nvflash -4 -5 -6 bios1.rom
nvflash -4 -5 -6 bios2.rom
it works on all drivers version even the latest.
This is incorrect. The driver hooks into the card and limits it to .963 mV The OP in this thread will even back me up, which I helped gather info for.... If you say different then you do not know what you are saying. While yes you can flash a bios with a higher minimum voltage the driver knows it is a gtx 590 and will lower it to .963 mV. There are formal requests over at the nvidia forums to remove this limitation ever since the two reviewers blew their cards on camera (on purpose). Masked can back me up, as he had access to these cards even before they were released and saw them before the limitation was implemented.
The old 267 drivers are NO LONGER on the nvidia website. They removed them (we can only guess) to disallow people to overvolt the 590's.
Start at this page to get them, I do not remember the correct version exactly, just that it was 267.xx: http://www.laptopvideo2go.com/drivers/17?dev=1088&sub=83A31043

What does the voltage lock down and max voltage mean?
Around driver release 267.91, we lost the ability to increase voltage with 3rd party utilities. nVidia even condone overclocking at the start (although small) it was enough to overclock about ~5% going on their recommendations. It seems they went back on their original claim and decided to remove everyones ability to overvolt.
The last driver to have the ability to increase voltage is 267.85. In fact, while normally they keep a back log of beta drivers in the archive. You will have a hard time to finding them anywhere on nVidia's site, its almost like they didn't exist.
While we only discovered this recently, it seems that not only did they remove your ability to increase voltage, they put a maximum voltage in the driver, for those of us who know a work around) which overrides any BIOS you have flashed on the cards. Thats only in the more recent BIOS's, the theoretical max voltage is driver 267.85 is still the reference GTX 580 max of 1.201v.
