From the 177th Street :smile: :cool:

177*2^769026-1 (231503 digits)

This should be enough to overtake "12121" and return to the 8th position by score. :grin:

Just to secure our 8-th place :smile:
101*2^900358-1 :banana:

Wow - congrats Cruelty. Was the last prime for this at n=94k?

Cruelty, nice prime, congrats! :cool:

This is now the 4th largest prime found by RPS.

As for k=101, not only was the last prime at 94k, but the one before was at 9k:
9990, 94194, 900358
Is the next one going to be at 9M ? :surprised

Thanks :smile:
I think that taking k=101 till n=9M would take a single person couple of years... right now I have plans till n=2M and then I'll decide what to do next :unsure:

Fantastic Amphoria! :grin:

Very Nice:surprised

amphoria, nice prime, congratulations!:w00t:

Our first megabit prime from team search! :cool:

I built a Conroe system, and it produced a prime in its 2nd day:
3803443215*2^491104-1 is prime.
I double-checked on my P4 just in case.

For those curious, a stock E6300 Core2Duo LLRs at about P4-3400 speed, and sieves at roughly Sempron-3400 speed (with DDR400). These estimates were run simultaneously- one LLR thread, one NewPgen, assigned to different cores.

Nice prime on a nice machine! :cool:

[QUOTE=VBCurtis;88274]I built a Conroe system, and it produced a prime in its 2nd day[/QUOTE] you should be able to achieve at least 2.1 or 2.33 GHz, by simple increase in FSB frequency :smile:
This would give you additional 16-30% performance for "free" :smile:

Cruelty-- if I don't get 3.0Ghz, I'll be disappointed. But that has to wait for a new board; current board only has FSB up to 300, so I'm at 2.1Ghz at present. CPU temp 46C with both cores 100% load, with a Zalman 9500 cooler (fan throttling for silence).

The third one from k=25 with more than half a million binary bits: 587585, 716769, and now 942563. :surprised

Thanks! I am systematically approaching the 1-megabit barrier :showoff:

Nice prime Larry! :smile:

Larry,
Tremendous! :w00t:
Dry spell long forgotten.

WoW very nice.:surprised

231*2^959375-1 (288804 digits)!

I guess it just took a little public whining to make the primes come out :geek:

Wow, rank 154... Congrats :smile:

Congratulations!
Here goes my team's TOP-5 prime :wink:

Two weekend finds:
201 302666
197 325610
End of 6-week drought.

99 586088 is prime. The Core2Duo produces its second result.

Congratulations VBCurtis!
BTW: at what speed are you actually running this CPU?

Totally stock, 1.86 Ghz. The junk ECS board that came with the Fry's special is not stable with any overclock, and I'm waiting until Dec/Jan for the new generation of boards to decide what good OC board& memory to get for it. For now, it's just a Prime cruncher (one LLR, one NewPGen); when I get a board and good DDR2, it will be my main system; 2700-2800 Mhz will be the target with LLRx2 stable room temp 80F.

Does anyone know why/how I got a flying penguin as my avatar? I don't mind it, but I didn't put it there. Maybe it's a hippogriff. {shrug}

201 is proving very rich:
201 374891
201 376594
201 382059
are all prime. I will be done to 500k in the next week, the end of the sieve.. I guess I should start a new sieve, since this k is producing so many primes (8 from 285k to 450k).
