OK, I've taken some screenshots for you. I'll give you a quick run through.
Please take this as is, and im not responsible for any damage caused by this short guide. Overclock at your own risk.
I would also recommend doing a stress test on your CPU and seeing where you stand before beginning an overclock. For example, if your CPU is getting to 75C without an overclock then there are issues with your cooling and need to be fixed before overclocking. I would start at 4.2Ghz and work your way up from there. Stress test your CPU and see what temps your getting.
First step, go into the BIOS and Advanced Mode. Go to Advance and CPU Configuration, Disable Intel Adaptive Thermal Monitor.
Second step, Go into Advanced then CPU Power Management Configuration down the bottom. Once in there i disabled everything except for Turbo Mode and Package C State Support. Leave the CPU Ratio as is for now.
Third Step, Go into AI Tweaker, then DIGI+ VRM. Once in there, Set CPU Load-Line Calibration to "High" CPU Power Phase Control to "Extreme" and CPU Current Capability to "120%". Everything else remains the same.
Fourth Step, Change the CPU Voltage to Manual Mode and input the voltage you want. I'm using 1.250V and it's stable at the moment at 4.3GHz.
Fifth and Final Step. Go to Advanced\CPU Configuration\CPU Power Management Configuration and change the CPU Ratio to whatever you want. Basically X this number by 100 to get the MHz that you want so 43 x 100 = 4300Mhz or 4.3Ghz.
As i said earlier, Overclock at your own risk. But keep in mind, I'm air cooled so you should be OK if your under water.
If your PC Fails to boot to windows, you might have to wind down the frequency.
Use a Benching program to stress test your CPU Before and After the Overclock. 80C is getting a bit warm, if your hitting 90C you'll need to back off.
