Targeted upgrade for Lenovo Thinkcentre M78

This 8 GB DDR3 DIMM is built specifically for the Lenovo Thinkcentre M78 Small and Tower chassis. It delivers a single-module capacity increase for office desktops that need more headroom for everyday multitasking. The module matches the system's native 1600 MHz speed and 1.5 V requirement.

Fits straight into the four DDR3 slots

The 240-pin unbuffered stick works with the four memory sockets found in the M78 platforms listed in the specifications. Adding this module leaves three slots open for future expansion up to the 32 GB system maximum. Non-ECC operation is required by the platform.

Single stick with lifetime backing

The package contains one 8 GB memory module and no additional cables, brackets or software. Computer Memory Solutions provides a limited lifetime warranty when purchased directly from them. The 30-day money-back window offers a return option if the upgrade does not meet expectations.
