One core slower than the others?

[Muel]

Hey, Just ran Prime95 because I've been having a lot of instability issues recently, and it completed 97 tests on cores 1, 3 and 4, but 2 only completely 93. 0 errors and 0 warnings on all of them.

Could this be related? Not overclocked in ages, just replaced my motherboard to try to solve these lockups I've been having, but to no avail.

Been fine today though since I turned off CnQ and upped the RAM voltage to 1.63v...

Should they all be the same speed, or is it normal for one to be computing slightly slower than the others?

Nothing to worry about, it just how it goes. My does the same.

Its not a fault. It is because the all the cores are also running other tasks than prime and are loaded differently so finish at different times

Can't believe that didn't twig...

Yep, Prime runs in low priority mode IIRC so other processes will get priority over it
