PSA C7H Peeps
SB voltage on [Auto] IMO seems crazy excessive on UEFI 0601.
My build was uneventful up til posting and using UEFI.
I flashbacked UEFI 0601 prior to 1st powerup, removed power from board, then did clear CMOS. I then powered up, went to do screen shot of Main page and CPU page, rig rebooted
. I tried again and it rebooted
. I stopped taking screen shots via F12.
Checked UEFI and found SB voltage readout at 1.094V, applied a DMM to ProbeIt point and it read back as 1.115V
. A manual setting of 1V yielded in 1.064/5V, same as what my C6H would be when set at 1.05V or [Auto] in UEFI and when measured at ProbeIt point.
SOC was read lower in UEFI than Ryzen Gen 1, using DMM on ProbeIt it was ~0.800V. Near enough 0.075V-0.125V lower than several Ryzen Gen 1 CPUs I used on C6H. So SOC [Auto] was as it should be.
RAM [Auto] was 1.202V on ProbeIt point, all good.
PLL [Auto] I never measured, but 1.8V manually set was read back via DMM on ProbeIt point as 1.8V steady as it was on my C6H.
