M321R2GA3EB0-CWM Übersicht
A Registered DIMM (RDIMM) is a memory module type that adds a register between the memory controller and the DRAM devices. The register buffers address and command signals, reducing electrical loading on the controller and allowing higher-capacity, more densely populated memory subsystems. Within the memory hierarchy, an RDIMM sits in the enterprise server class: DDR5 SDRAM -> registered/buffered module -> memory subsystem for servers and workstations. Unlike unbuffered UDIMMs used in desktops, RDIMMs are required by most server platforms for signal integrity at scale.
Key features of the M321R2GA3EB0-CWM include 5600 MT/s (PC5-44800) data transfer rate, ECC (Error Correcting Code) for single-bit error correction in always-on server environments, and on-module PMIC power management introduced with the DDR5 standard. The x8 DRAM organization with single rank (1Rx8, 2Gx72) keeps memory bus loading low, enabling high-speed operation on dual-socket and single-socket platforms supporting DDR5-5600.
Architecturally, the module uses DDR5 DRAM with 10 FBGA 2Gx8 devices per the manufacturer configuration. DDR5 doubles bank groups versus DDR4, lowers operating voltage from 1.2V to 1.1V, and moves power management onto the module itself, improving granularity and efficiency in dense server chassis. ECC together with registered signaling targets enterprise reliability targets for virtualization and databases.
Typical applications include entry-level virtualization hosts, edge compute nodes, small-scale servers, and workstations certified for RDIMM operation. The module is compatible with platforms from vendors such as Dell and HPE that support DDR5-5600 RDIMMs.
Design consideration: verify your platform explicitly lists PC5-44800 RDIMM support; DDR5-5600 RDIMMs will downclock on platforms limited to lower JEDEC speeds, and mixing ranks or speeds across channels can reduce system bandwidth.

Typische Anwendungen
M321R2GA3EB0-CWM ist geeignet für 6 Anwendungs: Entry-Level Virtualization Servers, Edge Compute Nodes, Small-Business Database Servers, High-Performance Workstations, Data Center Memory Expansion, Network Appliance Memory.
Entry-Level Virtualization Servers
The Samsung M321R2GA3EB0-CWM is well suited to entry-level virtualization hosts because its ECC Registered interface corrects single-bit memory errors that would otherwise crash long-running virtual machines, and its 16GB per-module density allows 128GB or larger pools across 8 DIMM slots. The registered buffer reduces electrical loading on the memory controller at 5600 MT/s, maintaining signal integrity with multiple modules per channel. In a dual-socket Xeon Scalable or EPYC platform, populating all channels with 1Rx8 modules delivers balanced bandwidth for consolidating several VMs per host. The 1.1V operation keeps per-module power low, improving rack density and cooling overhead.
Empfohlen
Edge Compute Nodes
Edge compute appliances benefit from the M321R2GA3EB0-CWM's combination of DDR5-5600 bandwidth and 1.1V efficiency, since edge enclosures often have constrained cooling and power budgets. The 16GB 1Rx8 configuration provides a cost-efficient memory footprint for inference, caching, and protocol translation workloads, while ECC Registered operation ensures unattended reliability in remote sites where physical access is rare. The module's JEDEC-standard 288-pin RDIMM interface drops directly into server-class edge platforms from Dell, HPE, and Supermicro. At 5600 MT/s, it keeps pace with modern accelerator cards' host-memory demands for data preprocessing before local analytics.
Empfohlen
Small-Business Database Servers
Database workloads such as MySQL, PostgreSQL, and small SQL Server instances are memory-latency and capacity sensitive, making the M321R2GA3EB0-CWM a natural fit for small-business database hosts. Its CL46 latency at 5600 MT/s and single-rank organization deliver low, consistent access times for OLTP query patterns, while 16GB per module scales a 2-socket platform to 256GB without populating every slot, preserving upgrade headroom. ECC protects database integrity against cosmic-ray-induced single-bit flips, a documented cause of silent data corruption. The registered interface maintains timing margin when all eight channels are loaded in dense memory configurations.
Empfohlen
High-Performance Workstations
Workstation platforms built on server-class chipsets that accept RDIMMs can use the M321R2GA3EB0-CWM for memory-intensive workloads such as CAD, simulation, and 4K/8K video editing. DDR5-5600 provides roughly 1.5x the peak bandwidth of DDR4-3200 per channel, directly reducing render times and dataset swap stalls. The 16GB capacity per module enables 128GB-class configurations in four slots, sufficient for large assemblies and timeline editing. ECC adds a stability layer that consumer UDIMM platforms lack, valuable for multi-hour render jobs where a memory error would discard progress. Verify the workstation board explicitly lists DDR5 RDIMM support before purchase.
Empfohlen
Data Center Memory Expansion
For data centers expanding existing DDR5 fleets, the M321R2GA3EB0-CWM slots into spare RDIMM sockets to raise per-node memory without replacing the platform. Its PC5-44800 rating matches the native speed of current-generation Xeon Scalable and EPYC 9004-class memory controllers, so no downclocking penalty is incurred. The 1Rx8 organization presents low bus loading, allowing two DIMMs per channel in many platforms for capacity scaling. Samsung's enterprise-grade DRAM and the module's on-module PMIC support the power granularity and telemetry that DDR5 server platforms expose for predictive maintenance, reducing unplanned downtime in virtualized fleets.
Empfohlen
Network Appliance Memory
Network and security appliances - SD-WAN gateways, firewalls, and load balancers built on server-class CPUs - rely on fast memory for flow tables, TLS session state, and packet buffering. The M321R2GA3EB0-CWM's 5600 MT/s rate sustains high packet-per-second workloads where memory bandwidth bounds throughput, and its ECC Registered interface meets the 24/7 uptime requirements of network infrastructure. The 16GB 1Rx8 configuration balances cost against the 64-128GB footprints typical of mid-range appliances. JEDEC-standard RDIMM form factor simplifies second-source procurement across appliance production runs from multiple ODM builds.

Wichtigste Unterscheidungsmerkmale
- Native DDR5-5600 operation on current server platforms (vs. Lower-speed DDR5-4800 RDIMMs)
- Samsung OEM silicon with enterprise qualification trail (vs. NEMIX RAM 16GB DDR5-5600 1Rx8 RDIMM)
- 1Rx8 single-rank organization (vs. 2Rx8 dual-rank 16GB RDIMMs)
Designhinweise
Verify platform memory type before purchase: RDIMMs like the M321R2GA3EB0-CWM will not boot in desktop boards that accept only UDIMMs, and vice versa. Check the server OEM's qualified vendor list (QVL) for approved 16GB DDR5-5600 1Rx8 RDIMM part numbers. On platforms limited to DDR5-4800, the module will operate at the lower JEDEC speed without issue, but mixing 5600 and 4800 modules in one system forces all channels to the slower speed.
For best bandwidth, populate DIMM slots following the platform's channel population order - typically filling one module per channel across all channels before adding a second DIMM per channel. Balanced 1Rx8 population across all eight channels maximizes interleaving and avoids unbalanced memory controllers. Consult the server vendor's population rules for derated speeds when using two DIMMs per channel at 5600 MT/s.
DDR5 RDIMMs include on-module PMICs, so per-module power is locally managed at 1.1V; still, ensure chassis airflow over DIMM slots in dense configurations. Many server platforms expose DIMM temperature telemetry via the sideband I2C bus for predictive throttling. In high-ambient edge enclosures, verify inlet air meets the JEDEC module operating temperature range and avoid stacking fully populated channels directly above hot-running components.
