OWC 8GB DDR3 ECC RDIMM

This OWC 8GB DDR3 1333 PC3-10600 CL9 2Rx4 240-pin 1.5V ECC Registered RDIMM is a system-specific memory upgrade. It is designed for Lenovo System x3400 M2, x3400 M3, x3500 M2, x3500 M3 and x3550 M2 servers and workstations. The module replaces multiple Lenovo part numbers including 0A89412, 46C0542 and 46C7449.

Suited for ECC registered servers

This module suits administrators extending the life of compatible Lenovo System x servers or building replacement infrastructure with ECC registered memory. It is not for standard desktop computers and cannot be mixed with unbuffered memory. Buyers needing unbuffered DIMMs or non-ECC memory for consumer platforms should look elsewhere.

Verify registered ECC requirement

Before ordering, confirm your system requires DDR3 1333 registered ECC RDIMMs and supports 2Rx4 8GB modules at 1.5V. Check that all installed DIMMs match in capacity, speed and type for optimal performance. Ensure the memory slots accept 240-pin registered modules and that the platform does not require unbuffered memory.
