Satellite A100-626 - Maximum system memory supported?

Question: Satellite A100-626 - Maximum system memory supported?


I have a Satellite A100-626 with 2Gb of RAM memory.

As stated in specs for this model:
standard : 1,024 (512+512) MB
maximum expandability : 4,096 MB
technology : DDR2 RAM (533 MHz)
expansion module sizes : 256, 512, 1,024 MB

It says that it can go up to 4Gb, but only shows module sizes up to 1Gb. (maybe 2Gb modules didn't existed at the time).
Anyone knows or tested if it is possible to install 2 modules of 2Gb or 1 module of 4Gb to reach the maximum expandability of 4Gb?
Also, does it supports frequency's up to 800MHz? If not, whats the maximum value?
And at last, does DDR3 work on this model?

Thanks in advance for the replys.

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.)

Answer: Satellite A100-626 - Maximum system memory supported?


I found this Toshiba product page:
[Satellite A100-626| &ACTION=PRINT_WITH_BACK&BV_UseBVCookie=yes&PRODUCT _ID=119571]

It?s a Portuguese Toshiba page because I believe that this notebook model was designed for Portuguese market.
There you can find a info that it?s possible to upgrade the RAM to 4GB (2 x 2Gb RAM).

But note; the 32bit Operating system will be not able to use the full 4GB RAM.
Just the 6bit OS can use and recognize the full 4GB

> Also, does it supports frequency's up to 800MHz?
This depends on the chipset. If the chipset would allows the 800Mhz then the memory module would run at 800Mhz? otherwise they would be clocked down.

> And at last, does DDR3 work on this model?
No, as far as I know just DDR2 modules are supprted.

I've tried searching the board and the Toshiba site, but have yet to find the answer. Please bear with me if the question has been answered elsewhere.

I bought an old A100 on eBay - it seems to work fine, but has a (non-standard) 40GB hard drive.

Entering the serial number on the Toshiba support site reveals the machine to be an A100-001.

As far as I can establish, it uses a SATA drive.

Does anyone know whether I could upgrade to a 320GB drive, or whether there is a limit to the hard drive capacity supported in this model?

Answer:Satellite Pro A100-001 - Maximum hard drive capacity supported?


If it?s SATA HDD controller then you should be able to use 320GB HDD and bigger?
As far as I know the SATA controller has no limitation and therefore it should be possible to use such big HDDs sizes.

Hope I could help you.

I have an old Satellite A100-811 with Windows XP SP3. It has 1 GB memory (2x512). I want to upgrade the memory. What should I do?

1. Put another 2GB memory so the total is 2.5Gb (will i have any problems for using two types of memory 512Mb and 2 Gb ?)

2. Put 2x1 Gb total 2 Gb (for better combatibility?)

3. Put 2x2 Gb . But will i have the full 4Gb memory or just 3Gb because of Win Xp limitations of memory?

Do I need any BIOS update for this?

Thanks in advance for any info!

Answer:Satellite A100-811 - Maximum memory capacity

Hi skga100,

The maximum RAM capacity of Satellite A100-811 is 4GB. That means you can install 2GB in each slot.

Usually for Windows XP 2GB is enough but I you want to upgrade to Vista or Windows 7, you should think about 3 or 4GB?

In your case I would buy one 2GB memory module. So you are on the safely side.
Why? If you want to install Vista or Windows 7 later, you can buy a second memory module and keep your 2GB module. That?s the easiest way. :)

And no, BIOS update is not necessary.

Based on the spec of U410 the maximum supported memory is "8GB max/ PC3-12800 1600MHz DDR3, non-parity,dual-channel capable, two 204-pin SO-DIMM sockets - * System automatically clocks down for processors with 1333MHz DDR3 memory controller". Based on this the maximum memory to be used in a system is dependent on the processor used. You may want to dig some more info on this issue, so head on to Intel's website and lookup your processor model number to determine the maximum memory that it is capable of addressing. And there are numerous questions similar to yours if you search their forum.

Hello, I consider buying a new notebook and T420 is a hot candidate for me. I'm not sure yet whether I would go for a Core i5 or i7 processor, however I'm sure I'd like to upgrade the RAM in the future and 16 GB would be very appreciated. I found out in the Intel specifications that (not only) the i5 2540 and i7 2640 that are available in the T420 configurations support up to 16 GB RAM, however in the T420 specifications concerning those processors I found that only 8 GB of RAM are supported. AFAIK the memory controller is integrated in the processor in these cases, so is there another factor that limits the size to 8 GB, or is it only an improper information in the T420 specs? I plan to keep the notebook for several years so the possibility of some reasonable memory upgrade would be a very welcome for me. Thanks in advance for any info on that.

Answer:T420 - maximum supported memory size?

Here is an unofficial answer.  I am not speaking on behalf of Lenovo. 
The T420 has 2 memory (DIMM) slots.  Technically the system can accept 16GB of memory (2x 8GB DIMMs).  I know this because the SMBIOS type 16 structure says so.  But I don't think 8GB DIMMs are available to buy yet, and even if they are, they are not available from Lenovo so at this time the max supported configuration today is 8GB.  I think it is safe to assume that, at some point in the future, 16GB will be supported.

Answer:Ideacentre700-24ISH - Maximum Supported Memory

Hi NF1  
Recommended maximum RAm for your pc is 16 GB ,  
Your Intel processor is capable to handle 32GB but just stay with the 16GB manufacturer recommendation for a tested value and optimum performance .  
RAM specifications: (Intel)  DDR4 4G/8G/12G/16G  , 2 SODIMM up to 16G DDR4    
You may check (page 29) the ones you have on the system ( matching the label on the sticker of the RAM )  for best dual channelling for another 8G,SODIMM,DDR4,2133MHZ  
Similar thread here .
Regarding Adobe Lightroom and Photoshop you may need to check with the specific developer of those software for further ways and techniques to make it work faster similar to batch processing and the likes. 
Additional concern is ram usage without opening any applications on Windows 10  .  It might be for a different topic if that is the case and different solutions may apply similar to this. 
Hope this answered your query.

The CPU specifications page from Intel for the 6200U/6500U both say 16 GB is no problem, and Crucial even has a 16GB dimm listed as "guaranteed compatible" for this model--I'm not sure, though, if this means it will work but only recognize 8 GB or if 16 GB is truly Ok. Is there any reason 16 GB could not be used? Perhaps some motherboard memory controller limitation? I would love to have some input on this before deciding on whether or not to purchase this laptop. Thanks!

I am trying to find out the maximum supported memory for Thinkpad W500, machine type 4063-A74. Lenovo web site provides conflicting information. According to, it is 4 GB. According to, it is 8 GB. Can anyone provide an authoritative answer before I spend hundreds of dollars for a memory upgrade that may not be supported? Thank you.

Answer:Thinkpad W500 maximum supported memory

it is 8 gig of ddr3 ram so far, but in the future maybe it will be 16 gig. The maximum ram figures offered by Lenovo and IBM are based on the current inproduction ram modules, so when the laptop was first released there were only 2 gigs module made, which then upgraded to 4 gigs of ram and hopefully 8 gigs modules (probably is going to cost a fair bit).

When I searched for Satellite Pro A100-196 on the internet , i came to a website ( which said that A100-196 contains one DDR II (533mhz) module and can place additional modules up to 4096 MB (which implies i can but 2gb ram modules each)

So I would like to know if anyone knows the definite MAX RAM (and type) i can place.


Answer:Maximum RAM and type for Satellite Pro A100

The Satellite Pro A100-196 seems to support the 667Mhz FSB!
So you could use also the 667Mhz memory modules (533Mhz is possible too).

I would recommend using the DDR2 200-PIN SODIMM modules; 667MHz (PC2-5300)

You can upgrade the memory max to 4GB. So it?s definitely possible to use a 2Gb in one slot!!!

The video RAM will be assigned automatically and you can?t change it. That means if the system needs more video RAM then it will be assigned more video RAM automatically.

But I don?t understand why you need more as 128MB video RAM. I think this is enough because the graphic chip isn?t designed for games.
There are better graphic cards on the market for games.

Reading the previous posts regarding maximum memory expansion for a Satellite Pro 4300 series laptop suggests that the maximum memory upgrade possible is 320MB made up of 64MB onboard plus two 128MB banks (128 128 64 = 320). I have asked Toshiba in the UK if the SP 4300 range will recognise 256MB PC100 memory modules but they couldn't give me a definitive answer one way or the other - only that they had tried up to 128MB modules successfully. However, the machine specs were written before 256MB modules were generally available and so I would like to ask the following questions of forum readers:

1. Has anyone actually tried a 256MB strip of PC100 memory in the memory banks of a SP 4300 series laptop? - If so what was the result?

2. Even if the maximum memory that can be recognised is still fixed at 320MB, could this be achieved by simply using one 256MB strip plus the 64MB onboard?

3. Has anyone actually tried putting in one or two 256MB memory modules in the memory banks and seeing what happens? Are they recognised?

Clearly this is an expensive experiment to try out so I'd sooner hear from other people who may have already explored these options rather than buy the memory myself only to find it is not recognised! I'm really interested in hearing from someone who has actually tried what I'm suggesting above (and either succeeded or failed) not from someone who has read the specs on the Toshiba website that says maximum memory is 320MB and then just quotes that...

I don?t understand why you want to use this 256 MB module. If you want to have the maximum performance, don?t complicate just use tested parts and enjoy the life.

I have Satellite A100-233 and I want to increase his memory. The question is, if on my motherboard can I put memory DDR2 with the speed of 667MHZ or I have use only 533 MHZ?


Answer:Satellite A100-233 - Which memory I need?


It?s depending on your chipset that you have ;)

If you only want to buy a second memory module I would be the same module as first one. So you know that his module is compatible with the notebook and normally only two identical modules should be used in the notebook to avoid incompatibility issues.

But as far as I know A100-233 can handle up to 667 MHz modules. If the first module runs with 533 MHz, the second module will also run on 533 MHz. That means the modules are downgrade compatible.

Answer:Satellite A100-294: Which memory should I buy


Hopefully I will receive some reward points from you because I think I can provide useful answers ;)
The laptop seems to support the DDR2 533MHz (PC2-4200) 200-PIN SODIMM modules.
You can use such modules from different manufacturers but in my opinion it?s better to buy a brand name module instead of no-name module due to the better performance

This site provides some compatible Kingston modules for Satellite A100-294

You can also mix the modules; I mean you could use 512+1024 or 1024+1024 or 512+512. All these options are possible

Hello guys.

I have got a problem. Ok basically I bought a whole new a while computer ago. It came with Vista Home edition 64bit Now on my old computer with xp I use to play a lot of games, and a game such as "Arma-Armed Assault". Well I found out that Arma can not be played with vista that is over 4 GB of ram. On here I have 8Gigs.

So I found a solution to this problem by going o my system config,Boot, Advanced options. There I had brought my maximum memory from 7936 which was what it came with to 3072 which it is at now. And I applied it, and restarted my comp, and wonderfully my Arma game worked.

Now that I am no longer playing Arma, and have Arma 2. I wanted to bring the maximum memory back up to 7936. But every time I do, and hit ok, it just goes back to 3072. And It can not go any higher.

So my questions, Is this a problem? and how can I bring it back up to the original 7936 memory(if i can).

Thank you.

Answer:System config Maximum memory

ok I found out the problem, I just had to bascially uncheck the "maximum memory box" and restart windows. My problem now is it says "0". When I click the box it goes up to 8192. I click Ok and apply. And then I reopen the advanced options and it says 0 again. Does anyone know how I can keep it on 8192?

Despite repeated emails they insist that these sticks are the 'replacement' for DDR2 PC2 4200 (which is now strongly indicated to me from my recent research as the correct memory - part # PA3411U -1M1G).

If I now buy 2 x 1 Gb - DDR2 PC2 4200 (from a different supplier of course) will I be doing the right thing ?????????? Assuming the new memory works, I'll be getting in touch with Crucial for some money (of course).

You can upgrade the RAM up to 2GB and usually you should use 2 x 1GB RAM 533Mhz.
In my case one big module was not recognized. I had to use 2 x 1GB RAM? but I don?t have this model.

I recommend using brand name modules; Kingston is good and provides good quality modules.
Different manufacturers provide cheaper modules but the performance and the quality is not really good.

I'm in the process of purchasing a Satellite A100-756 which has a 120GB HDD and 1GB memory.

I have seen what appears to be easy access hatches to both these areas. Is it easy to upgrade them and will this effect the warranty ?

I'm also trying to find out if the HDD with the laptop is SATA ? Can anyone help me with how to do this ?

Answer:Need advice about HDD and memory on Satellite A100


I am not 100% sure but all latest and newest Toshiba notebook models have SATA HDDs. To be honest to you I really don?t understood why HDD upgrade. A100 is newest model with really enough HDD capacity. Compare it with other notebook models and you will see that 120 GB is more than enough. RAM upgrade is always good.

Anyway the decision is yours and you can do what you want. Memory upgrade should not be problem because memory cover is at the bottom side. Sorry but I can not tell you where is the HDD placed but the fact is that probably keyboard must be removed.

I recommend you to contact your local dealer and clarify this with him. Memory upgrade should not be problem but for HDD upgrade it is necessary to disassemble the unit (not the whole) and it will definitely cancel the valid warranty.

Can someone please tell me the max memory speed for the Satellite Pro A100-828, i am wanting to upgrade to the maximum 4GB but am finding that some sites say the max speed is 533MHz whilst others say 667MHz. For example, the Toshiba site only lists 533MHz memory under the 'Compatible Options' yet other sites list 667MHz memory as compatible.

Thanks for your help.

Answer:Satellite Pro A100-828 Max Memory Speed


You should check what FSB (front side bus) would support.
Install the hardware diagnostic tool like Everest home edition and you should be able to find out this value.

If your chipset would support the 667Mhz then you could use such modules and the modules would run with 667Mhz too.

Answer:Re: Satellite A100 - using 512 MB + 1GB Memory togehter?


First of all you have to check if the notebook would support the 2GB RAM.
If the chipset would support the 2GB RAM then you can use the modules together:
one 1GB RAM and one 512MB RAM module.

But note; then RAM modules should support the same specifications to ensure that no error would be detected while booting.

By the way; more details about ?how much RAM is possible? should be mentioned in the user manual.

Answer:Satellite A100-440 - what memory that is compatible?


All modules which are compatible with Satellite A100 are compatible also with an Satellite A100-440? the 440 is just an sub model number and it?s not really important fro RAM upgrade.

You should be able to use the DDR2 667MHz (PC2-5300) 200-PIN SODIMM or the DDR2 533MHz (PC2-4200) 200-PIN SODIMM modules.

The speed of modules depends on the FSB (front side bus). If FSB supports max 533Mhz then your 667Mhz modules would run also at 533Mhz?

I would like to increase memory of my Satellite A100-036 (psaan), as 1 GB seems to be insufficient to run Vista. The problem is, I can't find out what my A100 would support. Now I have 512x2 Samsung DDR2 (533). I'm sure 1x2GB (DDR2, 533) would run OK, but what about some more? Say, 2x2GB?

First, I'm not sure whether 1x2GB chip would be supported by my A100. Any ideas?

Secondly, I've read somewhere that 4GB would be supported by my 945 Intel chipset, but there is no point in it unless I have a 64-bit OS, as 32-bit only support ca.3.2 GB. If that's true, would I be able to install 1GB + 2GB (3GB total) and use it efficiently? Are there any recommendations as to the combination of memory chips of different volumes (like 2 GB and 512MB)? May be it is better to have similar in volume?

And one more thing: not sure whether the chipset supports faster memory (higher than 553). And Can I combine 553 and smth faster?

Seems a lot of questions, but I hope someone could find some time and help me!

Thank you!!!

Answer:Satellite A100-036 memory increase


Well first of all, try to remove the current memory cards to look the model. For my A200, the memory cards are in the middle of the computer. You could go to the shop with one of them and buy one that's about the same model or even bring your laptop directly to the shop and try them there. The people at the shop will probably be able to determine the right card for your computer.

Answer:Satellite A100 memory upgrade


the machine can be upgraded to a maximum of 4GB of main memory, and if it´s worthy can by no one be answered, but only by yourself.

Do you really need it? I think the best would be that you upgrade to 2GB since you´re not a graphics designer which has larger pictures (which can be some gigabytes tall :) ).

As a normal user under vista/XP you only need 2GB. You won´t even recognize the jump from 1GB to 2GB of RAM or more.

Regarding the modules FSB frequency: it doesn´t matter which frequency you use, you really won´t gain any performance when using the 667mhz modules, so just obtain a fine pair of 2x2GB sticks with 533Mhz and just enjoy the "speed".

Here´s a little explanation for S0-DIMM:

As far as I know the FSB is able to handle 667Mhz modules.
You can use lower modules (533Mhz) without any problems but modules with higher Mhz will not run with full speed due to the limited FSB.

So I don?t recommend buying 800Mhz modules. Firstly they are not supported and secondly it?s waste of money!

Answer:Satellite A100-692 PSAA9E: What is the max memory

Besides the internt pages I think you really can only use a maximum of 2GB, as the biggest official memory module is only a 1GB one.
Anyway, more than 4GB are useless if you dont't use a 64Bit operating system.

I would suggest that you use 2x1024GB 533mhz modules.

Mixture of 533 and 677 might work but wouldn't risk any incompatibility issues.

I thought the maximum RAM that could be recognized in the SP4200/4300 series of machines was the 64 MB onboard plus a maximum of 2 X 128 MB strips in the two expansion slots making a total of 320 MB.

However, I have come across a posting from someone who claims to have managed to get 448 MB recognized (64MB onboard, 256MB in one slot and 128MB in another slot) in a SP4270. This seems to go against what was supposed to be the maximum spec of 320 MB made up of 64MB onboard plus 2 X 128MB in the expansion slots.

The accepted view was that 128 MB memory strips was the maximum that could be recognized in each slot. However, this contributor appears to have discovered that this is not the case.

Have any other contributors had any luck with 256MB memory modules being used/recognized by the SP4200/4300 machines? The poster suggested that the machine could cope with one 256MB module and one 128MB module.

Any comments from anyone who might have tried this or variations on this? What about two 256MB modules? - Anyone tried it?

I'd like to add some memory to my laptop and been trying a couple that do work but I am getting some bugs because that seem to be related to the fact that I put pc5300 memory rather than pc4200 memory... The odd thing is that it works fine and only bugs when playing music and flash movies!

Does anyone know with certainty what type of memory can I use ... what is actxually the most important , the frquency (533) or the pc4200 ... how can I know what memory i can buy and be sure it will work, even if I have to throw the actual one if there are compatibility problems?

Many thanks for any guidance!

Hello all,

Is there any body knows how to adjust the video card memory of Toshiba Satellite A100-811 laptop?
The physical memory of my laptop is 512MB I want to share to my video card of about 128MB, nomatter if 384 will be left in my physical memory.

Your imediate response is highly appreciated.

Thanks in advance

Answer:How to Adjust the Video Memory on Satellite A100-811


the Satellite A100 supports an Intel 945GM 8MB-128MB shared memory graphic card, thats right. But
afaik it?s not possible to assign this shared memory manually, it happens automatically.

If the running application needs more graphic card memory then the OS will increases this value automatically.

It seems this notebook was delivered with 512MB memory. In my opinion you have to upgrade the memory to 1024MB if you want to use the full 128MB of shared memory.

for start.. i own a satellite a100-192...
i'm thinking of upgrading my ram and i know that the type of ram inside my notebook is ddr2 pc533 so-dimm...

But I cannot find what brand of ram is it shipped with my kind of notebook?

Answer:Satellite A100-192: what is a brand of my memory modules

Well, I assume the Toshiba delivers the own notebooks with the Toshiba memory modules.
It seems these modules are compatible:
DDR2-533 256MB (PA3389U-2M25)
DDR2-533 512MB (PA3412U-2M51)
DDR2-533 1GB (PA3411U-2M1G)

Also the Kingston modules support a great performance and could be used.

I'd like to buy A100-906 notebook. It has 1024Mb DDR2 533mGz memory but I want to rise DDR2 memory upto 2Gb. So my question is:
Are these 1024Mb the single DDR2 1024Mb plate in one DDR2 slot and the second DDR2 slot is empty or they are the couple of 512Mb DDR2 plates and both DDR2 slots are occupied?


Answer:Question about DDR2 memory on Satellite A100-906


In my knowledge the notebook was delivered only with one 1024MB module and the second bank is free.
So it should be no problem with a memory upgrade to 2048MB

Hi friend,

man thats easy to solve. You must only read this [article from|] and this [Toshiba Support Document|].

Everything will be clarified and you will be enlighted about the fact that the system itself without the operating system needs also his amount of RAM to work properly.

Hi all,

i have a question.... i can change the quantity of memory available for the video card?
Now the pc with Vista home premium have only 64mb dedicated for the video card and 271mb of system memory available and 0 of system memory used.
It's possibile change by software the setting of video memory?


Answer:Satellite A100-750: How to increase the graphic memory


Are you sure your notebook graphic card supports a shared memory?
As far as I know the A100-750 was delivered with a nVIDIA GeForce FX Go7300 and this card supports own 64MB video memory. This is not shared memory and therefore you cannot increases this graphic card memory to a higher value.

In this case the graphic card uses own memory and the notebook do not need to share the main memory with graphic card.

The graphic card shares the memory but this is controlled automatically by an graphic card driver.
You cannot assign or add the memory manually.

I've just bought a 1 Gb RAM memory to upgrade my Satellite from 2*512 to 1*1024 + 1*512.
The memory brand is Crucial.

Wherever I put my memory (1 Gb in slot 1, 512 Mb in slot 2 or the opposite), my computer only recognize 1 Gb.

Some ideas about this concern ?
Do I have to put the same size of memory in each slot, may be ?

Thx in advance for your help.



Answer:Satellite A100-551 recognizes only 1GB RAM after memory upgrade

Do you run in Windows Vista?
Some days ago I put an extra 1GB in my mom's laptop and it showed only 800 MB instead of 1.5GB of RAM. It seems that Vista is taking some memory for itself (that's what I've been told).

If that is not the problem, are you sure you bought RAM memory compatible with your laptop? Does it use DDRI or DDRII? I am asking for you didn't write anything about the memory except for the manufacturer.

I recently bought 2x2Gb modules for my A100-828. However, i cant get any memory module to fit in the second expansion slot. I have tried both the new modules in it as well as the old 512Mb module that was originally in the laptop. The new memory is definately compatible as both new modules work in the first expansion slot.

The memory doesn't seem to fit properly in the second slot (i have put it in the right way ;-p ) it wont push all the way in.

Anybody have any ideas what the problem is?

Thanks for your help.

Answer:Satellite A100-828 - New memory module wont fit


I don?t know why the module cannot fit in the second slot.
Both slots are completely the same and support also the same standard.

I think you used simply not compatible modules or you tried to insert the modules in wrong way
As far as I know you need the DDR2 667MHz ( *PC2-5300* ) 200-PIN SODIMM module.

What module do you use?

Hello all,

I want to upgrade RAM on my Satellite A100-181, because 512Mo is a bit limited...
I ordered a noname 1Go dimm one month ago, put it in, with the 512dimm. As a result, we have only 1Go recognised, and the laptop won't boot if the 512 module is not mounted.

I thought it was a bad memory module, and ordered a 2Go kit from crucial, memory modules that come paired, and guaranteed by Crucial to be compliant with the toshiba A100-181.
Result is the same: with the 2dimms inserted, the PC won't boot: it just turn on and off, and again... With 1 dimm only, it won't boot except if the original 512 module is joined to it... And one time again, only 1Go is recognised (915456Ko in the bios, but I suppose that video reserved memory is not counted here)

Does anyone has ever heard an issue / solution about this ?

Thanks a lot.

Answer:Memory issue while upgrading my Satellite A100-181

This is typical behaviour when you use non-compatible modules.
Your notebook can handle with 2GB max and compatible 1GB Ram is DDR2-400/533 1GB (PA3411U-1M1G). Use this part number to order compatible module.

You can also buy /order Kingston module. Kingston offers high quality products and using them you will not have such problems.

The "Value" RAM Modules use a lot of cheap chips utilizing multiple banks/channels, which can cause compatibility problems with some Chipsets/CPU's.

and the memory cover comes off without too much trouble. Make sure the screw is fully undone, and then gently lever off the cover using a screwdriver or knife under the small tab.The cover has two smaller tabs on the sides, and these click into (and out of) slots.Just take it gently but firmly, and I'm sure the cover will come off.

> However when the original 512Mb sodimm is put back into one of the slots - it doesn't matter which - either of the kvr etc sodimms work giving a total of 1.5Gb of ram.

Cannot believe that! As far as I know this notebook was delivered only with one 512MB DDR2 533MHz (PC2-4200) 200-PIN SODIMM module.
Of course you can upgrade the memory up to 2GB using two 1024MB modules.

The compatible memory can you find here:

> Also is it poss. to upgrade cpu ie is cpu socketed. I've already upgraded many a laptop cpu when they had socketed cpus, so I'm aware of the problems involved
Well, what to say, the CPU is socked? you can find out it easily using an hardware diagnostic program like ?Everest?. It would provide many useful information about your notebooks hardware.

But to be honest, I?m very skeptical about CPU upgrade on the notebooks.
If you have already changed several CPUs on the notebooks then you should know that this is not very easy and more tricky like the CPU upgrade on the desktop PCs.

I have a Satellite Pro A100-830 and I bought the maximum allowed memory for it which is 2x2Gb which in my world totals 4Gb. When I put the dimms in on their own in either slot, the BIOS reports 2Gb. Well done bios! When I put them both in together, I only see 3Gb in the bios!

I did find this link on the Crucial website.

It would suggest that page files, devices etc take up memory on you system at start up, before the OS kicks in I assume. If you have not got the maximum memory installed, you should see the total memory. If you have got the maximum memory installed then you will not see the memory in use by the page files etc. Why would this be? Why would you see 2Gb if you only have 2Gb but then see only 3Gb if you have 4Gb because of the system!

Can anyone shed any light on this subject and either qualify or reject the information in this link. Do I need to replace the memory and/or the pc?



Answer:Satellite Pro A100-830 with 4Gb of memory but BIOS tells me I only have 3Gb

This not a BIOS problem but a Windows issue.
I found this info:
Windows XP Professional 32-bit is limited to 4GB of address space. If you have 4GB of RAM installed, it will not show 4GB within Windows. What you'll probably get is the size of your pagefile subtracted from the 4GB.

Some of this address space is reserved for hardware and the OS... so you'll never have access to the full 4GB anyway. If you want to access 4GB+ of RAM... your best solution is to pick up XP Pro 64-bit... but that will only work if your P4 CPU has EMT64. (64bit)
You can also try enabling DEP if it isn't already enabled... this will also enable PAE which may give you access to all 4GB

So finally a answer:
> Do I need to replace the memory and/or the pc
-> No, everything is ok... you don't need to change teh hardware

The original user manual (1997) for this machine says 2-Gigs is the maximum memory capacity for this 2-slot machine, but nowadays compatible 2-Gig chips are available.

Can I upgrade to 4 Gigs? (or is there some other aspect of this machine that limits Memory to 2-Gigs? )

Answer:Question about memory expansion Satellite A100 PSAA9E


The memory upgrade depends on the chipset!
If the chipset would support only 2GB then you could use max 2GB.

I think if the user manual said that 2GB are max which is possible then this will be right?

Of course you can check this as well.
Check your Intel chipset and then search on the Intel website for more details and properties of this chipset.
