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.

Hi,

Usually it's because the GPU is defective or unstable at that setting.
Since you don't get that with lower settings, I'm suspecting the card cannot support that overclock.
Did you monitor the GPU temperatures when litecoin mining ?

Not with those settings, but I'm positive that after I start mining with those memory settinsg etc. my temperatures won't even go over 90C that quickly, as I said, it's after just a few seconds that I start seeing the artifacts.
With the other settings (safe) the GPU temperature is about 75 degrees celsius on average.

Also, this GPU has a very good aftermarket cooling and I see other people getting stable results with the exact same settings with the same GPU where I get these crashes.

So, yeah...
