Temp question

[Poofu]

so i've overclocked my i7 3770k to 4.4ghz it idles around 40-50 but at max load (is: rendering video) its about 85-95c is that ok?

[extremescouter]

Those temps seems a little high. What cooler are you using? 

[tabuburn]

Those load temps are a bit too high. CPU's start to throttle their performance at those temperatures to prevent killing themselves. What voltages are you using for that overclock and what cooler are you using?

[XiaoPigs]

That's a bit too high for my liking especially the load temps. Try reseating your cooler or replacing the thermal paste

I wouldn't rush to do that. Perhaps the overclock is just too high for the cooler. Maybe it's a Hyper 212.

 

Anyway, what's the cooler?

I'm using an h80i and as for the voltages i believe im' have those set to auto

That's why your temps are so high. A motherboard's auto-OC greatly exaggerates the voltage needed for the overclock. Try manually overclocking it and set the voltages lower for that 4.4GHz.

[FluffyNuggets]

You should only be in the 70's at that clock. Sounds like you need a better cooler, maybe a h110 or whatever they are now. When I had my H100 my 2600k never broke 76c @4.4 at load.

what do you think an appropriate voltage would be?

[Thunderjolt]

Try something around 1.25v and go up or down depending on how it goes.

[tabuburn]

what do you think an appropriate voltage would be?

Yeah, somewhere around this region.

ok so i set the voltage to 1.23v and its running just fine now idle around 35-40 thanks for the help :)

No prob. What are you getting for load temps?

not sure i'll be rendering out a video tonight so i should be able to find out then

I tried auto voltage once, yesterday, on an asus p8. The auto voltages were very tame, about 1.11-1.23, from 4.0 to 4.2. I then skipped 43x and went to 44x, knowing that my IB was good for 45x with that kind of voltage. In Windows, cpu-z was displaying 1.42v while I was "clicking and dragging all over the desktop" to see what the turbo voltage was.

 

Everything was all on auto, I just wanted to see what you can do w/o changing much. You can't do more than 4.3 with the auto voltage. You will have temp problems unless you prepare with much better cooling than an h80i..

 

 

 

Just a story, you can find overclocking guides everywhere. Read them all...

If you have time run Prime 95 to check if the overclock is stable!

On my Intel DZ77RE-75K motherboard, at 4.5Ghz it was sending ~1.45 volts to the CPU! 

The auto over clock(OC Genie) on my old MSI P67-GD55 was much better, it took the CPU to 4.4Ghz and the voltage to 1.33, still too high, but better than the Intel! 

[grayperview]

1.23 is very good for 4.4ghz if it is indeed stable, remember to enable load line calibration, to stop voltage droop, this will help you gain a more stable overclock, for 4.4ghz i suspect you may need to up your voltage to 1.26 for full stability...

 

I'd recommend you run OCCT or Prime95 for a few hours to test, It may take a few days to tune everything in, be prepared to have to change the voltages a few times to get the correct settings, and remember only ever go up or down .010 of a volt each time.

Either bring down the overclock on the CPU or change the CPU cooler for a stronger one because at those temps your CPU wont last long. However, on the up side with those temperatures you may be able to fry an egg or two on a side panel at load.

[Poofu]

I'm currently rendering a video the CPU usage is 100% and the temperatures are not exceeding 80 Celsius but I did only overclock it to 4.3 GH Z

Those temps are okay. Just make sure they don't go past that. What cooler are you using? At the 1.23v you are using, you might even get away with 4.4GHz.

H80i

[JordanMac]

try bringing the voltage down but keeping it stable otherwise you may need to get a better cooler like an AIO liquid cooler

[tabuburn]

H80i

Ok. You might be at the limit to what that cooler can give you.
