well done now you need to go for a mdigit prime:smile:
it might be fun searching for a prime that would have 1m digits in base3 then base4 and so on:smile:

[quote=henryzz;151019]well done now you need to go for a mdigit prime:smile:[/quote]

It's quite a step from 19 minutes pr test to 9-10 hours pr test :smile:

My next goal is to help as much as i can on the 6th drive, and perhaps put some cpus on the stalled 3rd drive.

Congrats, mcduck!

If you decide to look for larger primes, we have well-sieved files for 5, 15, and 17- though the 3rd drive is also somewhere near/above 1.5mbits.

Thanks :>

For the time beeing I have decided to stay on the 6th drive. I expect to get some new hardware (intel skulltrail 8 core system) in january and will put that one to use searching for larger primes (3rd and 17).

Also, a huge thanks to those who sieved the 6th drive!
