Overclocking Hero VII & 4790K

[vetequk]

I am new to this so i tried a manual overclock adjusting the voltage to 1.280 at 48 & it failed the stress test (using realbench).

I then set the voltage to auto, left the multiplier at 48 & it passed the 15min stress test, maximum temp was 82 & voltage was 1.373v.

My question are what is the maximum safe voltage?

There were 2 cores that did not reach a maximum temp of 70, does that mean I can take the multiplier on these cores up to 49?


Thanks

hello vetequk

Yes you can, but it's best to set your voltage manually so you know it's not getting over volted, you have more control doing it manually.

But since you did do a run on auto voltage and it was pulling 1.373v at 4.8Ghz, you'll need somewhere close to that.

Try this: You know it passes at 4.8GHz with 1.373v


Set the ai overclock tuner to manual, set the core ratio to 49 and cpu core voltage override to 1.38v.

Temperature controls how far you can overclock and your temps are still good. You can take the temp up to 90c in realbench but I don't like to let it there very long at all.

See if she'll go at 49 and 1.38v, if not keep raising the voltage .01v until you get it stable, or the temps no longer allow.

I tried manual voltage up to 1.42 @ 49 & it failed the stress test. how much voltage can the cpu take.

Temps were up to 85.

if you can't get 49 stable at 1.45v - 1.46v go with 48.

There is a point where your cpu will hit a wall and 4.9GHz seems to be it on the 4790k. When you hit the wall your cpu will need a lot more voltage to hit the next 100MHz and it seems may have hit it.

Go by your cpu temps, don't let them go over 90c when running the stress test.

Temps tell you how far you can go.
