ThinkCentre M73/M73E Upgrade Kit

This 16 GB kit is built for Lenovo ThinkCentre M73 and M73E small-form-factor and tower desktops. It delivers two 8 GB DDR3 modules that match the platform's maximum supported capacity. Office users and IT refresh teams can restore full memory headroom without guessing compatibility.

240-Pin Unbuffered DIMMs

Each stick uses standard 240-pin DDR3 layout with no heat spreader, so it fits the tight slots inside the M73 chassis. The 1.5 V JEDEC voltage and CL11 11-11-11 timings align with the system's default BIOS settings. Installation is a simple press-in action with no extra cables or firmware steps.

DDR3 1600 Platform Ceiling

The memory runs at DDR3 1600 (PC3 12800), which is the fastest speed the M73 chipset officially supports. Faster DDR3 modules will down-clock to this rate, so buying higher-spec sticks adds no performance. Builders needing more than 16 GB total or ECC error correction must choose a different platform.

Questions about this item

What speed does the DDR3 1600 (PC3 12800) rating deliver in this kit?

The modules run at 1600 MHz with CL11 11-11-11 timings at 1.5 V.

Will the 240-pin DIMMs fit the small-form-factor ThinkCentre M73 chassis?

Yes, the kit is validated for both Small and Tower M73/M73E models with two DIMM slots.

What is the correct way to install the two 8 GB sticks, and what mistake should I avoid?

Populate both slots (the system has two sockets); the common error is leaving one slot empty and running single-channel.
