Fits these servers memory support by platform
Confirmed = listed in the vendor's memory documentation for that server. Vendor match = the vendor's own part cross-reference matches this module and its speed is validated for the platform; the module is not taken from that server's memory list. Spec match = this module meets the platform's JEDEC requirements (generation, form factor, validated speed); interchangeability is spec-based, not per-server testing. Confirm against your server's qualified parts list before ordering.

Frequently asked
Is Dell SNPR1WG8C/16G the same module as M391A2G43BB2-CWE?
Yes. Dell resells this Samsung module under part number SNPR1WG8C/16G. The physical module is identical: OEM part numbers are branding, not different hardware.
Can I use a Kingston or Micron module instead?
In most servers, yes: KSM32ES8/16HC (Kingston), KSM32ES8/16ME (Kingston), KSM32ES8/16MF (Kingston) match this module on every key specification (16 GB, DDR4-3200, UDIMM, 1Rx8). Keep vendors consistent within a memory bank, and check your server's qualified parts list for edge cases.
What servers take M391A2G43BB2-CWE?
Dell PowerEdge R250, Dell PowerEdge R350, Dell PowerEdge T150, Dell PowerEdge T350 match it through the vendor's own part cross-reference (e.g. Dell SNPR1WG8C/16G) with a validated speed. Other DDR4 UDIMM platforms generally accept it too; verify against the server's qualified parts list.
