need help OC i7 950 3.06Ghz to 4.4Ghz

hi im newbie here , can anyone here help me to get i7 950 from 3.0Ghz to 4.4Ghz

I already set the setting inside bios like this , am i missing the point here on the voltage ??

In order to get a 950 to 4.4GHz you'll need to supply significantly more Vcore than 1.25V. Figure in the neighborhood of 1.4 - 1.45V for that clock. And QPI/DRAM Core voltage (VTT) of 1.6V is way too high, considering 6GB of RAM installed running at DDR3-1800 (x10 DRAM mult.), and a BCLK of only 180.

Your QPI/VTT voltage is super high. Should be more like 1.25V to 1.3V given your RAM speed.

I followed Miah's guide with my 920 for 4.2ghz (probably is more realistic for you to see 4.0-4.2 but that's still a decent boost):
