***Running Prime95, 10min into it. Core#3/4 had a error, message as fallowing, (core3)FATAL ERROR: Rounding was 0.4995227891, expected less than 0.4 and (core4) FATAL ERROR: Rounding was 0.5, expected less than 0.4. As a result of this error, those core auto stopped and 1 and 2 keep going.



Someone prime95 will run for about 1min and the error comes up, sometimes for 5mins.....


Anyone know what this means? and how to FIX it?







I left my DRAM volt on auto...

the 1.65 Volt max performance DDR3 u can look other thread in the forum!
Increase Vcore / VDIM step by step until Maximum,

example your's clock 3.5 ghz test prime stabil don't increase anything !
in Bios many option to increase vcore, multiplier & Vdim do step by step

While overclocking you should lower ram multiplyer so your only overclocking cpu.
For your ram. leave it at 1.5V but if you want to overclock that aswell, 1.65V is perfectly safe for DDR3.

What CPU/Mobo and RAM are you using?
