I believe an "Auto rule" in UEFI is bumping SOC on RAM strap change. Not that UEFI "looks up a table" within CPU/SMU and say "hey set x for me".

I had 2x R7 1700, all same hardware :-

i) if UEFI on default and I changed RAM strap to 2400MHz SOC = ~1.050V for both CPU.

ii) if UEFI on default, thus 2133MHz, SOC measured on ProbeIt point for 1st = ~0.838V 2nd = ~0.893V
