Compatible upgrade for IdeaPad 720S-14IKB

This 16 GB DDR4 SO-DIMM is built to match the Lenovo IdeaPad 720S-14IKB. It runs at 2400 MHz with CL17 timings at 1.2 V. The module is unbuffered, non-ECC and uses a 2Rx8 organisation.

Suitable for single-slot 16 GB maximum

Buyers whose IdeaPad 720S-14IKB has one memory socket and a 16 GB ceiling can install this stick and reach the limit. Systems that need ECC, registered modules or speeds above 2400 MHz cannot use this part.

260-pin DDR4 2400 MHz SO-DIMM form factor

The 260-pin DDR4 interface at 2400 MHz is the single specification that decides fitment. If the laptop requires a different pin count, voltage or generation the module will not seat or function.

Questions about this item

Does the 1.2 V DDR4 module run cool and quiet inside the IdeaPad 720S-14IKB?

DDR4 at 1.2 V draws less power than older generations, so the stick produces minimal heat and has no moving parts to create noise during all-day use.

Will the laptop accept a single 16 GB stick or do I need a matched pair?

The IdeaPad 720S-14IKB has one memory socket and supports a maximum of 16 GB, so this single module fills the only slot.

Can I keep the original 8 GB stick and add this 16 GB module for 24 GB total?

The system provides only one 260-pin SO-DIMM socket, so the original module must be removed before installing this 16 GB stick.
