M321R8GA0PB2-CCP Übersicht
A registered DIMM (RDIMM) is a server-class memory module that buffers address and command signals through a register clock driver (RCD), reducing electrical loading on the memory controller and enabling higher capacities and densities than unbuffered DIMMs. Memory modules sit within the hierarchy of DDR SDRAM - dynamic random access memory - volatile memory - semiconductor memory, and RDIMMs are the standard main-memory choice for enterprise servers and workstations.
Key features include a 64 GB capacity organized as 8Gx72 (including ECC), dual-rank 2Rx4 configuration built from forty 4Gx4 DDR5 DRAMs in FBGA packages, 6400 Mbps data rate, and on-die ECC plus module-level ECC for data integrity. The 1.1 V DDR5 standard voltage reduces power consumption versus DDR4's 1.2 V, and the module is 100% JEDEC DDR5 compliant per distributor CoreWave Labs.
The DDR5 architecture moves power management onto the module with a PMIC, improving supply noise isolation and allowing finer voltage control. The registered interface and dual-rank organization balance bandwidth and capacity for virtualization and in-memory workloads. CL52 latency at 6400 MT/s (PC5-51200) is typical for this speed class.
Typical applications include enterprise servers from Dell, HPE, Lenovo and Supermicro, virtualization hosts, cloud computing nodes, high-performance computing clusters, and memory-intensive databases.
Design considerations: always verify the server platform's qualified memory list (QVL) and populate channels in matched sets per the motherboard manual to achieve full bandwidth; mixing ranks or speeds causes the controller to run all modules at the lowest common speed.

Typische Anwendungen
M321R8GA0PB2-CCP ist geeignet für 6 Anwendungs: Enterprise Server Main Memory, Virtualization and Cloud Hosting, High-Performance Computing Clusters, In-Memory Databases and Analytics, Workstation Memory Upgrades, Edge and Telco Servers.
Enterprise Server Main Memory
The M321R8GA0PB2-CCP is purpose-built as main memory for enterprise servers from Dell, HPE, Lenovo and Supermicro running 5th/4th Gen Intel Xeon or AMD EPYC platforms with DDR5 RDIMM slots. Its 64 GB capacity in a single 288-pin slot lets administrators maximize memory per channel where sockets are limited, and its registered interface (register clock driver) reduces electrical loading so all channels can be fully populated. The 6400 Mbps data rate (PC5-51200R) matches the native speed of current server memory controllers, delivering full bandwidth with CL52 latency. The 1.1 V operation lowers per-module power versus DDR4, reducing data-center cooling load. ECC and on-die error correction protect against soft errors that would otherwise crash virtualized workloads.

Virtualization and Cloud Hosting
Virtualization hosts (VMware ESXi, KVM, Hyper-V) benefit directly from the M321R8GA0PB2-CCP's 64 GB-per-DIMM density: more VMs per socket with fewer modules consuming power and airflow budget. The 6400 Mbps bandwidth sustains memory-hungry hypervisor workloads, while the dual-rank 2Rx4 organization improves memory-level parallelism and effective bandwidth compared with single-rank modules in bandwidth-sensitive deployments. ECC registered operation is mandatory in virtualized infrastructure because a single uncorrected bit flip can corrupt multiple guest workloads sharing the host. The 1.1 V DDR5 supply, combined with the on-module PMIC of the DDR5 architecture, gives cleaner power delivery to the DRAM than DDR4 designs, improving margin at high speeds in dense chassis.
Empfohlen
High-Performance Computing Clusters
HPC nodes running CFD, molecular dynamics and AI training need maximum memory bandwidth and capacity per socket. The M321R8GA0PB2-CCP's 6400 MT/s data rate provides 51.2 GB/s per module (PC5-51200), and populating all eight channels per Xeon/EPYC socket with these RDIMMs yields over 400 GB/s of aggregate bandwidth. The 64 GB dual-rank module offers a strong capacity-per-watt point for memory-bound simulations. JEDEC DDR5 compliance ensures interoperability across cluster vendors, and the -CCP speed bin supports DDR5-6400 platforms. Because rank interleaving improves sustained bandwidth in streaming workloads, the 2Rx4 configuration is preferred over single-rank 1Rx4 modules in many HPC benchmarks, making this module a balanced bandwidth/capacity choice.
Empfohlen
In-Memory Databases and Analytics
In-memory databases such as SAP HANA, Redis Enterprise and Teradata deploy huge DRAM footprints where the M321R8GA0PB2-CCP's 64 GB density reduces module count and thus power draw in memory-bound appliances. Capacity per DIMM directly sets the maximum dataset a fixed-socket server can hold, so 64 GB RDIMMs at 6400 Mbps let analytics platforms keep larger working sets resident and avoid storage round-trips. ECC is non-negotiable for database integrity, and the module's 72-bit path with ECC plus DDR5 on-die ECC provides layered protection. According to distributor data, this JEDEC-standard module fits Dell, HPE and other certified database appliance platforms, simplifying qualification for production database fleets.
Empfohlen
Workstation Memory Upgrades
Professional workstations (HP Z, Dell Precision, Lenovo P-series) with DDR5 RDIMM support use the M321R8GA0PB2-CCP for rendering, simulation and AI-development workloads that exhaust 128-256 GB configurations. One 64 GB module per channel reaches 256 GB in a four-channel board or 512 GB on eight-channel platforms. The 6400 MT/s rating matches workstation memory controllers' overclocked/stock speeds, and CL52 timing is standard for this bin. Dual-rank organization improves multi-threaded application throughput in bandwidth-limited scenarios. As a JEDEC-standard registered module, it is keyed to fit only RDIMM-compatible boards, preventing accidental installation in unbuffered-DIMM consumer desktops, which protects both the module and the platform.
Empfohlen
Edge and Telco Servers
Edge computing and 5G telco appliances (MEC nodes, vRAN servers) are often space- and thermally-constrained, making the M321R8GA0PB2-CCP attractive: 64 GB in one 288-pin slot minimizes module count, and 1.1 V DDR5 operation lowers heat in passively cooled short-depth chassis. vRAN and network-processing workloads are latency- and throughput-sensitive; the module's 6400 Mbps rate and registered, ECC-protected interface deliver deterministic performance with error correction required for carrier-grade uptime targets (99.999%). JEDEC compliance guarantees fit with standard NEBS-style server boards from Dell, HPE and Foxconn ODM platforms commonly used in telco deployments, and PMIC-based on-module power regulation improves noise margin in electrically noisy edge cabinets.

Wichtigste Unterscheidungsmerkmale
- 64 GB per slot maximizes capacity in slot-limited servers (vs. M321R4GA0PB2-CCP (32 GB))
- Original Samsung DRAM with full JEDEC DDR5 compliance (vs. NEMIX RAM 64GB DDR5-6400)
- Latest PB2 build code (vs. M321R8GA0PB1-CCP)
Designhinweise
Install the M321R8GA0PB2-CCP only in DDR5 RDIMM slots - the module keying prevents insertion into UDIMM/SODIMM slots, but never force it into a DDR4 DIMM slot. Follow the server manual's population order (usually white/CPU-farthest slots first) and install matched sets of identical part number and build code per channel to guarantee the memory controller trains all ranks at DDR5-6400. Mixing PB2 and EB2 build codes across channels may still train, but verify your platform QVL permits it.
Estimated: at 1.1 V and typical DDR5-6400 RDIMM module power of roughly 8-12 W under load (per Samsung DDR5 module power estimation guides), a fully populated dual-socket server with 16 modules adds approximately 130-190 W to the system thermal budget. The on-module PMIC regulates the 1.1 V DRAM rail from the 12 V plane, so ensure server PSU headroom and chassis airflow per the platform's thermal design guide.
Do not mix this module with LRDIMMs or UDIMMs in the same server - DDR5 platforms require homogeneous module classes. If the BIOS reports DDR5-4800 or DDR5-5600 instead of 6400, the platform memory controller may not support the -CCP speed bin; update firmware or accept the lower common denominator. Enable ECC scrubbing (patrol scrub) in BIOS for maximum data integrity, and run a full memtest86+ pass before production to catch marginal modules early.
Compliance-Informationen
JEDEC DDR5 compliant per CoreWave Labs. RoHS/REACH status not stated in provided data - Samsung server RDIMMs are typically RoHS compliant, but this must be confirmed on Samsung's official product page.
