My Motherboard is Asus Maximus Viii Hero & Processor Core i5 6600K and Sky Lake Processor Memory Sport is 2133Mhz compatible, i am Confused to buy the DDR 4 Ram 2133 or Above Plz Explain The Ddr 4 Bus Speed Memory Guide.

Basically the JEDEC standard for DDR4 is 2133MHz.
This is what every DDR4-compatible component (CPU/Board) has to be able to work with at least.
With XMP-technology the speed can be increased if the board supports it. Your board supports up to 3800MHz I think.

In terms of speed the clock isn't the only thing to consider but also the latency
Higher clocks come with higher latency
I once read a comparison that I kinda liked: RAM is like getting information from a book shelf. The clock speed determines how many books you can carry at once, the latency how long it takes you to carry them to your desk at the library. The more books you carry the slower you'll walk.

Generally DDR4-3000/3200 with CAS15/16 is the sweet spot these days for a setup like yours.
But gaming benchmarks show little to no improvement for a few exceptions between 3200MHz & 2400MHz.
If you do a lot of work with zipping and unzipping archives, editing and such this is a different story.
