Thank you for report.

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 2-3 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. :blush:

DC successful !
2^6972593 - 1 is indeed a prime:smile:

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.

Run cudalucas without args to find out the meaning of commands.

(still not interactively changeable)

^C caught. Writing checkpoint.[/CODE]worktodo.txt had two test exponents (from my completed double-checks), see attached. I also tried it with the two exponents in reversed order, and it started with the correct one. (Note that "check" is the folder I made for checkpoint files to be saved in. That also seems to be working correctly.)

I hope this helps.

EDIT: I stated incorrectly in a previous post that the worktodo.txt in the command line would be preceded by -r. LaurV corrected this error. "-r" runs a self-test.

Thanks a lot.

I found my error. CL created a ini file with the number of the line where to start. I deleted thiese file and then it worked.

Again, thanks a lot.
