Currently I'm using Catalyst Software Suite 13.12 (make sure to update from AMD's site if you haven't already). I'm using the scrypt below to achieve 980 k/hash on my SAPPHIRE TRI-X OC 100361-2SR Radeon R9 290X, don't ever go by the dashboard in your pool btw, your real hash rate is from GUIMiner. Let me know if it works for you. Note that the Radeon R9 290 cards are not considered to be the best option for Scrypt mining, however with R9 280X cards harder to find some people decide to go for the more easily found 290 or 290X models. But unlike with Radeon R9 280X, the R9 290/290X cards have more specifics and could cause you some extra headaches until you finally make them work as they should and provide decent ... The first is stock settings 947/1250 which yields ~800Kh/s. The second is 947/1500 which yields ~900Khs/s. Anything in between and you reduce your hash rate. SOME 290 are capable of 1500 memory clocks, but I would say the majority aren't. 290x is about $150 more and only 10% faster. Check your GPU hash rates below. Although an ASIC can be built to provide optimal hashrates on an algorithm, the Graphics Processing Unit (GPU) is much more powerful than the CPU, and more flexible than an ASIC in their application. The GPU is the chip that enables graphics cards (often called GPUs for brevity in mining circles) to perform millions of repetitive calculations at the same time ... The Radeon R9 290x Tri-X graphics card mining profitability ratios, payback period for ETH mining and annual return. All based on live network hash rate statistics and ethereum prices.
