Server memory upgrade

This 8GB DDR3 module is an ECC registered RDIMM built for Lenovo System x3550 M3, x3620 M3, x3630 M3, x3650 M3 and x3850 X5 servers. It replaces multiple Lenovo part numbers including 46C0542 and 49Y1436 for straightforward capacity expansion.

DDR3 interface limits

The module runs at 1333 MT/s with CL9 latency on a 240-pin registered interface at 1.5V. ECC registered memory cannot be mixed with unbuffered modules and will not function in standard desktop platforms that lack registered DIMM support.

Registered ECC requirement

The single specification that decides fit is the registered ECC design; only systems qualified for 2Rx4 registered DIMMs can use this upgrade. Buyers whose platforms require unbuffered non-ECC memory cannot install this module.
