Phil, thanks. We just had a few lucky days :cool: As for the number of primes the bottom limit to enter Top-5000 it's moving upward rapidly and one needs new primes all the time to stay afloat. :smile:

I was afraid I have to go to much higher [I]n[/I] to find the next k=73 prime after confirming the one at n=212451. k=73 is now continuously checked to n=462k and with gaps to 500k. Will continue to mid-500.

I just retested the number with the following two boxes:

As for the composite by Thomas, let's hope it was a typo.

[/CODE]

After I've got noticed about the non-primality, I did a verification run on the same machine (AthlonXP 2400+ @ 2GHz, 512 MB, Windows 2000, LLR 3.6.2):

[CODE]
151*2^413933-1 is not prime. LLR Res64: 8440059416AD03E7 Time : 492.292 sec.
[/CODE]

I'll do another verification run on a Linux P4 for a few of the other candidates, to see if the residues match.

I should add that I never had any problems on this machine. I'm using it for about 3 years now for finding quite a lot of "true" primes...

Seems, that this problem isn't restricted to grobie's machine.
And it doesn't seem to be SSE2 related, since on the Athlon LLR uses the non-SSE2 code.

[B]Cruelty[/B], can you consider posting your prime(s) here. Why not? Who knows when will Top-5000 be back again. It was supposed to be fixed on Monday, but Monday is over. And once it's functional again it's going to be busy verifying accumulated primes for a day or two. We are searching for primes because it's fun, not for the sake of any particular web site.
