NEMIX RAM 128GB (2x64GB) DDR5 5600 CL46 ECC RDIMM Lenovo SR685a V3

Lenovo SR685a V3 DDR5 Kit

This 128GB kit delivers 2x64GB DDR5 5600 ECC RDIMM modules built for the Lenovo ThinkSystem SR685a V3 rack server. Registered design and on-die ECC protect data integrity in mission-critical workloads. The dual-rank 2Rx4 organisation suits high-density memory configurations. Modules operate at 1.1V without heat spreaders.

DDR5 5600 CL46 Registered Limits

Speed locks to 5600 MT/s with CL46 latency when the platform memory controller initialises the DIMMs. Registered buffering adds one cycle of address-command delay, so real-world throughput depends on the server BIOS memory map. PC5-44800 rating defines the peak transfer ceiling; sustained bandwidth varies with channel population and rank count. Mixed-rank or mixed-voltage populations are not supported by this kit.

288-Pin RDIMM Build and Daily Use

Bare green PCB modules expose the 288-pin edge connector for direct slot insertion; no heat spreader means clearance is never an issue in dense chassis. Major OEM Samsung, Micron or Hynix DRAM chips are stress-tested under load before shipment. 1.10V operation keeps power draw predictable in fully populated servers. Buyers needing non-ECC UDIMMs or faster JEDEC speeds must choose a different product.
