Can loop Prime95 24/7, but can't loop 3DMark2001 for extended period..what gives?

I just thought of this, b/c I was gonna try to OC my videocard tonight, but now I dunno 'bout that.

I'm running a 1GHz TBird @1.1GHz (10.5 x 105) on an Abit KT7R. I can run Prime95 24/7 and the CPU gets warm, but not hot. No lockups. I can run Prime95 in the background and burn CD's, surf, email, no prob.

But if I try to loop 3DMark2001, it crashes. Now, I've run like 10 loops of it, just to see how hot the case would get, that's not what I'm talking about. I mean like if I set it to loop, go to sleep, in the morning, it's either crashed to desktop at 800 x 600 @ 60Hz (goes back to 1152 x 864 @100 on reboot, no prob) or it's hard-locked.

My system is rock stable under normal usage. No BSOD's/screen anamolies under a regular 3DMark benchmark, games or if I loop it like, 10 times or so. Any ideas?

3d mark is a piece of garbage cuz I own a kyro2.

Play games. See if it crashes then. If not, you are good to go.

Games are fine. I had a massive fit of online UT last night. 3 hours straight, no breaks, turbo instagib....immediately after shutting down UT I checked my temps. 45CPU/26System. Same temps as Prime95 gives me. Interestingly enough, DeusEX, which is a "really slow" game, gets the CPU to 49 sometimes 50C. Weird. But NO visual probs w/games.

Prime95 wont make it get as hot as RC5

yeah, 3dmark seems to be pretty usless as stablity bechmark. I've run over 24 hours of UT/SETI and UT/Sandra over 20 with no problem. 3dmark though only goes for a few hours before going back to the desktop. As for overclocking your graphics card I'd try UT, look for odd texture errors. I'd also run a program called Artifact Tester, its seems to be very accurate... at lest in my use.

Nice linky, Operandi. I'll check it out. Thank you.
