I'm perfectly aware of that, neither is mine.
The non-K chips can be set to six speed bins (600MHz) above their stock speed by adjusting a simple setting present in 'Z' chipset motherboards. The K chips can be set much higher than this, but still on average only go to somewhere between 4.6-5.0GHz.
Stock, an i7 3770 runs at 100MHz x 37 = 3.7GHz. As long as you have a Z68, Z77 or Z78 chipset motherboard, you will be able to turn up your multiplier as high as 43, resulting in a clockspeed of 4.3GHz. If you are on a P or H series board you will not have this option.
