you have to add voltage to these here
vcore
qpi vtt
iohcore (i think that was the uncore)
and your system memory if need be
i've had mine run 3dmark @ 3.96ghz
up ur base clock (bclk) to 165 change ur vcore to 1.33v, qpi multi to 34x, qpi voltage to 1.35v maybe even 1.4 ifthat don't work.. uncore set to auto (max uncore will be 4000mhz.. so keep it less than that)
