HOW TO VOLTAGEMOD YOUR BOARD:
The requirements are:
- Cooling paste (you need to take of the heatsinks otherwise you can't desolder the SMD resistor)
- Tweezers
- for each board; 4 x 12.7k resistor (high precision)
- soldering flux
- small solder
- thin tip soldering iron
- optional: anti static mat
First thing you do is take the blade out of the box it is in. Then you screw of the heatsinks, otherwise the heat from your soldering iron is transfered away from the resistor immediately and you won't be able to solder is off. Clean the board and the heatsinks from old cooling paste. If you have it use an anti static mat (I didn't).
Locate the voltage regulators:

Now locate the resistor you need to desolder:

The configuration of the circuit differs a little, but it is always the resistor next to the empty space and capacitor, marked '05c'.
Put some flux on the resistor, heat up both sides and use the soldering iron to push it off. It will most likely stick to the soldering iron so shake it of onto a peace of toilet paper or something that it does not bounce away. Resolder the two contact points with some new solder and put some flux on it.
Take a 12.7k resistor, fold it so that the two legs are about 1.5 mm apart. Cut them into the right length and rough up the legs so the solder adheres better. Solder the legs of the resistor.
Take the tweezers and hold the resistor on the two contact points. Use the thin tipped soldering iron to one by one secure the legs to the board.

After you have repeated this four times on each board, put new cooling paste on the chips and screw the heatsinks back on.
DISCLAMER: I am of course not liable if anything happens to you board, it is entirely at your own risk. Do first try it on one board and test it you before you do the rest of you boards.
