I wanted to add a further update to this. Thinking I might have a bad CPU, I tried a new replacement and it made no difference, also tried changing the PSU which again made no difference. Next I tried an identical spec replacement TUF Gaming B550-Plus motherboard, this cleared the issue for me, even going back to all the original components. I can now boot cleanly, with Global C-State Control on the default auto and with the memory on the DOCP profile (2 x 8Gb Crucial 3600 C16).
So it seems like I had some kind of fault on the motherboard
The more people I speak to about this board it seems it's a memory issue, DOCP profile just doesn't really work properly, but if you set at timings right using the Ryzen Dram calculator, bump the ram voltage really high, SOC quite high, then slowly back off until you have issues, that seems to fix all the stuttering, random crashes etc.
I know we shouldn't have to do this, as it should work out the box, but this seems to be the main problem. Mine is 100% stable now, even OCed the ram from 3600>3733 and tightened the timing from CL18>CL16
Use the Ryzen DRAM cal, it works, just give it plent of voltage, then slowly back off until it becomes unstable, use memtest to test it.
Also, run the Dram cal on a laptop next to the computer, it makes life alot easier for copying settings.
Hope this helps
