IS this a good overclock?

[Luke_stroud]

So basically....
I I have a 4790k
I overclocked to 4.7 at 1.265v after 2 mins of prime 95 I blue screened- baring in mind I was on 58 degrees..

So I ramped the voltage up to 1.8 and re ran prime 95 and after 10 times the time i ran it last time it is still running fine, except the temps are about 64 degrees!

SO the higher the voltage the more heat?
The less voltage the less stability?
Thanks a lot!

I don't believe 1.8V and that temperature!!!!!! 1.8 is crazy and dangerously high. Are you sure you are reading things right.

More voltage means more power use and higher temperatures. Both of my 4790Ks need/needed more than 1.3V to get a stable; 4.7Ghz overclock.

you mean 1.3v? at 1.8 you would fry your cpu lol..yes 64c degrees is nothing for 4790k, max working temparature is 105 degrees and it starts downlocking at over 90 degrees plus keep in mind that not anywhere else in real scenarios will you get such high temps than in prime 95, it's not even recommended to do tests in p95 because it can damage your cpu. Just keep your temps under 75 degrees for 24/7 stable operating and you will be fine

Oh lord... i meant 1.28 lolz i had it at 1.28 so that is all good? I havent tested for a long time, so can be sure 100% stable!

4.7Ghz at 1.280V is very good and those temperatures are also very good.

 

[G-star93]

just dont go over 1.4v and you'll be fine. I had 4790k running stable at 4.7ghz @1,29v and i got around 55 degrees in games

Looks like I got a lucky CPU!
What voltage would you suggest for 4.4 ghz overclock? I currently have 1.210 and have load 50 degrees?
GOOD OR NOT?

 

[DonkeyOatie]

I don't know that low. That's just Turbo on all cores.

 

[G-star93]

4790k has turbo of 4.4ghz you dont need to change voltage, just enable turbo for all cores that all cores reach 4.4ghz instead of 4.2

What is the stock 4790k voltage so i can set it at that for the time being?

 

[G-star93]

don't know just reset the bios or put voltage back to automatic and find the option that allows all cores for running at max turbo speed.

The stock voltage is a little different for each chip and is set at the factory to ensure that the CPU meets the stated performance requirements. BIOS has a reset option which should restore the factory settings.
