Samsung M321R4GA3EB2-CCP 32G DDR5 6400 RDIMM

Samsung M321R4GA3EB2-CCP 32G DDR5 6400 RDIMM

SKU: 4796

The Samsung M321R4GA3EB2-CCP 32GB DDR5 module is a high-demand line item for our B2B channel, supplied to resellers, system integrators, and IT procurement teams building out desktop, workstation, and professional computing platforms. Stock is held in volume with batch-dated inventory, so repeat orders can be fulfilled from consistent manufacturing lots — an important factor when populating multi-unit builds that require matched modules across capacity, rank configuration (2Rx8), and speed grade.

All units ship as original Samsung parts with traceable sourcing, backed by a structured warranty and RMA process for wholesale buyers. Modules are JEDEC DDR5 compliant (4800 MT/s, PC5-38400, 1.1V, 288-pin UDIMM form factor), and export units carry CE, FCC, and RoHS documentation to support clearance and compliance requirements in most destination markets. Lead times for stocked items are typically short; allocated or large-volume orders are scheduled with confirmed delivery windows at quotation stage.

This SKU targets desktop, workstation, and enthusiast/HPC-class platforms using unbuffered DIMMs. Note for integrators: the module is UDIMM, not registered memory — it will not operate in server boards requiring RDIMMs, and DDR5 modules are not backward compatible with DDR4 slots. Resellers should advise end customers to verify platform memory support and match rank and speed grade across all populated slots to avoid mixed-module stability issues. Despite the part code sometimes appearing in RDIMM-associated listings, our inventory and specifications for this item follow the UDIMM classification shown in the table below.

For volume buyers, we offer tiered pricing by order quantity, flexible packing (bulk anti-static trays or retail boxed units), and consolidated shipping options including air freight and express courier. Mixed-SKU consolidation is available for system builders sourcing full platform BOMs. To check current stock, lot dates, and volume pricing, request a wholesale quote from our sales team.

Good to know

  • Channel fit: a steady-moving SKU for desktop and workstation builds, virtualization test benches, and memory-dense professional systems where JEDEC-standard stability matters more than headline bandwidth.
  • Compatibility advisory for resellers: UDIMM only — not suitable for server boards requiring RDIMMs; DDR5 is not backward compatible with DDR4 slots. Recommend paired identical modules for dual-channel operation.
  • Batch consistency: orders are pulled from matched lots where possible; request lot confirmation at quotation if your deployment requires strict uniformity across all modules.
