4GB DDR4 2400MHz Laptop Module

This A-Tech 4GB DDR4 2400MHz CL17 SO-DIMM is a new laptop memory upgrade built with major brand chips. It runs at the standard 1.20V voltage and uses the 260-pin form factor. The module is unbuffered and non-ECC, designed for straightforward installation in compatible notebooks.

Suits Single-Slot Upgrades, Not High-Capacity Builds

The 4GB capacity works well for replacing a failed stick or adding memory to a single free slot in a basic system. Buyers who want more storage for demanding multitasking or content creation should look at higher-density modules. Systems requiring registered or ECC memory cannot use this unbuffered stick.

CL17 Latency At DDR4 2400 Speed

The CAS latency of CL17 at 2400MHz (PC4-19200) is the key timing figure that determines compatibility with the memory controller. Match this specification exactly to the slot requirements listed in your laptop manual before ordering.

Questions about this item

How much heat and power does the 1.20V DDR4 module draw when the laptop runs all day?

The module operates at the standard DDR4 voltage of 1.20V, keeping power draw and heat output low during continuous use.

What must my laptop already have for this 260-pin SO-DIMM to work?

Your laptop needs a free DDR4 SO-DIMM slot that accepts 260-pin modules and supports 2400MHz operation.

Will this CL17 2400MHz stick run correctly alongside the original memory in my older notebook?

It will run at the lowest common speed and latency; if the original memory is slower, this module downclocks to match.
