I found with the latest MSI bios I don’t need to touch the LLC setting, just lite load in advanced CPU configuration.
Change it to manual, set AC loadline to 50 to start with, DC loadline to 110-120, then play around with negative offset voltage.
Then change the AC loadline by -10 / +10 until it is stable. Higher AC loadline = higher offset can be applied without too low vdroop, I ended up needing 60 AC LL on my chip for it to not droop to 1.225v or less, so now the voltage curve is 1.25-1.38 with some negative offset applied, and 325 PL stays under 99c in cinebench.
