XMP is Intels eXtreme Memory Profile. Basically it's a factory set of OC values. Most ddr3 default speed is 1333 or 1600. 1866 would be considered OC, so the factory designates XMP profile #1 as 1866. When you first install the ram, it'll run at default speed of 1600MHz, you must physically enter bios and set the XMP to the profile needed. So 3000 might be #1, 2666 might be #2, 2400 #3 etc but it all starts at 1600 default. Because that's what Intel designated as default memory controller speed in the cpu.
The ability above is standard Plug-n-play ram, it'll boot in anything at default speeds, up to you and the ram to change things in bios. Kingston HyperX has changed that, and removed the plug-n-play entirely, so no XMP value. If the ram is 3000MHz, it's default speed is 3000MHz, or 1600 or 1866, whatever the ram is rated at. Which is good in the sense that there's nothing to mess with, but bad in the sense that the ram is basically proprietary, it only matches up with the same value. If you stuck a stick of 2400 in with a stick of 3000, you'll have issues.
