Hi,

I recently installed an extra 2 gig ram module on the motherboard.  I'm running Windows Vista home premium.
The funny thing however is that when i go into configuration screen, system it seems vista only sees 3 gig or ram while i have two modules of 2 gig = 4 gig.

Is  there a way i can force vista to see the 4 gig.?.

Do you have 32 bit versio of Vista? The 32bit version can not see the full 4 giga bytes of ram due the 32bit limitations (The maximum amount is something like 3,2 gigas if I remember correctly). Only the 64-bit version can see 4+ gigs. I hope this helps.

Installing Service Pack 1 will make Vista see 4GB, but it doesn't mean Vista will be able to use it. 4GB is what you're going to see in the welcome screen (if you have it activated).

If you then run MSINFO32.exe you will see:

Total physical memory,
Available physical memory,
Total virtual memory,
Available virtual memory.

Yup, 32 bit version.

update :

Going into bios, noticed that motherboard only recognises 3 gig.
Went to manufacturer site, downloaded and installed a bios upgrade, the same... only 3 gigs are seen in bios and windows vista.

64 bit Vista will recognize 4 GB of memory
