Question i7 9700k

[Wurtti]

Hello,how far i can overclock i7 9700k,with be quiet! dark rock 4?

Well, each CPU has its limits and how far you are able to overclock (basically a trial and error thing). The I7 9700k can be OC'd pretty far but it would be pretty pointless Overclocking a already High end CPU. However if you want to do it do it at your own risk! As long as you don't exceed 1.45 volts on the voltage you will be fine, but again this is dependant on your Motherboard and PSU. The more Voltage there is the more heat is produced. I would suggest Atleast 4GHZ at minimum at either 1.3 - 1.4 voltage going up by small numbers then you want to run a Stress test with either Prime95 for an hour or two and see the temperature that is given off. Now a reliable Temp would be 60 C to 70 C at load and 30C to 50C at idle. If you get a blue screen don't worry it doesnt mean your pc is ruined but that means is you will have to reduce the voltage on CPU core.

You are able to Overclock i believe to 4.5ghz but it isnt a 100% garantee, but you want to tweak the CPU CORE voltage each time you try a overclock then if your overclock is a pass at 4ghz then boost the clock speed to 4.1ghz with the same voltage as before and if it succeeds then push it even more until your cpu becomes unstable (blue screen) then you want to increase the voltage. And every time you must take a Stress test and take note of the temperature :I i know, i know it sucks but it is to make sure yor pc doesn't crash. once you get the limit with the good voltage and speed where the Temperature is good for you, Congrats well done finished.

Oh yeah i know you only asked for a specific speed but it is impossible to see unless you know someone with the same specs as you so sorry about that .

Hope this helped .

Hi Wurtti,
We can't now in advance what it can do but at least the stock boost frequency is achievable.

The rule is, reset bios and let EVERYTHING on auto (CPU and RAM)
then stress test and note your CPU voltage and CPU frequency and put them manually in bios. (don't bother with cache and RAM yet)

Then you have two path to follow :

1°/ Better performance :
Bump your multiplier until it's not stable then bump voltage (increments of 0.025-0.05V)
Once you've reach the frequenc you want, lower the voltage as much as you can as long as it remains stable.

2°/ Better thermals
Keep stock frequency and reduce voltage as much as you can until it's not stable.

Edit: Tips stay below 1.38V and 85°C during stress test for daily usage.
