8GB Dual-Channel DDR4 Laptop Kit

This A-Tech kit provides 8 GB of DDR4 memory in two 4 GB modules for laptops, notebooks and all-in-one PCs. The 260-pin SO-DIMM form factor fits standard DDR4 SODIMM slots. Rated at 2400 MHz with CL17 latency and 1.20 V operation, it is designed to boost multitasking and system responsiveness.

Suits DDR4 SODIMM upgrades.

Builders upgrading a DDR4 laptop or all-in-one with an available SODIMM slot will find this dual-channel kit straightforward to install. It is not suitable for systems that require ECC, registered modules, a different pin count, or a memory generation other than DDR4.

2400 MHz DDR4 speed with CL17 timing

The modules run at DDR4 2400 (PC4-19200) with a CAS latency of 17 at the standard 1.20 V. This speed and timing combination determines whether the kit matches the memory controller specifications of the target laptop.

Questions about this item

Should I pick the 8GB dual-channel kit or look for a single 8GB module?

The kit contains two 4GB modules that run together in dual-channel mode, giving higher memory bandwidth than a single 8GB stick of the same speed.

What does DDR4 2400MHz CL17 mean for everyday laptop use?

The modules transfer data at 2400 MT/s with a CAS latency of 17 cycles, delivering responsive application loading and smooth multitasking for typical workloads.

Will the 260-pin SO-DIMM interface limit the speed in my laptop?

The 260-pin DDR4 SO-DIMM form factor supports the full 2400MHz data rate; actual speed is capped by the laptop's memory controller, not the module connector.
