About the Micron DDR4 LRDIMM 64GB 4Rx4 2666 CL19 ECC Server Memory
With a CAS Latency of CL19 and operating voltage of 1.2 V, this Micron DDR4 LRDIMM delivers the low-latency, power-efficient performance critical for high-frequency trading systems and in-memory database workloads. The 64 GB capacity per module, combined with DDR4-2666 speed and 4Rx4 organization, enables enterprise data centers to maximize memory density while maintaining strict error correction standards through single-bit error correction and double-bit error detection.
Built on Micron's proven LRDIMM architecture with an integrated iMB (Isolation Memory Buffer), the MTA72ASS8G72LZ-2G6J2R is engineered for Intel Xeon Scalable Gen 1 (Skylake-SP) and Gen 2 (Cascade Lake-SP) processors on Intel C620 series (Lewisburg) chipsets. IT procurement teams and storage architects deploying mission-critical virtualization, analytics, or cloud infrastructure will appreciate the 288-pin form factor and 72-bit DRAM bus width that reduce electrical stress on server motherboards while scaling memory configurations. Rated for 0°C to 85°C operating temperatures with Micron limited-lifetime support, this module ensures reliable operation in demanding data center environments.
