No, it won't do any better at lower voltages... but it sure won't work any better with MORE voltage because of FSB walls... Most Q9450s, as previously said can't get more than 3.8GHz on a DECENT board.
All you're doing by giving it more volts is killing the chip.

You should never go above 1.4v Vcore and 1.4v VTT. You might have killed your chip already or severely degraded it.

Be happy if you can get 3.8GHz, as many people can't even get that.
