AGP Apperture size setting

[Abomination]

I've got a 128mb FX5900XT graphics card. Should the apperture size in the mobo bios be set to 128mb or can you get a little performance tweak by setting it to 256mb or will increasing the size actually degrade the performance?

Thanks for your help

you should just set the BIOS aperature to 128 MB, since your card only has...128 MB...no performance increase if you set it higher...since aperature is just an opening and your Video card won't even go at 256.

Being a fellow 5900XT owner (I have almost the same setup, too), I recommend setting the AGP aperture size to 128MB.
However, some recent games (like Battlefield 2) may be somewhat faster with a 256MB aperture size. I've never experienced any boost in speed, but it might help you.

Rule of thumb

256MB DDR = 128
128MB DDR = 64
64MD DDR = 32

Those are the settings you should make in you BIOS for your AGP Video Card.

apeture size

I used to own the same card, and almost the same mobo.
i always set the apeture size to however much ram is on the video card. never had any problems like that. that should keep you in the safe zone.

good luck
