dont try! this is old miner and is very buggy. it has not been updated like half a year
Which miner do you recommend?
The fastest AMD x16r miner that I know of currently is Kl0nLutiy's fork of SGminer. He's got a thread here, look it up.
It's nothing formidable just yet (x16r could be massively more optimised for AMD hardware) but it's the fastest I found anyway. Well, probably the fastest you could obtain using stone-age SGminer kernels.
