Can't adjust cpu voltage Asus Crosshair VIII Hero 3900X

I just got my new system up and running today and immediately noticed the cpu is 1.478v. I set the cpu voltage to "Manual", but nothing works to adjust the voltage. Up and down arrow keys, -/+ key, number keys nothing works. All of the aforementioned key strokes only enable me to change to "Auto" Manual" or "Offset", but no voltage adjustments.
Latest BIOS.
Am I ******** or do I need the secret AMD password?

Oh I love it, this is hilarious. I thought I'd always be the person that would be stuck like this only to find something simple not working. Glad you sorted now.

lol

I have my 3900X at 1.35v and 4.3 all core so far. It's single core score in R20 is higher than when I tried just using PBO and it occasionally spiked up to 4.6Ghz. So, all core 4.3 seems better than just PBO in single core use. Temps around 70C all core and way under that in single. Will try pushing it further w/o raising the vcore.

4.4Ghz all core stable so far even with a vdroop. In the single core test the 3900X at 4.3Ghz tied my 7700K at 4.8Ghz.
4450 stable so far even with a vdroop of 1.263v
Let's try 4500...
