4 GB DDR4 2400 MHz SO-DIMM desktop RAM

This HP-branded module provides 4 GB of DDR4 memory at 2400 MHz in a SO-DIMM form factor. It is designed for seamless system-level integration with business notebook PCs. The low-power, high-speed memory improves start-up times and allows more programs to run simultaneously. Users can easily toggle between applications with better responsiveness.

Who this suits and who should look elsewhere

This module suits owners of compatible business notebooks that accept DDR4 SO-DIMMs and need a 4 GB upgrade for daily workloads. Buyers who want more storage capacity per module or require a different form factor such as standard DIMM should look at other options. Systems that do not support DDR4 SO-DIMM memory cannot use this part.

The specification that decides fit

The 2400 MHz DDR4 SO-DIMM interface is the single specification that determines compatibility. Your notebook must accept DDR4 SO-DIMM modules at this speed for the upgrade to work. Verify the memory slot type and supported speed before purchase.
