Made my own,would have loved if someone else did it,no tools support the card yet.
580 GTX 3GB(GV-N580UD-3GI )
modded BIOS for those who want it.I looked for this BIOS and there was none to be found on the net.So I did one up.
Always backup your own BIOS first and just add to files on bootable drive incase things go wrong.
Unzip and copy files to a boootable drive and just type in when booted.
nvflash -4 -5 -6 gf110.rom .
And it will update all cards from single to 4 GPUS.
What this Bios does is unlock voltage from 1.15mV to 1.213mV
