The Samsung M321R4GA3EB0-CWM is a 32GB DDR5 ECC Registered DIMM (RDIMM) rated at 5600 MT/s, a core stocking item for resellers, system integrators, and IT procurement teams building out enterprise servers, virtualization clusters, and cloud infrastructure. Its 2Rx8 dual-rank design enables high channel density on DDR5 server platforms, while the 1.1V operating voltage helps control thermal output in high-density chassis—a key consideration for rack-scale deployments. We supply this SKU in consistent, single-batch lots with date-code matching available on request, making it suitable for large rollouts where module uniformity matters. Note that DDR5 RDIMMs are not backward compatible with DDR4 platforms—buyers should confirm platform memory generation and vendor QVL before placing volume orders.

Sourcing & Deployment Notes for B2B Buyers
- RDIMMs with ECC are designed for registered server memory channels only; they will not operate in unbuffered desktop slots and must not be combined with DDR4 or non-registered DDR5 modules within the same channel—advise your technical customers accordingly.
- With 5600 MT/s, CL46 timing, and a 2Rx8 layout, this module targets the upper range of DDR5 RDIMM performance, well suited to virtualization hosts and cache-tier workloads; note that the bus may downclock on platforms whose memory controllers support lower rates.
- For channel population, modules should be installed in matched sets (identical capacity, rank, and speed) following the server vendor’s population guide to achieve full multi-channel bandwidth and reliable training at 5600 MT/s—we can supply matched-set packing for volume projects.
- Stock is held on a rolling basis with batch consistency maintained for repeat orders; all units ship with full manufacturer warranty support and a structured RMA process for resellers.
- All shipments comply with applicable CE, FCC, and RoHS requirements, with export documentation provided for overseas buyers.
Wholesale & Procurement Notes
- MOQ is negotiable depending on stock position and project scale.
