Which of the Mobo/CPU/Memory is failing?

Hello everyone,


I am writing here as a last hope to sort out problem with my new PC I have built for myself for video editting and gaming.



  • CPU: AMD Ryzen 5 2600x
  • Cooler: AIO CoolerMaster MasterAir 240 -> link
  • Mobo: Msi AM4 B450 mortar -> link
  • Memory: HyperX 16gb (2x8gb) CL16 3200Mhz -> link
  • GPU: Msi RTX 2070 Armor
  • HDD: Crucial MX500 500GB + WD 3,5" 3TB
  • PSU: Corsair RM750x - > link
  • All put into Fractal design meshify C mini with changed fan configuration to improve airlow. 2 front 140mm fans intakes, 1 back 120mm fan exhaust, radiator with 2 120mm fans on top as exhaust.

My temps on CPU are very low, meaning i never get above 60°C after configuring fan curves to balance silence/performance.


First thing after I finished build was update bios, all drivers and then I installed some benchmarking SW to determine if system is stable. It was. From there I was setting everything else to be able to work (installing programs and configuring them to what I am used to from previous PC).


After a week I finally had some time to look at overclocking to get a little bit more performance from my new PC. Long story short, I spend a loads of time reading forums and watching videos (LTT, gamer nexus, jayz, pauls HW) how to overclock, what voltages to put in etc. but I ended up with PC freezing at any level of OC followed by restart and back to default. I coudn't even OC memory to 3200MHz. They are in default confing which I think is 2933MHz 16-18-18-36. I tried to set voltage limit to 1,4V on CPU and set all cores to 4.1GHz in app Ryzen Master and then run stress test there and it seemed OK. But that was probably CPU only stress test. As soon as I try cinebench it freezes.


I tried to Oc one thing at the time to find what is an issue, but it seems like it is a combination of something.


I know I did not provide much detailed information about clocks, voltages and other things, but there is so many that I didn't know what to include. If you reply, please just tell me what additional info you need to find root cause of this issue and I will do my best to provide everything. I would be very glad if someone could help me with this So I know for sure if there is anything wrong in my system and use my warranty if there is.


Thanks to everyone,

@Freezer2802 it's probably a need for more voltage on your CPU if you want higher clocks. it isnt necessarily anything 'failing' more than hitting the silicon limit.

When you OC the cpu, you can't just use 1 stress test to decide it's stable or not.

Games, stress tests, rendering stuff, they all put a different load on the CPU. It will still max it out (usually) but it's not the same thing.

If you want to be sure an OC is stable, you need to do a bunch of tests, if they all pass, only then you can be sure it's stable.

If you put it to 4.1Ghz and test it with 1 tool and works, but crashes with another one, it's unstable.


There have been cases where a stable OC became unstable after a few months-years so that can happen too.

If you want my attention, quote meh! D: or just stick an @samcool55 in your post :3

Thanks everyone for replies.


I tested to set it to 4GHz and that is stable (didn!t touch voltages) but benchmark score is actually lower than what I have on full default.

I tried to set memory to 3200MHz 16-18-18-18-36 and system is not stable even with everything on auto for CPU.


@samcool55 I know that but when it freezes on first stress test, I know immidiatelly it is unstable. Default values are stable in all use cases (rendering video, cinebench, occt, gaming, everything..)


@TH3R34P3R Well I read somewhere that 1,425 should be limit and CPU should easily do 4,2GHz @1,425V. I tried this voltage once but it wasnt stable still.
