Should mention I have a single Kingston Fury HyperX DDR4 HX421C14FB/16 DIMM installed in A2.
But I can't seem to find a timing that works for the 5600.

Thanks - I thought that may be the problem.
I do have a single 16GB DIMM - tried Slot 1 and in Slot 2.
So - assume I have to change it.
Any advice on specification for the RAM? ]]> Mon, 20 Nov 2023 16:25:16 +0000 https://forum.asrock.com/forum_posts.asp?TID=26993&PID=108334&title=370-fatal1ty-g4-cpu-upgrade-fail#108334 https://forum.asrock.com/forum_posts.asp?TID=26993&PID=108290&title=370-fatal1ty-g4-cpu-upgrade-fail#108290 Author: kerberos_20

if it powercycles, then your ram is not compatible with your new CPU.
try with single stick in A2 slot

btw x370 G4 was very shortly EOL with gaming X as replacement due to ram signaling issues
