I can't solve an issue with my TR 1950x. I've got the cpu in a custom loop and I run it in a slight OC state via Ryzen Master, @ 3.8 Ghz and 1.23v. At 100% usage however HWINFO reports, thermal throttling, and the CPU throttles down for a brief moment to like 0.8v and then back again to the 1.23v. However the Tdie temps are under control, I still get the HTC and Prochot EXT to show up.
I attached two snapshots, one in which it is not throttling and chugging along and the other with throttling. On the far right column you can see the average over >12h of constant 100% usage.
Can anyone make any sense of this?
