[SOLVED] Motherboard compatibility

[SamJofficial]

So I'm about to buy a motherboard (gigabyte H310M S2P) which specified with 2666 mhz dual channel RAM support, 9th/8th gen LGA 1151 cpu support, and I'm gonna buy a core i3-9100F cpu which supports maximum 2400 mhz of the RAM speed.
The question is, first of all does a 2400 mhz ram would match up with the motherboard, I mean the speed "2666 mhz" of ram support for motherboard, is that a maximum number or a specific number which means I'm only allowed to buy 2666 mhz ram and not lower or higher?
Second question: If I buy a 2666 mhz ram, would my cpu support only 2400 mhz of that or is it just dont work together??
Third question: Is even my 2400 mhz of ram support cpu, would match up with my 2666 mhz of ram support motherboard? I mean first of all I just wanna know if my motherboard and cpu would match together, then if they do, what kind of ram should I get?

From your MB specs>>>
Support for DDR4 2666/2400/2133 MHz memory modules

": If I buy a 2666 mhz ram, would my cpu support only 2400 mhz of that or is it just dont work together?? "
I think it would probably run at 2400 MHz.

"Is even my 2400 mhz of ram support cpu, would match up with my 2666 mhz of ram support motherboard? I mean first of all I just wanna know if my motherboard and cpu would match together, then if they do, what kind of ram should I get? "

The i3-9100F is on Gigabyte's CPU list for that MB.

Make sure you are using BIOS F12 or later.

I would just get 2400 speed RAM with that CPU and make sure you are using BIOS F12 or later and you should be all set.

With your CPU and board it will run at 2666.
Like stated above make sure the board has the BIOS update to support that CPU.

"Support for Extreme Memory Profile (XMP) memory modules "
this means the board can use faster RAM up to 2666.
