It was terrible! guys, I flashed my reference zotak gtx580, downloaded the bios from techpowerap zotak to 580, not old backup, and horror!, the computer was switched on with 2 "peak" s, and not as earlier one, and a bunch of artifacts even in dos, then pierced six different versions of bios for zotac, but to no avail, the card only in safe mode in 16 colors. HELP people, I burned it? AAAAAA !!!!!!!!! At first I kept the bios prog hcp-z, but the utility of the Fermi-inhibitor, did not take a file and only. Bin downloaded from the site for techpoverup zotak. I edited the lower the maximum stress appears at 1.150 to 1.050, then save. Flashed in dos by typing nvflash -4 -5 -6 fayl.rom old is not maintained, and gpuz originally removed. Meticulously flashed the bios with all eight of this site, 2 error of 57KB, with the remaining 6 to 81KB - without any changes, thought to be the main slot ps-e to flash (blue), and then from my 3pc and pierced originally in black, but rearranging, and ask a blue slot, nothing has changed. Pierced out of the DOS command nvflash -5 -6 file.rom , also from 3 to flash, flash, all successful, but on the map unless you can work in DOS, and then some artifacts.
