So is my i7 920, which I've had steadily overclocked at 3.8Ghz for the last couple of years, using the Asus P6T Deluxe motherboard, with 6-12 GB of Corsair TR3 1600C8D RAM and a Thermalright Ultra 120 CPU cooler.
This video
http://www.hardocp.com/news/2008/11/..._p6t_ram_ocing shows the bios settings required. Jump to 5 mins in to see the settings that need to be changed.
Basically, it's switch the 'AI Overclock Tuner' to 'Manual', disable the 'Intel Speedstep Tech', set the 'DRAM Frequency' to '1523 MHz', the 'CPU Voltage' to '1.35', and the 'DRAM Bus Voltage' to '1.66' and that's it.
Here's some info about power consumption when overclocking -

From what I can tell, roughly speaking you're looking at about a 20 Watt difference between 2.66GHz and 3.8 GHz at idle, and an 80 Watt difference under full load.
Make of it what you will.
