The manual says .1v increments for the CPU_NB and RAM...my OCZ DDR2-1150 runs at 1.8v 5-5-5-15 but I would like to run between 1.8v and 1.9v and not just jump to 1.9v. :P It's probably a misprint, but I'd like to know before it's too late. I'd also like to run no more than 1.35v -ish on the NB, I'm not going to run 1.4v 24/7. Thanks.
This is an image I snagged off of some site.

When you set the System Voltage Control to Manual you can increase the DDR2 Voltage by .1v increments up to +.6v. From the image you can see the auto voltage was 1.8v so it could go up to 2.4v.

I don't know what the auto voltage is for northbridge but it can go up +.1 to +.3 volts. It's the same for the southbridge.
