207 is pausing, focusing all 3 cores on 31

(630k-570k) P4 LLRing 31 at 645k
(750k-800k) Sempron LLring at 751k
(870k and up) Celeron LLRing at 871k

Steven, I'm not sure how to interpret your first line:

[QUOTE](630k-570k) P4 LLRing 31 at 645k [/QUOTE]

Does it mean you tested the 570-645k range?

nice big one for k=243
 

After just a little more than 3 days of searching n=500K-600K on core #4 of my k=243 search, I finally hit pay dirt for all of my gap filling and double-checking efforts. Rob missed a nice one by not searching all of the ranges of k=243 and then going virtually AWOL for nearly 2 years...

243*2^510491-1 is prime (153676 digits) :surprised

Nearly 120,000 bits bigger than my previous biggest. :smile:

This makes a pretty good case for checking all of the ranges, not just the ones shortly before a fftlen increase.

I'll call this my payback for a barren double-check stretch of k=289 from n=90K-500K.

4 cores are on it, one each started at n=230K, 333.3K, 400K, and 500K. The ranges completed so far are on my web page.

yes. the number inside the parentheses is the exponent which is assigned to the machine. and the there's typo in the first line. it suppose to be 630 to 750k

David informed me that he tested k=137 all the way to n=2M and stopped there.

Cruelty, if you want you can continue frome there...

k=243 strikes again for n>500K only n=8K larger
 

243*2^518736-1 is prime! (156158 digits) :surprised


Someone really missed the boat on this one!

Gary-
please post primes in the "post primes here" thread, not in this thread. This is for status updates, not for prime-posting. This keeps threads less cluttered.

k=81 Status
 

k=81 at 1025k. Continuing.

k=67
 

Reserving k=67.

k=147
 

Reserving k = 147 please.
