What this memory is and who it fits

This kit provides 16 GB of DDR4 SO-DIMM memory in a matched pair of 8 GB modules. It is built for HP ZBook 15 G5 and ZBook 17 G5 mobile workstations that use 260-pin DDR4 slots. The modules run at 2666 MHz with CL19 timings at 1.2 V.

What to verify before ordering

Confirm your workstation accepts non-ECC, unbuffered DDR4 SO-DIMMs and has free 260-pin slots. The system must support 2666 MHz operation and 1.2 V modules. Check the current memory configuration to ensure the total capacity will not exceed the 64 GB maximum across four sockets.

Thermals, noise and power in daily use

These low-voltage modules draw minimal power at 1.2 V and have no heat spreaders, so they add little heat inside the chassis. Fan noise remains unchanged from the factory configuration. The kit contains no moving parts and produces no audible noise during operation.

Questions about this item

What comes in the box and do I need anything else to install it?

The package contains two 8 GB DDR4 SO-DIMM sticks. No extra parts or tools are required; they slot directly into the ZBook 15 G5 or ZBook 17 G5 memory sockets.

Should I pick this 16 GB kit or a different capacity for my ZBook 15 G5?

This 16 GB (2×8 GB) kit fills two of the four slots and leaves room to reach the 64 GB maximum later. Choose it if 16 GB meets your current workload.

What does the 2666 MHz rating mean once the modules are in my ZBook 17 G5?

The memory will run at 2666 MHz with CL19 timing at 1.2 V, delivering PC4-21300 bandwidth for the workstation’s supported DDR4 SO-DIMM slots.
