Samsung M393T1K66AZA-CE6Q00827 8GB 2Rx4 PC2-5300P DDR2-667 ECC Registered RDIMM

The Samsung M393T1K66AZA-CE6Q00827 is an 8 GB DDR2-667 Registered DIMM (RDIMM) designed for enterprise servers and high-reliability computing platforms from the DDR2 generation. It operates at 667 MHz (PC2-5300 / PC2-5300P) with a standard voltage of 1.8 V, providing stable and proven performance in older server architectures still widely used in many data centers and legacy systems.This module features a dual-rank (2Rx4) organization with x4 DRAM chips, offering good memory density and efficient bandwidth utilization for typical server workloads of its era. Registered buffering significantly reduces the electrical load on the memory controller and address lines, enabling stable operation with multiple DIMMs per channel and supporting larger total memory configurations. ECC (Error-Correcting Code) support allows detection and correction of single-bit errors, which is essential for mission-critical applications such as database servers, virtualization platforms, telecommunications equipment, and industrial servers.

Key specifications include CAS latency CL5, 240-pin RDIMM form factor, and full compliance with JEDEC standards for DDR2 registered memory. The module incorporates advanced signal integrity features for reliable operation at 667 MHz, including on-die termination and robust buffering. Gold-plated contacts ensure excellent long-term connectivity and corrosion resistance in continuous operation environments.

The Samsung M393T1K66AZA-CE6Q00827 is compatible with a wide range of legacy server platforms from Dell, HPE, IBM/Lenovo, Supermicro, and other OEMs that support DDR2-667 registered ECC memory. It is engineered for 24/7 operation with reliable thermal characteristics suitable for rack-mounted server deployments.

This RDIMM is particularly suitable for capacity upgrades or replacements in existing DDR2-based servers where registered memory is required for stability and scalability. The module undergoes strict testing for compatibility and reliability under sustained server workloads. Easy installation in standard 240-pin DIMM slots allows straightforward memory expansion without major system changes.

Power consumption is typical for DDR2 technology, contributing to acceptable heat levels in older server generations. The standard 240-pin RDIMM package ensures broad compatibility with legacy server memory slots.
