Hi,
I use Gygabite R9 290X for mining litecoins and feathercoins and I only can get around 400 kh/s effectivelly. I use cgminer 3.7.2. Settings in cgminer are:
“intensity” : 13, “vectors” : 1, “worksize” : 256, “lookup-gap” : 2, “thread-concurrency” : 32768, “gpu-engine” : 950, “gpu-fan” : 40-100, “gpu-memclock” : 1250, “gpu-powertune” : 20, “temp-cutoff” : 97, “temp-overheat” : 95, “temp-target” : 90,
“api-port” : 4028, “expiry” : 120, “failover-only” : true, “gpu-threads” : 1,
“log” : 5, “queue” : 1, “scan-time” : 60, “temp-hysteresis” : 3,
“scrypt” : true, “kernel” : “scrypt”, “kernel-path” : “/usr/local/bin” }
If I raise intensity, mining speed raises up, but there are a huge amount of mistakes then and effective mining drops to around 20-30 kh/s. I think that with this video card effective mining speed should be around 800-900 kh/s. I use newest video card drivers, I've tried number of cgminer settings, but it's allways the same. Someone can help me?
