4770k max safe voltage for 24/7 usage?

post #1 of 3
Thread Starter 
I recently purchased a 4770k but unfortunately it is a mediocre overclocker at best.

It has been delidded and is running under a H100i with load temps around 60 -65 celcius mark currently at 4.5Ghz 1.29v.

I want to push this thing further, at least to 4.7Ghz. Assuming temps stay reasonable, what is the maximum voltage I should go to?

Thanks thumb.gif

If it were my chip I wouldn't exceed 1.35v for 24/7 use - but I'm fairly conservative when it comes to that sort of thing.

If you were on air cooling my recommendation would be even lower due to heat concerns, but I think you'd be ok at 1.35v long term using water cooling.

YMMV though depending on your cpu load temps.

With all that being said, I personally think you're chasing ghosts if you have to increase the vcore by .06v to gain an extra .1Ghz in processor speed. At some threshold you'll be at the point of diminishing returns and @ 4.5Ghz using 1.29v you just aren't going to see much benefit in hitting 4.6 or 4.7Ghz (other than saying you can or you did).

If you have delieded pretty much anything under 1.4-1.45 for 24/7

I currently have a 5ghz 4770k running at 1.51v 24/7 and another at 4.5ghz but imo 4.5ghz and anything under 1.4 is awesome and will last a very long time way past point of upgrade. thumb.gif

And live wevsspot said anything past 4.5ghz isnt going to show much diffrence esp if only using 1 gpu
IMO 4.5ghz is the sweet spot for performance vs lifespan/abuse
