CPU Overclocking

[Pr3tax]

I overclocked my i7 4770k to 4.2GHz, where I find the temperatures to be comfortable, but I notice some weird glitches and freezes sometimes.
So I'm asking you for help, I put my CPU Voltage at 1.2V, and wonder how I can make it more stable.

I run Windows 8.1 64-bit.

You can increase the amount of voltage or reduce the overclock to make it more stable.

increase the voltage and test it. You may just have to run at a lower speed if you cant get it stable. If it is not running stable it will not performance as good as a lower clock speed.

How much should I increase the voltage by? I know the 4770k can take more then 4.2, but my cooler can't handle it.

increase by .1 increments until temps get too high. Or just just to 1.25 and watch the temps during a stress test.

Well my MB allows me in increase and Recomende that i only do it by 0.06750000 volts etc + or - at a single time (Or something like it :3 )

.01 actually. Going from 1.2 to 1.3 is a pretty steep jump in voltage.

Put it to 1.22V, and ran a 1gb test on intelburntest. Now it reaches 80C and jumps back to 3.5GHz. Should I leave it?

[79wjd]

Yes....well, I'd back the voltage down. You seemed to have just gotten a bad overclocker. I'd personally prefer to stay around 70-75 max.

Try running same voltige and decresing speed so its bit more stable

Update: Reduced speed so it runs at 4.1 when 3 and 4 cores are active, and 4.2 when 1 or 2 are active (Just testing for stability) with uncore at 4.2. Voltage is at 1.21 due to high temps. Still throttling ALOT, as soon as it reaches ~78C it goes directly back down to 3.5 and won't go back until around 65C. Guessing temps won't reach 90 if the throttle isn't active, but have no idea how.
