My BIOS doesn't have an option to change video RAM.
I pulled out 2 GB of RAM so I only have 2 GB in the computer. But it's showing up as 2048 MB, not 1536 MB. So the problem only happens when I'm trying to use 4 GB.
So
exactly 0 MB of my RAM is used as video RAM when I have only 2 GB installed.

I hope that's the case. You can understand if I'm a little wary, though.

Went to the gigabyte's site, flashed the BIOS, and bang... I've got my 4GB all nice and shiny.
(I don't recommend flashing BIOS unless it fixes stuff you are actually having problem with since many things can go wrong. If you are desperate enough, give it a try.)
That sounds promising. I may try it.

As you probably know yourself, there's bunch of stuff to configure, might be there's some for RAM speed, etc that you missed or require manual setup.
The two things that I most wanted to change were RAM speed and video settings, but my BIOS doesn't seem to have options for either! It's strange, because I'm used to seeing both. Maybe the RAM speed is there and I just missed it because it was listed as a multiplier rather than a speed. Hmm...

OK, I'll check that. I had a lot of trouble getting this computer to work -- the original motherboard never worked but conducted enough voltage that it fried the 3 (!) processors that were installed (one at a time, naturally -- two by me and the third by a Microcenter tech), so I've read the manual rather closely. But I haven't consulted it in the months since.
