This is a problem I've only encountered somewhat recently.. But twice now, I've gotten a really good stable overclock out of my computer, and then gone to start it up the next day and it wont post with the same settings... It seems to be related to my cpu-nb, but the conditions are odd...

The settings the first time
CPU 4.3GHz 1.455v
CPU-NB 3000MHz 1.39v
Ram 1333 9-9-9-24

stable for 20 runs of IBT, then the next day it wont post, and i had to clear the cmos

The settings the second time
CPU 4.3GHz 1.455v
CPU-NB 3000MHz 1.45v (1.39 wasnt stable anymore)
Ram 1333 6-6-6-18

same thing, stable that night, then wouldnt post the next morning...

Is something degrading my cpu, or is my motherboard going crazy on me, or am I an idiot who's missing something obvious?

tl;dr Version
Why is my overclock completely stable until i turn my computer back on the next day

What spec ??? And Overclock doesn't hurry !
790FX GD7 is am3 need Keep nb at 2000 as posible and cpunb at 1.18-1.2v max, ran at 4.3ghz need more than 1.45 maybe 1.5v or more. Try first ran you ram at 3:8 (1333) 9-9-9-24

(if you need anything else just ask)

I overclocked my cpu frequency first and checked for stability, and then overclocked my cpu-nb and checked for stability, then my ram and checked for stability.. They should all be fine =\
