hi! this 6900xt cant rise vddcgr_gfx more than .850mv , so when stress it at default clocks 2500+ driver crash.
if i put 1500mhz on clock wont crash, because i think 850mv its enought for that core clock.
but doesnt matter what i do, voltage do not go up than 850mv and i dont know where to dig.
i try replace the XDPE from 6800xt with 11 phase config, but the voltage still the same.

why vcore cant rise? any sense line?

update: with furmark at low resolution 250w gpu draw, 1.200v rise. but when load some direct crash...
