Voltage for PowerMac's DDR2 RAM

[GreenDice]

I am shopping for DDR2 PC-4200 RAM modules for the new PowerMac. There are modules with 2.0V while other say 1.8V.

What one should I buy?

Thanks in advance.

iirc the voltage given is the max voltage its rated for (why more expensive ram has higher voltage) and itll run fine at whatever voltage the power mac runs it at, but i'd definitely wait for canadaram's response on this one.

I just saw that Mushkin (more expensive than most) is rated 2.0-2.2V.

Is there a way to find out what RAM does Apple use in the PowerMac? I have not ordered mine yet and I want to have the RAM ready when the computer arrives.
