Ready-to-install Lenovo ThinkCentre M81 memory kit

This 8 GB kit contains two 4 GB unbuffered DIMMs built for the Lenovo ThinkCentre M81 family. Each module runs at DDR3 1600 MHz (PC3-12800) with CL11 timing at 1.5 V. The pair enables dual-channel operation on the four-slot motherboard.

Suits owners of compatible M81 models adding

The modules work in systems listed by Lenovo part number: 0385, 1730, 5030, 5032, 5048, 5049, 7517 and 7518. Buyers who need ECC error correction, registered DIMMs, more than 32 GB total capacity or modules that exceed the 4 GB per-slot limit should look elsewhere.

Dual-channel requirement governs installation

The supplier states that modules must be ordered and installed in pairs for dual-channel mode. The kit delivers exactly two matched 4 GB sticks, satisfying that rule for a single upgrade step.

Questions about this item

How do I verify the kit runs at 1600 MHz CL11 after installing it in my ThinkCentre M81?

Enter the BIOS or use CPU-Z; the memory tab should show DDR3-1600 with 11-11-11 timings at 1.5 V, confirming the modules are operating at the rated PC3-12800 speed.

What does the CM5126412800DIMM package contain and is anything else required?

The box includes two 4 GB 240-pin DDR3 DIMMs; no extra cables, brackets or software are needed for installation in the compatible Lenovo ThinkCentre M81.

Which capacity kit should I choose for a ThinkCentre M81 with four DIMM slots?

This 8 GB kit (2 × 4 GB) fills two slots in matched pairs for dual-channel mode; the system supports up to 32 GB total, so add a second identical kit later if you need 16 GB.
