Even after a P-1 run, you should still see something like 1/85 to 1/90 or so from 74 to 75.

No problem. I passed all self tests also. I guess I'm just very unlucky.

Hmmm... Interesting.

OK, well, since statistics has no memory let's expect and hope that your future results begin being more nominal.

May I ask you two things? Have you run the self test on all your cards? Separately, how many of your cards are AMD vs. NVIDIA?

I am asking this only because the AMD and NVIDIA architectures are rather seriously different. And, your stats are well outside being "unlucky". To be clear, this is simply a "hmmmm..." thing.

22% ghz nvidia.

Well guess it's just bad luck, I just tested each 290x with a found factor TF75 and each of them found a factor,
71572651 66328541 72244427 71455331.

Thanks for running those tests! Encouraging.

Keep in mind that -st/-st2 is a selftest for the software, not for the hardware!

Completely sure about that? We know the software works correctly, it was verified before release. so any testing in my computer is a test of the hardware...

Just because the software works on his card/driver/cuda version doesn't mean the same for yours. The tests are precisely for figuring out which of those combinations the software *does* work for. It happens to include the author's cards, as well as yours.

So success is a good sign, but not proof of anything hardware related? It's more the combination of drivers, versions, and compatibility?

It still seems that hardware errors could cause a failure, even if everything else was in agreement.
