k so i was reading i can flash my 6950 to 6970 bios unlocking shaders. i have a sapphire 6950 2gb. so i figured id give it a try. found the switch by crossfire connector. it isnt labeled so i left it where it was had to admin to dos then ran atiwinflash -unlockrom 0 then atiwinflash -f -p 0 (file name of downloaded rom for sapphire 6970) which i downloaded from (http://www.techpowerup.com/vgabios/88845/Sapphire.HD6970.2048.101124.html
) nothing worked. so i shutdown switch the switch to the opposite position it was in and rebooted. repeated the previous steps and it said that it was complete in otherwords and i should restart. restarted. blue screen. tried to use hdmi and dvi ports. no luck. hard power down. flipped switch back to factory position. booted up. says i still have the original amount of shaders and original bios. also read that for some reason u cant unlock some cards and that there is random luck involved? lolololol. dont understand y that is but anywho. is this one of those situations? please advise. thx.
