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.

商品問答

Will the 240-pin DDR3 DIMMs fit the four slots in my Lenovo ThinkCentre M91p SFF?

Yes, the 240-pin DDR3 DIMMs are the correct form factor for the four memory slots in the Lenovo ThinkCentre M91p and M91 SFF chassis.

Do I have to install the two 4 GB sticks as a matched pair for dual-channel operation?

The system requires modules to be ordered and installed in pairs to enable dual-channel mode, so both 4 GB sticks must occupy the paired slots.

When would I need to replace these 1.5 V CL11 modules?

Replace them if the system fails to POST, shows memory errors in diagnostics, or if you upgrade beyond the 16 GB maximum supported by the platform.
