EDC set for manual overclocking

Well I've been playing around with my AMD Ryzen 9 3950X to see where I can get it stable at a low enough vcore to minimize load temperatures. As things stand my processor is perfectly stable 4.2ghz using 1.1875vcore. My last test running the full blender benchmark showed that 4.233ghz is stable at 1.2125vcore. Now my question is what should the EDC be, what is the maximum limit for EDC with these processors. My reason for asking is I noticed when I set EDC to 200 amps it would lock at 200 amps almost instantly when running an all core benchmark. I changed it in the bios to 320amps just to see where it would stablelise and when running the Blender benchmark it would climb all the way up to 272 amps. Now TDC would be around 120 to 140 amps during the run but I'll post a screen shot later to show the real values.

CPU temps is just over 80C and VRM is hovering around 46 sometimes climbing to 49 or even over 50c depending on ambient as it is summer this side.

I wondering same thing, when put edc 200 vcore go like 1.45-1.50 all core benchmarck. but its rock stable.

Interestingly if I were to set the EDC to 200 to limit it there the performance seem to be the same.
