all ocing is, is the luck of the draw. sometimes you get a really good chip that can go really far, like this one. other times you get a chip that hardly goes anywhere at all.
i have only OCed one cpu but i have it down to a science, there is just a check list of things.
1. Raise FSB
2. Run into stablity raise Vcore\lower HT for AMD CPU's
3. Still run into stablity, lower ram
4. More stablity issues i just raise the Chipset voltage
5. your chip\motherboard\ram cant go any higher
