Computer Memory Solutions CM2048642400SO 16GB DDR4 19200 2400MHz Non-ECC SODIMM Lenovo IdeaPad S340-15IWL

Compatible Lenovo IdeaPad S340 upgrade

This 16 GB DDR4 SO-DIMM is built for Lenovo IdeaPad S340 models including the 15IWL, 15API and 14IWL. It installs in the single 260-pin slot to raise total memory to the platform maximum. The module is unbuffered, non-ECC and runs at the standard 1.2 V. Buyers whose laptops already contain soldered memory beyond the single slot cannot use this stick.

Low voltage keeps thermals simple

Operating at 1.2 V with no heat spreader, the module draws minimal power and adds negligible heat inside the slim chassis. Passive cooling from the laptop's existing airflow is sufficient for normal workloads. No fan noise or extra thermal management is introduced by the upgrade. The CL17 timing at 2400 MHz maintains efficient data transfer without raising voltage.

Steady throughput under sustained loads

The 2Rx8 organisation and CL17 17-17-17 timings deliver consistent bandwidth during long compile, render or multitasking sessions. Because the stick is validated for the specific IdeaPad S340 platforms, the memory controller maintains stable frequencies without throttling. Error-free operation is preserved across extended use. Systems limited to one slot cannot expand beyond this single 16 GB module.
