Prime95 Failed worker ? i7 2600k

post #1 of 8
Thread Starter 
Ive just recently down-clocked my overclock to 4.6 @ 1.38v.
~40 minutes in, i got a failed worker but the rest kept going.

Can anyone shed some light as to why this would happen?
Ive kinda ruled out voltage but i could be wrong.
Heres a screenshot. TY in advance

Could also try upping the RAM subsystem voltage a touch, vccio or vtt. 1.05 is stock, 1155 is really picky about RAM but almost everyone reports that raising it a bit helps stability. 1.10v-1.15v is pretty common, 1.20v is general consensus as safe for every day usage. I'd go up .02v at a time, or even just jump it to 1.10v and try again. I'm at 1866 on 1866 rated RAM and require 1.15v.

ALSO IMPORTANT: Set your RAM speed (2133), voltage, and 'big 5' timings (like 9-11-9-27-1T or 2T) whatever they are rated for, MANUALLY don't let your system set them via auto. Also seems to help many people out with stability.

So you wouldn't recommend using the XMP profile?
My vtt is @ 1.16 atm, i also heard that a failed worker could be RAM related..
I will try a stress test now...
