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?

Card will be Aorus 1080 Ti. But have Kingston Hyperx 2x8GB 2133mhz only . So its not worth to sell and buy 2666mhz?

Not have cash for 3000mhz. !

I take loan cash from bank to my new platform

+ cash from work on this month. Spended all money for all. Only rams go to 2666mhz not have cash

Ok but why on intel spec they said 2666mhz?

4 x DIMM, Max. 64GB, DDR4 4000(O.C.)/3866(O.C.)/3733(O.C.)/3600(O.C.)/3466(O.C.)/3400(O.C.)/3333(O.C.)/3300(O.C.)/3200(O.C.)/3000(O.C.)/2800(O.C.)/2666/2400/2133 MHz Non-ECC, Un-buffered Memory *

From where you take it ? This is for 8700k?

sewerino26 · 14 Dec 2017 at 21:36

Yeah i know but what with cpu memory requirement

sewerino26 · 14 Dec 2017 at 21:47

Hmm i found with good prize.

But this is 1x stick 16GB DDR4 2666mhz. 2x8GB 2666mhz of the same is much more expensive. So even that 1x16GB 2666mhz will be faster than my 2x8GB 2133mhz?

But here differences are large,look:

OK !

thank you.

Intel said: Memory speed 2666mhz. What this mean? Its minimum to run 8700K without performance struggle or this is just the maxed speed of ram ? ( above is OC )

Ah sorry. You said about that stulid page earlier

Sorry

By the way, in Witcher 3 20 fps difference?!
