Product overview
Samsung lists M321R4GA3PB0-CWMXJ as a 32GB DDR5-5600 ECC registered RDIMM dual rank x8 288-Pin Server Memory Module. Population order decides whether you get the full memory bandwidth or a fraction of it, and the rules change between one and two processors. This is a 32GB module. Send the current layout and we will map the slots for you.

What you get ordering this from us
Ordered by part number
M321R4GA3PB0-CWMXJ is what is quoted and M321R4GA3PB0-CWMXJ is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Population mapped for you
Send the current DIMM layout and we return the slot map with the quote, so the modules go in the right order.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
- Is M321R4GA3PB0-CWMXJ genuine and is the warranty intact?
- Yes — new and sealed, with the Samsung warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will M321R4GA3PB0-CWMXJ work in my server?
- Send the server model and a list of the DIMMs already fitted. Rank, voltage and population order all have to agree, and a module that is electrically compatible can still be unsupported in a given slot. We map the population before you order.
- Do you accept purchase orders and quote at volume?
- Yes. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

Specifying a system, not just the part?
Host memory on an AI node is normally sized against accelerator memory, so the model and its working set both fit.
