Hi:

Chapter 1 of the service manual indicates that you can.

Maintenance and Service Guide (hp.com)

[8055nkjjjj]

 the service module says:: DDR4-2400 dual-channel support (DDR4-3200 bridge to DDR4-2666, DDR4-2666 downgrade to DDR-2400)

what does this means?

i am having 2400mhz 8gb ram in one slot pre-installed, can i add 2666mhz 8gb ram in the other empty slot?

It means that the fastest speed your notebook's processor can run the memory at is limited to 2400 MHz.

Installing DDR4-2666 MHz or DDR4-3200 MHz memory will work fine, but they will automatically bridge to 2400 MHz.

So yes, the DDR4-2666 MHz memory will work fine as long as it is CL19 and will automatically bridge to 2400 MHz.
