  • 260-pin SODIMM form factor fits HP 15 series notebooks

Targeted Notebook Upgrade

This 4 GB DDR4 SODIMM is built for HP 15 Series notebooks including the 15-bs753tx, 15q-ds00xx, 15q-dy0xxx, 15t-da00xx and 15z-db0xxx models. It adds a single 260-pin module to a compatible slot. Buyers needing more than 16 GB total capacity or a second module for dual-channel bandwidth should look elsewhere.

Steady Workload Behaviour

The module runs at 2400 MHz with CL17 timings and 1.2 V unbuffered voltage. Under sustained load it maintains the rated frequency without throttle because no heat spreader is fitted and the major-brand chips are specified for continuous operation. Non-ECC design means single-bit errors are not corrected automatically.

Straightforward Installation

Insert the stick into an empty 260-pin SO-DIMM slot until the side clips lock; no tools or firmware changes are required. The kit contains one module only, so systems with two populated sockets need a matching stick to reach the 16 GB maximum. Compatibility is guaranteed by the manufacturer for the listed part numbers.

Questions about this item

Does the 1.2 V DDR4 2400 MHz module run hot or draw extra power during all-day use?

The stick operates at the standard 1.2 V for DDR4 2400 MHz, so heat and power draw stay at normal JEDEC levels for this speed.

My HP 15 notebook has two SODIMM slots — do I need any other parts to install this 260-pin stick?

No extra parts are required; the module fits directly into a free 260-pin DDR4 SO-DIMM slot on the supported HP 15 series models.

If I keep the original 4 GB stick and add this CL17 2Rx8 module, will both run at 2400 MHz?

The system will clock both modules to the lowest common speed; with a matching 2400 MHz stick they run at 2400 MHz, otherwise at the slower module's rate.
