KillerRose,
8.0 Volts for a CPU is quite high!!! Anyway, I currently have the same combo, and my Blue Core 1Ghz T-bird is cooking along @ 1.34ghz @1.85V! These MBs are very stable, so you should be able ot attain speeds of 1.15-1.2+Ghz, depending on your heatsink/cooling. As for the bios settings, I use 10x133 myself, since my ram isnt the greatest in the world, but as KillerRose pointed out, set your multiplier to around 7 to start, and work your FSB as high as you can go and still have a stable system. Once you achieve the highest FSB, try rasing your multiplier in order to squeeze a little more speed. You may also wish to raise your core voltage to around 1.8-1.85V, depending on your cooling, in order to reach higher speeds.
