Hi,
I have an ECS GF7050vt-m motherboard. It says it can handle ddr2 800mhz 2
gigs each slot total 4 gigs. I installed 2 2gig Kingston ddr2 800 mhz sticks
in the pc and during boot it reads 800mhz 4 gigs, but in Windows it says 3
gigs. Is there a patch or a setting to correct this? I have no errors or
problems but want to ensure it acknowledges all 4 gigs.
Thanks,
John
 
There is a limit of 4 gig address space, your other hardware is
occupying the remaining 1 gig of address space. The reason you have no
errors or problems is because it is working properly and as designed.

See PDF page 38 "Advanced Chipset Setup" at the top of the page.

Experiment with "Memory Remap Feature". Try with it disabled.

For some idea of what memory remap does, see PDF page 14 here.
The BIOS "Top Of Memory Under 4GB" displayed value, might refer
to the equivalent of TOLM register. It might read 3.00GB with
remap enabled, and a slightly higher number with remap disabled.

In round numbers XP can only address 4GB.
Your video card has XXXMB of ram on the card so
that limits XP to 4GB minus the cards XXXMB of memory.

In addition other hardware also takes away additional amounts of memory
(usually a small when compared to the video card)
and the remaining memory (address space) is available for
Windows XP and your applications.

So that 4th GB of ram you installed or will install goes unused.

A link to the white paper titled "Gaming Performance Analysis" by Corsair
Memory Inc. provides a good clear explanation of how a video card effects
the amount of available memory in your PC.

Thanks to all,
IT makes sense in a Microsoft kind of way, lol. The "white paper" really
explained it. Thanks again.
