I found a motherboard that supports 2133 mhz and 2400 mhz. Then can i put there ram thats 2666 mhz
Would it even support it? Is it slower?
 
Solution
Yes, It would support it. Before tweaking the BIOS, your motherboard would run the memory at whatever it supports (2133 or 2400). If your board has XMP in the BIOS then you can clock your RAM to the 2666MHz range.

Solution
If system (BIOS) is setup on auto (default), then installed memory that has higher frequency than that (officially) supported by the motherboard will (or should) run at the maximum supported memory frequency.

In this case, 2666 MHz memory will (or should) automatically run at either 2133 MHz or 2400 MHz by the system.
