I was cleaning some files in my computer when I found this one that I saved several years back. Unfortunately, Office 2007 (trial version) cannot open the file because it disabled VBA automatically so I had to look for the original source which I still found it from
MadShrimps forum. This excel file will give tremendous powers to owners of entry level motherboards where the BIOS doesn't contain option to adjust voltages. All you need is a pen with conductive ink or a pencil to short some pins in your processor and something to cover or hide pins in volt modding.
In no way, istorya.net or the thread starter will be responsible for the damages brought by the volt mod to your processor. You do this at your own risk, I'm simply providing you tools in case voltage becomes a limitation on your motherboard. Some screenshots:
