Stress Testing Software

[Greeny1994]

Which is the best free stress testing software to test the stability of a graphics card overclock?
I have used MSI Kombustor on Xtreme burn in which seemed to do the trick, but as soon as I launched Dirt 3 the drivers crashed.
Dropping the memory clock allowed me to play Dirt 3 so I have given up using it.
Any suggestions would be welcome

Thanks

I use Heaven. It is particular good at spotting when an OC on the memory is too much and error checking is kicking in (i.e. the score drops when with higher memory clock). It tests the GPU too of course!

Heaven for testing when your overclock is becoming too much and hindering performance. Will also weed out any obvious instabilities.

Sleeping Dogs Extreme benchmark for testing the complete robustness of your overclock.

If it fails occasionally on SD then it's not overall stable and can do with dialing down a touch or adding more voltage.

Heaven for 10-20 loops on ridiculous settings.
Then test with a game.

Thanks, I don't have sleeping dogs so I will go with heaven then see if my games like it.
