Volts, on my 6800gs agp

[Firebat]

So i have a BFG 6800gs AGP card. It unlocked to 16/6 from the original 12/5

It overclocked to 415/1.15ghz

Now i want to get the core frequency to 425 stable, i wont go any higher than that.
Short of voltmodding with solder, how can i increase voltage on this card?

Thanks in advanced.

Im also aware of the Risks involved. So please don't post just to warn me.

Temps are also very good. Almost always under 50c

bios mod.

mod a 6800 ultra bios to your liking and flash it to the card.
