Hi, i purchased this motherboard but never tried overclock (on ryzen). I overclocked many times before but this motherboard behaves crazily.

I tried going 3,9Ghz with 1,3 vcore, pc booted, passed a 20min stress test with aida 64, then i rebooted, but it got stuck. It wont even show up post (asrock splash screen). I did a reset cmos, tried to boot normally and everything was fine.

Then i tried to overclock again with 3,9Ghz and 1,35 vcore, it is overkill as it has passed a 20min stress test, but it's stuck again without showing post. Reset Cmos and everything is fine.

I bought this motherboard for the overclocking capacity but it seems that i have some weird bugs going on. I dont want to RMA it if i can, is there anything i can do to troubleshoot it?

Didn't really mount that. BTW i solved it:

This motherboard doesn't like direct voltage input, if you encounter the same problems i've encountered before, you can overclock with the offset option:

  • Enter OC tweaker
  • CPU frequency switch to manual
  • Enter your targeted frequency and LEAVE the voltage as is (for me it was 1,235)
  • Go to CPU Vcore Voltage and set it to offset
  • The offset value is determined by the difference of your vcore value target and the cpu voltage in the menu above (for example, i want to reach 1.35, so 1.35-1.235 = 0,115)
  • you're good to go!
LLC: setting up your LLC results in a more stable overclock. Level 3 is good, Level 1 is better, level 1 will increase heavily temperatures, so do it only if you have a liquid cooler and you wanna reach high frequencies. 

1500X
My stable config:
3,9Ghz
1,35v (offset)
Level 3 LLC

My heavily OCed (air cooler though) config
4.0Ghz
1,42v (offset)
Level 1 LLC

the last one is stable (1hr aida) but temps are way to high for my 212 evo, so 3,9gigs is fine
