Here's some quick tips that will help get you started I hope. First, you are gonna want to disable Cool & Quiet as well as C1E and all Spread Spectrum options in the BIOS. They tend to make your overclock unstable especially as you go higher on the frequency. Second, Enable Load Line Calibration as this will help prevent vDroop when your CPU is under load.
Now you are gonna want to start with a simple Multi change to get started, try pushing your Multi up a couple notches so that your CPU is at 3.6-3.7GHz, I find that some chips can run those speeds with stock volts and some can go as high as 4.0GHz if you have a golden chip. Run Prime95 for a minimum of 10 hours but for a quick test you can try running IBT for 20 runs if either fails then you are gonna have to increase the volts.
Now as far as voltages are concerned I know there are alot of volt options in that BIOS but the ones you are gonna want to focus on are "CPU Voltage" and 'CPU-NB Voltage' and possibly later the 'DRAM Voltage". CPU-NB refers to the IMC and by overclocking this you get better performance overall than if you just increase your CPU speeds. You can increase the CPU-NB frequency to 2600 which is a good start, I was able to do that stable at 1.25v. Try to keep HT Link as close to 2000MHz as possible because it can cause instability if you go too high.
Obviously every chip is different, settings that work for one might not work for another. It is beneficial though to read as many guides as you can to gain knowledge before you get your feet wet. Start small and work your way up. Make sure you have a good aftermarket CPU cooler because stock cooling isn't gonna get you anywhere. Max CPU voltage on these chips is 1.5v for 24/7 some will say 1.55v is fine but I try to stay below the first number. Also, keep an eye on your temps, Max temp is 62Â° but I have read that the higher you go over 55Â° the CPU tends to get a bit unstable. Now I've never noticed that but good to know just in case.
Anyway, I hope this info helps you out a bit. Just start in incremental steps and you'll be fine. If you have anymore questions just ask. Good luck overclocking.
