Product overview
The Samsung 16GB DDR5 5600MHz ECC RDIMM Memory Module is supplied under part number M321R2GA3PB0-CWMKH. Memory is the part most often ordered wrong, because rank, voltage and population rules differ per platform and per slot. This module is DDR5. Give us the server model and the DIMMs already fitted and we will confirm the configuration is supported.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

Questions buyers ask about this part
Is M321R2GA3PB0-CWMKH 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 M321R2GA3PB0-CWMKH 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. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

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.
