Hi there Guys,*
I'm planning to build my dream gaming PC
I bought all components except MOBO and RAM.
Formula will be released soon, and my question is will g skill rob 4133mhz 16gb 8x2 work with this mobo? I checked the VQL and I can't see this ram on compatibility list.
I can buy 3866......im really stuck when it comes to speed ? Please tell me which ram speed will suit me best
my cpu is 8700k.

Btw sorry for my English.*

4133mhz will be at the high end of the capabilities of the motherboard and CPU, get the memory kit that matches your system build, either RGB or the color of the modules
There is very little performance gains from 3200mhz 14-14-14 and 4133 at 19-19-19, lower timings can bring as much or more performance than just speed alone. There are kits of the same speed with different timings, get the kit with the lower timings if it's in your budget, 4133 19-19-19, is a little better than 4133 19-23-23
Either way if you have issues at 4133 you can manually set them to a lower speed and tighter timings
Your CPU will be the biggest factor as they vary in there capabilities more so than the motherboard

No one ever has to be sorry for the language they speak or don't

Firstly many thanks for your reply. Your point has made me think and u are right buying 4133mhz with 19 timings will not give me much performance when comparing ram with lower timings. Thank god i didnt bought them yet. I thought if i get 4133mhz ram i can change these speed to be 3600mhz for example....
Also the price difference is huge and to conclude its not really worh it...
Which RAM would u buy it >??

Many thanks for your response, help me a lot.

Memory prices are very high at the moment and running 4133 at a lower frequency is fine, I typically do this for daily stability and lower voltages.
My choices would be 3200 cl14-14-14, 3600 cl 16-16-16, the 3200 and 3600 kit typically can be run up to 4000 mhz if your CPU is capable. Samsung B-die chips are the modules of choice and typically can run at the same speeds and timings, not guaranteed but common

Yeah the prices go up 100% for some reason....Last question - what if i get 4000/4133mhz and run them as XMP and thats all. do i need to change anything else.?

Id advise kits rated no faster than ddr4-3600 on this platform. Faster speeds are conditional and can require manual tuning.

Many thanks Guys,
Thats all from my side/

Btw -
Found 3 rams:
Not sureew which one to choose : Pls help

The 3600mhz are similar to each other just different timings(and price is higher) dont get it :)
What u think

Either the 3600 C16 or 3200c14, these are 2 of the best kits available, I have the 3600 c16 4x8 kit on my X Hero without any issues, you may have to manually set VCCIO and VCCSA voltages for XMP to be 100% stable

Same frequency with lower timings means a better binned kit

Ok thanks.
I will buy 3600 mhz with lower timings then.

I have also been having this issue but with me Z370-F Board. My LED's used to be working and for some reason they don't light up anymore. I have tried all the different BIOS versions even the ones in BETA, I can't get it to light back up. Occasionally the bottom LED will change to red but then go off again so I am sure that's it's not a connection issue as it was working previously.
