I have two radeons in crossfire, and I accidently flashed this card with the wrong 4850 bios. The closest bios I can find is http://www.techpowerup.com/vgabios/54436/Sapphire.HD4850.512.090618.html but it uses hynix memory and my card isnt fully stable with it. The card I have uses samsung memory. I had a backup of this bios a long time ago but I can't seem to find it now. The label on the card is as follows: PN 288-2E104-D01SA SKU# 11132-35 Any help would be appreciated.
