I don't use it because I have learned that its Small, Medium and Large Data Set tests are the same as Prime95's Small FFTs, Blend, and Large, in-place FFTs tests. It also uses the same linpack tests that the other linpack testing programs use (and OCCT doesn't give the user as much control over the way the test runs). On top of all that, OCCT takes a long time to open. In 64-bit Windows, it can take 4-6 seconds. In 32-bit, it can take 10-14 or 15 seconds. But Prime95 takes around a half a second and so does LinX.
So, it seems like it's rather pointless to use OCCT. However, some people have said that while their overclock was able to withstand several hours of a test in Prime95, using OCCT told them a different story. But it seems that most people continue to use their computer while they run a stress test, and so I think that this is why people are finding different results between Prime95 and OCCT. I mean, a stress test will last longer if you use the computer while it's running.
Now, I suppose you're wondering what I think about OCCT's GPU and PSU tests. Well to be honest, I have never used them.
I don't overclock my GPU, nor do I want software to test my PSU. Edited by TwoCables - 10/30/09 at 12:06pm
