SPecs:
Motherboard: GIgabyte z170x gaming 3
CPU: i5-6600k
Cooler: COOLAIRMASTER 212x (better version of the evo)
Powersupply: Rosewell photon 550 Gold+

GPU: MSI GTX 960 4G

So I have followed some youtube tutorials on how to OC my CPU and GPU but when I play games my pc freezes. Im not sure if it my GPU OC or my CPU OC. I have checked temps and did stress test and check temps when Im playing and it doesnt seem to be an issue on why it freezes

Current OC:
cpu: 4.4 ghZ
vCORE: 1.33

Gpu OC : https://gyazo.com/92fd3ca36489f3b7bb7cd1aadecd46eb
108 max power
+150 core clock


Im just trying to get the best preformance for what I paid for so I can have better twitch streams and FPS when I play.
What is the best OC on both i can do with my build?

Solution
Reduce your GPU overclock to +100mhz.

That voltage is rather high for 4.4GHz, isn't it stable at lower voltages? You're gonna be producing a lot of heat. Dial the clock back to 4.2GHz and see the minimum stable Voltage.
 

Well what voltage should I use for a 4.4 ghz OC. Tutorials said as long as it is under 1.4v it should fine.

What do you think is the main reason my pc is freezing when im playing?
 


Around 1.4 is considered a max for water cooling, not air cooling. It's not about what voltage you should use, it's about what's stable, and that's different for every CPU.

I think it's probably the GPU's fault. Unstable overclocks generally result in freezing.


There is no 'best overclock' you can have for your build. My i5 6600k can only go to 4.5GHz without crashing, but someone elses might go to 4.6, or further.

This is because of imperfections in the Silicon die during manufacture.
 
the best way to find out which one is causing freezing is to do one at a time, clock the cpu first and leave graphics card standard to find its potential.
and the standard cpu followed by boosting your gpu.
when your happy with both boost both together if you then have an issue do a check on your power supply to make sure its not dipping
 


Ok so lets say I were to do a 4.2ghz OC what should I put my voltage at.

And what should my I do for a GPU OC on my 960 to get better fps and preformance that is stable

I just told you mate. I can't tell you what your voltages need to be, it's different for every CPU. Start off at 1.2 VCore, and increase in 0.025 increments till it's not crashing while stress testing.

Put GPU at +100mhz, if it still crashes lower to 50, then 0.
If it still crashes at 0 then your GPU isn't the problem.

My 1060 can only do +100mhz, any more and it will crash.
 
Solution


So I set the overclock to 4.2ghz and 1.2 voltage. Everything looked fine when I did a stress test for 5 minutes. does that mean I should keep the voltage at 1.2

Stress testing should be done for HOURS, not minutes.
Your CPU might be fine for 5 minutes, but it might not in an hour or less.

It's recommended you stress test for a minimum of 2 hours.
 

Yeah but do you think 1.2 is too low for a 4.2 oc?
 


Nope, my i5 6600k does 4.1GHz at 1.60VCore.
