16GB DDR4 SO-DIMM for HP ENVY

This 16GB DDR4 2400 SO-DIMM is built for the HP ENVY Notebook 17-ae151nr and ENVY x360 Notebook 15-cn0001la. It uses a 260-pin unbuffered, non-ECC design with CL17 timing at 1.20V. The single module installs directly into an available SODIMM slot to add memory capacity.

Sustained load behaviour

Under continuous workloads the module runs at its rated DDR4 2400 speed with 17-17-17 timings. All installed memory operates at the slowest module or processor limit, so mixing speeds will lower overall throughput. The 2Rx8 organisation provides standard bandwidth for typical notebook tasks.

DDR4 SO-DIMM interface limits

The platform supports a maximum of 32GB across two sockets, so this 16GB stick leaves one slot open for a second module. A 64-bit operating system is required to address more than 4GB of total memory. Installing matched pairs is recommended to enable dual-channel operation.

Questions about this item

How much heat or fan noise does the 1.20V DDR4 2400 SO-DIMM add when the laptop runs all day?

The module runs at the standard 1.20V DDR4 voltage with no heat spreader, so it adds minimal heat and no audible noise inside the HP ENVY notebook.

What must my HP ENVY 17-ae151nr or ENVY x360 15-cn0001la already have for this 260-pin DDR4 stick to work?

Your notebook needs a free DDR4 SO-DIMM slot — the system supports up to 32GB across two sockets — and a 64-bit operating system to use the full 16GB capacity.

If I keep the original memory in the second slot, will the CL17 2400MHz timing slow down or cause errors?

All installed modules will run at the slowest speed and loosest timing present; mixing is supported, but matched pairs give the best performance.
