Good to know.
The board doesn't always seem to be able to change all the settings at once. Then when you reboot a second time it actually resets everything.
I know for a fact that doing something like going from a fixed vcore at a lower core/cache multiplier (x47/x44, 1.230v) with something like loadline calibration=high already saved and used (assuming AC and DC Loadline is already at 1.6 mOhms or 160), then going into the BIOS and setting something like this:
5 ghz, x50 / x47
Vcore LLC: Standard
CPU Vcore: Auto
Then saving and exiting, is enough to make the board completely fail to POST (total lockup).
Then when you power off the board with the power switch and power it back on, it boots up like nothing even went wrong to begin with.
I actually got bored and tested the OP's settings.
5 ghz/4.7 ghz, Vcore Normal, DVID +0.030, Vcore LLC: Medium.
AC LL: 40, DC LL: 130 (this is the same as Internal Load Line=Power Saving)
Ran prime95 AVX disabled and saw a 1.236v VR VOUT.
I then loaded my saved 4.7 ghz profile (exact settings as above) and saved and rebooted into the BIOS.
Saw my CPU Vcore was being read as 1.332v (?_?) even though the bios setting was 1.230v
I exited and reentered the BIOS again without saving, and then the vcore was being read correctly as 1.236v.
I suspect the Normal DVID setting was somehow still being applied before the second reboot, but even then that doesn't even compute properly. Because 100mv > 30mv
Far more likely was that the manual voltage (1.230v) was not even being applied at all, and it applied 4.7 ghz with +30mv DVID offset from base VID, with AC/DC Loadline actually changed back to 160/160, which caused a voltage rise compared to ACLL=40 (DC Loadline is not important at all). Then when I rebooted a second time, it actually applied the manual voltage.
Suspect that's the case because I already know that 4.7 ghz with AC LL=160 and CPU Vcore=Auto reads 1.296v in BIOS. And what's 1.296v + 0.030v?
This bug doesn't happen when using Auto voltages (and then going to manual voltages) via saved profiles. Only DVID offsets seem to do this.
