[quote=ET_;230156]I tested it on my Windows 7 64 bit and gave me no error. Would you mind sending your resume and results logfiles to me, so that I will be able to check what may be wrong?

i started another compute but at the end, i'll send you this.

no factor for M3321931967 from 2^76 to 2^77 [mfaktc 0.10 95bit_mul32]

At last. Big problem with nvidia driver.

I have been working on my own program for trial factoring and have been running it on some ranges to make sure the code is working.

It actually found a factor in this range.
[CODE]M3321934709 has a factor: 378121774679999658041[/CODE]

I then double checked it with factor5.

The win32 version of factor5 also finds it.
[CODE]M3321934709 has a factor: 378121774679999658041 - Program: L5.0x[/CODE]

Are you using the win32 version of factor5?

You may want to try re-running it on your machine to make sure it does pick it up.

gjmccrac,

This is disturbing and important, thanks for letting me know.

I'm using factor4, as my understanding is that that's the most suitable version of the software for that PC (Windows 98 on a Pentium II).

I will run the exponent a second time -- it'll take 11 days to get the result again.

Now, the thing is: How often does something like this happen? And, regardless of what the new result is, can we really trust its output anymore?

Anybody reading this who has experience with this sort of thing -- feel free to pitch in! Besides re-running the test, what do we do?

Rodrigo
