Lenovo 4GB DDR3-1333 RDIMM 49Y1424 | Server Memory, ECC, Registered

Extend the usable life of IBM server platforms with a 4 GB DDR3-1333 registered ECC memory module built for controlled, predictable expansion. The 49Y1424 RDIMM uses PC3L-10600 signaling, 1.35 V low-power operation, and registered buffering to support server workloads that depend on consistent memory behavior. This module is suited to environments where compatibility is non-negotiable. It is listed for IBM System x3650 M3 servers and aligns with the memory architecture expected in that class of hardware. ECC helps protect data integrity, while registered signal processing supports stable operation in server configurations that run continuously. For procurement teams maintaining legacy infrastructure, this part offers a straightforward way to replace failed DIMMs or add modest capacity without changing platform standards. It is a practical choice for file services, management nodes, and smaller application roles where exact-fit memory matters more than oversized capacity. When the goal is to keep a trusted server in service, this module delivers the right specification in the right form factor.
