Start Windows and then download CPU-Z. It can be found here: http://www.cpuid.com/softwares/cpu-z.html. Look for your CPU volt, to the right of "Core Voltage". You can also check the bottom, after your multiplier for later use to calculate your CPU speed. Write these numbers on a piece of paper or similar. Only you have it on hand for later use. Prepare yourself by finding a manual profile for the processing unit (CPU) in the bios .. In my case, it is under Advanced and then under "JumperFree Configuration". And at the "AI Overclocking" I choose the profile manual.
Here it begins
Start by finding somewhere where you can set your "CPU Vcore Voltage". When you made it so, enter the volts that you took from the "Core Voltage" in CPU-Z. If you want you can now save and restart the computer and go into Windows and check CPU-Z if it looks right. It is normal that the voltage does not always end up in exactly the same speed. Once you've done this so you can restart your computer again and then go back to bios again.Look now for a profile where you can set your CPU frequency. This is what you change to raise your CPU Mhz . Start by increase 10-20 and then restart your computer. To do so, just select the CPU Frequency and then you just need to enter your speed. Once you've made it so you save your changes and then restart the computer to go back into Windows. Now, start CPU-Z and check if your Mhz has changed.
Keep track of the temperature!
You can do this through several different options, I recommend that you use a program called "Real Temp". Otherwise, it´s easy to check temps in bios, but then, youre not able to see what your CPU temperature is it´s stressed. A last option is if the Intel gadget if you use windows 7 or Vista.

The last thing you should do is to stress your CPU to see if your CPU is stable or not.To do this, you can use the Intel Burn Test, it can be found here> http://downloads.guru3d.com/IntelBurnTest-v2.3-download-2047.html. If your CPU does not seem stable, you can go back to bios and test with different settings and then try again. Clear signs that your CPU is not stable is that for example, you get the BSOD.
