Curtis,
No problems. Yes, 11 primes in the 200-400k range is a lot! More than any of 16 k's in our First Drive (processed to about 360k now). If you can sieve more go for it, and if/when you cannot test it by yourself we'll help you. :cool:

BTW, a new prime for k<300
177*2^277458-1 (83526 digits)

Make that 12 in the 200-400k range:
3803443215 396082 is prime.
I guess I'll be sieving to 1 million and continuing this k-value past 500k.
Sieving is slow- it has to be entered into NewPGen in factored form, so I only sieved the 0-500k range to 600B.

One more for k=177:
[B]177*2^282546-1[/B] (85058 digits)

Curtis, when k>2^31, it's faster to sieve k*2^n-1 using ksieve. If you cannot find a copy of ksieve let me know, I'll send you one.

And congrats to [B]NiceMedTexMD[/B] on many new primes!

It's nice to see that both drives are now producing primes over 100k digits :bounce:
