Having trouble finding information on DDR2, MCH, and FSB voltage.

I've got a Gigabyte P35 DS3R and a Q6600 @ 3.6GHz (400x9). The thing about the voltage adjustments for this board is that they're labeled as +0.1v, +0.2v, etc. I don't know the base number that they're adding to.

1. What's the default voltage for MCH/Northbridge? What's the max voltage for MCH? I heard it's 1.55v?
2. What's the default voltage for FSB? What's the max voltage for FSB? I heard it's 1.45v?
3. My DDR2 800 is rated at 1.9v. What's the max voltage that I can safely overvolt it to? 2.2v?

The max FSB that my board supports is 1600. Since I'm already at 400 for the CPU, I've already hit this limit. If I want to go higher than 400 am I going to have to:

1. Overvolt the RAM?
2. Overvolt the MCH/Northbridge?
3. I heard that I wouldn't need to overvolt the FSB value.

Around 1.5V is a pretty high, but healthy setting for the NB on most boards. The max I'd run DDR2 with no special cooling at is 2.2V. And I'm not sure on the FSB voltage, but overvolting it .1 volts shouldn't cause any damage.
