I'm using a .bin created with 14.4 drivers but I had to update to 15.7.1, now is working without HW errors and an R9 280X.
Jeah! Same here!
I work whit the new AMD Driver and hashrate is now better!
Edit: I put the amdocl.dll file from catalyst 14.4 direct to de miner folder, and it works whit my ASUS 290X DCU2 whitout HW Errors i have 6 Mh/s whit 850 Mhz GPU to 1250 Mem clock...
