H77 cannot overclock. With mismatched sticks like that it will run at the lowest common supported frequency, 1333MHz in this case.

Something lost in translation here

Now that with further reading, H77 can overclock 3rd gen CPUs (I only tested with 2nd gen). However I see no mention on memory OC, some H77 boards don't list it at all but some do. You should go into the BIOS and see if it lets you select higher memory frequencies then (not that you have to apply it, just check if the frequency option goes that far)

 

It won't crash the system with sticks rated for high frequency. CPU memory frequency limit is a software lock, not CPU's upper limit.
