Product overview
Part number M321R8GA0EB2-CCPKF identifies this Samsung 64GB DDR5-6400 ECC registered RDIMM dual rank x4 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 64GB module. Send the current layout and we will map the slots for you.
If the part is wrong for your platform we will say so and suggest the one that is, which is cheaper for both of us than a return.

What you get ordering this from us
Ordered by part number
The order is placed against M321R8GA0EB2-CCPKF, not against a description of it, so there is no room for a substitution you did not agree to.
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 M321R8GA0EB2-CCPKF 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 M321R8GA0EB2-CCPKF 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?
