   when i use pstates 
i set cool and quiet off
c states auto
c6 off
core performance switches off anyway with pstate overclock

i then go to normal overclock page 
and set cpu volts oc
fixed
and auto

this lets the p state control the volts
i also select cpu vcore llc level 2

my volts stay within a hundreth of a volt

e.g at the moment im on 1.325v

it will never go above 1.329

yet on bios version 3.1 for some reason its still auto matically dropping volts on idle down to 0.500 ish without loosing any stability

my pstates
9c
8
24
second set 
9c
8
24
third set 
auto
fourth set disabled

	so i want to overclock my ryzen 1600 using pstate setting my curent setting for pstate pstate0 vid = 9c (3.9ghz) did = 8 Fid = 123750 (as default pstate setting) pstate1 vid = 7c did = 10 fid = 090000 (as default pstate setting) can't remember the hex value for fid mode = OC mode offset vcore = 0.18125 c6 =disable c-state controller = enable core performance boost = disable amd cool n quite = enable up until know this setting are solid stable under prime95 or corona render engine with vcore topping at 1.424 v but when i reboot the pc or starting the pc after shutdown (cold boot), the vcore start to jump to 1.456v(hwinfo, ryzen master, cpu-z). it will back to normal vcore again after i reboot it the second time but the the symptom continue if i restart, the vcore jump to 1.456v again and fix after i reboot it again. how do i fix this issue?or is this ryzen spesific bug?
