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.  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. -Curtis |

One more for k=177:
177*2^282546-1 (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 NiceMedTexMD on many new primes! |

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