Voltage question - please help!

My Abit IP35 Pro and 4x1GB Corsair TwinX PC6400 CL4 arrived today.

I notice the ram says 2.1 V, but the default memory voltage in BIOS is lower than this.

What do I need to do?

Raise DDR2 Voltage to 2.1v.

Will the IP-35 Pro POST with this memory at default volts, in order to let me raise the DDR2 volts from the BIOS?

Should do. It just needs the +0.3v to perform correctly / at rated speeds.

My Crucial Ballistix PC8500 runs at 2.2v default.

Yep, that's the whole point.

I presume you've got the 4-4-4-12 stuff? If so then it's only rated at these timings at 2.1v - at the DDR2 standard of 1.8v it'll only do 5-5-5-18.

The SPD will report the 5-5-5-18 timings to the mobo so it all works fine at the standard 1.8v. You then raise the voltage to 2.1v and manually override the timings to 4-4-4-12 and you're sorted.
