file of the driver is checked.

I recently purchased a new pc that came with win vista 64 bit premium home installed. I am now reloading all my old programs and I keep getting ?windows requires a digitally signed driver" error message. I also can't seem to play my old movie files, all of which played fine when I had Win XP. Apparently Vista does not want me to make my own decisions, so I am wondering how I might go about disabling all this extra secure vista crap. Can I go into Control panel and disable the BitLocker Drive Encryption? Or do I need uninstall 64bit and install the Vista 32 bit? Would that be a smooth transition? Would all my stuff work again if I had the less securitized 32bit Vista? Thanks for any help you may provide.

Answer:windows requires digitally signed driver

Welcome to the Vista forums

1) You don't want to disable UAC (User Account Control) as it does a lot to protect your computer from various malware. If you really feel the urge to turn it off, then you can in control panel in the User Account section. Once turned off, you'll get the red shield in the bottom right saying it's disabled. Disable security warnings by opening security centre and going to "change how security centre warns me" or something and choose the "no warnings" option.

2) Just download the Vista codec pack (just Google it and you should find it) and DivX and you should have no problems watching videos.

3) You can install unsigned drivers on Vista 64 bit, do this by running an elevated command prompt (right click on command prompt in Start menu and click "run as administrator".

Type this and press enter bcdedit /set loadoptions DDISABLE_INTEGRITY_CHECKS

When you reboot, you should be able to install unsigned drivers.
Also, I looked on the HP website for your computer, and it has 6GB RAM, so going to Vista 32bit would only allow you to use about 3.5GB RAM. I also saw it only has an Nvidia 6150e onboard graphic card. Are you using this? As if you upgraded this to a graphic card, you'd notice better performance on Vista as well.

This takes ages. Tried going into the BIOS and setting Client Security to both Disabled and Inactive. I also disabled cssauth in my startup and that didn't work either.

Answer:Need 2 disable "Checking the Status of the Embedded Security Chip"

The most efficient way of stopping this message is to remove "Client Security Solution" from Add/Remove programs in the Control Panel. Going in the BIOS and trying to remove it in safe mode will NOT fix this issue. I know it's painful waiting for it to check that status each time, but this is controlled directly by the CSS software itself. Hope this helps.  Mark

My harddrive went out and I put a new one in. It was a brand new drive and I loaded Windows 7 Home Premium 64bit from my laptop's recovery disk that came with the inital purchase. When I started to add the drivers 2 of them came up as unable to verify the signatures. Most importantly the driver for my Wifi adapter, which is an Intel Wifi Link 1000 BGN says this. Windows refuses to run it in that state. So I have no internet and it says that the adapter is not installed or is disabled. When I go into the Device Manager the adapter is there with a yellow "!" and has an error code 52 (for unsigned driver). It shows installed and enabled though

I installed the driver from the intial driver disc and it says unsigned, I was able to get the latest driver from Intel's website and that too says it can't verify the digital signature.

When I boot into the F8 screen and disable driver enforcement I am able to get online.

I'm not sure if this is related or not, but regardless of how I boot, Windows updater and troubleshooters do not work.

I'd appreciate any help.

I have x220 with Windows 7 Pro 64 bit. Device manager shows under Storage Controllers "Ricoh PCIe SDXC/MMC host controller," but there is a yellow triangle with "!" and a Device Status Code 52 message "Windows cannot verify the digital signature for the drivers required for this device." I checked in C:\Drivers\WIN\Multicard and found two *.cat files--which, I understand, are required to confirm digital signature. Each of them ( and has a signed and valid certificate! So what is going on? Will the card reader work? Is there something wrong with how Windows 7 is treating the Ricoh driver, which I downloaded from the Lenovo site? Why should I be getting this grief?

Answer:Ricoh card reader driver-not digitally signed?

Try deleting the Ricoh PCIe SDXC/MMC host controller from the Device Manager and then restarting the computer in order to let the Device Manager re-detect it and re-install the device drivers.  Does that solve the problem?

I'm at my wits end. Anyone who can help would be my hero.

Acer 5253 laptop, Win7 Home Premium 64bit SP1, AMD C-50.

Trying to use a USB mouse. I have 3 logitech mice. None work because hidclass.sys and hidusb.sys are not digitally signed. If I f8 and disable driver signing enforcement, all 3 mice work, so I'm pretty certain that's the issue.

Tried "Update Driver" via device manager. Windows determined that I already had the best driver and wouldn't do anything.

Logitech does not furnish drivers for Win7. They rely on the native drivers.

Acer does not furnish mouse drivers. They refer you to the manufacturer of the mouse.

Tried copying the files in question from a 64bit machine that showed them to be digitally signed. Renamed the ones on my machine and pasted the ones from the "good" machine. Resolved nothing.

chkdsk /r found problems and repaired them. Didn't help.

sfc /scannow found problems that it could not resolve. Looked in CBS.log and found no references to either of the sys files in question. No resolution.

System Restore only had one restore point, and it was from 2 days ago. Problem was already noticed by then. I suspect that it's been this way since I purchased the laptop a couple of months ago anyway, but if there had been a restore point back at the very beginning, I'd have tried that.

Windows Vista x64 decided to implement a 'security measure' by which all drivers must be 'digitally signed' to be allowed to install and run. I have a program which is compatible with Vista and x64 bit operating systems, however as its drivers are not digitally signed I cannot run it correctly - I recieve the message 'Windows requires a digitally signed driver' and access to the driver is blocked.

Is there a method of bypassing this?

When you boot your system hit F8 and you can bypass it there. You will have to do this every boot. There are a couple applications out there that will do this for you but the names escape me right now.

This is my first post on these forums, so please excuse me if anything is wrong.

Details of the problem: I have a Sony VAIO laptop that runs Windows 7 Home Premium x64. I recently downloaded the same version from digital river that has SP1 included and installed it on my laptop. I installed the drivers that I had downloaded from sony's esupport site which went fine. After I rebooted and tried to install the rest of the drivers, I started getting the Code 52 error: Windows cannot verify the signature of this driver. I've seen that every driver can be installed immediately after the system has been booted the first time (after a clean install). Once rebooted, it starts giving the code 52 error. I can't install my iPhone drivers (through iTunes) or PS3 utilities because of this. I'm wondering what changes during the first reboot. I must also say that these very same drivers were used on the previous build of Win 7 HP that I was using except that it did not have SP1 integrated.

Has anyone had a similar experience? I know that the digital signature check can be disabled using bcdedit.exe but I want Windows 7 to work the way it should: it should stop me from using unsigned drivers while installing signed drivers correctly. Does any one have any clue to what's going on with my Win7 on my laptop?

Hi ajayav, Welcome to Sevenforums.

Boot into Advanced Boot Options and disable driver signing checking.

The Advanced Boot Options screen lets you start Windows in advanced troubleshooting modes. You can access the menu by turning on your computer and pressing the F8 key before Windows starts.

Disabling driver signature enforcement has helped a lot of users in fixing the issue.

You may also delete the USB "Upper Filter" & "Lower Filter" Entry and check if that helps.

Why is everyone saying Vista 64-bit won't install unsigned drivers? I installed the latest beta driver from nvidia and Vista warned that it was unsigned but gave me an option to install anyway.

Am I missing something/misinterpretting this or was this only the case in the Beta/RC verisons of Vista and everyone keeps bringing it up (kind of like requiring UAC for changing backgrounds; people still say Vista does it)?

Answer:Digitally signed drivers required under Vista 64-bit?

Short answer: The effects of FUD.

Long answer: The truth is, it was never stated on any official documents that Vista wouldn't accept unsigned drivers. The real mechanism is how Vista handles such drivers, in that the permission level changes, but that's such a 'behind the scenes' object that some ppl though it cooler to just say, "NOEZ, the sky is falling!".

So I have IE7 on Vista. When I try to access the website I get an error "internet explorer cannot access the webpage". It should be saying that there's a problem with the certificate, and let you decide whether to go on. IE7 can open some other secure websites.I did a lot of surfing trying to figure it out. It seems like the problem is that this webpage has a self-signed certificate, and it's not signed using RSA algorithm, it uses SHA1.IE7 on Windows XP accesses the website fine. Apparently IE6 also works. I think this is the problem because I found the problem described online in 2 places, another website. I had tried a lot of suggestions I found online and none of them worked. I installed all the updates I've received from Microsoft. It's apparently a bug in IE7 on Vista. If anyone else has IE7 on Vista it might be interesting to see if you get the same error trying to get to this webpage. I have the version of IE7 that came with the "upgrade" to Vista. I wish I'd stuck with Windows XP. Laura

Question: Driver Checking

What is the best way of checking that drivers up to date.

Answer:Driver Checking

If its working, don't fix it.But if you need to check get into 'device manager', Control Panel, System, Hardware, Device Manager.From here you can right click on any hardware installed, click on the properties, then the driver tab to check the date and version number.Once you have this information go to the hardware manufacturers website and check for any new drivers.Alternatly, on the drivers tab click 'update driver'. Windows will ask if its ok to check the internet for any new ones. Follow any prompts that appear.I would suggest that if you are using win XP you set a system restore point before updating any drivers, just in case new ones cause a problem.

From what I've read, most of the problems people encounter with Vista are driver and support issues.

So before switching, are you checking all your hardware manufacturer websites to make sure that they have vista drivers out?

Or is it Vista drivers are being supplied and there are still issues?

I've not switched yet, and have been toying with the idea, but when I have the money and am prepared to spend it on a new os, the first thing I'll be doing is hitting up Nvidia, creative labs and evga's websites to make sure I got drivers for it.
On a side note, is it likely that the longer I wait, the cheaper I will be able to get Vista for? Also, the longer I wait I am assuming the better the hardware support will be.

Edit: Can the same thing be said for Ubuntu, as far as verifying linux drivers to ensure a smoother time when switching?

Answer:Checking driver support before switching OS's

Vista probably won't drop in price very much, if at all for quite some time. You're best bet is to look for the drivers ahead of time, as you said, and also look into your applications compatibility. I had been using an older version of Diskeeper that didn't work in Vista.

The PC freezes completely, this happens completely randomly sometime during boot, or right after boot or every 5 to 20 minutes. I have reinstalled the OS twice, installed SP2, installed all relevant drivers but I cant get the OS stable.

I have tried removing 1 RAM chip, putting the RAM in a different slot still nothing. I have removed both the video card and sound card and CDrom and used on board video but it still freezes. When I reboot in SafeMode with Networking the computer is perfectly fine. I dont notice the CPU getting warmer then 42c so I dont think its heat either. I just cant get the system stable.

So I am going to try and update all drivers in Safe Mode(since the computer won't run log enough normally to install drivers) and then if that doesnt fix my problem I am just buying a new prebuilt PC.

I need help with this, can't quite figure out the problem. It's really... odd. In addition to other minor system problems in this brand new build, I have a somewhat recurring driver crash related to the common Driver Verifier problem. I can't find the driver myself, so I don't know which one or ones it may be. In addition, the crash most frequently occurs when using AIDA64/Everest to check my motherboard's specs. I can view most of it, including the hardware set-up, but clicking 'BIOS' or 'ACPI' to check those parts causes an instant crash. I don't know if this is normal.

I'm not so much versed in drivers or Driver Verifier, so before I did anything I wanted to come here. Also, I tried to upload my SF data correctly, let me know if you need anything else, or if I made a mistake. Thanks for taking a look.

I need help identifying which if any drivers I need updating, not my strong part past GPU updates.

I have attached a driver list.

The reason for asking is constant crashes in a game - SimCity, which crashes 10 min's into each game consistently to Desktop. Have got a suggestion to check drivers, one option I guess.

If anyone could help - it would be much appreciated, or indeed offer any further feedback.

Answer:Help needed checking which driver/s need updating - SimCity CTDT

Upload the list of all the third party drivers Using NirSoft DriverView :
Download and execute Driverview
View > Hide Microsoft Drivers
Edit > Select all
File > Save Selected Items
In the Save dialog, Set the path to desktop, Put "Driverview" in the name field, and save.
Zip the .txt file and upload it.

Hello all,

I have a Windows 7 enterprise computer in a Windows domine, the problem is that I'm trying to disable the touchpad mouse of my computer but when I go to Device manager and see the properties of the Mouse Driver the button "Disable" is disable, I think that is something with domain politics and I can enable the button modifying regedit but I am not shoure of this and I do not what key of the regedit I would have to modify.
I add a photo so you can se what is the problem becose my english is not Good.

Thank you all.

Answer:The button for "Disable" a driver in Device Manager is disable

Welcome to the Seven Forums David!

I see the same thing on a W7 Pro laptop - the same button that you have highlighted is disabled.

Try this:
Start > Control Panel
In the upper right corner, change "View by:" to small icons or large icons
Locate and click on "Mouse"

See if you can disable the touch pad from there.

I'm a relative novice to troubleshooting computers. My last updates for Vista were installed 26/07/16, KB890830 twice. The last check for updates was on 8/8/16 and my computer states it is up to date.
Now Windows Update just runs forever. I started it 10:00 last night and it was still "checking for updates" this morning. This morning I tried installing Windows6.0-KB3177725-x86.msu, Windows6.0-KB3153199-x86.msu and Windows6.0-KB3145739-x86.msu but they just go into "Checking For Updates" when  I click to run them.
Am I doing something wrong?

Answer:Vista Updates just keeps "Checking"

- Yep, the usual "Windows Update" problem. Try this guide. (It also provides instructions for Vista users). It also gives more details on how to diagnose this problem.,4799.0.html

My HP G50-109NR laptop keeps checking for updates. The last successful update was "Windows update agent 7.6.7600.25" on 5/5/2016. No updates since then. I have SP1 and SP2 installed. I ran a full scan with Windows defender, but no threats found. There are no error messages.

Answer:checking for updates in vista

checking for updates for me, it sits there A LONG TIME. Last time I checked for updates I had it sit there for an hour.. Finally, it came back with 180 updates. Just walk away.. it will eventually finish. some folks have said of hours before seeing updates to install, especially after a reinstall. see how it goes.

i have a black screen that keeps on reading checking inconsistenay c drive, ntfs volume label is os. it doesent matter what i do it keeps on reading the same thing. what to do?

Answer:Vista checking for consistency c drive

Download the diagnostic test from the hard-drive manufacturer. It may be a failing hard-drive, so I suggest testing the drive and if it is failing save your data and replace the drive. The diskcheck can be cancelled by hitting any key within the first few seconds of the scan, but the fact the scan keeps coming up can indicates a possible serious issue with the drive......I'd be checking the hard-drive.

I have a Toshiba laptop running Vista, which I have not used for a while, so I thought I would update. On trying to update via Windows Update, it just goes on and on "Checking for Updates". I presume Microsoft still do updates for Vista? If they do what can I try to fix the problem?

Answer:Windows Vista Checking for Updates

search type services.msc
scroll down the services and check BITS background intelligent transfer and windows updates are set to automatic and have started if not set them to automatic and click the start box and then retry to check for updates - the more your missing the longer it will take.

This major package was release Dec 2014 and my new machine doesn't show it installed.  I would have expected it to be part of the image build of my new system. Are we still suppose to run this update listed in dowload from Lenovo.?

Answer:Checking for some driver updates I looked into KB2934018 listed and found it not installed!!

hi tripplec,
If you see the Windows 8.1 Update (KB2919355) been installed already under the Control Panel (icon views) > Programs and Features > View Installed Updates and on Control Panel (icon views) > Windows Update > View Update History then your problem might be relevant to  this article
If you see the Windows 8.1 Update (KB2919355) or the KB2934018 being available on the Recommended or Optional updates then I recommend you install it.
Alternatively, you can also install it manually using the package below:
Windows8.1-KB2934018-x64.msu 126.4 MB

Hello all, I posted a while ago about trying to find a gaming pc. I've now decided I will go ahead and buy pieces seperate, but I'm not the chap who's building it as im clumsy and nooby :) I have 3 friends willing to build it and have built several PC's before.The spec is:Geil Ultra DDR2 2.0GB PC6400 Dual Channel memory kit (2 x 1GB) 800MHz (4-4-4-12) +Aluminium heat spreaderIntel CPU Core 2 Duo E6850 3.0GHz 1333FSB LGA775 4MB cache Retail inc.Fan (3yr Manufacturers Warranty)Lite-on LH-20A1S-11C SATA Retail 20x DL DVD +/-R/RW RAM Black/silver beige bezelsCoolermaster eXtreme Power 650W PSU ATX Form Factor RP-650-PCAPAsus Motherboard P5K-E/WIFI-AP Intel P35 LGA775 Core2 Quad / Core2 Extreme / Core2 Duo PCI-E DDR2 ATXBFG GeForce 8800 GTX OC2 768MB DDR3 PCI-E Dual DVI500GB Western Digital Caviar SE16 SATA II 300 7200rpm 16MB cache Hard Disk DriveOk. A few things. Theres no speakers (still searching on some 2.1's, undecided, but thats not an important spec) Cases are either going to be:click here(6706)ThermalTake-Tsunami-Black-Aluminum-VA3000BWA.aspxORclick here(17317)ThermalTake-Kandalf-VA9003BWS-Black-super.aspx(might be going overboard there with the fans and the price, thats what im wondering...)So thats the PC. But I now have a question of 32 bit or 64 bit Vista. I'm choosing Vista because I want to make full use off my dx10 card, and I'm planning on upgrading to 4GB of RAM either straight away or just order 4GB instead of 2GB. I've heard problems with 64 bit. I'm a gamer, s... Read more

Answer:Just checking PC design is sound+vista question

Spec looks good , memory is enough , 4gb in Vista 32bit will only show 3gb due to restrictions but that is no worry , get the 32bit version anyway as the hardware requirements for 64bit are horrendous ( all MUST have the Microsoft Designated drivers or won't work at all ) and games aren't really written to run on 64 bit as well . Motherboard has 4 memory slots , here for the full spec. I thought about DDR1066 memory , but the web site says although it can support it , they will probably be dead picky over which modules it likes . You might think about having a slightly cheaper case and getting a bigger power supply in case you wish to add a second graphics card in the future , two cards would eat a 650w psu for breakfast .
