Product overview
Samsung lists M321R8GA0BB0-CQKDS as a 64GB DDR5-4800 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.

Ordered by part number

Questions buyers ask about this part
- Is M321R8GA0BB0-CQKDS genuine and is the warranty intact?
- Yes. It ships new in Samsung packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will M321R8GA0BB0-CQKDS 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 — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

Specifying a system, not just the part?
