Can i overclock on asus prime a320m-a?

Solution
Normally, no. You can try Ryzen Master. I have OC'ed FX CPUs with its predecessor (AMD Overdrive) when the board's BIOS didn't have any OC'ing options.
Have you entered BIOS to see what it has available?
hey it has everything but no core ratio to overclock my cpu and in ryzen master it wont change anything i put it at 3.9ghz and the voltage at 1.35 and when reboot nothing happens stay at 3.6 ghz
 


OK. Then it looks like AMD covered all their bases and made sure unlocking the multi is out, even in RM. Sorry. Have you tried increasing the base clock in BIOS, if that's available? Might get a few hundred MHz more that way. But you'll have to go with a 350/450 or 370/470 board to unlock the multi.
