The Samsung M321RAJA0MB2-CCP is a 128GB DDR5 ECC Registered DIMM rated at 6400 MT/s, supplied through our B2B channel for resellers, system integrators and IT procurement teams provisioning DDR5-class server platforms. Typical deployment scenarios include virtualization hosts, cloud node builds, AI training clusters and HPC systems, where the registered design reduces electrical load per channel and supports dense per-channel capacity. Note that this is a DDR5 RDIMM only: it is not backward compatible with DDR4 boards and must not be mixed with other memory types in the same platform. Integrators should verify the platform’s qualified memory list (QVL) and BIOS support prior to volume ordering.
Stock is maintained in batch-consistent lots so that multi-unit orders ship from the same manufacturing batch, minimizing firmware and SPD variance across a deployment. Each module is factory-sealed with original labeling, and serialization records are retained to support warranty and RMA processing. Standard warranty coverage applies, with RMA requests handled through our wholesale support channel.
For resellers, this SKU is well suited as a recurring stock item for DDR5 server builds; for integrators, we recommend ordering matched sets and populating memory channels symmetrically per the motherboard manual to achieve rated bandwidth. All shipments are export-ready with CE, FCC and RoHS compliance documentation available on request, and typical lead times are confirmed at quotation.

Platform & Deployment Notes
- DDR5 RDIMM only: compatible with DDR5-capable server platforms (recent Intel Xeon SP or AMD EPYC generations). Will not fit or function in DDR4 systems; mixing generations or unbuffered modules within the same channel population is unsupported.
- The 6400 MT/s grade combined with the 128GB 2Rx4 configuration places this module in the high-capacity, high-bandwidth tier of Samsung’s DDR5 RDIMM family — a dense memory baseline for virtualization hosts and memory tiers feeding GPU-based AI training nodes.
- Ordering guidance for integrators: procure modules in matched sets, populate channels symmetrically per the motherboard manual, and confirm QVL listing for the CCP revision before large-volume rollout.
