Satellite A100-011 (PSAARE) RAM upgrade issue

[chriszg]

I have Satellite A100-011 (PSAARE) and i have just upgraded memory RAM to 4 GB with 2x2GB Kingston (KTT533D2/2G).
BIOS can see all my 4GB installed,so my Windows (x64) but my Task Manager shows me 3069 MB!!!
How is this possible?Is there any way to fix that?My BIOS version is 6.00.

Thank you!

Hi!

Are you sure that you have a 64bit version from Windows XP?
I ask this because the Toshiba website does not offer drivers for XP 64bit.

If you have really a 64bit OS make sure that you have installed all Service Packs and Hotfixes from Microsoft.

And install a program like Everest and look how much RAM this program shows.

Bye

Only a 64bit OS can recognize 4GB RAM and as Lars_3 said are you sure that you have such OS?

To download Everest use Google or you use CPU-Z.
With these tools you can see how much RAM Windows recognize.

Thank you very much for your replies.

I had Windows Vista x64 before and now Windows 7 Beta x64.
I don't have any problems with my drivers,both editions recognized them and have all the updates installed normally.
I tried Everest and CPU-Z as you recommended.
Everest tells me that i have 3069MB (just like Task Manager) and CPU-Z tells me that i have 4096MB!!! ?:|

The Vista recognized 4GB after SP1 update…Please check if all MS patches has been installed.

PS: Seems Everest cannot read it correctly….
