Hello, i got this card from a amateur miner, who tried to flash bios, messed up silent mode and bricked turbo, didnt know how to fix it so he sold it relatively cheap. Unfortunately i can't find original bios for it, on techpower website there are only e411, and e426 are unverified, i've tried them, one sets fans in some weird off/full on mode, second one doesnt work at all. Does anyone have this card and could share both bios files for it, or knows where i can get them, cant find them anywhere?
