Gigabyte GA-6BXC

Slot 1 mainboard from Gigabyte with 440BX chipset.

Voodoo 3 compatibility

Revisions lower than 2.0 of this board can't supply enough power for some graphics cards such as the Voodoo 3. The 3.3 V voltage regulator near the AGP slot will eventually fail. Newer revisions apparently have a "Voodoo fix" jumper which connects the AGP slot directly to the ATX power supplies' 3.3 V rail.

AGP 3.3V to ATX power connector mod

Only required on revisions older than rev2.0. The mod instructions were initially published for many affected mainboards by nickles.de in this article. Unfortunately, when following nickles.de's instructions for the GA-6BXC, the system will no longer boot. As was pointed out in the nickles.de comments, this is due to the picture instructing to run a wire from the ATX +3.3 V connectors to the wrong voltage regulator (1.5 V). This can easily be corrected by running the wire to the correct voltage regulator instead. When performing this mod, I would recommend to always check the voltage regulator against mass with a multimeter.

Corrected mod on rev 1.9
