4770k OC

[AndréMelsom]

What should my voltage be for a i7 4770k @ 4,6 GHz?

[virusal19]

Everyones CPU is different, you will want to test it out yourself by slowly increasing (Or decreasing) the voltage.

 

Recommend starting at 1.300V and increase it or lower it if needed.

I'd disagree with virusal19. Don't go past 1.25V or at most 1.275V unless you have a dual-120mm air/water cooler. For voltages above that, you'd need better cooling.

 most 4670k/4770k will burn through your motherboard with air cooling at 1.3V :D

He has a H100i, I have a H100 and my 3770k can get to 4.9Ghz at 1.400V (Not Stable and haven't stress tested it for longer than 15 Minutes) . Pretty sure he'll be safe at 1.300V though.

did you read any review on the new haswell cpus? they get hot like crazy and really don't like to much voltage. and 1.3V is to much

[theathiast]

If your system is stable at 4.6GHz without applying any additional voltage then its fine as far as I know.

 

I'm kind of new to overclocking so I might be wrong.

Well.. No, haven't read any reviews yet but I suspect that It that be any worst than the IB chips... Right?

i have a H100i w/ SP120's

Thanks for the replies, it works gr8 with 1.275 volts, the stress testing has have been on for 30 min now and not too hot, Think i got a good one :D

Check out Newegg's overclocking guide. JJ explicitly states they purposely used a better than normal chip for the demonstration, and they needed a much beefier cooling solution than a normal closed loop cooler to keep it cool at/above 1.3V.

Fantastic! I'm hoping to get a 4770K in a month and I'm hoping it overclocks just as well as yours! :)

Well I never told him to stay at 1.300V I was telling him to test it first as a baseline hence why I said "...Increase or lower the voltage..."

And I said don't go past 1.275V i.e., don't even bother going to 1.3V. Doesn't matter, the man is happy with his overclock :)

Linus suggests 1.2v for 4.6 here.

[AndréMelsom]

Thanks for all the reply guys! You really helped. It is now stable at 1.2volts, and i am still running stress-testing
