Henry,

You either found two real fast primes close together or you have another bad machine producing erroneous primes. Can you check on that?


Thanks,
Gary

Checking the primes. It is the same machine. I was certain that it was fixed after a bios update. Either I have been lucky or that isn't the case.
When I double checked the work on my own server(about a weeks work ~1000 tests) there were two mismatches(both wrong the first time before the bios update). Even then it was fairly stable.
I was watching amazon prime yesterday evening. It is possible that this is related to hardware decoding at the same time. Not certain that the times match up completely.

I might have to just keep this machine off public servers as the problem seems to be false primes.

Both "primes" tested composite with a prp test. This is getting frustrating. What sort of testing do I need to do to confirm that this pc is stable? The errors are so infrequent.

I suppose these two:

1000000000:M:1:2:258
529 1440053
429 1440063

from

http://www.noprimeleftbehind.net/sta...p?content=port

edit:
529*2^1440053-1 is not prime. LLR Res64: 3036F257192A31EA Time : 785.791 sec.
429*2^1440063-1 is not prime. LLR Res64: FF7F05B3A32F301C Time : 781.643 sec.

Yes those are the two "prime" composites that were reported to me.

Henry, would it be possible for you to post a list of tests done by that machine since the last time that you had the problem? We will attempt to delete the k/n pairs from the server and re-add them so that they can be retested. Thanks.
