I made some headway last weekend. I gave up on Linux after being unsuccessful with BAMT and SMOS. I installed Windows 8.1 and was mining in 30 minutes. Amazon still hasn't shipped my 1300W PSU so I'm currently only running 5 GPUs with an 850W and 1050W. Out of the box they were all running around 860 kh/s. I've spent the last couple evenings tuning and things are looking promising. Things I learned along the way that seem to have helped: 1. Use Catalyst 13.12. The 14.2 beta drivers were very unstable. 2. Don't bother with Trixx. Install MSI Afterburner and use the settings shown on this post (link). 3. I don't know if this helped or not, but I'm currently running with the bios switch toggled up (toward the end with DVI ports) .. Here are my current settings. "intensity" : "20,20,20,20,20", "xintensity" : "0,0,0,0,0", "rawintensity" : "0,0,0,0,0", "worksize" : "512,512,512,512,512", "kernel" : "ckolivas,ckolivas,ckolivas,ckolivas,ckolivas", "lookup-gap" : "2,2,2,2,2", "thread-concurrency" : "25601,25601,27401,25601,27401", "shaders" : "0,0,0,0,0", "gpu-threads" : "1,1,1,1,1", "gpu-engine" : "1040,1020,1020,1040,1020", "gpu-memclock" : "1500,1500,1500,1500,1500", "gpu-memdiff" : "0,0,0,0,0", "gpu-powertune" : "20,20,20,20,20", "gpu-vddc" : "0.000,0.000,0.000,0.000,0.000", "temp-cutoff" : "90,90,90,90,90", "temp-overheat" : "85,85,85,85,85", "temp-target" : "78,78,78,78,78", "auto-fan" : true, "api-mcast-port" : "4028", "api-port" : "4028", "expiry" : "1", "failover-only" : true, "failover-switch-delay" : "60", "gpu-dyninterval" : "7", "gpu-platform" : "0", "log" : "10", "no-pool-disable" : true, "queue" : "0", "scan-time" : "1", "tcp-keepalive" : "30", "temp-hysteresis" : "3", "shares" : "0", "kernel-path" : "/usr/local/bin", "device" : "0,1,2,3,4" }
Yesterday I bought 4x Sapphire 290 TRI-x after few tests with basic core and mem clocks I ended up with 700kh/s. So I have decided to test your shared configuration,which ended up with very nice 900-910 kh/s I had to delete these rows in config: "xintensity" : "0,0,0,0,0", "rawintensity" : "0,0,0,0,0", and had to lower gpu-engine to 1020. In case I leave it at 1040, temperature rocket sky to 85, which is too high for me in long term. So I want to say BIG THANK YOU. Thank you dloganbill for sharing your tips.. Sending greetings from Czech republic.
