AGP aperature

[oymd]

what's the right size of the AGP aperature in relation to system RAM and Video card ram
for example:
128MB ram.....and an ATIRadeon64MBDDR...on a P41,5GHZ

It should be half your system RAM, so in your case 64. I have 512 MB of RAM, but when I set my aperature to 256, I got random crashes, so now it's at 128.

I've always set mine to the same number as the video card's ram. Is there any advantage to setting it higher?


If I don't get my 90THz AMD Quadraplex system soon, I'm afraid I may just combust right here.

Setting it to your VC's RAM means that you can't use anymore memory than that.

Setting it higher means you can use that much more memory, but it will use conventional as oppsed to VRAM

Mine is set to the same value as the ram. It wont go any higher. I'v had no probs from this.

According to Rojak's bios op guide it should be 64MB or 128MB.

Everything I've ever seen concerning this value is that it should be half of your system memory. However, many motherboards had some sort of problem with the 256 setting, and so the recomendation is generally if you have anything over 256 megs of memory, you should set it to 128 megs.

BTW, this setting is the amount of main memory that the system prealloacates for use with AGP texture storage. I do not know if this means 128 megs of memory is "locked" at system start time and kept from use with other programs, but I suspect that it is.

so...with my hardware....all u guys suggest is 64MB aperature??

I am currently running a Nvidia Geforce2 Ti with 64 MB with 192 MB of ram. I recently changed my AGP aperture from 64MG to 256 MB, this resulted in an enormous increase in my framerates and 3D mark scores...it tripled, even more for certain applications. So, I guess the best advice for this would be to try it out. Use a different setting and test it. You should stumble upon a stable setting that also performs well.
