    Hello lue_85, here you have the bios for the sapphire hd 4770 blue pcb. Its the one you are asking for, the arctic cooling version, but with this you can only reach 860 mhz on mem, I think it is a bug, Im trying to solve it by using the bios from PowerColor 4770 PCS version, but I cant find it anywhere..

    thank you, maxigg, unlucky my hd 4750 has only 480sp,even try on hd 4770 bios, but somebody cracked 640sp. and about qimonda GDDR5 on this card, some site tested and it can't take to much OC, only about 900(3600)Mhz, so 860's limited isn't a big problem

    This GDDR5 is made to run on 1000mhz. On standard Shappire HD 4770 red one, ram go without any problem on 1 Ghz and more with some voltage juice.
    I have both cards at home, Shappire red pcb and blue pcb, and red one it is very good overcloker, for blue I can only gpu overclock and gddr to 863mhz I think.

    Anyone tried to contact Shappire?
