Motherboard: Gigabyte X570 AORUS ELITE ATX AM4 Motherboard
CPU: AMD Ryzen 9 3900X 3.8 GHz 12-Core Processor
Ram: Corsair Vengeance LPX 32 GB (2 x 16 GB) DDR4-3200 CL16 Memory

-20 is pretty common for your PBO curve on 5000s

but for the Matisse 3900x zero experience on these older chips

Not sure why you would want to disable automatic power saving features like C&Q and C states or turn off SMT multi-threading but then use the auto PBO for overclocking?

First I would turn the auto features back on. Then download and install Ryzen Master. As @JohWill stated, set a negative value for Curve Optimizer, set your boost clock override (auto OC) to +200, then run Cinebench Multi-core and watch your power limit gauges. Increase PPT, TDC, EDC (in that order) as needed to keep them out of the red.

You don't mention what cooler you have, hope it's a good one.

Yep, if it’s anything like the 5900x it will get up into 160-170watts so a water 240 aio or bigger. Or Assassin air cooler or larger.  I’d skip if it’s a compact itx. 2percent isn’t gonna break you in performance.  My average is 2 percent gain on 8-12 cores and only 1 percent gain on the 6cores.
