Server memory for IBM-Lenovo systems

This 4GB DDR4 ECC RDIMM replaces IBM-Lenovo part numbers 46W0786 and 47J0250. It is built for servers and workstations that require registered, error-correcting memory. The module installs in a standard 288-pin DIMM slot and operates at the standard DDR4 voltage of 1.20V.

Registered ECC with 1Rx8 organisation

The single specification that determines fit is the registered ECC design with a 1Rx8 rank structure. Systems that require unbuffered non-ECC DIMMs or a different rank configuration will not accept this module. Compatibility must be verified against the platform's qualified vendor list before purchase.

4GB capacity for light workloads

A single 4GB module handles basic server tasks, virtualisation hosts with modest memory allocation, and legacy application servers. Workloads that demand large in-memory databases, heavy virtualisation density or high-performance computing will exceed this capacity and require higher-density DIMMs or additional populated slots.

Punti di forza
