I have gigabyte 7nf-rz motherboard. It is nforce2 based. Problem is that chipset or particular board or bios or whatever... is unstable when AGP rate is set to x8. During heavy use (3d or even flash/mplayer video play) it tends to lock system hard. So hard, that even played sound is looped inside soundcard buffers. This problem is persistent over many windows xp installations, various linux distros, many nvidia blob drivers. My card is nv7600gs, but even amd radeon 9200 suffer same problem. Solution is simple: set agp to x4 - problem solved 100%. Nvidia blob allowed me to do it. Now I'm using fedora13 with nouveau. Is there any way to set agp rate to x4? My setup: xorg-x11-drv-nouveau-0.0.16-6.20100423git13c1043.fc13.i686 libdrm-2.4.20-1.fc13.i686 kernel-PAE-2.6.33.5-112.fc13.i686 Yes, this problem is a blocker for me to became nouveau user in long term. Have nice day.
