Solved How do I change RAM speed with Z77 Extreme4? Tags: RAM Motherboards Last response: July 1, 2013 9:05 PM in Motherboards Share TYTSoldier July 1, 2013 8:48:41 PM I heard about something called XMP, but don't know how to access it. I can't find any tabs that let you change the memory speed. My sticks are supposed to be 1600, but they were at 1333 by default.
