Compatible DDR4 SO-DIMM for Lenovo Thinkcentre

This 16 GB DDR4 SO-DIMM is built for Lenovo Thinkcentre M900z All-in-One, M910, M910q Tiny, M910x Tiny and M910z systems. It runs at 2400 MHz with CL17 timing at 1.2 V. The unbuffered, non-ECC module uses a 260-pin layout and a 2Rx8 rank configuration. It installs directly into the factory memory slots without extra setup.

Suitable for single-slot upgrades.

Buyers adding memory to a supported Thinkcentre where a single 16 GB stick matches the board limits will find this module fits the requirement. It is not suited for users who need a matched pair for dual-channel performance or who want to exceed the 32 GB total capacity ceiling of these platforms. Systems outside the listed Lenovo models should not use this part.

260-pin DDR4 SO-DIMM form factor

The module follows the 260-pin DDR4 SO-DIMM standard, which is the sole physical and electrical interface that lets it seat in the target Thinkcentre boards. A different pin count or DDR generation will not fit the slot. Confirm the motherboard accepts DDR4 SO-DIMM before purchase.

Questions about this item

What 260-pin SO-DIMM slot does this 16GB module occupy in a Lenovo Thinkcentre M900z All-in-One?

It installs in one of the two SO-DIMM sockets; the system maximum is 32GB so a second identical stick can be added later.

Which way round does the CM2048642400SO go in, and what click confirms it is seated?

Align the notch on the gold edge with the key in the slot, insert at an angle, then press down until the side clips snap into the notches on the module.

When should this DDR4 2400 stick be replaced if the system starts failing memory tests?

Swap it out if diagnostic software reports persistent errors; the module carries a limited lifetime warranty from Computer Memory Solutions.
