i7 4790k max overclock on air ?

What have you achieved with this ?

It all depends on what cooler you have.
Stock - Dont even try overclocking
Noctua NH-D14 - Should be able to handle 4.7ghz or 4.8 depending on the bin of your chip

Honestly most chips run out of ability before they run out of thermals if you have a good air cooler. (At least at voltages you would consider leaving it at 24/7)

Well, i have a cheap deepcool maelstorm 240t. I wanted to create this thread so that everybody can tell their achievement with what cooling and voltage. I personally with the obove not that good cooler overclocked mine to 4.7Ghz with no more than 1.2v core voltage. Is that a good thing ? Cheers

4.7 with 1.2v is a good overclock.

For me I used to get
4.7 at 1.25v
4.8 at 1.3v
4.9 at 1.36v
5 at 1.45v

I regret running it at 1.45v as the electron migration really devastated my CPU. I can no longer run at those speeds with those voltages. For 4.7, I now need 1.32v for the system to be stable. So now im running at 4.4 at 1.2v

How long have you used it with those voltages ? I also use mine at 4.4 now.

I ran 5ghz for about 4 days before it became unstable

Only 4 days wow 🙁 I thought you'll say months Too bad. When i overclocked mine few months ago i did some benchmarks and games and realized there is no huge difference in performance so i left it at stock. Other thing is that my cooler is not good enough for reasonable clock.
