You can try flashing back to an older BIOS then flashback again to the latest, just remember to clear CMOS before flashing a BIOS.
Using the settings I have posted will result in the values you see in the attached image using Windows 8.1.
I never paid attention to the CPU current draw before. So my observation now is very speculative, but here is what I observe (big desktop screenshot).
So, under the full load the CPU voltage goes down to 1.275V-1.288V (occasionally - up to 1.3V), but CPU current goes up.
And looking at CPU power draw chart, it looks like the CPU has kind of a power limit at about 130W - it never goes above.
And the same chart shows that CPU power draw in Windows desktop mode is around ±14W, which seems to be OK.
we figured out that the Ryzen Balanced power plan defaults at 90% for Minimum processor state.
After I changed it to 5%, the CPU clocks multiplier started jumping from x20 to x40, sometimes it is x22 for a fraction of a second.
But the voltage is still 1.35V at idle.
Could DRAM configuration cause this effect, as on previous BIOS'es I entered only the timings and SOC voltage (green rectangles on DRAM calculator screenshot), leaving everything else on "auto", and now I entered additional settings (blue rectangles).

Yep. I do clear CMOS prior to every BIOS flashing. And did it prior to 7002. Maybe I will try to re-flash, if I'll have the time. But I suspect that soon we should get an another BIOS update as a lot of people had issues with 7002.
