What this module adds

This Crucial CT8G4SFD824A module supplies 8GB of DDR4 laptop memory running at 2400 MT/s with CL17 latency. It is built for notebooks that accept 260-pin SO-DIMMs and operate at 1.20V. The dual-ranked x8 design suits everyday workloads and multitasking on compatible platforms.

Check your laptop first

Verify that your notebook uses DDR4 SO-DIMM slots and supports 2400 MT/s operation at 1.20V. The board must accept unbuffered, non-ECC modules in the standard 260-pin layout. Some systems limit speed to 2133 MT/s or require single-ranked sticks, so consult the manual or vendor documentation before ordering.

Build and daily handling

The stick has no heat spreader, keeping the profile low for tight chassis spaces. Gold-edge contacts on the 260-pin connector resist oxidation during repeated upgrades. As an unbuffered DR x8 module, it installs like standard laptop RAM and draws minimal power to help preserve battery life.

Questions about this item

What does the 8 GB CT8G4SFD824A box contain and is anything else required?

The package includes one 8 GB DDR4 2400 MT/s CL17 260-pin SODIMM module. No extra parts or cables are needed for installation in a compatible laptop slot.

How do I decide between the available speed or capacity versions of this module?

This specific part is an 8 GB dual-rank x8 unit rated at 2400 MT/s (PC4-19200) with CL17 latency. Choose it when your laptop supports DDR4 SO-DIMMs at that speed and you want a single 8 GB stick.

What does the 2400 MT/s rating mean once the module is installed in a laptop?

The memory can transfer data at up to 2400 million transfers per second at 1.20 V, delivering up to 30-percent more bandwidth and up to 40-percent lower power consumption while the dual-rank x8 organisation improves sequential throughput.
