NEMIX RAM 64GB DDR5 5600 ECC RDIMM 2Rx4 CL46 1.1V 288-Pin Lenovo ThinkSystem 4X77A90992 memory upgrade

Lenovo ThinkSystem DDR5 ECC RDIMM

This NEMIX RAM module delivers 64GB of DDR5 5600 registered ECC memory in a single 288-pin DIMM. It operates at 1.1V with CL46 latency and uses a 2Rx4 organisation built from major OEM DRAM. The part is validated for Lenovo ThinkSystem servers carrying the 4X77A90992 qualification.

Registered design for multi-DIMM server boards

The registered buffer reduces electrical load on the memory controller, allowing larger populations of DIMMs per channel without signal degradation. ECC circuitry corrects single-bit errors to maintain data integrity in mission-critical workloads. No heat spreader is fitted, so airflow in the server chassis provides all necessary cooling.

Suited for IT teams expanding Lenovo ThinkSystem

Buyers needing non-ECC unbuffered DIMMs for desktop platforms should look elsewhere, as the registered interface and ECC function are incompatible with consumer motherboards. Systems requiring lower latency or higher clock speeds than CL46 at 5600 MT/s will need a different module specification.
