Hi guys! I recently bought Sapphire R9 290 Tri X 4GB OC, and after few days it start Black Scree. I could not enter in any game, the screen freez and start Black. I try all drivers from 13.12 to 14.8 and the problem was same. Yesterday I contact Sapphire Support ( Many Thanks ) and open a new Ticket about my problem. I send them my Bios Information, and they say that they have new Bios Version for my GPU. They send me both new VBIOS and instructions how to flash my card. After i did successfully flashed to new VBIOS, no more freezing and Black Screen any more. I am playing Battlefield 4 and other games without problems. I see that many of you have Black Screen problem so maybe that can Help You. Once Again, Many Thanks To Sapphire Support !!! If someone want I can attach VBIOS and instruction they send me.
