Each chip is different, you can't guarantee it'll hit a certain place even its G0, it could be a crappy G0...
Run up Core Temp and show a screenshot to show the VID and temps (I just need to confirm)
Now did you just push the FSB to 3.6ghz without Voltage Increase, because thats probably your fault because thats hard to do even with Liquid Cooling System... Also disable Speedstep, for some reason I think the VID decreases when you do that..
