    :D should be easy, even at 'auto' ...

    go to enhanced cpu features and set all 4 turbo's to 45x ... basically that is all I had to do for my first basic OC on my Z68X-UD3H-B3, with the same cpu and memory... those are the corsair whites, right?

    if so select xmp profile1 and answer NO to 'enhance cpu performance', that will put them at 1600/c9/1.35v, without doing anything else.

    disable cpu spread spectrum,disable pll overvoltage,set cpu power limit to 120% (not sure with gigabyte boards) set llc to high and voltage offset or cpu dvid to +0.050v,might be ok with qpi/vtt on auto of 1.05v and set dram voltage to 1.35v,set ram speed to 1600mhz and timings to spec

    put cpu multi to 45,dont touch bclk,leave it at 100,

    try that and see if you have anyluck,ideally you want/need cpu voltage around 1.36v mark for 4.5ghz

    Oh, I'm sorry my setting did not work for you, I did this with 2 cpu's and both did work that way, but there is no guarantees in overclocking ofcourse.
    Usually the best way is to do overclocking step by step, so you don't just go to 45x, but slowly move up from the default, going multiplier by multiplier. That way you get a feel for the cpu, you will know how much vcore the particular cpu needs to get to a certain speed.

    There are some tutorials for it, a nice one I found is this: Sandy Bridge Overclocking Guide , that's how I did my first 45x and how I cpu-z validated at 51x.
