Manual OC 3800X voltage

I have a 3800X that I would like to try manually overclocking.
using MSI x570-a-pro.
I have ran p95 small FFTS, with auto PBO, auto vDroop. I notices the following after 1 hour (hwInfo):

Min 1.231V
Max: 1.262V
Average: 1.25V

I am wanting to try a manual OC.
Before I start, I have a couple questions. What voltage should I start with? Should I stick to 1.231V idle, or after vdroop? Should I try a higher voltage, with a droopy LLC that will hit 1.231 under p95 load, but stay higher than that daily?

Is it safe to do the overclocking in RyzenMaster, and then copy those settings to the bios? I was thinking of leaving voltage to auto in bios, and setting voltage and frequency in RM.

Thanks in advance

I always go for the most droopy llc, so 1.23v max underload. I would also take note of core current and tdc current during the pbo test and make sure your OC is lower than that. Probably 1.2v is my guess.

I think the hype about Zen2's degrading is way overblown with 1.25v+(I've heard of many samples running fine since launch with a 1.35v+). I think some oof the early samples were just bad chips which is why they died, still it's better to play it safe with around 1.2v.
