Hi, I just flashed my Sapphire 5770 Vapor X with the official matching BIOS from Sapphire's website and since then under 3d load (game etc) it wont use the correct 860/1200 and instead runs at 600/1200 with 1V. It still idles correctly at 157/300 with 0.95V Ive googled and flashed all available Sapphire Bioses here (and an Asus one) with same result. The card still underclocks even in a different freshly formatted PC with no previous AMD drivers. How do I make it run like normal under load? Ive found RBE but not sure what to do even though I read the tutorial. Heres my card and the official Sapphire VaporX bios I flashed to. I guess I need to edit the Powerplay state thing in the BIOS somehow ? I dont ever remember seeing it run at 600/1200 before anyway, it was either idle 157/300 or in gaming load at 860/1200 (or whatever I OCd to in MSI Afterburner), there may have been the 400/900 for movies but I definitely dont recall 600/1200 for anything. Edit: I forgot to say I didnt save the original BIOS as I figured official bios = good. Ive had same powerplay problem subsequently with all the techpowerup Sapphire bioses anyway.
