What? 'since amount of RAM' has nothing to do with AGP aperature. The aperature should be the same as the amount of AGP shared RAM used for the screen-card on-board graphics. This is normally set by the BIOS but can be reset if the BIOS doesn't 'understand' your screen card. So, unless you have 256 MB on your screen board, typically 32 MB for high-resolution true-color boards, you will be disabling PCI hardware hand-shaking for a lot of addresses above your screen board. This can make DRAM-controler, controlled RAM accesses interfere. Cheers, Dick Johnson Penguin : Linux version 2.4.18 on an i686 machine (797.90 BogoMips).
