Samsung M321R4GA3EB2-CWM 32G DDR5 5600 RDIMM
The Samsung M321R4GA3EB2-CWM is a 32GB DDR5-5600 ECC Registered DIMM (RDIMM) built for enterprise servers, cloud computing platforms, and data center workloads that run around the clock. It suits buyers provisioning virtualization hosts, database or cache tiers, and high-density compute nodes that benefit from DDR5’s higher transfer rate and improved power efficiency. As a registered module, it is intended for server platforms with RDIMM support only — it will not operate alongside desktop UDIMMs or DDR4-generation memory.

Good to know
- Compatibility check first: confirm your platform explicitly supports DDR5 RDIMMs at 5600 MT/s. DDR5 RDIMMs are mechanically and electrically incompatible with DDR4 (288-pin vs. 288-pin DDR4 with different keying) and must not be mixed with non-registered or DDR4 modules in the same system.
- Within Samsung’s DDR5 RDIMM lineup, this module sits at the 5600 MT/s performance tier with a 2Rx8 dual-rank configuration, a common choice for balanced capacity-per-DIMM and channel population in dual-socket server deployments. Populate memory channels per your server vendor’s guidelines for optimal bandwidth.
- Buying tip: for multi-DIMM builds, order modules with identical part number, rank configuration, and revision to avoid training issues and simplify mixed-vendor risk assessment — and verify BIOS/memory reference code support on your specific board before volume procurement.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
