Trying to populate HP Z440 workstations with more RAM. Samsung DDR4 registered modules, M393A2G40DB0-CPB are what's in these units now, part numbers on them are shown in Samsung's own documentation. There are lots of Samsung modules out there, but the vast majority have lsightly different part numbers on their labels. There is no documentation I can find that tells what the extra characters at the end of these part numbers might signify.
M393A2G40DB0-CPB (what we have now, 16Mb Registered SDRAM, came with machines)
What are these others? Can you mix and match these "variants" in a single machine's RAM banks?
M393A2G40DB0-CPB0Q
M393A2G40DB0-CPB2Q
M393A2G40DB0-CPB3Q
M393A2G40DB0-CPB0
TIA for your help!
