I noticed that mlucas now supports exponents up to around nine billion. Although I don't expect anyone to test those numbers anytime soon, this is really cool nonetheless. :smile:

Did your computer crash for any reason?

In my experience, this can cause Prime95 to lose settings in rare cases.

I forgot to mention that both CPUs have the same 3.5 GHz base clock speed. However, the new series does have eight (up from six) memory channels. Would this have a significant effect on power usage?
