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)
I run an AMD r9 290 sapphire.
update to latest AMD drivers. Then try again.
can't help with xfx. never touched that flavour.
Follow the links to the youtube video for some help. There is also a link to AMD's auto driver check and download.
http://spreadcoin.info/downloads.phpThanks for the tip, but with these problems I handle easily.
In this case, were used a farm, working on darkcoin, with the best settings and drivers for maximum performance.
Only changed the program-miner - "spreadminer".
HD7970, R9 270X, R9 280X - involved in work on the first try. But the R9 290 in two different system blocks stay with exactly the same errors.
Perhaps the reason is that I have Russian version of win7 Ultimate with Russian drivers.
There will be time, will try to collect from source miner directly for this machine, and while they may produce a different currency.
