4GB DDR4 2400 SODIMM for HP 14 Series

This 4GB DDR4 2400 CL17 SODIMM module is built for HP and Compaq 14 Series notebooks including the 14-cm0xxx, 14g-cx0xxx, 14q-cy0xxx and 14z-cg0xxx families. It uses a 260-pin unbuffered design running at 1.2V with a 2Rx8 organisation. The stick is sold individually as a single-piece kit.

Suitable for single-slot upgrades on supported HP

Owners of compatible HP 14 Series laptops with an empty SODIMM slot can add this module to increase memory capacity. Builders needing ECC error correction, registered buffering or a heat spreader should look elsewhere, as this is a standard non-ECC unbuffered part. Systems limited to a single memory slot cannot reach the platform maximum with only this stick.

Adds 4GB toward a 16GB platform limit

The notebook platform supports up to 16GB across two SODIMM sockets, so this module provides 4GB of headroom for everyday multitasking and office workloads. Installing a second matching stick enables dual-channel operation for higher bandwidth. A 64-bit operating system is required to address more than 4GB of total memory.

Questions about this item

My HP 14-cm0xxx has one 4 GB DDR4-2400 CL17 SODIMM installed; will this CM512642400SO module run at the same speed alongside it?

Yes — both are DDR4-2400 CL17 1.2 V unbuffered SODIMMs, so the new stick will match the existing module’s speed and timings without down-clocking.

After installing this 260-pin DDR4 SODIMM, how can I confirm the notebook recognises the full 4 GB at 2400 MT/s?

Open Task Manager → Performance → Memory or run CPU-Z; both will show 4 GB total capacity, 2400 MHz speed, and CL17 timings for the CM512642400SO module.
