Any updates?

I am very interested in the runtimes for a GTX560 Ti related to Phenom II 955, Linux64.
How many hours will it take to prove primality of M4264380 on it?
I would of course be available with this card for a test.

Saving you the heartache: It's not prime. :no:

Just for clarification: 4264380 is not prime, so (2^4264380)-1 cannot be prime.

All this for a simple typo? :huh:

Yes. :smile:

If moebius receives any time estimates for an exponent an order of magnitude smaller than the one he's (supposedly) interested in, they aren't gonna help him that much, either, so hinting at what happened seemed like a reasonable route to follow.

Considering the intended exponent is pretty obvious, it would be better if we could just say something to the effect of:
"M4264380[B]1[/B] would take X hours."
But the program isn't released, so nobody so far has really been able to answer it...

Too bad, I thought I had found the first even prime number ... haha

I do not think in such a trivial range of numbers.

Back to King Kurly's question: Which GPU should be in my future, assuming my budget is only $500 or so? 100GHz days per day makes my Phenom II x6 seem, well, puny!
