Hello,

I'm in the process of building a new box, but for the time-being, I bought a little upgrade for my current old box, in hopes it would help my gaming.

It consists of:

nForce 680i
(just bought) 4 gb DDR2 800
Intel Core 2 Duo 6600 2.4 ghz
nVidia Geforce 8800 GTS

My question is, are there any downloads to help Windows XP Pro SP2 (32-bit) identify more than 2.75 gbs of RAM? I could have sworn, on these forums I've read that 32 bit OSes can use up to 3.75gb. I'd hate to think I just wasted $92 on RAM, simply for the extra 750 mb.

Thanks in advance,

3.25Gb is the max alocated ram for XP. Are all 4 modules the same or did you mix?

Have you updated to the latest Bios? Last time I saw a similar issue, it was fixed by downloading SP3 (update).

Actually, 4GB is the maximum, but it will always be a little lower than that. 3.75 is very possible. It all depends on what hardware you have and how well the bios optimizes the address space below 4G.

It's 2 sticks, 2gb each.

To be honest, I wouldn't know where to find an updated bios version for this dated nForce motherboard. If the OS doesn't ID it, it's not being used correct?

I'll check the Bios momentarily and verify what amount of memory is ID'd.

Edit: I just ordered the OEM version of Windows 7 64 Home Edition, so I doubt this will be much of a problem later on.

While it's shipping though, I'd love it if I could scale up the Dragon Age Origins speed.

If the MB is indeed identifying the 4gb of RAM, then should I simply download Windows SP3 and hope that allows for more memory to be used?

Minor Hijack. Apparently, I had 2 1gb sticks of DDR2 800 before upgrading.

They're Corsair, the new RAM is PNY. Can I have 2, 2 gb sticks and 2, 1 gb sticks totalling 6 gb when I install Windows 7 (64)?

(All RAM sticks are DDR2 800, so I'm thinking this should work)
