To set the CPU on full blast all the time, go to the BIOS and switch the clock speed multiplier from auto to manual. Then add the multiplier you want. There are so many in depth guides for how to OC a PC, but you just want it to be running at full speed all the time. You won't need to mess with the voltages. Also, unless you are doing something like heavy gaming, there is no good reason to do this. Your CPU is increasing its longevity and efficiency by down clocking when it isn't needed, just saying...
1. Restart PC
2. Mash Del key until BIOS shows up
3. Set CPU multiplier to 34x (100mhz)
4. Save and exit
