Is there a program out there to test GPU stability by torturing it? Something similar to Prime95, Orthos, etc?

ATI tool artifact test and graphic benchmarks (Crysis, etc.)

For sure better cooling helps overclock, before I flashed my X1900XT to an XTX Toxic the max stable overclock I could get was 648Mhz @ 89c load, I slapped on the AC Accelero X2 at max fan speed and I can now get 675Mhz @ 76c load with a .0025v increase. While I was using the stock cooler add volts did absolutely nothing but add heat.

If heat is the primary limiting factor, then lowering temps will improve your OC. If it's not, lowering temps probably won't do much of anything (barring an extreme drop).

Most 2900s on stock cooling are temperature limited to a decent degree.

That seems more like physics.

Anyway, the vibrations of atoms/molecules and whatnot are not the direct cause of instability.

With all due respect to those who have already answered, nobody can really tell you an answer without first knowing what your temps are at your highest stable overclock.

If you overclock your card to its highest stable point and your gpu temps are still within the thermal specs for that gpu (while under a load), then temperature is not holding back your card at all.

So before answering your question with anything more than a wild ass guess, these all knowing people should have asked what your gpu temps were.

If you are overclocking, read this please.... http://www.overclock.net/intel-memor...rclocking.html

Which is why I asked if there was a program out there to test my GPU at full load so I can see what temp my card is at. I know there is the artifact tool in Ati Tool but I seriously doubt the little graphis running during the test is really stressing my GPU to its limit. And running game benchmarks like Crysis run at full screen so I can't get an acurate temp reading.

Liquid Nitrogen??? LOL, not going for any records here.

Well, explain to me why my 8800gts can reach a higher stable overclock at <60C than I can at a higher temp. The thermal limit of the GPU is much higher than that, but the lower tremps yields more stability.

But I do think that my question can be answered. It was a very general question.
