A-Tech 4GB DDR4 2400 SODIMM

This 4GB DDR4 2400MHz CL17 SODIMM module is built as a compatible replacement for Crucial CT4G4SFS624A. It fits laptops, notebooks and all-in-one computers that accept 260-pin DDR4 SO-DIMM memory. The unbuffered, non-ECC design operates at standard 1.20V voltage.

Upgraders with a single-slot limit

This module suits owners who need a direct 4GB replacement or a single-slot upgrade matching the Crucial CT4G4SFS624A specification. Buyers who want more than 4GB total capacity or require ECC registered memory should look at other options.

260-pin DDR4 2400 CL17 at 1.20V

The 260-pin DDR4 interface running at 2400MHz with CL17 latency and 1.20V power draw is the decisive specification. Verify that your system supports DDR4 SO-DIMM at this speed and pin count before purchase.
