I've seen similar problems posted here but wanted to state this for the record. I've been having "freezes", "sudden abends" and every now and then a complete reboot. I downloaded MadOnion's Video200 benchmarking tool and it ALWAYS freezes during the data transfer test (local <=> non-local AGP). The 3DMark2000 works pretty well, it only occationally locks up (once every 20 tries). I'm hoping that there is some sort of remedy.
Please feel free to make any suggestions or comments. I'm just about out of ideas. I was hoping the MadOnion test points to a specific issue.
Here are some specs and solutions I have tried:
MicroStar 6167 ATXIR1 (Award BIOS V1.5) with 2x AGP (See Notes Below)
Athlon 700 Processor
Guillemot 3D Prophet v2.10.24.00 (w/Geforce 256)
FastTrack Ultra66 EIDE Controller
Creative Sound Live Drive
NVidia Drivers 368W9X (See Notes Below)
AMD Miniport Drivers V445 (See Notes Below)
Applied a registry setting that seems to have help somewhat, but not a complete fix.([HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\System]
I have set the AGP aperture Size to just about everything (256MB to 4MB) to no apparent avail.
I have tried the Guillemot Drivers (even the latest version just released) and they make the problem worse. Nvidia's drivers (for GeForce 256) are working best for me.
I have played with most of the OpenGL and Direct3D settings. I can't find a consistent correlation between the settings and the problem.
