Last weekend I got Sapphire Hd 4870 1g Gddr5 Pci-e Qp. when found its GPU Clock seem always at 750MHZ, I tried to use RBE(ver 1.21) to fix the BIOS. But it shows the message : Unbale to find clock settings'Debug information'Get ClockPos Report 0'.
I do not know Why, Please HELP ME! I put the BIOS in Attachment List. BTW: when I used RBE to refix Sapphire Hd 3870 , did not see such bug.
