M321R4GA3EB2-CCP Présentation
A Registered DIMM (RDIMM) is a memory module that places a register between the CPU memory controller and the DRAM chips, buffering command and address lines. This buffering reduces electrical loading on the controller, enabling more modules per channel and higher capacities in servers. The broader hierarchy runs: DDR5 SDRAM -> memory module -> RDIMM -> server main memory (system memory -> memory subsystem -> computer hardware). RDIMMs differ from UDIMMs (unbuffered) and LRDIMMs (load-reduced); they are required by virtually all current Intel Xeon and AMD EPYC server platforms.
Key features include DDR5-6400 (PC5-51200R) bandwidth of 51.2 GB/s per module, on-module ECC for enterprise-grade data integrity, dual-rank x8 organization built from twenty 2Gx8 FBGA DDR5 DRAM devices, and 1.1V low-voltage operation that reduces power draw versus DDR4. DDR5 also moves the power management IC (PMIC) onto the module and splits the command/address bus for improved efficiency.
The module is 4Gx72 organized (64-bit data plus 8 bits of ECC) and is JEDEC PC5-51200R compliant. According to distributor memory.net, this module is compliant with specifications for DDR5-6400 Registered DIMM performance in Intel platform systems and is the same module specified at Dell, HP, IBM and other OEMs.
Typical applications include general-purpose rack servers, edge compute nodes, and low-VM-density virtualization hosts, where 32GB per DIMM at 6400 MT/s balances capacity, bandwidth, and cost.
Design consideration: always populate memory channels symmetrically per the server qualified vendor list (QVL); mixing x4 and x8, or single-rank and dual-rank modules, can change supported speed. Verify BIOS-level speed support, as some platforms down-clock DDR5-6400 modules to 5600 or 4800 MT/s depending on population.

Applications typiques
M321R4GA3EB2-CCP convient pour 6 applications: General-Purpose Rack Servers, Virtualization and Cloud Hosts, Edge Compute Nodes, Database and Analytics Servers, OEM Server Rebuilds and Refreshes, High-Performance Computing Clusters.
General-Purpose Rack Servers
General-purpose 1U/2U rack servers based on Intel Xeon 6 or AMD EPYC 9005 processors are the primary home for the M321R4GA3EB2-CCP. Its 32GB capacity at DDR5-6400 (PC5-51200R) provides 51.2 GB/s of per-module bandwidth, and the dual-rank x8 organization improves memory controller utilization at moderate capacities. The module is JEDEC PC5-51200R compliant, so it drops into any channel qualified for DDR5-6400 RDIMM. Per ramquote.com cross-reference, it matches Supermicro MEM-DR532L-SL02-ER64 in X14/H14 platforms. Populating 8-12 channels symmetrically with identical modules maximizes achievable bandwidth; registered ECC operation protects against bit errors in 24/7 enterprise workloads.

Virtualization and Cloud Hosts
Virtualization hosts running VMware ESXi, KVM, or Hyper-V benefit from the M321R4GA3EB2-CCP's balance of capacity and bandwidth. Distributor globalmemorysupply.com positions this module for low-VM-density hosts and general-purpose use. Each 32GB module supports several VMs at DDR5-6400 speeds, and on-module ECC plus DDR5's on-die ECC mechanisms reduce silent data corruption risk in consolidated environments. The 1.1V operation keeps per-DIMM power low, which matters when populating 16-24 DIMMs per node. Memory bandwidth at 6400 MT/s prevents the memory subsystem from starving vCPU scheduling in mixed database and application workloads, and registered buffering allows full channel population without controller overload.
Recommandé
Edge Compute Nodes
Edge compute appliances - compact servers deployed in telecom central offices, retail backrooms, and factory floors - use the M321R4GA3EB2-CCP where DDR5-6400 RDIMM bandwidth is required in a short deployment footprint. Samsung's own positioning (via globalmemorysupply.com) names edge compute as a target workload. The module's JEDEC-standard 288-pin registered interface fits short-depth and single-socket edge platforms based on Intel Xeon E/Xeon 6 or EPYC 8004 series. ECC Registered operation is important in remote, unattended sites where error correction prevents uncorrectable crashes between maintenance windows, and 1.1V operation reduces total system thermal load in constrained enclosures.
Recommandé
Database and Analytics Servers
In-memory database engines (SAP HANA-class, PostgreSQL buffer caches, Redis clusters) and analytics platforms are bandwidth-sensitive, and the M321R4GA3EB2-CCP's 6400 MT/s rate helps feed modern many-core CPUs. A dual-rank 2Rx8 module per channel balances rank interleaving benefits with electrical loading. In servers with 8 or more memory channels, filling channels symmetrically with this module yields up to 400+ GB/s of aggregate bandwidth depending on platform. Registered ECC protects long-running analytics scans from bit errors, and PC5-51200R compliance means the module interoperates with other JEDEC DDR5-6400 RDIMMs - though mixing x4 and x8 widths should be avoided to prevent down-clocking.
Recommandé
OEM Server Rebuilds and Refreshes
System integrators rebuilding Dell PowerEdge, HPE ProLiant, and Lenovo ThinkSystem DDR5 platforms use the M321R4GA3EB2-CCP because, per memory.net, it is the same factory-original module specified at Dell, HP, IBM and other OEMs. Using the OEM-specified Samsung part preserves warranty and QVL conformance during server refresh or RMA replacement. The 32GB DDR5-6400 2Rx8 configuration matches the most common 32GB server line item (PC5-51200R), so a single SKU covers Xeon 6 and EPYC 9005 builds. Distributors such as ServerSupply stock the part new, simplifying procurement for service organizations.
Recommandé
High-Performance Computing Clusters
HPC clusters built on AMD EPYC 9005 Turin (Supermicro H14 generation, per ramquote.com cross-reference) benefit from DDR5-6400 RDIMM bandwidth for memory-bound scientific codes. The M321R4GA3EB2-CCP delivers 51.2 GB/s per module; a fully populated dual-socket EPYC node with 24 channels can exceed 1 TB/s of aggregate memory bandwidth when platforms support 6400 MT/s across all populated DIMMs. The 2Rx8 organization provides the rank interleaving that streaming workloads (CFD, molecular dynamics, FFTs) rely on. ECC Registered operation meets cluster stability requirements for multi-week job runtimes, and JEDEC compliance ensures uniform behavior across mixed-lot deployments.

- DDR5-6400 speed grade at CL52 (vs M321R4GA3EB0-CWM)
Notes de conception
Match rank and width configuration across a memory channel. The M321R4GA3EB2-CCP is 2Rx8; mixing it with 1Rx4 modules such as M321R4GA0EB2-CCP in the same channel can force the memory controller to run all modules at the lowest common supported speed or refuse training. ramquote.com explicitly recommends keeping vendors consistent within a memory bank. Before deploying, verify the module appears on your server OEM's qualified vendor list (QVL) - e.g., Supermicro qualifies it via MEM-DR532L-SL02-ER64 for X14/H14 platforms.
The module operates at 1.1V with an on-module DDR5 PMIC, which regulates the 12V DIMM slot supply down to the DRAM rails. Budget roughly a few watts per module in server power calculations; exact dissipation depends on access patterns and is specified in Samsung's datasheet power tables. When populating all channels (up to 24 DIMMs per dual-socket EPYC node), verify chassis airflow over the DIMM banks - DDR5-6400 RDIMMs run warmer than 4800 MT/s parts, and most server platforms require mandatory DIMM heatsinks and airflow baffles at this speed grade.
BIOS speed support matters more than the module's rated speed. DDR5-6400 (PC5-51200R) is only achieved if the platform's BIOS and memory controller support 6400 MT/s at the populated configuration; some platforms down-clock to 5600 or 4800 MT/s depending on DIMMs per channel and rank count. Check the server's memory speed table before purchase - memory.net notes this module is validated for DDR5-6400 RDIMM performance in Intel platform systems, while EPYC 8004/9004 platforms may run it at lower speeds with heavy population.
