there were several mistakes you made.
first thinking that if someone else could achieve that type of overclock you could too without doing it in small increments and testing along the way.
two, you were completely wrong on the multi, you should have googled it and found out its 9 and not 6:http://ark.intel.com/products/29765/Intel-Core2-Quad-Processor-Q6600-(8M-Cache-2_40-GHz-1066-MHz-FSB)
three, that motherboard you have is a G43 chipset and is completely horrible to overclock with. you would have done better (but still not as high as you thought) with a P45 chipset.
four, you have no idea WTF you are doing. please stop and read some guides and understand what to do before doing it!
hope this helps. (and that you didn't fry anything!)
