What are you using to cool your 5900x?
I prefer not to fiddle around in the uEFI other then setting up the basic stuff and memory clocks/timings. Opening up CRT and clicking enable profile if I want to save power and lower temps is the easiest solution.
The latest CTR is the best one I've found. The other ones picked questionable OC's that sometimes weren't even stable in the end. It doesn't take much time for it to do it's thing and give you suggested profiles to test. You still have the option of dropping the clocks and voltages in the profiles anyways.
Here's the CBr23 run I just did. The Hybrid OC works good and one has the option of changing the profile if a higher single core clock is desired.

I'll probably dial back the P1 profile some more in the end. I still have to test and see what effect it has on gaming at 1440p. I'm sure my Time Spy score will drop due to gimping the cpu, but as long as the fps don't drop it shouldn't matter in the end.
