Product: HP Z8 G5 Workstation Desktop PC RCTO Base Model

HP Z8-G5 Win 11 latest BIOS Cannot Boot with NUMA disabled.

With NUMA disabled the boot process will stop during POST with a message that the DIMMs are in the incorrect load configuration.  I have dual processors, two 16 GB DIMMs, factory installed at machine purchase in the correct locations according to the inside cover of the unit.  (The loading rules in the Z8-G5 Service Guide are useless - AND contradict the order spec'd on the unit's cover.) Performance Advisor shows each DIMM in Channel 1 of each CPU.
