	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 Edited by kerberos_20 - 18 Nov 2023 at 2:47am

	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?

	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.
