What's the best miner to test the stability of a core overclock? And how to identify instability?

I guess miners don't do any error checking, since I am at 822 Mhz core on a Radeon 4670 and I get no errors while mining. But any game crashes immediately at those clocks.

Some miners do check the results before submitting them to a pool or bitcoin client (DiabloMiner does for sure).

Hm not sure how good miners are when it comes to test the stability of a sytem.

I can recommend some stress test tools:
Super Pi (CPU)
toast (CPU)
FurMark (GPU)
PCMark (whole system benchmark)

Those test stability for common workloads. For mining only the GPU is stressed, and not even all of it, ROPs and TMUs are idling. That's why I asked what miner gave error reports.

Phoenix do it. I ran it few days ago and shows message about hardware unstability, when I pushed gpu voltage too low. For harder stress test use AGRESSION above 7.  Smiley

Moving on is a simple thing,
what it leaves behind is hard...

Since I often buy cards from eBay and am tempted to buy one of those "defective" cards, is there a possibility of creating a small utility that stress tests the OpenCL capabilities of a card so that I can send it to the seller and let him check if the card is working before buying?
