Question about my build

First here my buld :

So ive noticed that my mobo doesnt support my ddr3 2133 ram and it only supports up to ddr3 1866 ram but theres no incompatibility error on pcpartpicker

so i was wondering if it maters and if it does can i get a mobo that supports it and everything else in my build

but is around the same price i have a budget of £550

Any help is appreciated

im not sure buy I bet you can look around for something about underclocking your ram for lower latencies and higher speed for it to be compatable. I'm probably wrong though :)

ok thanks

Plzz anyone i need help
