Overclocking i5 4670k

[Antm4n]

Hey, I'm currently in the process of overclocking my CPU and I have the multiplier at x42 so it's running at 4.2Ghz and the core voltage at 1.15, in Prime95 I get a max temp of 76 Degrees but it doesn't hit that often.

 

I was wondering if this is safe because I know it wont hit that in everyday use and for playing games. I've had a look around and some people have said in Prime95 85-90 Degrees is max but other people have said don't get it go above 70-75. It seems to be running stable but I just wanted to make sure before I keep it.

The cooler I have is a Hyper 212 EVO.

 

Thanks a bunch for any help!

 

I'll attach a picture of the Core Temp window just incase it helps.

Update: I've had Prime95 running for just over an hour and the temps have no changed and it still seems to be running stable.

Try to play games with the overclocked CPU. And see the temps, i think the 75 degrees temp is just in stress test and not in the real situation where you play games or doing something else.

Cheers for the response!

I'm just about to go to bed. It's 2:45am aha, I'll try when I wake up..I'm playing through Metro Last Light so I'll have core temp running on the second screen and see how I get on.

Thanks.

I played metro for a while and the max it hit was 64 Degrees

Those temps are more then safe, my 4670k gets around the same temps under prime95. Like others have said that is a stress test and normal gaming/application use will not push the heats that high.

 

You don't have anything to worry about.

Ah ok nice one thanks for that

 

What do you have your 4670k running at? You reckon hitting 80 Degrees is okay during Prime95? I started hitting it when I tried running 1.200 Volts and 4.4GHz and I didn't know if it was okay haha.

I can't get my 4670k above 4.3. The haswell chips are known for being hot and giving bad OC. I assume 80 is a little hot but again that is under prime95 so game heats should be less. If you are not comfortable then just turn it down a notch.

Yea I want to keep it running below 80 and 1.2 volts was the lowest I could get it before it bluescreens after 10 mins of Prime95. I probably just keep it on 4.2GHz for now because it seems to run well with no problems.

 

I did manage to get a Cinebench test done on 4.4GHz and I got 20 or so points more than 4.2GHz so not a 'massive' difference.

Anything below 85C under heavy stress is good. Anything under 75C on normal load like games is also good. You shouldn't use Prime though. Aida64, OCCT etc. are much better and safer. You should also remember that clocks themselves don't really raise temps. Voltage does.
