Raising Voltage

Raise the CPU core voltage. This may be referred to as "Vcore Voltage". Raising your voltage beyond safe limits can quickly damage your equipment, so this is the most finicky and potentially dangerous part of the overclocking process. Every CPU and motherboard can handle different voltage increases, so pay extra close attention to your temperature.

• When raising your core voltage, increase it in 0.025 increments. Any more and you run the risk of jumping too high and damaging your components.
• Run a stress test. After your first increase, run a stress test. Since you left your system in an unstable state in the previous section, you are hoping for a stable stress test run. If your system is stable, make sure that temperatures are still at an acceptable level. If the system is still unstable, try lowering either the multiplier or the base clock speed.
• Return to either the base clock or the multiplier section. Once you have managed to make your unstable system stable through increasing the voltage, you can go back to increasing either the base clock or the multiplier, depending on which you are trying to overclock. Increase them in the same small increments, running stress tests until your system becomes unstable again.
• Since the voltage settings increase temperature the most, your goal should be to maximize the base clock and multiplier settings to get the most performance out of the lowest voltage possible. This will require a lot of trial and error and experimentation as you try different combinations.
• Repeat the cycle until a maximum voltage or maximum temperature is reached.Eventually you will hit a point where you can't get any more increases, or your temperature is nearing unsafe levels. This is the limit of your motherboard and processor, and it is likely that you will not be able to progress past this point.
• In general, you shouldn't raise your voltage more than 0.4 above its original level, 0.2 if you're using a basic cooling system.
• If you reach your temperature limit before you hit a voltage limit, you may be able to eke more increases out by improving the cooling system in your computer. You can install a more powerful heat sink/fan combo or opt for a more expensive but much more effective liquid cooling solution.
