Compatible HP ENVY notebook upgrade

This 32GB kit contains two 16GB DDR4 SO-DIMM modules built for the HP ENVY Notebook 17-ae151nr and ENVY x360 Notebook 15-cn0001la. Each stick uses a 260-pin layout and runs at 2400MHz with CL17 timing. The unbuffered, non-ECC design matches the factory specification for these models.

32GB maximum across two slots

The notebooks accept a maximum of 32GB spread over two sockets, so this kit fills every available slot. Mixed modules will drop to the slowest installed speed, so a matched pair keeps bandwidth consistent. A 64-bit operating system is required to address the full capacity.

Matched pair with lifetime warranty

The two sticks are tested together to avoid timing mismatches that can cause instability. Computer Memory Solutions provides a limited lifetime warranty against manufacturing defects when purchased directly. No heat spreaders are included, keeping the low-profile form factor suitable for thin chassis.

Questions about this item

Will these 260-pin DDR4 2400MHz SODIMMs run at their rated speed if I keep one existing 16GB module in my ENVY 17-ae151nr?

The system will run all installed memory at the speed of the slowest module or the CPU limit, so mixing speeds may lower the 2400MHz rating.

How can I verify the kit is recognised at 2400MHz CL17 after installing both 16GB sticks in my ENVY x360 15-cn0001la?

Check the memory speed and timings in the BIOS or with a tool such as CPU-Z; they should show DDR4-2400 and 17-17-17.

Does the C108 package include anything besides the two 16GB SODIMM sticks, or do I need a screwdriver separately?

The box contains only the two memory modules; a small Phillips screwdriver is required to open the laptop’s memory compartment.
