16GB DDR4 SODIMM for ThinkPad E575, E585, L380

This 16GB DDR4 2400 SODIMM uses 260-pin unbuffered non-ECC memory rated at CL17 and 1.2V. It is built as a single 16GB module using a 2Rx8 configuration with major brand chipset. The kit is validated for Lenovo ThinkPad E575, ThinkPad E585 and ThinkPad L380 notebooks.

Sustained load behaviour at DDR4 2400 CL17

The module runs at the standard 1.2V DDR4 voltage with 17-17-17 timings, delivering consistent bandwidth during extended workloads. As an unbuffered non-ECC SODIMM it relies on the platform memory controller for error handling, so data integrity matches the host system capability. The 2Rx8 organisation supports dual-rank interleaving on the single stick for steady throughput.

Installation notes for 260-pin SODIMM slot

Insert the stick into an available SODIMM slot until the side clips lock; the laptop uses two slots supporting up to 32GB total. No heat spreader is fitted so clearance is minimal, but verify the retention arms engage fully on both sides. Builders who need ECC or registered memory cannot use this module, and systems requiring a different pin count or voltage will not accept it.

Questions about this item

How much power does the 1.2 V DDR4 2400 module draw when the laptop runs all day?

The module operates at the standard 1.2 V DDR4 voltage, so it adds only a small incremental load to the ThinkPad's power budget during continuous use.

What must the ThinkPad already have for this 260-pin SODIMM to work?

The laptop needs a free DDR4 SO-DIMM slot; the E575, E585 and L380 each provide two slots supporting up to 32 GB total.

Will this CL17 2Rx8 stick run correctly beside the original memory in my E575?

Yes, it matches the DDR4 2400 speed and 1.2 V voltage used by the factory modules, so the system will clock both sticks to the same timing.
