I've noticed a strange quirk about the video on my MA78GPM... I have 128mb Sideport and also have the BIOS set to use 256mb shared memory. This is reflected accurately in the My Computer/Properties window, 1.75GB ram showing to windows, and I have 2gb.

But the ATI properties are showing that I have 700mb video memory. Now, last I checked, 128 + 256 was not equal to 700. This has remained the same across a couple different driver versions.

It's not a big deal, everything works fine, I'm just curious if anybody else has noticed this behavior?
