is this i7 4790k overclock ok?

adrixmetalcore · Aug 16, 2014

I'm using the 4790k and overclocked it to 4.6ghz with 1.275V
I'm also using 2133mhz ram
Is the voltage too high?
I tested OCCT for 25 minutes and didn't fail. What other tests should I make?

Anything higher than 1.425 is getting high you got a nice chip and a nice overclock.

Yeah, that voltage is totally fine. Did you have any luck on lower voltages than that? I overclocked a friends 4790k and we got it to 4.6Ghz with a bit lower voltage using 2133Mhz RAM as well. Either way, nice overclock

Lower than that, I only tried 1.250 and it failed. Also with my actual OC the temps are a bit high imo... while running OCCT i get temps from 65 to 80 and sometimes it gets near 90. I'm using a Noctua nh-15d cooler with mx-4 thermal paste. My case is a define R4. Are these temps normal?

kunthakenthe · Aug 16, 2014

no with that cooler and that low voltage i think you need to speed up your fan speed or replace the thermal paste.

adrixmetalcore · Aug 16, 2014

i think my fans are set to be at 100% when the cpu hits 75ºC. does this thermal paste have a burn-in time? I re-installed the cooler yesterday

kunthakenthe · Aug 16, 2014

no the thermal paste doesnt run out or have burn in time. something is wrong try downloading cpu temps and checking it out.

My 4790k runs the same temps on my 4.6 OC with 1.224v and it's consistent on all the temp monitoring software I've used. Either my sensors are borked or the TIM is not up to snuff.

What batch of chip do you have?

kunthakenthe · Aug 16, 2014

i dont have a i7 but i can tell you the temps shouldnt be hitting 90c. you have sensors in the chip or in case or what. have you check your cpu cooler to see if its working. try opening up both sides of the case and seeing if temps go down.

adrixmetalcore · Aug 17, 2014

I've done some tests today, my results:

Gaming (watch dogs maxed), no side doors open or front, additional fans spinning at minimum speed: Average 60ºC max 71ºC
OCCT, All doors open and fans spinning at max: 78ºC max on all cores except for #3 which was 73ºC

Should I replace thermal paste?

adrixmetalcore :

maybe also are you stress testing.

Ellis_D · Aug 17, 2014

adrixmetalcore :

What's your ambient temperature?

adrixmetalcore · Aug 18, 2014

Isnt OCCT a stress test?
Room temp: 20-25

kunthakenthe · Aug 18, 2014

adrixmetalcore :

if its a stress temp that would explain the high temps.

adrixmetalcore · Aug 19, 2014

kunthakenthe :

I'm pretty sure it is a stress test

So, does that mean everything is ok?
I'm not a pro at ocing but I want to have sure that everything is working properly and that the cpu will last a reasonable amount of time

yeah it should be test your temps on a game. if its in the low 60c high 50c your good.

kunthakenthe · Aug 19, 2014

also yes always stress test while oc.

adrixmetalcore · Aug 19, 2014

alright thnx
