i5 8600k Overclocking

[BlazingBlazey]

Hello everyone, I'm a bit of a noob to overclocking, and I recently purchased an i5 8600k and paired it with an AsRock Z370 Pro4. I have watched some videos about overclocking and can't seem to get the hang of it, and don't know my ideal voltage to GHz for the i5 8600k on the Z370 Pro4. My CPU Cooler is a CoolerMaster Hyper212 Evo, so I do not know the optimal GHz to overclock to that wont put me over 70C, but the voltage is throwing me off aswell, can anyone assist me? Thank you!

for a 8600k, try 1.3v 4.7 to start

I feel like that would be unstable because it'll cause too much heat

1.3v 4.7 shouldn't be that hot on a 8600k, unless you are using stock cooler or something

Yeah I tried tinkering with it, and I put it to 1.3v and 4.5GHz, and ran Battlefield 5 and got about 80C on the processor

That hyper evo is more then enough to handle pretty much any OC.  Of course you raise voltage things get hot, but this is why the Evo is one of the most popular and effective cooling solution.  Just keep a eye out for temps.  On a stress test like Aida stability test as long as your load temps are in the 70's c your fine.

That is simply not true. Coolermaster's own TDP specification for the Hyper 212 is 150W, but it is probably closer to 125W in reality.

 

The 8600k has a rated TDP of 95W, but this is calculated at the base frequency of 3.6Ghz. At stock turbo speeds, it will draw up to 120W, which is barely within the capabilities of the Hyper 212.

 

With this cooler, OP should leave it at stock and call it a day. With some tweaking, 4.5Ghz at 1.25V may be possible, but 1.25V is probably the limit.

As long as the fans are set to blast you can overclock just fine with the Evo.

My 8086k can handle 4.6 all core on my 212 evo so it would be absolutely fine.

Agreed, the 8086k is a toasty chip, being a binned 8700k.. If the 212 EVO can handle a toasty chip like the 8086k, then it can handle the 8600k. @BlazingBlazey, you should really try to see how it goes though. If you want to make sure your voltages aren't too high, you can undervolt and then overclock.

What voltage do you need for 4.6Ghz? Is it at or around 1.25V? My post was in response to @Turtle Rig's claim that the Hyper 212 can "handle pretty much any OC", which is false. It will certainly not be able to do 5Ghz at ~1.35V and probably not 4.8Ghz at ~1.3V.

 

I said that 1.25V is probably the limit for this cooler, since OP is already hitting 80°C in a game at 1.3V. OP also indicated a desire to keep his gaming temperatures below 70°C, so my recommendation of either stock, or a 1.25V limit is in line with OP's stated goals.

I have many friends with different coolers,, and I know for fact they overclocked at 1.4v with evo and it handled it.  Don't talk unless you have experience...….  Evo will overclock just as well as a liquid cooling,,, and if the fans are fast and your side case door is open your OC will become reality.  Ive used a Evo in the past to get the same overclock that you see now on my sig.  So relax my friend,, Evo or Noctua can handle it. period

My i5 8600k can handle 5,0GHz on all cores at 1,35V.

Cooled with Dark Rock 3, it will stay under 85°C at all times, except FPU AIDA test will make it go to 92°C.

I have owned a Hyper 212, and I am speaking from experience. If you have a different experience, then great, but a claim that a Hyper 212 can handle 1.4V is just not grounded in reality. It may technically "work", but your temperatures will not be under control. Can you show me any evidence that a Hyper 212 can keep a 8600k/8700k from thermal throttling in Prime95 at 1.35V or above? There is plenty of empirical evidence from numerous tech channels that you need a big air cooler or a 240mm+ AIO to be able to run 1.35V. This is also backed up with my own experience. I hit peak temperatures of 90°C at 1.35V with my 8700k and a big air cooler on AVX workloads.

 

I am not disagreeing with you for the sake of disagreement. I am not saying that a Hyper 212 is a bad cooler. I am also not saying that you need a massive air cooler or water cooling in order to overclock. You made an unqualified claim about the Hyper 212 that is objectively untrue, and I just pointed that out. If you want to achieve maximum overclocks, this is not the cooler to do it with. And if you want temperatures below 70°C like OP stated, then you either stick to stock or be content with a modest overclock.
