Samsung M321R8GA0PB2-CCP 64GB DDR5 RDIMM Memory

The Samsung M321R8GA0PB2-CCP is a high-performance 64GB DDR5 Registered DIMM (RDIMM) memory module, designed for advanced server and workstation applications. Offering a blazing-fast 6400MT/s speed, this PC5-51200 memory module ensures efficient data processing, improved bandwidth, and superior stability. Engineered with ECC (Error Correction Code) and a dual-rank x4 configuration, it enhances data integrity and reliability, making it a robust solution for enterprise computing environments.

Advanced DDR5 SDRAM Architecture

This module leverages M321R8GA0PB2-CCP DDR5 SDRAM technology to provide higher memory density and improved power efficiency. Operating at PC5-51200 standards, it supports faster access to large datasets while maintaining consistent performance across demanding environments.

288-Pin RDIMM Standard

This memory module adheres to the industry-standard 288-pin RDIMM form factor, ensuring compatibility with a wide range of DDR5-capable server motherboards. The standardized design allows seamless integration into existing enterprise systems.

Capacity:64GB 6400MT/s 

With a substantial M321R8GA0PB2-CCP 64GB capacity per module, this RDIMM allows for the creation of high-density memory configurations, reducing the total number of modules needed to achieve large memory pools (e.g., 512GB across 8 slots). The 6400 Mega transfers per second (MT/s) data rate, marketed as 6400MB/s per data pin, defines the raw speed of the interface. This translates into a theoretical peak bandwidth of approximately 51.2 GB/s per module in a standard 64-bit channel (calculated as 6400 MT/s * 8 bytes / 1024). This bandwidth is critical for bandwidth-hungry applications like in-memory databases (e.g., SAP HANA), scientific simulations, and high-frequency trading platforms.

PC5-51200: The Industry Designation

The PC5-51200 label is the JEDEC module designation. It directly correlates to the bandwidth: 51200 MB/s (or 51.2 GB/s) of peak transfer rate. This standardized naming allows for quick cross-referencing and compatibility verification against motherboard and system vendor Qualified Vendor Lists (QVLs).

ECC and Registered Design

This module integrates two critical server-grade technologies: Error-Correcting Code (ECC) and a Registered (Buffered) design. ECC detects and corrects single-bit memory errors on-the-fly, preventing data corruption and silent system crashes—a non-negotiable feature for financial, medical, and research computing. The Register (or RCD - Registering Clock Driver) acts as a buffer for address and command signals, reducing the electrical load on the system memory controller. This enables the population of more memory modules per channel without signal degradation, supporting higher total system memory capacities.

Enterprise Servers and Data Centers

In enterprise-class servers, this Samsung M321R8GA0PB2-CCP DDR5 64GB module enables faster virtual machine provisioning, quicker database queries, and smoother cloud workload migration. For data centers requiring high uptime and optimal resource utilization, the ECC and registered features ensure the memory remains stable even at peak operational demand.

Reliability

Samsung rigorously tests every memory module to meet stringent quality control standards. The M321R8GA0PB2-CCP undergoes multiple phases of validation, including burn-in testing, temperature cycling, and compatibility testing with leading server platforms. This robust QA process ensures each module delivers the reliability and stability enterprises depend on.

Compatibility

The Samsung M321R8GA0PB2-CCP DDR5 RDIMM is compatible with server motherboards that support DDR5 ECC Registered modules. It’s essential to verify BIOS and chipset support for DDR5 and ECC configurations before deployment. As a JEDEC-compliant module, the M321R8GA0PB2-CCP ensures broad compatibility with DDR5-capable platforms. However, users must verify that their server motherboard supports ECC Registered DDR5 modules and the PC5-51200 standard to ensure full functionality.
