HP 15 Series compatible DDR4 kit

This 16 GB kit contains two 8 GB DDR4 SO-DIMM modules rated at 2400 MHz with CL17 timing. The unbuffered non-ECC sticks operate at 1.2 V and use 260-pin connectors. They are built for HP/Compaq 15 Series notebooks including the 15-ayxxx, 15-bs011la, 15-bs012la and 15-bs015dx families.

Sustained load behaviour

The modules run at standard JEDEC voltage without heat spreaders, so thermal headroom depends on the laptop chassis airflow. CL17 latency and dual-rank 2Rx8 organisation deliver stable throughput during extended workloads such as virtualisation or large spreadsheet recalculation. The major-brand chipset is validated for continuous operation at the rated 2400 MHz speed.

Pre-installation checks

Verify your notebook model matches the listed HP 15 Series part numbers before ordering. Confirm the system has two free SO-DIMM slots and supports a maximum of 16 GB total memory. Ensure the BIOS is updated to the latest version available from HP for full compatibility with this 260-pin DDR4 kit.

Questions about this item

Will the 1.2V DDR4 modules run hot or draw extra power when the notebook is under load all day?

The kit operates at the standard 1.2V for DDR4 SODIMMs, so heat and power draw stay within normal laptop limits during extended use.

My HP 15-ayxxx has two SODIMM slots — do I need any extra parts to install this 2 x 8GB kit?

No extra parts are required; the two 260-pin modules fill both slots directly for the 16GB maximum the notebook supports.

If I keep one existing 8GB stick and add one 8GB module from this kit, will the system still run at 2400MHz?

Mixing ranks or timings can force the memory controller to drop speed; using the matched 2Rx8 pair together avoids that risk.
