Yes, you reset your BIOS to stock settings, turn off turbo core, then go to your BIOS, it will show your voltage to left of the voltage, which is the stock voltage. This is what you want to start with. Mine was 1.308v then change to manual mode, click on that box and just type in 1.308v or whatever your stock voltage is.
Good luck and have fun. I hit 4.86 last night on my 8320. Well I booted at 5.1ghz, but temps were through the roof when I started Intel burn in test and had to stop after about 10 seconds. lol.
