My ram sticker shows 2133mhz timing 10 11 10 31, 1.5v and my cpu is i7 4790k which can only handle 1600mhz ram. my question is that should input 1600mhz timing 9 9 9 24 1.5v or 1600mhz timing 10 11 10 31, 1.5v in the bios since I cant use xmp profile? Or should I set xmp profile and select 1600mhz as the speed instead of 2133mhz?
