Set max AA/AF and resolution and just let it loop. GPU stays over 90% usage basically always and Heaven gives the memory a proper workout so you can test for artifacts at the same time. Kill two birds with one stone, if you will.

OCCT will check for errors, just like ATITool did, so it's not just a torture test.
Heaven does crash out pretty good if your not stable, however OCCT will help you dial it in perfectly. It shows you how many errors occur.
Perhaps you need to DL the latest version of OCCT hit the GPU test, and check "check for errors"
