ASRock Rack has created the first AM4 socket server boards, X470D4U, X470D4U2-2T

Since I’m stuck at the ASRock X570 Taichi’s Thunderbolt 3/USB-C/DP Hotplugging issues I try to advance things at the ASRock Rack X470D4U’s PSU CPU_PROCHOT front.

Let’s make a list which PSUs are OK and which cause trouble!

If I read this thread correctly:

  1. Always causing CPU_PROCHOT (system unusably slow): Seasonic G-450 (tested by @aBav.Normie-Pleb), SS-650KM (tested by @osrk )

  2. Temporarily causing CPU_PROCHOT (CPU_PROCHOT triggers during boot sequence for a short while then reverts back and system operates normally): Seasonic PRIME Ultra Titanium 850W SSR-850TR (tested by @aBav.Normie-Pleb )

  3. Not causing CPU_PROCHOT at all: Seasonic FOCUS Plus Platinum 550 (tested by @aBav.Normie-Pleb )/650 W (tested by @osrk ), Corsair RM Series RM550 550W (tested by @nx2l)

Did I forget anyone? My head is a little spinning from the Thunderbolt-troubleshooting that didn’t lead to progress :-/

Radio silence from ASRock Rack since I gave them feedback that L3.11 is messed up in multiple ways.
Seasonic gave the impression that they are going to investigate further.
