Targeted Lenovo IdeaPad upgrade

This 16 GB DDR4 SODIMM is built for Lenovo IdeaPad C340 14-inch and 15-inch models as well as the S145-15AST. It arrives as a single unbuffered module that installs directly into the laptop’s memory slot.

DDR4 2400 MHz platform ceiling

The module runs at 2400 MHz with CL17 timing and 1.2 V operation. System memory speed will match the slowest installed module or the processor’s supported rate, so overall throughput is limited by the platform rather than the stick itself.

Single-slot 16 GB maximum

The compatible laptops provide only one memory socket, making this 16 GB module the largest single-stick upgrade available. Buyers who want more than 16 GB of total memory cannot add a second module on these systems.

Questions about this item

Should I pick the 16 GB stick or aim for 20 GB or 24 GB total in my IdeaPad C340?

The module is a single 16 GB stick; the laptop has one socket, so 16 GB is the maximum this upgrade can provide.

What does the 2400 MHz rating deliver once the stick is installed?

The memory will run at 2400 MHz with CL17 timings at 1.2 V, giving the speed the platform supports for DDR4 SO-DIMMs.

Does the 260-pin DDR4 SO-DIMM interface limit anything in practice?

It fits the 260-pin DDR4 SO-DIMM slot in the compatible IdeaPad models and operates as unbuffered, non-ECC memory.
