4GB DDR4 2400MHz SODIMM for HP 15 Series

This 4GB DDR4 2400MHz CL17 SODIMM module is built for HP and Compaq 15 Series notebooks including the 15-da00xx, 15-db0xxx, 15g-dr00xx and 15g-dx0xxx families. It arrives as a single 260-pin stick rated at PC4-19200 with 1.2V unbuffered operation.

Laptop owners needing a direct drop-in upgrade

It suits owners of the listed HP 15 models who want to add or replace a memory stick without configuration changes. It is not for buyers whose laptops require ECC or registered modules, or for systems that only accept a different pin count or form factor.

CL17 timing at 1.2V unbuffered

The module runs at CL17 (17-17-17) timings with a 2Rx8 rank organisation on major-brand chips. That latency and voltage combination decides whether the notebook's memory controller will accept it without manual timing adjustments.

Questions about this item

Does the 1.2 V DDR4 module run cooler than higher-voltage sticks during all-day use?

At 1.2 V the SODIMM draws minimal power, keeping heat output low even when the notebook runs continuously.

Must the HP 15 Series notebook have a free 260-pin DDR4 slot to accept this upgrade?

Yes, the laptop needs an available 260-pin DDR4 SO-DIMM socket; the supported models listed have two slots and a 16 GB maximum.

Will this CL17 2400 MHz stick work alongside an existing CL15 2400 MHz module in the same HP 15?

The system will run both modules at the slower CL17 timing, so they operate together without instability.
