i have 2x 8gb ddr3 1866mhz rated ram and my board is z77 sabretooth, the bios would allow me to up the ram speed by a fair bit well over 2ghz, can anyone tell me if its ok to do so, the ram is g.skill f3-14900cl10-8gbxl the thing is cpu-z says on the max bandwidth section pc3-10700 (667 MHz) that would make it 1333 MHz ram wouldn't it, its in dual channel mode running xmp with my i7 3770k, when i bought the ram i bought it as 1866mhz but is it really something like 1333 or 1600 running faster than it should....so if that is the case can i go any further with it......
