Actually, it way my mistake, since GPU2, which has no monitor output attached, and is not in SLI, was not stress tested.
I found out that it was unstable at certain clock. Now running DC on smallest exponent again.

Any sources and binaries for v1.68? (the one with interactive aggressive/polite mode). I will be home in about 23 hours and I am eager to try it. Anyhow, if not, I will still keep you posted with v1.65's progress. I understand that you have other things to do too, sorry for being such a pain in the butt.

Hi guys.
Could someone please tell me, how the inputfile for CL had to look? I tried the exponents alone and the line from the worktodo.txt of P95 but there always CL tells me to start with the first exponent and then closes. Thanks in advance.
