NEMIX RAM 64GB DDR4 2666MHz CL19 4Rx4 ECC RDIMM memory upgrade

Lenovo-compatible 64 GB DDR4 ECC RDIMM

This registered DDR4 module delivers 64 GB of error-correcting memory for Lenovo servers and workstations. It operates at 2666 MHz with a CL19 latency and runs on 1.2 V. The 288-pin RDIMM form factor fits compatible Lenovo platforms that require registered ECC memory.

Sustained load behaviour with 4Rx4 organisation

The 4Rx4 rank configuration spreads memory accesses across four ranks of x4 chips, helping to maintain throughput during prolonged workloads. Registered buffering reduces electrical load on the memory controller, supporting stable operation in multi-module server configurations. ECC circuitry detects and corrects single-bit errors throughout continuous operation.

Single specification that decides fit: 4Rx4

This module uses a 4Rx4 organisation and registered ECC signalling that must match the platform's memory controller requirements. Systems expecting a different rank structure, unbuffered DIMMs or non-ECC memory will not support this part. Verify the server or workstation documentation for 4Rx4 RDIMM compatibility before purchase.
