Technical Architecture & Memory Specifications

The Virtium VL31A4G63A-C3MF is an industrial-grade 32GB DDR4-3200 ECC Unbuffered DIMM (ECC UDIMM). It features a 2Rx8 (Dual Rank x8) organization utilizing high-reliability Micron DRAM components. Operating at a standard 1.2V with a CAS Latency of CL22 (22-22-22 standard timings), this module integrates an SPD EEPROM with a thermal sensor for advanced temperature monitoring. The standard height profile (1.23 inch) ensures broad physical compatibility across standard chassis designs.

Platform Compatibility & Server/Desktop Application

Designed for mission-critical embedded computing, telecom, workstation, and server platforms requiring error correction. This ECC UDIMM is compatible with motherboards and processors that explicitly support Unbuffered ECC memory, such as select Intel Xeon, AMD Ryzen PRO, and AMD EPYC platforms. Note: This is Unbuffered memory (UDIMM) and is strictly not compatible with systems requiring Registered (RDIMM) or Load-Reduced (LRDIMM) memory.
