Hi RazerWaleed and Welcome to ROG 🙂
You have purchased OC DIMMs and not guaranteed to work. Your MB may support them however, will the CPU.?
Your CPU supports: Memory Type DDR4-1866/2133 and any frequency above 2133MHz is considered an OC. Your Bios will default to 2133MHz.
What this means is, it will depend on the strength of your processors IMC (Integrated Memory Controller) if it will play fair. You will have to change your Primary Timings and voltage manually in Bios to correspond with what is indicated in CPUz for your SPD information. You may have an XMP profile however there is no guarantee this will work.
If you can't get them to work at their rated frequency then return them and get 2133MHz DIMMs.

Hello,
I have installed Corsair DDR4 RAMs 8x2 on my MB, and i can see on default setting on the BIOS showing 2133Mhz where its 3200Mhz?
I tried to change it from the Extreme tweak to 3200 manually; but from the BIOS if i go to EZ-MODE (F7) i see the DRAM section shwing the two RAMS slot but with 2133MHz and not 3200Mhz?
Also from inside OS when i use CPU-Z and go to SPD Tab, i see in SLot#1 and Slot#3 following value for MAX Bandwidth ( DDR4-2133 (1066 Mhz).
Part Number:- CMK16GX4M2B3200C16.
Thanks.

Hi RazerWaleed
In cpu-z click on the memory tab and double what the Dram frequency is showing, this is the actual speed your ram is running at. So for 3200MHz the Dram frequency should be showing 1600MHz.
1) 2133MHz is standard for z170.
2) Ram isn't a big factor in performance but you want to run it at its rated specs, it should make your pc a little more snappy and boost benchmark scores a little.
3) Set your ram to its rated specs and get it stable then proceed to overclock your cpu.
4) In some cases you will need a little more cpu core voltage with high speed ram, the voltages to play with to get high speed ram stable are:
CPU VCCIO voltage
CPU System Agent voltage
Dram voltage if needed.
I'd let the cpu core voltage at 1.l8v and play with the voltages above.
