Hey labbu first advice I can give you would be to see how good your core is and then work from there, find your cores lowest voltage settings on stock speeds and then that should give you a rough idea of its potential (mine was running stock at 0.96v), god I love the q9550's :p. Also I hope you have some half decent cooling too like an aftermarket HSF and a fan on your NB and RAM.

Here are my settings to help you get started but of course everyones equipment is different so you will have to find your sweet spots and im really happy at my 3.6ghz sweet spot :p.

FSB - 420
Vcore - 1.125
RAM Ratio - 1:1
Ram voltage - 1.8
FSB VTT - 1.2v
CPU PLL - 1.5v
NB - 1.28
Other settings are just set to manual stock defaults

Hope this helps,
-Bryan
 
Then you have some work to do. The stickies are guides, not cookbooks. There are so many variables in solid state electronics that cookbooks will not work. Two CPU dies cut from adjacent places on their wafer can have very different characteristics. Nearly all the choices that you make matter.

You have two very different choices: you can blindly plug and chug or you can spend some time doing research.

If you are going to plug and chug, at least get a good cooler. Here are two for less than $50:
