M321R4GA0EB2-CCP Descripción general
A registered DIMM (RDIMM) is a server-class memory module that buffers the command and address signals through a registering clock driver before they reach the DRAM chips. This buffering reduces electrical loading on the memory controller, enabling higher memory capacities and more DIMMs per channel than unbuffered UDIMMs. RDIMMs sit at the top of the memory-module hierarchy (DRAM -> DDR5 SDRAM -> registered module -> server memory) and are the standard choice for enterprise servers and workstations built on Intel Xeon and AMD EPYC platforms.
Key features of the M321R4GA0EB2-CCP include a 6400 MT/s data rate (PC5-51200 bandwidth class), on-module ECC for single-bit error correction, single-rank x4 organization, and a low 1.1V operating voltage that reduces per-module power draw compared with DDR4 RDIMMs. DDR5 moves the power management onto the module itself via a 12V PMIC, improving signal integrity and power efficiency. The -CCP speed-grade suffix denotes the 6400 Mbps bin within Samsung's DDR5 RDIMM family.
On the technical side, DDR5 doubles the number of independent channels per DIMM to two 32-bit (plus 8-bit ECC) subchannels, banks are expanded to 32, and burst length is 16, all of which improve effective bandwidth and concurrency for virtualized workloads. Single-rank x4 organization keeps memory-controller latency low and leaves rank interleaving headroom when paired with additional modules.
Typical applications include general-purpose enterprise servers, edge compute nodes, and low-VM-density virtualization hosts, where 32GB per module at DDR5-6400 balances capacity, bandwidth, and cost. The module is JEDEC-compliant and validated in platforms from Dell PowerEdge, HPE ProLiant, Lenovo ThinkSystem, and Supermicro.
For design-in, verify the host platform's validated DIMM population rules: DDR5-6400 RDIMMs often derate to lower speeds when all channels are fully populated, and mixed-rank configurations can change supported speeds.

Aplicaciones típicas
M321R4GA0EB2-CCP es adecuado para 6 aplicacións: General-Purpose Enterprise Servers, Edge Compute Nodes, Low-VM-Density Virtualization Hosts, Dell PowerEdge Server Upgrades, HPE ProLiant Server Memory, Supermicro Server Platforms.
General-Purpose Enterprise Servers
The M321R4GA0EB2-CCP is a natural fit for general-purpose enterprise servers built on Intel Xeon and AMD EPYC platforms, where its 32GB capacity per module and DDR5-6400 (PC5-51200) bandwidth deliver a balanced memory-per-dollar profile. As a registered ECC DIMM, it supports the high DIMM counts per channel required in 1U/2U rack servers while the on-die and link ECC protects against single-bit errors that would otherwise crash virtualized workloads. At 1.1V, per-module power stays low, which matters when populating 16-24 slots per node. Install in matched sets per channel to sustain 6400 MT/s; verify derating tables when all slots are filled.
Recomendado
Edge Compute Nodes
Samsung positions this module specifically for edge compute, where nodes are physically compact, thermally constrained, and remotely managed. The 1Rx4 single-rank organization minimizes electrical load and helps maintain DDR5-6400 speeds in densely populated short-depth servers, while 32GB per DIMM allows adequate capacity in as few as 4-8 slots, leaving room for airflow. The 1.1V operating voltage reduces module heat dissipation, easing cooling in sealed or fanless edge enclosures. ECC registered operation is essential for unattended edge sites where a correctable single-bit error must not escalate into an uncorrectable failure requiring a truck roll.
Recomendado
Low-VM-Density Virtualization Hosts
For virtualization hosts running a modest number of VMs, 32GB modules such as the M321R4GA0EB2-CCP let administrators scale memory in 32GB increments without over-provisioning. DDR5's dual 32-bit subchannels and burst length 16 improve concurrency, which benefits hypervisor scheduling and memory-bandwidth-hungry guest workloads. The CL52 latency at 6400 MT/s is the JEDEC-standard timing for this bin, and single-rank x4 configuration keeps controller latency low for latency-sensitive VMs. When capacity needs grow, identical modules can be added per the platform's population rules while preserving registered ECC protection across the full installed base.
Recomendado
Dell PowerEdge Server Upgrades
The M321R4GA0EB2-CCP is listed as compatible with Dell PowerEdge DDR5-generation servers (e.g., PowerEdge 16G/17G platforms using Xeon Scalable). Upgrade paths typically require RDIMMs, which this module provides, along with ECC for Dell's memory-fault-resilience features such as SDDC (Single Device Data Correction), which is most effective with x4 organization DRAM - exactly the 1Rx4 organization of this module. Install modules in Dell's recommended slots (white tabs first) in matched sets of identical part numbers to preserve validated 6400 MT/s operation and full RAS functionality. Verify against Dell's memory population rules before ordering.
Recomendado
HPE ProLiant Server Memory
HPE ProLiant Gen11/Gen12 servers using 4th/5th Gen Xeon or EPYC 9004/9005 processors accept JEDEC DDR5 RDIMMs like the M321R4GA0EB2-CCP. The module's x4 organization complements HPE's advanced memory protection (online spare, mirroring, and Advanced ECC), which leverages x4 DRAM granularity for device-level correction. At DDR5-6400 with CL52 timing and 1.1V, the module supports the bandwidth HPE's memory controllers advertise for this class. HPE validates specific Samsung part numbers in its QVL; distributors list this MPN as ProLiant-compatible, but administrators should confirm supported speed at their target population before fleet-wide rollout.
Recomendado
Supermicro Server Platforms
Supermicro explicitly cross-references the DDR5 RDIMM family (including the 2Rx8 sibling M321R4GA3EB2-CCP) with its own MEM-DR532L-SL02-ER64 SKU on X13/H13, X14/H14, and SuperBlade platforms, confirming Samsung 32GB DDR5-6400 RDIMM compatibility across Intel Xeon 6 and AMD EPYC 9005 (Turin) systems. The M321R4GA0EB2-CCP, as the 1Rx4 equivalent, drops into the same 288-pin slots and suits Supermicro's memory-bandwidth-focused GPU and storage servers where single-rank DIMMs help hold top validated speeds across 16-24 populated slots. Follow Supermicro's memory population tables to balance ranks across channels for optimal performance.

Notas de diseño
DDR5-6400 is the module's maximum rated speed, not a guarantee. Server platforms derate supported memory speed based on the number of populated DIMMs per channel and rank configuration. Before ordering at volume, check your platform's validated memory population table (Dell, HPE, Lenovo, Supermicro all publish QVLs) and confirm the achieved speed at your target population. Mixing the single-rank M321R4GA0EB2-CCP with dual-rank modules in the same system usually forces all channels to the slowest common denominator.
As a registered DIMM, the M321R4GA0EB2-CCP buffers command/address via a registering clock driver, which is what permits long traces and high slot counts. Do not substitute UDIMMs in RDIMM-only server slots - they are electrically incompatible and will not train. The x4 DRAM organization enables Single Device Data Correction (SDDC) on supporting platforms, protecting against an entire x4 device failure; this RAS benefit is lost if you switch to x8-organized modules.
DDR5 modules carry an on-module PMIC fed from the 12V plane, so power delivery and thermal design move partly from the motherboard onto the DIMM itself. At 1.1V operating voltage, per-module dynamic power is lower than DDR4, but ensure server chassis airflow across DIMM slots meets vendor requirements, particularly in 24-slot configurations. Estimated: full-population 8-channel x 2-DPC servers should assume derating to 5600 MT/s or lower unless the platform explicitly validates 6400 MT/s at full load.
