Overclocking and Stress Testing an I7 4790K

Recommended Posts

Posted · Original PosterOP

Its my first time overclocking and I am trying to follow the LTT guide on how to overclock this chip, but I feel like at his settings, my CPU is getting too hot. On a 5 minute stress test at 4.4 GHZ and at 1.25 V, the temperature gets to 100 Degrees Celsius on its hottest core and in the high 90s for the rest. I have the Swiftech H240 AIO for cooling, and the second the test is over the chip drops into the 40s. Is this normal?

What stress test are you using? I believe in something like Prime95 that's quite normal given your setup. Aida would probably show something similar.

 

Also, I bet you could get away with 4.5 or even 4.6 at 1.23


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

Yes 100c on any core is much too hot. Back when I had my 4790k I ran it at 4.8ghz (don't remember the voltage) and it topped out around 80-85. Some of this is out of our control as this CPU is using a shitty paste between the die and the IHS, rather than solder. I had the H100i (CoolIt Pump) that helped bring temps down a bit, but 85 is still scorching. I personally wouldn't go over 90c so keep that in mind as your overclock.

I'm running powerMAX for the stress test

the one with pump right behind the radiator blocking airflow from one of the two fans? No wonder why it got so hot.

I've never used it, but there is a warning at the top of the download page about damaging components so it seems pretty intense. How do your temps fare in gaming?


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

It's never been a problem. I'm running it on Prime95 now and I'm getting the same results

yep, seems about right. In gaming if you're around 80 max you're all set, is that what you get?

yeah, usually no higher than 81

you can still drop the voltage of course, to see what the lowest stable is.
