Played bit with the Ryzen Master. Without changing the voltages (1.44v), can push the CPU without issue at 4.125Ghz and run even cinebench to it.
4.150Ghz it goes straight to error 8 and crashes, so aint trying higher than that. Maybe 1-2 cores can take it, since I saw 4.3 yesterday with XFR running, but not all of them.
Voltage accoring to CPUZ are 1.526v at those speeds, all default mind you. Which is high for my liking regardless the predator performing well.
Also what worries me is that becomes generous with the DRAM voltage when that is OCed via the Ryzen Master. Gives to it 1.43v while I know can run 3600Mhz at 1.35.
So time to figure out why cannot force the voltage to it been lower, and fine tune it over the next few days, now I know it's limitations
And then delve into P-States
