Boost the voltage of Intel Core 2 Duo


What is overclocking?


Overclocking is pushing your CPU to run at a faster clock speed than the manufacturer has it set at.


Lets Get started!

The first step is to enter your BIOS. To do this, boot up your computer and while it begins to post hit the Delete key.

There are two main ways people go about overclocking. The first way is by increasing your FSB by 10mhz at a time and running Orthos and monitory temps, and increasing voltage when needed.

So you've decided to overclock that Core 2 Duo processor you have. Issue is, even with all the proper overclocking software and the right heat prevention gear for your components, your processor still can't output the necessary voltage to get this thing started. Instead of simply throwing away your motherboard and buying a new one, through using a variation on the "pin-mod" overclocking technique, you can easily alter the voltage with just some electrical tape and conductive ink.

The Core 2 Duos bring the joy back for the Intel Overclockers with their easy to handle heat and ample of overclock head-room. However, the overclocking capacity depends as much on the motherboards paired with them. Some of the enthusiasts on a tight budget are stuck with a limiting motherboard , particularly in the voltage department. Well now here's a way out for you!

Until recently, your only option would have been to buy a new motherboard due to limits set on the voltage output. Now, through using a variation of the tried and true “pin-mod” technique, you’ll be able to bump your voltage up from using just two tools: electrical tape and conductive ink. This mod will work on nearly all of the Core 2 Duo CPU’s by connecting a few points with the conductive ink. In the past, these points where actually “pins” that you would simply bridge within the motherboard seating to achieve a similar overclock in voltage, but without them there, the process of overclocking becomes a lot easier.

You can basically over-ride the default voltage of 1.35v inherent on many of the Intel Core 2 Duo, E6300 to X6800, with a simple "pin-mod". Well yes, there are no longer pins on these LGA packaged precessors... in fact that makes them easier to modify! All you need is some electrical insulation tape and some conductive ink!

**As some CPUs come with a different default voltages such as 1.2875v, etc, using these mods will get you different results so I will be updating with more info for CPUs with different default voltages. For now, this is for 1.35v default.**


  • Overclock to 1.4v: You will need to connect the two pins together at row three, column’s six and seven.

(To get a slight bump to 1.4v, simply connect the 'pins' shown above with conductive ink. This is a direct representation of your Processor and not your motherboard socket, do take note!)


  • Overclock to 1.45v: You will need to connect two pins together, along with covering a third pin. Connect the pins together at row’s two and three, column four. Place a pin sized piece of tape over the pin at row four, column four.


  • Overclock to 1.5v: You will need to connect two sets of pins together, along with covering a fifth pin. The first set of pins are row’s two and three, column four. The second set of pins are row three, column’s six and seven. Place a pin sized piece of tape over the pin at row four, column four.


  • Overclock to 1.55v: You will need to connect the two pins together at row’s two and three, column four.


  • Overclock to 1.6v: You will need to connect two sets of pins together, the first at row’s two and three, column four. Then connect the second set at row three, column’s six and seven.


To facilitate precision, tape over the surrounding 'pins' except the ones you are trying to connect. For example, as shown below for overclocking to 1.4v


*NOTE* This tutorial/tweak is only the first draft. I'm sure it has plenty of errors. Please point them out in your comments as you see them, and I will make changes. Thanks !
