Product overview
Part number M321RBGA0B40-CWK identifies this Samsung 256GB DDR5 4800MHz CL40 ECC RDIMM Memory. Memory is the part most often ordered wrong — this is DDR5, because rank, voltage and population rules differ per platform and per slot. Give us the server model and the DIMMs already fitted and we will confirm the configuration is supported.
We return an itemised quote within 48 business hours, and we say plainly when a part is constrained rather than quoting a date we cannot hold.

Questions buyers ask about this part
- Is M321RBGA0B40-CWK genuine and is the warranty intact?
- Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
- Will M321RBGA0B40-CWK work in my server?
- Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.

- 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.
