Targeted 16 GB upgrade for Lenovo IdeaPad S145

This 16 GB DDR4 SODIMM is built specifically for Lenovo IdeaPad S145 models including 14‑inch and 15‑inch AMD and Intel series such as S145‑15IWL, S145‑14IWL and S145‑15IKB. It provides a single‑module capacity increase for users whose laptop has one memory slot and a 16 GB or 20 GB maximum. The module installs directly into the 260‑pin socket without further configuration.

Single stick with lifetime exchange coverage

The package contains one 16 GB stick rated at 2400 MHz with CL17 timing and 1.2 V operation. Computer Memory Solutions backs the module with a lifetime exchange or repair warranty against manufacturing defects when purchased from them, replacing the stick if a fault appears. No additional software, cables or brackets are included.

Unbuffered non‑ECC build for slim laptops

The module uses an unbuffered, non‑ECC design with major‑brand chips and no heat spreader, keeping the profile low enough for thin IdeaPad chassis. Its 260‑pin edge connector matches the factory SODIMM slot exactly, so installation is a simple press‑in action. Builders needing ECC, registered memory or a second module for dual‑channel should look elsewhere.

Questions about this item

Will the 1.2 V DDR4 SODIMM need any firmware updates or periodic re-seating over its lifetime?

No firmware updates are required; the module is a standard 260-pin DDR4 SO-DIMM that remains seated once installed in the IdeaPad S145 slot.

What is the first limit reached when the memory runs at 2400 MHz CL17 continuously?

The CAS latency of 17 cycles at 2400 MHz sets the timing floor; sustained workloads cannot push latency lower than the rated 17-17-17 timings.

How much heat and power does the 16 GB stick draw during all-day operation?

It operates at the standard DDR4 1.2 V without a heat spreader, so power draw and thermals stay within normal SO-DIMM limits for the IdeaPad S145 chassis.
