i5-8600k unstable cpu overclock/crashes no matter what

Hi everyone, I appreciate you for taking the time to contribute to this topic.

I've had spent dozens of hours trying to diagnose and fix the problems that my pc has with the overclock, until now that I am so frustrated and out of hope that I am reaching out to you all that are far more experienced in such field and hoping that with your help I will manage to resolve my issues.

For weeks I’ve had problems with overclocking, no matter what setting I turn on or off/increment or decrement, I am unable to reach a stable overclock that wouldn’t result in system freeze or sometimes a BSOD. (Usually my system just freezes and the only thing I can do is shut down the pc by holding the power button for few secs. Second or so before the system freeze, there’s always this single static electric click noise which is followed by whole system freeze.)

In fact, I am starting to wonder whether there is a hardware issue like PSU failing to supply enough power to CPU or motherboard having some kind of defect that causes this. Unable to investigate this as I do not possess a backup psu, nor motherboard.

My Setup;
CPU: I5-8600k
MOBO: MSI Z370-A Pro
RAM: Kingston Hyperx Predator DDR4 3000MHz
PSU: EVGA 600W W1 80+
GPU: Asus Strix GTX 970
Heatsink: Cooler Master Hyper 212 Evo

Is there anything that I am missing or have configured incorrectly? Anyone with same setup mind sharing their OC? I am open to your suggestions and willing to cooperate with you. Could the PSU be the problem as it is old and classified as low-tier?

With these exact settings I was able to run prime95 for 9 whole hours, the next day the very same settings were failing, resulting in system freezes. I have tried increasing and decreasing Vcore but that doesn't seem to help. Any ideas what could cause this?

I have attached images of my current OC settings.

The PSU in your system is very mediocre if not terrible and should not be used in a system like that so replace ASAP

The problem is not with not enough wattage the problem is the PSU you have

Thank you for clarifying, I had a suspicion that it might be my psu. Would EVGA SuperNOVA 650W G3 or Corsair RM650x be a good replacement? In the nearest future, I am looking forward to upgrading my gpu to something newer, so it would be nice to have a psu that would be able to supply it.

The G3 has a problem with being loud when used in hybrid fan mode and the RMx is quiet but also gets pretty hot and you cant turn off the hybrid fan mode on the RMx
A Seasonic Focus Plus is a better option since its not as loud as the G3 and dont run as hot as the RMx and the hybrid fan mode can be turned off

Thank you for the recommendation. After some research, I decided to go with Seasonic Focus Plus which has pleasing reviews. I was about to go with g3 but then stumbled onto several reports where it has been reported that the psu has problems with over current protection.

On another note your CPU cooler is not all that great either and you should replace that as well
If you want to overclock the cooler is going to be the next problem

What would be good alternatives to my current cooler? Would adding a second fan to my existing cooler be a solution? I know that liquid coolers are damn good at cooling down CPU, as water transfers heat more efficiently but then I would also have to upgrade my case, which I cannot do now, but will definitely do in future.

I don't remember the BSOD code, they were actually pretty rare. My system usually just straight up froze.

UPDATE: I used to take pictures of BSOD screens and then do some research on them trying to diagnose the problem. Here are some of the most recent ones;

(1) Stop code: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
What failed: nvlddmkm.sys

(2) Stop code: IRQL_NOT_LESS_OR_EQUAL

(3) Stop code: SYSTEM_SERVICE_EXCEPTION

All of them are from 16th of August, don't think I had any since then.

The PSU should be replaced no matter what as its not very good and thats the nice way of saying its rubbish
As for the the CPU cooler you have is more than 10 years old so it does not matter the least if you add another fan no matter how good

I have seen a lot of other users recommend the Thermalright Le Grand Macho RT but there is also the Noctua NH-D15S at the same $80 price on Newegg
There is also the Thermalright TRUE Spirit 140 Power at $50 but that cooler is 170mm tall so it will not fit in some cases

Otherwise there is the Noctua NH-U12S and NH-U14S and the Be Quiet Dark Rock series

And last dont buy a CLC cooler they are overhyped overrated overpriced loud and unreliable

Thank you for the wide variety of choice you have provided. Will certainly consider replacing my current cooler in the nearest future, and when I do, I will know where to look first.

My new PSU will arrive on Monday, will update you once I have installed it and runned it for a bit with the overclock.
