I put in a new Epyc 7443P CPU into a new Asrock Rack mini ITX motherboard.
Board is running BIOS 3.00 and BMC 01.00.00, the only ones available on Asrock rack website.
I have populated all 4 slots with the Micron 64 GB MTA36ASF8G72PZ-3G2E1VI memory, which is on Asrocks Memory QLV list (Picture of the memory module attached).
I found out that one of the sticks is dead (hence one slot appears empty). While troubleshooting it, I realized that all of the memory sticks are showing up as 32GB ?!?
I tried re-seating them couple of times, and as expected, it didnt help.
How do I explain and troubleshootthis?
How is it possible that all 3 sticks show up, but only with half capacity?
Is it some motherboard option I need to enable?
Is there a chance someone swapped stickers and these are actually some random 32GB dimms?
How can i verify the RAM model number from bios or IPMI interface? Asrock’s IPMI is pretty bad as usual, the inventory doesnt show anything, its totally empty
The sticker in the photo you posted looks pretty pristine. I would think it would be difficult to swap stickers without leaving a wrinkle, smudge, some slight crookedness on at least one of the modules… but I guess it’s possible.
You should be able to read the module’s SPD values with the free version of Memtest86. After it boots to the GUI navigate to System Info → View detailed RAM (SPD) info. Should hopefully have a model number listed.
hello
this is not by any mean an eplanation to what is going on on your system.
(i am assuming you have tried every combination possible: 1 stick, nope as per the manual 2 sticks 4 sticks, and swaping the sticks around)
(i am also assuming your cpu and its socket are fine _ no suspicious pin)
I tried to look for the QLV (to double check compatibility) but did not find it… ?
After checking a few things i went to the ftp server and found this:
ftp> ls ROMED4ID*
200 Port command successful

if you feel … adventurous, you could try updating
the file date seem to indicate there is an update to the bios…
Although tbh this does not seem to be a bios revision problem/solution.
to go towards your question i would direct you to a linux bootcd to use some dmi magic:
sudo dmidecode --type 17
this should give you the part number from the module’s POV (to check the conformity of the sticker)
