"The 7A being based on the 7C I doubt anyone can get 1.7v with the Northwood P4. In order to add more voltage it would require quite a lot of rewriting some portions of the bios. I do not think Annamaria, myself or even Mr Natural have the ability to do it; at least not without putting in a huge amount of work.
To clarify: the bios does go up to 1.85v, but only for the willamette P4. With the Northwood, the maximum voltage is 1.7v, and it is not recommeded to go over that."
