What servers are compatible with the M321R2GA3EB2-CCPKC?

Compatible with Intel Xeon 6th Gen Scalable (Granite Rapids), 5th Gen (Emerald Rapids), AMD 5th Gen EPYC (Turin), 4th Gen (Genoa) processors in 2U/4U rack servers supporting DDR5-6400 RDIMMs. Requires server BIOS/firmware supporting PC5-51200 speeds and 2DPC configurations.

Does this module support Error Correction Code?

Yes, full ECC with on-die ECC plus module-level SECDED (single error correction, double error detection). Includes register buffer parity protection for command/address lines, essential for RAS features in enterprise servers preventing soft errors under heavy workloads.

What is the CAS Latency of this DDR5 module?

CL52 timing at DDR5-6400 speeds, optimized for low-latency server applications. The on-die ECC and PMIC enable stable operation at this frequency while maintaining power efficiency at 1.1V across 1-2 DIMMs per channel configurations.

Is this memory dual-rank or single-rank?

Single-rank x8 (1Rx8) configuration using 16Gb DRAM densities, ideal for maximum DIMM population density per channel. Supports up to 2 DIMMs per channel at full 6400MT/s speed in compatible platforms.

What voltage does the M321R2GA3EB2-CCPKC operate at?

1.10V standard DDR5 operation with integrated Power Management IC (PMIC) for precise voltage regulation and reduced ripple. This lowers overall system power by 20-30% versus DDR4 while enabling higher memory densities.

Can this memory be used in 2DPC configurations?

Yes, qualified for 2 DIMMs Per Channel (2DPC) operation at full DDR5-6400 speed in servers with appropriate memory controllers. Single-rank design minimizes loading for stable multi-DIMM channel population.

Product overview

The Samsung M321R2GA3EB2-CCPKC is a 16GB DDR5 SDRAM Registered DIMM (RDIMM) module designed specifically for enterprise server environments requiring high reliability and performance. Operating at 6400 MT/s (PC5-51200) with a low 1.10V voltage, this single-rank x8 (1Rx8) module delivers enhanced bandwidth and capacity for next-generation server platforms. The ECC functionality ensures data integrity through error detection and correction, critical for mission-critical applications like virtualization, databases, and HPC workloads. With 288-pin DIMM form factor, it supports 2DPC configurations and integrates seamlessly with Intel Xeon and AMD EPYC processors in modern rack servers. The module's registered architecture includes a register buffer to reduce electrical load on the memory controller, enabling stable operation at high speeds across multi-channel configurations. Ideal for data centers upgrading to DDR5, it provides up to 1.5x bandwidth improvement over DDR4 while maintaining enterprise-grade reliability. Bulk packaging supports large-scale deployments with consistent quality control.
