Hey there, I recently purchased a Sapphire R9 280X Toxic (10-05-2014) and am currently using it for gaming aswell as with mining litecoin. For optimal mining results I should set my overclock settings to 1160 Mhz core clock and 1875 Mhz memory clock (with power-tune 20).
However, when I do so and start mining I get a few artifacts really quickly (which is why I don't think it's a overheat problem, but it's definitely related to the clocks) and then my system crashes, well, my screen shows some vertical grey-ish lines and my system is irresponsive. I then have to manually shut it down by pressing the power button my HAF-X.
When I use other settings (1060Mhz Core, 1500Mhz memory) I don't get these. When I play my games I use the standard 1150Mhz core clock and 1600Mhz memory clock. I can go for hours playing these games and I never get crashes, the card keeps running cool.
I´m really hoping it´s a software related issue (BIOS or whatsoever), and I don´t think it's a overheating problem because, as I said, the artifacts appear after seconds I start mining. I also don't think it's faulty ram because I can use other settings without errors. However, I don't know much about these things so your opinion counts more than mine.
The artifacts look like this: http://gyazo.com/bab02a9450e47b9ea6199a9de78ce417
I'm using Catalyst 14.4
Bios and other info: http://gyazo.com/77872588c11f9f66db7d3bb40d1e5b96
Hardware:
CPU: AMD FX-8350 @4.6Ghz
GPU: Sapphire R9 280X Toxic
Motherboard: ASUS Crosshair V Formula-Z
RAM: 16GB Corsair Vengeance ram @1353Mhz
PSU: Cooler Master Silent Pro M2 850Watt
Ask me anything you want to know, I really hope I don't have to RMA my GPU or such.
