Undervolting with Precision Boost Overdrive 2 (PBO 2) with Ryzen 3000 series?

I'm glad to see this produced some great results as seen here. Has anyone tried this on Ryzen 3000 series? I have an Aorus Master x570 motherboard with Ryzen 3900x and I do not see any options to do a negative curve.

Unfortunately, PBO2 is only for 5000

Yup. Undervolting 3000 series results in performance drop. However if the undervolting is small it is not a huge performance drop and the reduction of temperature is much more noticeable so it is still worth experimenting. Try to find the sweetspot where the temps are low but performance drop is only marginal in comparison.

Undervolting Zen2 should result in a sizable multicore performance gain particularly on the 3900X/3950X, but it will hurt your single-threaded performance. That's what curve optimizer is designed to fix.
