Crucial CT2K4G4SFS824A 8GB (2×4GB) DDR4 2400MHz CL17 laptop RAM

SKU CH-VDWJ-5S5HV MPN CT2K4G4SFS824A

Dual-channel DDR4 kit delivers 8 GB across two 260-pin SO-DIMMs at 2400 MHz CL17 and 1.2 V for up to 30 % more bandwidth and 40 % less power

  • Capacity8GB (2 x 4GB)
  • Type260-Pin DDR4 SO-DIMM
  • SpeedDDR4 2400 (PC4 19200)
  • CAS LatencyCL17
  • Voltage1.20V
  • ECCNo

Capacity 8GB (2 x 4GB)

Struck-through versions exist but are not stocked here.

  • Dual-channel kit doubles memory bandwidth for smoother multitasking
  • 2400 MHz DDR4 speed delivers faster data rates than 2133 MT/s baseline
  • CL17 latency provides responsive performance for everyday workloads
  • 2 V operation reduces power draw by up to 40 percent extending battery life
  • 260-pin SO-DIMM form factor fits standard laptop memory slots

8 GB DDR4 SO-DIMM kit for laptop upgrades

This kit contains two 4 GB modules that run at 2400 MHz with CL17 latency at 1.20 V. It is built for notebooks that accept 260-pin DDR4 SO-DIMM memory and need a dual-channel configuration.

Simple slot insertion with standard keying

The modules are unbuffered and non-ECC so they drop into any compatible SO-DIMM socket without extra cables or drivers. Problems usually appear when a laptop BIOS limits speed to 2133 MT/s or when a single-channel board cannot use both sticks.

DDR4 2400 MT/s bandwidth ceiling

The PC4-19200 interface caps theoretical throughput at the rated speed, so workloads that need higher sustained bandwidth will not benefit from faster modules. The 1.20 V operation helps battery life but cannot overcome the standard's maximum data rate.

Questions about this item

How can I verify the kit is running at 2400 MHz with CL17 after installation?

Open Task Manager or a tool such as CPU-Z and confirm the memory frequency shows 2400 MHz and the CAS latency reads 17.

What comes in the box and do I need any extra parts?

The box contains two 4 GB DDR4 SO-DIMM modules; no additional components are required for a standard laptop upgrade.

Which version should I choose if my laptop supports DDR4 2400 and I want dual-channel performance?

This dual-channel kit provides two matched 4 GB sticks at 2400 MHz CL17, giving the full 8 GB capacity in dual-channel mode.
