6xx SERIES BIOS MODDING

Lets be honest, after NV putting their foot down the other week it couldn't be any less fun atm
Could be a handy little tool if it allows you to set different voltage limits on the LTG/SOC/Classy

From what I can gather the voltage is restricted to 1.212v
so how true that is time will tell.

is this bios tool out for dl yet?
Just seen this on xtremesystems.org looks like it works as far as it goes but we need the user variable options.
At least the OP is still active and answering questions

^^thanks for the link, just tried it and it does indeed work all you need is this tool and nvflash, everything can be done within cmd in windows and only took me all but 5 mins to do.
It unlocks power limit to 150%, fan speed to 100% and boost voltage is now 1.212 by default.
My default boost clock is now 1296Mhz which is still a bit too much for my 660Ti to handle so I am running -10 offset, giving final boost clock of 1280Mhz with vram at 3700Mhz, whereas before the core could only manage 1241 or so. Been testing with heaven bench, 3dmark 11 and crysis and so far no crashes yet. Very happy with the results.
One thing worth noting though is that due to higher voltage the temp will be higher also, if it gets too hot you might even end up with slower final clock so make sure your cooling is good. Although with my Galaxy 660Ti fans at full blast the temp barely touches 65C.

5 mins of work is hardly any hassle at all
. Save bios -> unlock -> flash it was the easiest mod I have ever done, no need to mess with figures in Nibitor, too. Mine doesn't really clock that well but the extra voltage can really make a difference on a decent clocker.

Isn't it suggested that running the GTX 6XX line at over 1.75v can lead to degredation though?
I'd be tempted to try this, but my 680 runs at 1280mhz boost (KFA2 one), so dunno if there's much point (the cooler can't keep up with it as it is anyway)

While I see your point, My 680s (both of them) with volt modding will run at 1450Mhz+. For benching reasons, this is sweet but for gaming, this isn't ideal. The locked memory volts are still what hold the 680 back. My temps under water never go above 50C, so would be nice to push this for benching only. For every day clocks, I run 1350Mhz with ~1740Mhz memory.
