Wow, that's a bit extreme for anything other than trying to break records under LN2.
Its actually relatively simple and not just for world records. They are reaching 1400 base clock with a very tiny voltage bump ON AIR cooling. The power board is not necessary you just need to do the VID mod which requires a 7 pin dip switch (these cost about 50 cents) then you soldier a few wires.
only issue is one thing that has to be soldiered (vid 6 to vid 7) is rediculously tiny. You'd have to have a microscope, the absoultely correct soldering tool and a hand that doesn't shake.
Then you enter the voltage you want by setting the 7 switches on the dip switch to either 1 or 0. There is a table of correct values for a multitude of voltages but for 1400 base clock you seem to only need around 1.3v. If your using water cooling you could probably reach a bit higher.
I will probably 'attempt' to do this after a few months when i get bored of the card or angry at high clocking 670's. If I do so i'll make a detailed guide what i did. a 680 at 1400 is definetely gonna make it one of the fastest 680's in the world and make me feel like the 680 purchase wasn't a total waste. If i had water cooling i'd strive for 1500 base clock.Edited by ilikebeer - 5/13/12 at 9:37pm
