The memory controller is set to 1333 MHz by default, but can run at 1600 MHz. When Intel lists 1066/1333 MHz, it just means that those are the "officially supported" speeds. It will run just fine at 1600 MHz. Just select XMP mode in the BIOS and set it to 1600 MHz. If you don;t set it yourself it will still work, it just might run at a slower speed (1333 MHz).
My RAM is running at 1600 MHz with an i5-2500k, so it definitely works.
