Lenovo 8GB DDR3-1333 RDIMM 49Y1436 | Server Memory, ECC, Registered

Maintain dependable performance on supported Lenovo server platforms with this 8 GB DDR3-1333 RDIMM. The 2Rx4 organization and registered ECC design are built for server workloads that need predictable memory behavior, clean signal handling, and error correction under continuous operation. At 1,333 MHz, this module fits legacy infrastructure that still needs to stay online without forcing a full platform refresh. It is a practical choice for extending the life of installed systems, restoring capacity in aging servers, or matching existing DIMMs in mixed-memory configurations. The RDIMM architecture helps reduce electrical load on the memory controller, which is especially important in multi-DIMM server layouts. For procurement teams and infrastructure owners, the value is straightforward: preserve compatibility, reduce replacement risk, and keep critical systems running with the exact memory class the platform expects. When a server is too important to retire and too costly to replace, the right qualified memory module is the difference between a controlled upgrade and an avoidable outage.
