Samsung’s M321R4GA0PB2-CCP is a 32GB DDR5 registered module listed at a 6400 MT/s data rate, positioned for server, storage, and virtualization platforms that require registered DIMMs with stable, validated memory configurations. For resellers and system integrators, this SKU is sourced in consistent, date-code-matched batches wherever possible, helping ensure uniformity across multi-unit deployments and repeated project orders.
Please note a discrepancy that procurement teams should resolve before committing purchase orders: the source specification sheet describes the part as a DDR5 UDIMM at 4800 MT/s, while the product designation references RDIMM at 6400. DDR5 modules are not backward compatible with DDR4 platforms, and mixing buffered and unbuffered modules on a single board is not supported. Our sales team can provide datasheet copies, label photos, or sample verification prior to shipment so your BOM remains accurate.

Good to know
- Confirm whether your deployment targets registered server boards or unbuffered desktop/workstation platforms; the product name and source sheet conflict on this point, and we recommend platform QVL verification before ordering.
- The dual-rank 2Rx8 configuration supports higher capacity per channel, useful for memory-constrained server and workstation builds with limited DIMM slots.
- All shipments are accompanied by compliance documentation (CE, FCC, RoHS) suitable for export clearance and resale in overseas markets.
- Stock is held in bulk with periodic restocks; buyers with recurring demand can reserve allocation on scheduled replenishment cycles to stabilize supply for integration projects.
