Unfortunately I cant change voltage. Is this soo bad?

I overclock CPU to 4.2gHZ.

I just run Prime95 for about three hours without any crash or BSOD. On 4.0gHZ core voltage was 1.308V but now on 4.2gHZ is 1.296. How can be 4.2ghz core voltage lower than on 4.ghz?



What is next step I mean how high shoud overclock it?

For me the sweet spot was 4,7. Over that it was just numbers in Cpu-z. It depends how good your chip is and everything. I would go around 4,5 with safe voltages. You could always try how far it can take you. Up to you.

P.S. I had 5,0 with and entry-level mobo, so i wouldnt worry about yours.

That is extremely high voltage for that clock. At a minimum you should be looking to get 4.5 with the same volts. I've owned about 6 or 7 2500Ks and every single one would do 4.7 at 1.4v or less.

Also if you check out the Sandy Stable club OC 24/7 results you'll find that the average for 4.7GHz is right around 1.4v

My 4.5GHz needed 1.36V to get stable. I assume for 4.2GHz one would need 1.28V - voltage isn't an issue until you end up going beyond 1.3V, my 2500K ran 1.36V at 4.5GHz folding for a full year; no degredation thumb.gif

Mine ran at 1.45v for... A long time I don't even know. Never had an issue

Golden chip? I never dared OV mine beyond 1.4V because of the horror stories I'd heard about degradation. Got to be even more careful with Haswell now with the reduced die size - but this time I bought the overclocking plan so I'm pushing my voltage as much as temps allow.

Not golden at all. 5GHz at 1.45v is just above average. I typically stayed at 1.45 for my safe, 1.5v is also good depending how long you keep the chip.

The only sorta golden chip I had was a 3570K that did 4.9 at 1.31v
