Here's a quick overclock guide to 4.4GHz:Warning: Spoiler! (Click to show)
1. Set "All Core" CPU Multiplier to 44X
2. Set CPU cache Multiplier also called the Ring bus multiplier to 35
3. Set Fixed CPU Vcore to 1.25 -1.30v
4. Set CPU Cache Voltage also could be called Ring Bus voltage to 1.20v -1.25vv
5. Set Vrin also called "CPU Input Voltage" To 1.9v - 2.1v
DO NOT and i repeat DO NOT mix up the "Cpu Voltage" and the "CPU Input Voltage". One is for the CPU and the other for the On Die VRM's.
Save and reboot into windows.
Use your favorite Stress tool. I used IBT on High and monitor temps with Realtemp or some other monitoring program.
Run it for 10 Runs or 20 or whoever you feel comfortable with. I run it for 10 usually. If it doesn't blue screen you after the 5th run you could assume you're stable. Again run it for as many times as you want. Get through 10 or 20 runs and no crash? Congratulations you're stable and you can fine tune.
Some extra's. Some bios' will add in a little offset voltage for both the CPU and Cache. Mine was .8 for the CPU and .4 for the Cache. If that happens put the lowest setting you can. Not "Auto" but .01 for each.
