System-specific DDR4 SODIMM

This 16 GB DDR4 2400 MHz SODIMM is built for Lenovo ThinkBook 13s-IWL and 14s-IWL laptops plus the ThinkCentre M625q Tiny desktop. It arrives as a single 260-pin unbuffered module rated at CL17 and 1.20 V, ready for a straightforward memory upgrade.

Capacity and headroom

The stick provides 16 GB in one slot; the platforms accept up to 24 GB total depending on the model, so headroom remains for a second module if a free socket exists. Performance will settle at the slowest installed module or the processor limit, so mixing speeds reduces overall throughput.

Build integration

The non-ECC, unbuffered design needs no extra cooling or voltage adjustment and fits the factory 260-pin socket directly. A 64-bit operating system is required to address more than 4 GB, and paired modules are recommended for maximum bandwidth. Buyers whose systems already populate the only slot or require ECC registered memory cannot use this kit.

Questions about this item

Will this 16GB DDR4 2400 CL17 SODIMM run at the correct speed if I keep an existing slower module in my ThinkBook 13s-IWL?

All installed memory will operate at the speed of the slowest module or the CPU limit, so the new stick will downclock to match any slower RAM already present.

How can I verify the module is detected at 2400 MHz with CL17 timings after installing it in my ThinkCentre M625q Tiny?

Check the BIOS memory information or use a system utility such as CPU-Z; it should report 2400 MHz, CL17-17-17 timings and 1.20 V operation.

What is included with the CM2048642400SO module and is anything else required for installation in a ThinkBook 14s-IWL?

The package contains one 16 GB 260-pin DDR4 SODIMM; no extra parts or tools are needed — simply insert it into the single available socket.
