I have two graphics cards R9 290 (XFX and Sapphire)
But they don't want to work with the mining SPR, although perfectly produce any X11, n-scrypt.
Spread-GPU-miner and spreadcoinx11-sgminer-girino behave exactly the same. The Assembly is the kernel (*.bin) and all. Stop.
All other video cards work fine with both miners. (HD7970, R9 270X, R9 280X)
