Im basically tuning settings in bios to match dmm that way i know if i want 1.00 soc im getting what i request.

Same for vcore.

Both the prime pro and ch6 are almost identical pwm. Likewise both require identical settings.

If you measure pad that is provided on ch6....1.40 socket = 1.45 pad...so even that is off quite a bit...

Socket is all that matters. AMD said 1.40v...im quite sure that is an actual measured voltage by there engineers and not some idiot relying on software in there lab
