Ryzen 7 1700 stuck at 2.7 GHz after attempting to use Ryzen Master

My CPU is stuck at 2.7 GHz after trying Ryzen Master. What I've done is I increased the clock speed some in Ryzen Master and hit Apply. It requested a reboot, I agreed. Now I've got 1.3 V and 3600 MHz in BIOS (fixed 36 multiplier), but only 2700 in Windows and voltage is floating around the default values, nowhere near my requested 1.3 V. Tried uninstalling Ryzen Master, reinstalling, moving the clock slider some more - no dice. How can this be fixed?
