8 GB DDR4 SODIMM for ThinkPad X260

This single 8 GB DDR4 SODIMM module is built for the Lenovo ThinkPad X260. It installs in the laptop’s sole 260-pin slot and delivers 2133 MHz speed with CL15 latency at the standard 1.2 V operating voltage.

Capacity and headroom

The stick provides 8 GB of unbuffered non-ECC memory in a dual-rank 2Rx8 layout. The X260 supports a maximum of 16 GB across its single socket, so this module leaves one upgrade step remaining if the system currently runs a smaller stick.

Deciding specification

The critical detail is the 260-pin DDR4 SODIMM form factor combined with 2133 MHz DDR4-17000 signalling; only modules matching that exact pin count, voltage and speed will fit and run correctly in the X260.

Questions about this item

Will this 260-pin DDR4 2133MHz SODIMM work with the original 4GB stick already in my ThinkPad X260?

Yes, the module is DDR4 2133MHz CL15 1.2V unbuffered non-ECC 2Rx8, matching the X260 memory specification. Mixing ranks is supported by the platform, though identical modules give best stability.

How can I verify the CL15 15-15-15 timings are active after installing the CM10246417000SO?

Enter BIOS or use a tool such as CPU-Z on Windows; the SPD tab will show DDR4-2133, CAS 15, 15-15-15 and 1.2V if the module is running as specified.

Does the package include only the 8GB SODIMM or are tools and a heat spreader also supplied?

The package content lists one memory RAM stick only. No screwdriver, heat spreader or additional accessories are included.
