Hi there,
I have a dual-opteron with 8GB of ramm installed (8x1GB dimms) on a
Tyan K8W (S2885).
But linux only uses 7.3 Gb...
Linux on boot detects correctly the available 8Gb:
[snip]
agpgart: Maximum main memory to use for agp memory: 7956M
[snip]
Having 700MB of fast ram being unusable isn't very to my taste...
I agree with other posts re flashing bios and tweaking memory settings.
Also, try disabling features you don't need in your bios. Can you turn
AGP off? Try setting things to manual instead of auto..
Please read this thread, as it may also apply to you:

On a side note, when using 4 x sticks of ram per CPU on your mainboard
do you still get DUAL DDR?
Or is it reduced back to single DDR when using more than 2 sticks?
cheers,
