Re: 6800U PCIe Issues - Summary
I also had in-game freezes in UT2004, but these have been below one
second and disapeared after setting "VARSize" in UT2004.ini to "0"
(this defines the size of AGP cache in main memory which doesn't
make sence on PCIe).
My system (A8N-SLI, Athlon64 3500+, Galaxy 6800GT, 470W PSU, Fedora
Core3) works rock stable - never crashed.
From my ten years of linux experience, sudden reboots are typically
hardware issues. I suggest trying out if using another PSU or graphic
card makes a difference. Maybe the CPU heat sink is not perfectly
mounted - does the machine also crash during compilation or other
CPU demanding processes?
