After updating to the latest BIOS BHCN31WW for my Lenovo Y540, I've noticed that my RAM Frequency has dropped from 2666mhz to 2400mhz.
As I remembered correctly, before the latest BIOS mine was running at 2666mhz.
Is this some kind of bug / glitch ? If it does then Lenovo needs to act fast.

It looks like either you or the seller has added 2 different RAMs in the system. When this happens, there is little guarantee that both will work at the regular speeds and usually they revert to the base clock supported by the laptop ie 2400MHz.
You could try checking in the BIOS if there is an XMP profile enabler and change that setting, but other than that there is not much you can do about it now.
Just another note, you'll not see any performance difference between 2400MHz and 2666 Mhz in daily activities.

The ones I got from stock is Micron 8gb which haa different RAM Timing and only JEDEC Memory no XMP.
I added Kingston HyperX 8gb but with a different RAM Timing and has support for XMP.
I recently ordered one more HyperX 8gb and decided to sell the Micron. I will update later.
Does it have impacts for Video Editing when using higher mhz on RAM ?

Not much to be honest.
Video editing is mostly affected by your CPU and in part GPU. Most video editing softwares depend on a really good CPU to maximize performance.

Updated; I've bought the same Kingston HyperX Impact 8gb 2666mhz and there, Y540 now runs at 2666mhz.
I learned my lesson. Should be upgrading the same model which is Micron in the first place.
