16GB DDR4 SO-DIMM for Lenovo IdeaPad S340

This 16GB DDR4 2400MHz SO-DIMM module is built specifically for Lenovo IdeaPad S340 15 AMD Series laptops including the S340-14API and S340-14IML models. The 260-pin unbuffered design matches the factory slot specification. It provides a straightforward capacity upgrade for compatible systems.

Low-voltage operation and no heat spreader

Running at 1.2V with CL17 timing, the module draws minimal power and generates little heat during typical office and web workloads. The absence of a heat spreader keeps the profile thin for tight SODIMM slots. Fan noise remains unchanged because the memory adds negligible thermal load.

Steady throughput under sustained workloads

The 2Rx8 organisation and major-brand chipset maintain stable data rates during extended multitasking or large-file editing sessions. Non-ECC unbuffered architecture means error correction is handled by the platform if supported. Performance stays consistent without thermal throttling in the supported chassis.

Questions about this item

How do I install this 260-Pin DDR4 SODIMM in my IdeaPad S340 15 AMD, and what step is often missed?

Power off and unplug the laptop, remove the base screws, open the case, insert the module at an angle into the slot until the clips click, then reassemble; the step often missed is pressing firmly until both side clips lock automatically.

What maintenance or replacement will this 16GB CL17 1.2V module need later?

No scheduled maintenance is required; if a fault appears, the limited lifetime warranty from Computer Memory Solutions covers exchange or repair against manufacturing defects.

What limit appears first under sustained use with this 2Rx8 unbuffered kit?

The system maximum of 16 GB or 20 GB across one socket is the first limit; this single 16 GB stick fills the only slot, so no further capacity can be added.
