Crucial CT8G4SFS824A 8GB DDR4 2400 CL17 laptop RAM

Ideal upgrade for thin-and-light laptops

This 8 GB DDR4 module uses the standard 260-pin SO-DIMM form factor and runs at 1.20 V. It targets owners of ultraportable notebooks who need a single stick to fill an empty slot or replace a smaller module. The CL17 latency and 17-17-17 timings suit everyday productivity workloads. Buyers who require ECC error correction or registered buffering should look elsewhere.

Fits any DDR4 SO-DIMM slot without extra height

The stick has no heat spreader, so it clears tight chassis clearances and low-profile keyboard decks. It draws power directly from the memory controller and needs no auxiliary connectors or cooling airflow. Because it is unbuffered and single-ranked, the memory controller sees one logical rank per channel. Systems that demand dual-rank density or registered DIMMs cannot use this module.

Sustained throughput stays consistent at 2400 MT/s

The module is rated for PC4-19200 bandwidth and maintains that data rate during long compile jobs or video exports without throttling. Power draw remains at the DDR4 baseline of 1.20 V, helping preserve battery runtime under continuous load. Faster burst access improves sequential throughput when the controller issues back-to-back requests. Modules limited to 2133 MT/s will not reach this sustained ceiling.
