Whea #19 is a hardware design issue, and has nothing to with the CPUs
I'm sorry but everyone who has it, needs to refund their board ~ or wait 3+ months till PCB designers notice my post (later) and fix this
I am not capable to fix EFI modules and the chance to fix it is low.
It very likely needs a whole new revision of the affected boards | 40+ boards
And if it still is possible to rescue affected boards, it will take at absolute minimum 3+ months.
I expect half a year for it, till they rewrite and repair specific firmware parts of the board
Yet again, no guarantee as this is a design flaw
While you wait or try:
AMD CBS - NBIO - SMU Common Options,
DPM LCLK has to be at 2-1-1-2-2-1-1-2 or 2-1-1-1-2-1-1-1 & DF-States as of 1200 & 1202 still need to be disabled
Thats it, best of luck that your board is not affected
2100 1:1:1 is able to run on stock predicted values @ 36.9ohm proc or lower
2000 FCLK has to work for everyone without touching anything !
