I thought this was kind of funny because Tom's had a terrible time trying to get their Phenom II's anywhere above 3.6Ghz. But at least they hit 4Ghz now! And on an air cooler that performs worse then the Xigmatek S1283. This might be useful for any of those swapping from intel to AMD.
Hopefully anyone interested in overclocking an AMD processor now has enough information to get started, whether it remains just simple multiplier-based overclocking within AMD OverDrive or more extreme overclocking adventures. Remember, results and exact steps will vary from system to system, so do not attempt to just copy our settings, but rather use the guide as an aid to discover the capabilities and limitations of your own system. Take small steps, monitor temperatures, perform stability tests, and use as little voltage increases as necessary. Learning safe shortcuts will come with experience, as making rash jumps in frequency and voltage is not only the wrong approach to successful overclocking, but it’s also one way to damage your hardware.
The last tip with which we will leave you is to be aware that there are quirks and specific tweaks that will apply to individual motherboard models, so it is a good idea to search out discussions related to your exact motherboard model and revision. Advice from experienced enthusiasts who have "been there and done that" with your same motherboard
can help avoid or overcome the pitfalls you may encounter with your own system.
