Hey friends, I'm not 100% sure I understand what the agp aperture size in BIOS is. I have one of the V5 5500s from Anthony with 128mb VRAM (switchable to 64mb). I have 512mb RAM on the system itself. Help appreciated, thanks!

I doubt it would make much difference IMHO. I would do 64 or 128mb but probably just leave as 64mb.

Doesn't matter for Voodoo 5.

I must be some kind of standard: the anonymous gangbanger of the 21st century.

Agp aperture size reserves some addresses in systems memory, that a video card can use to store data if its vram is full. But the card has to support it, agp direct memory? Something like that. And Voodoo 5 doesnt support this So you are fine disabling it or setting it to its lowest setting.

If you use other cards in the system, theres no harm in having it set.
