Subject: would high profile cdimms ment to be used in a 4U server be able to also used in a 2U server?
Hello
Ddimms made for U4 Power10 systems are not compatible with 2U systems (also true the other way ).
Usually, system will unconfigure resource during boot time as it is not the attended CCIN (CCIN looks like 4 digit feature code, but it is the hardware reference that firmware will check to make sure supported parts are installed).
By the way, you void your waranty by modifiying the memory feature and took the risk of burning your CPU memory controler too, since memory must be handled with extreme care due to static electricity sensitivity (ESD prevention with wrist and ESD mat, and 5 sec ESD discharge in the memory ESD backet before memory replug).
Best regards.

I have removed it and compared them
Tested out if your remove those plastic guides from the dimm and plugged them in
Looks like there is some kind of mechanism that makes the server deconfigures the
Cdimm. So was thinking of just removing the high profile ram's plastic part by cutting it off
I can find some low profile ones but like they are too expensive

Are you able to remove a CDIMM from your S822 and compare? Is there a Short CDIMM bracket attached to the S822 DIMM?
Of course this will not be officially supported by IBM, even if it would physcally fit. (Assuming 16, 32 or 64GB CDIMM).
Best course of action would be to organize some kind trade in with an IBM reseller or even request a qoutation from IBM GARS for the same.
