Brand new rig on msi meg x870E godlike.

This scared me since I expected to get around 2450 cinabench score but Im 200 behind with this power draw.

Did some digging and changed stuff in bios: Pbo enabled +100 PB overdrive PBO Control: motherboard

This changed nothing really. Oh expo 1 is also on. 2×32gb 6000 CL 26 kit.

Then set undervolt: CO: per core. 7 cores minus 15 core 8 0 (Minus 20 instead of 15 caused a crash) Curve shaper is -10 on all but minimum and low.

This made my cpu run a bit cooler and lost 0 performance.

I think the issue is the pbo control. When set it to motherboard or amd default it only plays around 190-200. While I still have thermal headroom as I am yet to hit 80°

I read a megathread on this issue... could it be that manual pbo control is the answer? What settings would you guys consider safe? I dont want to hit absolute max temps, I only want the cpu to perform as advertised at a stable 230w under full load.

I want the cpu to be able to draw at least 230w if that's safe, but I also like the undervolting thing it has going on, if possible I wouldn't want to abandon that. I know this oc/uv is tame but I am a first timer + I want it to be very stable long term as this is my main pc so pls cut me some slack.
