Ram question: difference between cpu and motherboard support, performance?

[Blitz Blitz]

Hi, I don't know how to explain or formulate question, but for example:

CPU: I3 - 6100: Memory Types DDR4-1866/2133, DDR3L-

MB: GA-Z170-D3H: Support for DDR4 3466(O.C.) /3400(O.C.) /3333(O.C.) /3300(O.C.) /3200(O.C.) /3000(O.C.) /2800(O.C.) /2666(O.C.) /2400(O.C.) /2133 MHz memory modules

So if I add 3000 mhz ram to my system it's will performs better? There is direct relation between CPU and MB? Or 2133 Mhz memory it will be fine too?

2133mhz will be fine

usually you can get up to 2400--2666mhz for around the same price

3000mhz will cost more and you wont really notice the difference in real life use

Faster DRAM will improve performance overall depending on what all you do, very handy for multi-tasking, and in some games. My clients are going to the 2800-3000-3200 range for best bang for the buck performance wise
