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.

Voltmodding guidelines: CPU and DDR2

Although I’ll be showing you how to volt mod this motherboard I’m not claiming to have come up with where and how to apply them, these modifications were done with the information available in this forum thread at XtremeSystems.org.

CPU core voltage mod

Solder on the marked side of the capacitor a 100KOhms trimmer to ground and trim it to its MAX resistance (100KOhms). This mod allows us to alter the CPU core operation voltage. The highest option we could choose in BIOS is 1,635V which comes down to under 1,6V when loading the CPU. This mod provides us up to 2V before over voltage protection jumps in. This is how we modded the board:

DIMM (DDR2 RAM) voltage mod

Although the board already provides up to 2.65V, extreme benchmarking might require for even more voltage on the DDR2 memory. For this mod to work, you need to solder a 100k trimmer from the red point to ground. This is how we did this mod:

After the modification VDDR2 goes all the way up to 5v.
