Lenovo 8GB DDR3-1333 LP RDIMM 49Y1397 | Server Memory, ECC

Keep aging server platforms productive with Lenovo 49Y1397, an 8 GB DDR3-1333 low-profile RDIMM designed for compatible IBM and Lenovo systems. Its registered ECC architecture helps preserve data integrity under sustained workloads, while the 1.35 V PC3L design reduces power draw compared with standard-voltage modules. For infrastructure teams maintaining legacy x86 servers, that balance of reliability and efficiency matters. This module uses a 2Rx4 organization and a 240-pin DIMM interface, matching the requirements of supported server platforms such as the IBM System x family listed in the compatibility data. The low-profile form factor helps with clearance in populated chassis, and the CL9 timing aligns with the module’s server-class specification. It is a straightforward choice when you need to extend the service life of a qualified platform without introducing mismatched memory. Compared with generic desktop memory, this RDIMM is built for server workloads that depend on error correction, registered signaling, and validated compatibility. That makes it a better fit for virtualization hosts, file servers, and application systems where downtime costs more than the module itself.
