Compatible Lenovo ThinkCentre Memory

This 8 GB DDR4 3200 CL22 UDIMM is built for Lenovo ThinkCentre M70s G3, M70t G3, M75s G2, M75t G2 and M90t G2 desktops. It delivers a straightforward capacity increase for office workloads, light content creation and everyday multitasking on those specific platforms.

Upgrading From Slower DDR4

The module replaces 2133, 2400, 2666 or 2933 MHz DDR4 memory and runs at 3200 MHz when the system supports it. The jump is worth it when the board and processor can operate at the higher data rate, otherwise the stick simply downclocks to the highest speed the platform allows.

Simple DIMM Installation

Installation follows the standard 288-pin UDIMM procedure: power off, open the case, align the notch and press until the latches click. The main issues are leaving a slot partially seated or mixing ranks that the motherboard does not support in the same channel.
