Ryzen 7 1700 stuck at 1.5GHz on default settings

I had the exact same issue with a Fatality X370 Professional Gaming...  its likely the way you set the vcore voltage, at least that is what it was for me.. When i set my vcore voltage in both locations (top and down towards the bottom) I got the same as you were getting, like 1550mhz.... 

When I overclocked using the p-states it worked fine..

After overclocking with the p-states,  I went back and set my overclock the conventional way one would overclock...  I used the top frequency and top vcore setting only and it worked fine..  I used 1.350 vcore, the voltage setting on down the page was set to auto but I changed the cpu llc to level4..  It worked as intended...

 I'm running a stable 3.9ghz at 1.35 to 1.376 volts..

 I think i'm going to go back to the p-state overclock though.. I like that better because of the down clock, seems like it used a bit less voltage also..

Na. The ASRock MB is/was most likely good still, depending on if anything shorted out by the TIM connecting a processor pin.

im guessing here as much as anyone

because its a strange fault

but the internet has one option for this stuck speed being thermal throttle

it seems this 1550mhz is ryzens 'pullback' speed hence why i suggested it might be something to do with this mate

could it be a dodgy temp sender on cpu or board

causing thermal throttle when theres no need ?

I tried to downgrade the bios to 2.5 and same problem...
