I’m at my parents house messing with the server. I have an Asrock Rack EPYCD8 board that isn’t handling the CPU upgrade from 7351 to 7282 well. Doesn’t post, IPMI shows no signal.
I have to go home on the 3rd of January and there’s a lot more for me to do before I go.
New one doesn’t boot or show anything.
Old one does post except now it’s showing errors on memory slots A C D. These seem to be the slots themselves not the DIMMs.
hmmm, that makes it sound like it might have something to do with the CPU installation method. The retention/cooler screws are properly torqued and everything seems seated correctly?
you get no graphics output with a vendor locked EPYC
cannot get into the UEFI from the terminal
can cycle the num lock for a brief period then it goes unresponsive in whatever state it was last when it stopped
IPMI still functions on both Gigabyte and Supermicro boards
suspect dead or vendor locked
Reseat CPU
clear CMOS
reset all settings in UEFI and IPMI (reflash when you can)
Reseat RAM DIMMs
I never recommend this unless mission critical to prod.
What OS?
Windows will flip shit if the machine has set boot attempt flag but failed boot 3 times
That’s typically a MoBo memory controller compatibility issue not CPU
I’d say it’s very locked but you said half of the CPU’s from the same vendor were working?
So I’d bet 1 worked, 1 was dead (not locked)
That kinda stuff happens when shipping used hardware.
Sucks, but it’s almost as if the silicon becomes MORE brittle and susceptible to breakage when used and mishandled.
