Lenovo IdeaPad S340 S145 upgrade
This 16 GB DDR4 SO-DIMM is built specifically for Lenovo IdeaPad S340 and S145 laptops. It targets owners who need the maximum single-module capacity these platforms accept. Buyers with other notebook models or desktop systems cannot use this module.
260-pin unbuffered non-ECC build
The stick uses a standard 260-pin SO-DIMM edge connector and operates at 1.2 V without ECC or buffering. Major-brand chips are mounted directly on the PCB with no heat spreader, keeping the profile low enough for thin chassis. Installation is a simple slot-in action; no tools or configuration are required.
DDR4-2400 CL17 single-channel limit
Running at 2400 MT/s with 17-17-17 timings, the module delivers PC4-19200 bandwidth on a single 64-bit channel. The platform supports only one memory socket, so total capacity stops at 16 GB or 20 GB depending on the exact model. Users needing more memory or dual-channel throughput must choose a different laptop.

Questions about this item
Does this DDR4-2400 SODIMM run at the full 2400 MHz on a Lenovo IdeaPad S340-14?
It is rated DDR4 2400 (PC4-19200). The laptop’s memory controller will set the final speed.
Will the 260-pin module fit the S145-15API AMD model?
Yes. The 260-pin SO-DIMM matches the slot used by the listed S145-15API and S340 models.
What is the correct way to seat the stick, and what step do people miss?
Align the notch, insert at an angle, then press down firmly until both side clips click. People often stop before the clips engage.
