Lenovo ThinkPad DDR4 SODIMM Kit

This 16GB kit contains two 8GB DDR4 SODIMM modules rated at 2400 MHz with CL17 timings. It is built for Lenovo ThinkPad E485, T580 and 13 (2nd Gen) laptops that accept 260-pin unbuffered non-ECC memory.

16GB dual-channel capacity and limits

Two ranks per module give 16GB total across the two slots these models provide. Everyday multitasking and office workloads run comfortably; heavier virtualisation or large media projects will hit the 32GB ceiling the platform enforces.

Matched pair simplifies installation

The sticks are tested together so the firmware trains both channels at once without manual timing adjustments. No heat spreaders are included, keeping the low-profile height required by thin ThinkPad chassis.

Questions about this item

Will these 260-pin DDR4 2400 CL17 modules work with the existing memory in my ThinkPad E485?

The kit is validated for the ThinkPad E485, T580 and 13 (2nd Gen) and runs at 1.2 V unbuffered non-ECC; mixing with the factory SODIMMs is supported by the platform.

How can I verify the 16 GB kit is running at the rated 2400 MHz CL17 after installation?

Open Task Manager or a tool such as CPU-Z and confirm the memory tab shows 2400 MT/s and 17-17-17 timings for both 8 GB sticks.

What exactly ships in the C109 package and is anything else required to complete the upgrade?

The box contains two 8 GB DDR4 260-pin SO-DIMM modules; no additional parts or tools are needed for the supported ThinkPad models.
