I recently ordered a Supermicro H11SSL-I Motherboard and EPYC 7551 PS7551BDVIHAF that was previously in a HP server. As for memory I have a single stick of Samsung 32GB DDR4-2666 M39A4G43MB1-CTDQ for testing purposes in the DIMM slot that the motherboard manual says to use when you only have one stick.
And of course nothing goes smoothly so I get fan spin but no post out of the VGA.
However I do manage to connect to the IPMI and checking the error log I get no obvious errors other than it’s struggling to adjust the pwm on one of the fans.
According to the POST Code sniffer utility it stops on Code 16. And according to https://www.supermicro.com/manuals/other/AMI_AptioV_BIOS_POST_Codes_for_SM_Motherboards.pdf
I’m guessing it’s this. 0x16 Pre-Memory North Bridge initialization (North Bridge module specific)
Things I’ve tried so far:
Reseat the CPU
Reseat the Memory stick (I dont have any other sticks I can try yet)
I am very confused, am I looking in the wrong place?
Compatibilty issue?
Is this a memory issue or a CPU issue?
Is this HP/AMD CPU Vendor locked? (Though according to the seller it isn’t)
Does the motherboard need both Auxiliary CPU Power as well as main CPU powercables connected?
I probably forgot to mention a lot of things so I will answer questions as best I can.
Help would be much appriciated.
