I've never had so many problems with a graphics card in my 15 years of building and maintaining PCs. Almost a year ago, I recommended this card to my cousin, whose 6850 bit the dust after a couple of years. The R9 380 will run a few select games perfectly, while on others it will black screen a couple of minutes in the game. The monitor loses signal (tried both HDMI and DVI), the sound continues and after a while the PC hard locks. I've tried literally everything, including dismantling the entire PC and rebuilding it from scratch, days of stability and stress testing, to no avail. The system is an i5 2500k on a Gigabyte Z68 mobo, with a beefy Corsair 650W PSU. It's rock solid - tested for 24 hours via Prime, Memtest etc. I've even stress tested the card via FurMark - no issues. Games like Total War: Rome 2, Endless Space, Endless Legend, the latest Civ games, Galactic Civizilizations 3 etc. are unplayable due to this issue. Even older titles, like Mass Effect 2 can't even launch (crash after a few seconds of loading a game). Other titles work fine for hours on end, like Oblivion. The card works flawlessly on desktop usage, both in Win 7 and Win 10. The most 'stable' (if I can call it that) driver appears to be 15.11.1 beta. With it, some of the aforementioned games are playable for a few minutes, at least. I've tried the various fixes posted online, including disabling low power mode completely via the registry. Apparently this is a widespread issue, but AMD has yet to release a definite fix. It's been a year since my cousin got this card, he can't play his favorite games on it and I've spend weeks troubleshooting it. Should I just tell him to sell it and go get an Nvidia card? Or is there a fix I might be missing?
