Hey guys,
I have a problem which I'm troubleshooting for days, and still not solved.
I got R9 280X MSI 3GB, 12GB of RAM, i3 4160, ASUS H81M-E, PSU ThermalTake 400W

On this setup my last gpu 7870 2GB worked perfectly on NiceHash mining ZCash on Claymore's miner, when I set up 280X, there are problems income..
First problem was GPU #0 returned incorrect data! on Windows 10 WITHOUT OC, everything stock. I also tryed many drivers, 15.12, then lastest, everything the same..
Now I got another HDD and installed Windows 7 64bit(Basic theme, not aero), got NiceHash setted up, Claymore's ZCash miner, 15.12 driver for win7, and still the same. Then with lastest driver, same situation. Here I saw another problem, monitor goes off for 1 second and it says "Display driver stopped responding and has recovered".
Can anyone help me, what to do ? I tryed to underclock core and memory, It worked for about 6 hours without error and then it came again, I can't let it run for 24/7 without assistance. Also lower clocks get me about -20.000 sols than stock.
Can anyone at least give me recommendation for batch file for my GPU in this case ?

try v12.2b. If your card works with that version, might can be some r9 x80X related problem, because I have also "Display driver stopped responding and has recovered" popups with newer versions.

Thank you but I think I found a solution. I was googling a lot since that problem started and I found this https://steemit.com/mining/@felixxx/gpu-mining-equihash-undervolt-is-where-it-s-at
If you have same problem and same GPU, try this. My GPU is mining 1 hour without error or rejection on that settings, seems very stable.
I'll leave it mining for more to see if it's stable. All I need is stable rig because I won't be home to assist, restart or something.
Edit : Worked very stable for 2 hours and after that a crash.

My 6GB hd 7970/280x, even with claymore only detecting and using 3GB is getting 321H/s. Its undervolted to 1.12v as it is a very high end Sapphire Toxic card which originally was at 1.26v and underclocked to 1140mhz from its original 1200mhz, memory overclocked to 2010mhz.

I had the same problem as you and tried to mess with the clocks and voltage but that wasnt the issue. For me it was the temperatures. The card is fine as long as it doesnt get pas 72C. As it starts getting close to 75C the display driver starts to crash and eventually the PC reboots.

I increased the fan to always be at 60% and that way the temperatures never go over 66 or so. It solved the issue for me, mining for 50 hours without issue

PS: And yes, AMD Wattman is a pain, it always tries to restore your old settings, everytime I change something I have to uninstall drivers with DDU and reinstall them
