I have an MSI B350M Mortar Arctic, I bought a Ryzen 5 1600x running a 240mm rad configuration. However I cannot figure out how to get a stable overclock. Guides I've watched on MSI bios's only tell me to bump up my CPU Frequency (in this case 4000mhz) and leave the CPU core voltage at 1.4v and CPU NB voltage at auto. I have also disabled Core Performance Boost and AMD Cool N' Quiet along with Core C6 state. Can anyone help me figure out what I'm doing wrong on this Mobo? Maybe give some tips on voltages because I dont know what CPU NB voltage is. I know what CPU core voltage is however.
CPU NB voltage if you've not updated your bios will appear in the bios as SoC voltage, raise this to 1.100v, helps with overclocks, dont go any higher than 1.15v.
there is no guarantee that you CPU will hit 4ghz, so if its giving you problems, back off to 3.9ghz and test., leave ram at stock settings for now, worry about getting that up to speed later, CPU mhz is king.
Set CPU LLC to Level 2 to stop vdroop, in the same menu set over voltage protection to enabled, and st over current protection to enabled.
Run a quick test of Cinebench, if you get a black screen its known as Insta-Crash, and you are unstable, you will need to reduce your CPU speed even more, only golden chips hit 4ghz, you will need to test with something more substantial after that like Prime95 or IBT etc, monitor your temps.
I have a video here on when I was using the mortar with an R7 1700, showing my bios settings:
