Hi:

If you look at chapter 1 of the service manual, the notebooks that use DDR3L-1600 memory only run the memory in single channel mode--even with two memory chips installed.

So, the 800 MHz reported speed is correct.

HP Notebook PC (AMD) * Models: 15-ba100 – 15-ba199 * Models: 15-ba000 – 15-ba099 * Models: 15-bf100 ...

Two non-customer-accessible/upgradable memory module slots
DDR3L-1600 single channel support

Even if the notebook ran the memory in dual channel mode, the speed would still only show 800 MHz

When the memory is running in dual channel mode you multiply the 800 x 2 and that is how you get the 1600 MHz speed.

You can run the free utility that I zipped up and attached below and it will show you how the memory is running (in single or dual channel mode).
