Ram Speed and CPU Compatibility

[evil_neo]

i'm planning to build a Gaming PC with:
core i7 4790k Specs Here
kingston HYPERX Fury Black 2x8 DDR3 1866 MHZ CL10 V1.5
so on the processor specs it is written under the memory specifications that
memory types: DDR3-1333/1600, DDR3L-1333/1600 @ 1.5V

does that means that the Rams won't work at all with this processor or will it work at 1600MHZ
or work at a low performance that would cause problems for the system?

It will work if the motherboard supports that speed

It will work if the motherboard supports that speed

the motherboard would be MSI z97 Gaming 5 which do supports it

just to be sure here ,the RAMs will work at 1866 MHZ , or it will work at a lower MHZ?
and if it will work at a lower MHZ , is it worth it changing the processor which would cause me to also change the Motherboard ,thus increasing the budget of the whole build?
