That's strange, I guess different chipsets 'chew' up different amounts of memory OR you have your DVT(?) (video-card memory/aperature) set to 256MB? I have mine set to 128MB, in top:

Mem: 8039576k total, 6187304k used, 1852272k free, 696k buffers
Me:
Mem: 7416672k total, 378988k used, 7037684k free, 13592k buffers

What type of memory are you using
2x Kingston KVR667D2N5K2/4G
and what is your DVT set to?
GigaByte's BIOS config options of the onboard graphics controller are
very limited compared to those on your Intel motherboard.

I can only choose the graphics buffer size, between
"1MB+1~2MB for GTT" or "8MB+1~2MB for GTT".
I chose the latter. The POST says 9MB are taken for video.

Not that it matters much, as the current i810/intel xorg driver does
not yet support the GMA3100, so I'm using the vesa driver.

Thanks,
Pim


I use the exact same memory model. So it must be the difference in BIOS MTRR/E820 memory mappings.
