I also hear that ram will work at the speed of supported by motherboard as my lap has Intel I3-6006U Sky lake. Will it work fine?

Hi:

 

If DDR4-2666 memory is all you can find, or is cheaper than DDR4-2400 memory, the 2666 MHz memory chip should work just fine.

 

It will automatically bridge to 2133 MHz, because that is the fastest speed the processor your notebook has can run the memory at.

DDR4-2666 MHz memory is all CL19.

 

DDR4-2400 memory is all CL17

 

DDR4-2133 memory is all CL15

 

It will automatically bridge to CL15--(CAS Latency) speed of a 2133 MHz memory module.
