Is it possible to install DDR4 2400mhz memory in a laptop if there is already a DDR4 2133mhz bar?

Question

laptops

Good afternoon!
I want to add memory to my laptop. The comrade gives the bar DDR4 but 2400mhz
Can I put it next to the existing DDR4 2133mhz?
Processor: i3-6006u
Thanks in advance

Answer 1

It was possible before. It’s just that both bars will work on 2133. I don’t think that they have changed anything. In extreme cases, nothing will explode. The laptop just won't start.

Answer 2

A very informative question.
Considering that they give it to you, even if for money, take it and test it. It would be great to first read the specifications for the mother, etc., but you don’t go to the store ... in the worst case, it won’t start, at best it will work, timings and frequency, if I remember correctly, will be at the lower limit of the worst.
