Computer Memory Solutions 8GB (2x4GB) DDR3 1600MHz CL11 1.5V Lenovo M91P/SFF

Lenovo ThinkCentre M91P/SFF DDR3 Kit

This 8 GB kit contains two 4 GB DDR3 modules built for Lenovo ThinkCentre M91P and M91 SFF desktops. Each stick is a 240‑pin unbuffered DIMM running at 1600 MHz with CL11 timing at 1.5 V. The non‑ECC design matches the original specification for these small‑form‑factor systems.

Upgrading from lower capacity or speed

The kit replaces factory‑installed 2 GB or 4 GB modules and moves the memory bus from 10600 to 12800 transfer rate. The jump is worth it when the workload needs more than 4 GB total or when dual‑channel bandwidth improves integrated graphics responsiveness. Maximum supported memory per socket is 4 GB.

Two‑stick kit for dual‑channel operation

Modules must be installed in matched pairs to enable dual‑channel mode on the four available slots. The 1Rx8 rank layout fits the platform without requiring a heat spreader. A 64‑bit operating system is required to address the full 8 GB capacity.
