480 nitro+ 4gb samsung memory bios

I've been trying to get my 480 cards in order, since with the bios I am running I keep getting tons of incorrect shares. I did browse the forum, especially Jukebox's thread, but I believe his bioses wont match my cards. My cards are 11260-01-20G.

Anyone to send me a link of some good bios for my card, or just let me know what the best strap settings are, so that I can prepare my own bios?

Thanks
