16GB DDR4 SODIMM for ThinkPad L-series
This 16GB DDR4 2400MHz SODIMM module is built for Lenovo ThinkPad L470, L480, L570 and L580 laptops. It targets users upgrading a single slot to raise total memory toward the 32GB system maximum. The 260-pin form factor fits the standard SO-DIMM socket in these models.
2400MHz CL17 speed rating
The module runs at DDR4-2400 (PC4-19200) with a CAS latency of 17 and 17-17-17 timings at 1.2V. This specific speed and latency combination determines whether the memory matches the platform's supported specification. The 2Rx8 rank organisation and unbuffered, non-ECC design must align with the laptop's memory controller requirements.
Single stick enables dual-channel flexibility
The package contains one 16GB stick, allowing the owner to populate one socket now and add a matching module later for dual-channel operation. No heat spreader is included, keeping the profile low for tight chassis clearance. A limited lifetime warranty from Computer Memory Solutions covers the module against manufacturing defects.

Questions about this item
What does the 2400 MHz rating mean once this module is installed in a ThinkPad?
The module operates at DDR4 2400 with CL17 timing and 1.2 V, delivering the rated speed on the supported Lenovo ThinkPad L470, L480, L570 and L580 systems.
How does the 260-pin SODIMM interface limit what this memory can do in practice?
The 260-pin DDR4 SODIMM form factor fits only laptop slots wired for DDR4 SO-DIMM, providing a single 16 GB unbuffered non-ECC channel at 2400 MHz.
What physical space and slot layout does this stick need to fit?
It requires one free 260-pin DDR4 SO-DIMM slot; the listed ThinkPad models each have two sockets supporting up to 32 GB total.
