I think the L7 is for 1.85, and all connected gets you to 1.85V. But you might not need `1.85 for this. Does your board allow to to manipulate the VCore? Probably not. Well see if you can hit 1 ghz with just the stock voltage, it will run cooler. Since your cpu runs at 1.6 default anyways. I dont know how easy it is to hard mod it to say, 1.7, but 1.85 would make it somewhat hotter.
