I have 2 reference r9 290 cards each with the corsair hydro HG10 bracket and H60 coolers. I would like an OC bios for these cards like I used on my HD6970s before, but I have been unable to find any or a tool to edit the stock bios. I have heard that the Sapphire trix-oc and MSI gaming cards use the reference board just with better coolers and their bioses work on reference boards. Is this true? If not is there a OC bios for my liquid cooled 290s?
