Reviving and Volt Modding an Abit AW9D-Max Motherboard

Howto by geoffrey @ 2007-01-24

The overclock ability of PC hardware is known for more then a decade now. As the market seemed to ask for more user friendly ways to overclock, manufacturers came up with ideas like dipswitches, softmodding through BIOS, asynchronous bus functions, etc. Though the risk stays the same, and once you run out of luck you might find yourself paying another $200 for replacement parts. Today we take a look on how we revived our motherboard after a failed BIOS flash, followed by supercharging it for extreme performance.

Voltmod: MCH/PCIe & FSB

Voltmodding continued: MCH/PCIe and FSB

There're situations when the chipset might limit your overclock because of the simple fact that it has hit its highest stable speed. Though the abit board already allows us to go up to 2V, the most extreme people out there found it useful to even add more voltage.

If you want to mod the MCH/PCIe voltage, add a 100k trimmer between the red point and ground. In the middle of the first picture below you can see our MCH voltage mod, on its right side the FSB voltage mod. The second picture shows the location of the trimmers we've used.

The BIOS doesn't allow us to adjust the FSB voltage. It's told that higher FSB voltage might boost the FSB overclocking a bit. Connect a 50k trimmer between red point and any ground if you want to change the FSB voltage.

Hipro5 designed this mod to give the MCH voltage another boost. Soldering a simple wire between both green spots allows the voltage controller to lose less power through the PCB lanes. The thicker the wire, the better.
