Nope, in bios settings they are options, but with IFR extractor it shows that input is numeric from 0 to 65535 with a step of 1 which means thousands of possible inputs. That why it looks weird!!!.
AMIBCP reads the same failsafe 65535 and optimal 0
0 means Auto
5 means 1.400V
6! means Auto again! 
From there everything after 05 means Auto looks like
The voltage looks again 1.4V when I set to 6, but in bios it shows Auto
Tried 06, 07, 08 all are 1.4V actual but shows auto in bios. Should I try changing to 65535?
Unfortunately, I don’t know, but I think “5” is this value.
,…try others options what not works in AMI BCP for better OC
more is think impossible ,…,don’t risk damage 
Thank you really. It was really fun topic to me. I hope I didn’t bother you 
I learnt some stuff. Really useful stuff
