3600 or higher.

Some friend in a small shop ran my PC on some company-owned software and my PC is neat, it has no problem what so ever. The weird thing is that my PC still experience the "glitches"... Don't know what to do. Thanks for all the help @HunterAP Really appreciated.

I can't seem to find anything online of the menus in your specific BIOS menus, so unfortunately you'll have to manually go through every option in the BIOS.
If it's not there then maybe someone else can point you in the right direction.

If you have the manual for the mobo, see if it points you to where it's located in the BIOS.
Otherwise you'll have to go through pretty much every option. I'd keep searching in the "Peripherals" tab.

Went to Peripherals -> AMD CBS -> NBIO Common Options -> and... There's only cTDP Control, Processor Temperature Control and Mode0

It seems like a manual overclock @ 3.7GHz, 1.35V allows the ram to clock at 3200MHz... I game-test my PC for 1 hour up to now, seems like it's working...
Tried 3.9GHz w/ 1.4V, even though my PC gained much performance, it became much more unstable.
 
Been playing for 3 hours straight and my PC seems much more stable than before, I will let you know if something ever happens.

I recently ran into a similar issue with my R7 2700X on an x470 board, my fix was to enable Precision Boost in the BIOS and remove any manual overclocking, then in Ryzen Master I set the Control Mode to "Auto" and then manually entered 1600 in the Memory Control section (DDR is basically 2x the speed you set, so 1600 x 2 = 3200). I rebooted and my 2700x is now auto-overclocking itself to the highest it can (at least based on the Precision Boost algorithm) and my memory successfully hits 3200MHz.

Prior to this, my memory also caused system instability and BSOD's when I manually set the memory speed to 3200MHz through either the memory speed multiplier or the XMP profile presets.
