you can not answer my question but there is no problem.thanks. I did what I wanted to do.I increased the ram cappacity to 12gb from 8gb.one more question I believe you can answer me. I did well to put 2666mhz or I had to install 2400mhz? but the preinstalled ram is 2666mhz.thanks.

Here are the specs:
The modules are DDR4-2666 SO-DIMM but the motherboard can only run memory at 2400. The specs clearly say it is 2400 mhz memory. You were right to match the speed of the originally installed RAM.
