Smaller exponents will also run at 100C.

Try running with fewer cores, that might help with the temperature. If we can't get the big exponents to run at a temperature you are comfortable with,...

Yes



This could well be a new condition in 30.8. I believe it was James that had some case where PauseWhileRunning and CERTs did not behave well. I don't remember the details.

You are highly unlikely to find a factor using P-1 on exponents below 10000. GMP-ECM is also very fast on these tiny numbers and has been available for many years.

It is possible but you must use 30.8b15. Give it all the RAM you can spare as long as the system does not start thrashing during stage 2.

Thanks for the great data! From that I see that the "prime95 guessed optimal B2/B1" is not terribly bad. We need to wait for a prime95 that is fully optimized in stage 2. Then gather similar data...

I'm no expert, I think it is an issue with memory timing signals and may not be fixable.

I was thinking after completing P-1 to 20M we might embark on ECM. Along the lines of t35 up to exponent 1M, t30 up to 5M, t25 up to 10M (these are just example t-numbers and exponents). Of course,...

The best B2 value is determined by shortest time to complete the "t" level you are working on.
