So around 2-3 years ago i had a Sapphire 4770 blue pcb with artic cooling solution. From day 1 the stock clock of 750mhz was not stable, resulting in minor artifacting , soon after i got a 4890 and forgot about the card. Now i am building a rig out of old parts for a friend and figured ill try the 4770 again , downclocked the card from 750 to 650mhz and unigine benchmark was suddenly artifact free. So i figured if the difference is so minor, it cant be a completely broken card. so i downloaded trixx and upped the voltage from 0.95 to 1.00 and viola 750mhz ran flawless. now trixx is acting a tad picky, sometimes applying voltage, sometimes defaulting, and wont keep the setting when restarting the computer. I hoped someone could edit my bios to up the voltage so the changes at permanent. Ive uploaded it below http://www41.zippyshare.com/v/33604357/file.html Also are there windows solution out there to flash these custom bios'? Thanks in advance!
