lenovo legion y540

well, 2666 is fastest it can run, I see that

Adding 2 reduced this to 2400 as well - link - same laptop

it could be something to do with the device.
I would suggest asking on here:

Please show screenshots from CPU-Z - memory and spd tabs.

Generally - if bios lacks options for manual ram configuration, then only automatic ram configuration is available.
It works depending on available spd profiles.
Your ram probably has profile for 2400mhz mode, but lacks spd profile for 2666mhz mode or requires use of XMP for it.

Well - your ram has spd profile for 2600mhz mode. So it should be able to use that.

BTW - what model cpu is in your laptop?

Did you do any undervolting?
You said, BIOS lacks any advanced ram configuration options.

Yes, but I just thought it might be something with using 2 sticks in that model. It was an example showing its what happens, its unclear if their reasoning was correct.

Test each of the new sticks one at a time to see what speed it shows.

It might be switching into lower ram frequency because of that.
