Tried to upgrade to 3gigs of RAM, XP won't recognize

Thu Sep 18, 2008 7:20 am

I've recently upgraded my video card from a vanilla 6800 to an 8800GT 512mb, as well as going from 2GB of RAM to 3GB of RAM.
The BIOS recognized a new ram amount, and sees it as 3GB.

I am well aware of the 4GB limit on addressable memory, however I wouldn't expect an older system to reserve so much (1.75GB reserved or used elsewhere).

This is my hardware:
CPU Type Intel Pentium 4 630, 3000 MHz
Motherboard Name Dell Dimension 8400
Motherboard Chipset Intel Alderwood i925XE
System Memory 2304 MB (DDR2-533 DDR2 SDRAM) (BIOS reports the full 3GB)
BIOS Type Phoenix (01/10/05)
Video Adapter NVIDIA GeForce 8800 GT (512 MB)

Two IDE optical drives, 1 150GB sata drive, 1 PCI sound card, using on board network card and that's it.

I tried updating my BIOS and I disabled onboard sound, but no changes.
I do not have an option to disable the onboard video, at all, unless I'm missing something.

My DIMM setup is:
I have a 512 stick in DIMM 1 and 2, and a 1 gig stick in 3 and 4.

And I did confirm that the board supports up to 4GB of memory.
This is the manual for my system:

Is there anything else I can try? Any way to see exactly what addressable memory is being used and by what? To change those settings? Any way to force a disable of onboard video if the BIOS does not have the option?

Try SPD tab in CPUZ to verify if all the sticks are recognized in Windows.

I will try that once I get home. However, I do have EVEREST Home Edition and they were all recognized there.

Looks like you are not the only one.
The Model M is not for the faint of heart. You either like them or hate them.

Seems like that guy was at least able to get 2.5GB, at this point I'd be happy with that much instead of 2.25GB.
Hopefully Newegg will let me return this as I paid for a 2 gig kit to get 256MB of ram.
Is there another way to force my onboard graphics to be disabled other than the BIOS? I suspect that would clear up some additional memory.
