Thanks for the reply. I couldn't find a memory size listing in the BIOS,
but Memtest shows 3839M. BTW, it's a GIGABYTE GA-MA78G-DS3H motherboard
with on-board video. & in fact, in the BIOS I did allocate 256MB of ram
to video. If there was that amount of memory missing, I guess I'd have
thought, OK, that's where the missing ram is being used. But I can't
figure out the discrepancy. The ram is OCZ Reaper HPC Edition, Model
OCZ2RPR800C44GK:

(hmm... before getting this ram I thought I read in the customer reviews
where a few Linux people were using it. I don't see anything now, but
that may or may not matter.)
Anything else I can try?
