About the Lenovo TruDDR5 128GB 2Rx4 PC5-51200 ECC RDIMM 6400MHz
With a CAS latency of CL46 and operating voltage of 1.1V, the Lenovo TruDDR5 128GB 2Rx4 PC5-51200 ECC RDIMM 6400MHz (part number 4X71N41584) delivers the low-latency, power-efficient performance demanded by in-memory databases and latency-sensitive enterprise workloads. This registered DIMM operates at 6400 MT/s, meeting the PC5-51200 speed rating while maintaining strict error correction through full ECC support—essential for mission-critical systems where data integrity cannot be compromised. The dual-rank, x4 die configuration (2Rx4) optimizes memory density and scalability across large server installations.
Built on the proven Lenovo TruDDR5 server memory platform, this 288-pin DIMM is engineered for Lenovo ThinkSystem servers and compatible Intel Xeon Scalable (4th Gen Sapphire Rapids and later) and AMD EPYC DDR5 platforms. The 128GB capacity per module enables consolidation of demanding workloads—from virtualization and analytics to high-performance computing—while the 0°C to 85°C operating range supports varied data center environments. Storage architects and enterprise IT procurement teams seeking maximum uptime, performance consistency, and investment protection will find this module indispensable.
