Is this a sign that I OC'ed my video card too much?

At another forum I noticed someone else with the same problem.

when I OC the core or the memory too far on my video card 3DMark 2001 SE either crashes to the desktop or restarts my computer. If I lower it down to the previous settings it will run 3DMark fine. It seems the farthest I can go is 290 core and 550 memory. If I go upto 295, or even 293 3DMark crashes to desktop or restarts my PC. Same thing with the memory if I go upto 555. This is with a GF4 Ti4200 128mb.

So is 3DMark crashing like that a sign that my video card has reached its limits? I see no visual artifacts, it'll either restart or crash sometime on the nature test, or even as far into the benchmark as the advanced pixel shader.

sounds to me like its overheating
usually a sign of going to far is artifacting and tearing

hmmm, I have an 80mm side intake blowing right at it.....

I checked and the video card fan seems to be running at full speed, plus the 80mm fan blowing right at it from the side. That seems to be enough cooling for an OC that small. My CPU runs at 36 idle and 44 load.

Generally, if you are experiencing lockups and crashes, the core speed is set too high. You generally only experience artifacts when the memory is set too high. Drop the core speed down and see if you can increase the memory speed anymore.
