Compatible HP 15 Series Upgrade

This 8 GB DDR4 SO-DIMM is built for HP and Compaq 15 Series notebooks including the 15q-ds1xxx, 15q-dy0xxx, 15t-da00xx, 15t-da1xxx and 15z-db0xxx families. It uses a 260-pin unbuffered layout with non-ECC chips and a CL17 timing profile at 1.20 V. The single-module kit adds memory without requiring paired installation.

Low-Voltage Operation

Running at 1.20 V, the module draws minimal power and produces little heat inside a compact chassis. No heat spreader is fitted, so the stick relies on the notebook’s existing airflow. The DDR4 2400 rating keeps the memory controller within its standard thermal envelope during everyday workloads.

Capacity Ceiling and Pairing

The platform supports a maximum of 16 GB across two sockets, so this 8 GB stick fills one slot and leaves room for a matching module. Adding a second identical stick enables dual-channel bandwidth, which benefits integrated graphics and multitasking. Buyers who need more than 16 GB total capacity cannot use this platform.

Questions about this item

How do I install the CM1024642400SO 260-pin SO-DIMM in my HP 15 series notebook, and what step is often missed?

Power off the notebook, remove the battery if accessible, open the memory compartment, align the notch on the module with the slot key, press firmly until the side clips click, then verify the new 8GB appears in BIOS before booting the OS.

What maintenance or replacement will this DDR4 2400 module need over its service life?

No routine maintenance is required; the unbuffered non-ECC design has no battery or moving parts, and the limited lifetime warranty from Computer Memory Solutions covers manufacturing defects for as long as you own the module.

What limit appears first when this CL17 1.20V memory runs sustained workloads on a two-socket HP 15 chassis?

The platform maxes at 16GB across two sockets, so adding a second matched 8GB stick for dual-channel operation is the ceiling; beyond that the system cannot address more memory.
