Can i use 8700K with 2133mhz memory DDR4?

Hi.

Hi. My rams:

https://www.morele.net/pamiec-hyperx-fury-ddr4-2x8gb-2133mhz-cl14-hx421c14fb2k2-16-869008/

Currently are on Asus Z170-P motherb and 6700K. I am buying 8700K and Asus Tuf Z370 Pro Gaming.

I must buy faster new ram or not necessary ? I dont have much money and i must safe cash for mobo.

And why on intel specification is 2666mhz memory,look:

https://ark.intel.com/products/126684/Intel-Core-i7-8700K-Processor-12M-Cache-up-to-4_70-GHz

So this mean i will be have bootleneck?

So right now me having lower MHz ram than Intel actually recommends slows down the CPU or not really?

I read many reviews that difference between 2133mhz vs 2666mhz are large and shows 20-30 fps difference.

Other reviews shows 2-3 fps marginal difference.

Like i said i must safe cash for 1080 ti . Can i use them 2133mhz for short time with 8700K ( stock ) ?

Your 2133 memory should work just fine. The number you see on ARK is the maximum validated speed; slower speeds are also fully supported.
