Ok , uzeo pravo napajanje , sad se ne grije i skužio di je problem , jedan frajer imao isti slučaj :
"hi peeps,

i have been having problems clocking my 7850 BE and wondered if anyone has any suggestions. the cpu is running in my gigabyte ga-m57sli-s4 motherboard. i contacted gigabyte before i bought the cpu as it only showed the 7750 in there cpu support list, gigabyte then said it was supported and gave me the latest bios. i had to manually set the cpu voltage to 1.2v as the board wanted to run at 1.325v on auto. the cpu runs fine at 2.8ghz and with the voltage set to 1.2v but if i adjust the clock multiplier ever to 2.9ghz i will get a blue screen. if i set the voltage to 1.25v and set to 2.9ghz the pc will boot and go into windows, but i know straight away the pc isnt liking it as my mouse pointer becomes a white pointer instead of the usual gold colour. if i then try to run 3dmark it will lock up. has anyone got any idea of why this isnt overclocking even by this small amount. thanks in advance for any replies."


A sad može riješeno
