Compatible 16 GB DDR4 SODIMM for ThinkPad E470.

This 16 GB DDR4-2400 module is built for Lenovo ThinkPad E470, E475 and E480 laptops. It uses a 260-pin SO-DIMM form factor, runs at 1.2 V and carries CL17 latency. The kit contains a single unbuffered, non-ECC stick.

Single-stick 16 GB kit leaves one slot free

The package supplies one 16 GB module, so a second slot remains open for a future upgrade. The system maximum is 32 GB across two sockets, allowing you to add another identical stick later if required.

Verify your model and free slot before ordering

Confirm the laptop is a ThinkPad E470, E475 or E480 and that at least one SO-DIMM slot is vacant. The module is 2Rx8 rank and non-ECC; systems needing ECC or a different rank configuration will not be compatible.

Questions about this item

Will the 2Rx8 rank configuration ever require a firmware update or module replacement on my ThinkPad E470?

The module uses a fixed 2Rx8 organisation with major-brand chips and carries a lifetime exchange warranty from Computer Memory Solutions; no firmware updates apply to the memory itself.

What is the first limit reached when the SODIMM runs continuously at 2400 MHz CL17?

Sustained operation is bounded by the JEDEC 1.2 V DDR4 specification and the laptop’s thermal design; the memory has no heat spreader, so the platform’s cooling becomes the limiting factor.

How much extra heat and power does the 16 GB stick add when the ThinkPad E480 runs all day?

At 1.2 V the module draws only the standard DDR4 power for its capacity and speed, and without a spreader it relies on the system’s existing airflow, adding minimal thermal load.
