Does anyone have any suggestions on how I can improve this config for 280X GPU. I am particularly interested in the settings for keccak. All the other algos seem to hash very well. My problem with keccak, I'm getting at least 20% reject either job not found or stale shares. { "pools" : [ { "name" : "WestHash-Scrypt", "url" : "stratum+tcp://stratum.westhash.com:4333", "user" : "BTC_addr", "pass" : "x", "thread-concurrency" : "8192", "algorithm" : "zuikkis", "intensity" : "13", "gpu-engine" : "1100", "gpu-memclock" : "1500" }, { "name" : "WestHash-Scrypt-N", "url" : "stratum+tcp://stratum.westhash.com:4335", "user" : "BTC_addr", "pass" : "x", "thread-concurrency" : "8192", "nfactor" : "11", "algorithm" : "zuikkis", "intensity" : "13", "gpu-engine" : "1080", "gpu-memclock" : "1500" }, { "name" : "WestHash-X11", "url" : "stratum+tcp://stratum.westhash.com:4336", "user" : "BTC_addr", "pass" : "x", "thread-concurrency" : "8192", "worksize" : "64", "algorithm" : "darkcoin-mod", "intensity" : "18", "gpu-engine" : "1150", "gpu-memclock" : "1500" }, { "name" : "WestHash-X13", "url" : "stratum+tcp://stratum.westhash.com:4337", "user" : "BTC_addr", "pass" : "x", "thread-concurrency" : "8192", "algorithm" : "marucoin-mod", "intensity" : "18", "gpu-engine" : "1150", "gpu-memclock" : "1500" }, { "name" : "WestHash-Keccak", "url" : "stratum+tcp://stratum.westhash.com:4338", "user" : "BTC_addr", "pass" : "x", "thread-concurrency" : "8192", "algorithm" : "maxcoin", "intensity" : "14", "gpu-engine" : "1150", "gpu-memclock" : "1500" }, { "name" : "WestHash-X15", "url" : "stratum+tcp://stratum.westhash.com:4339", "user" : "BTC_addr", "pass" : "x", "thread-concurrency" : "8192", "algorithm" : "bitblock", "intensity" : "18", "gpu-engine" : "1150", "gpu-memclock" : "1500" }, { "name" : "WestHash-NIST5", "url" : "stratum+tcp://stratum.westhash.com:4340", "user" : "BTC_addr", "pass" : "x", "thread-concurrency" : "8192", "algorithm" : "talkcoin-mod", "intensity" : "18", "gpu-engine" : "1150", "gpu-memclock" : "1500" }, { "name" : "WestHash-NeoScrypt", "url" : "stratum+tcp://stratum.westhash.com:4341", "user" : "BTC_addr", "pass" : "x", "rawintensity" : "8192", "algorithm" : "neoscrypt", "gpu-engine" : "1150", "gpu-memclock" : "1350", "gpu-powertune" : "30", "worksize" : "64" }, { "name" : "WestHash-Lyra2RE", "url" : "stratum+tcp://stratum.westhash.com:4342", "user" : "BTC_addr", "pass" : "x", "thread-concurrency" : "8192", "algorithm" : "Lyra2RE", "intensity" : "18", "gpu-engine" : "1150", "gpu-memclock" : "1500" }, { "name" : "WestHash-X11-Last-Resort", "url" : "stratum+tcp://stratum.westhash.com:3336", "user" : "BTC_addr", "pass" : "x", "thread-concurrency" : "8192", "algorithm" : "darkcoin-mod", "intensity" : "18", "gpu-engine" : "1150", "gpu-memclock" : "1500" } ] , "xintensity" : "0", "rawintensity" : "0", "worksize" : "256", "lookup-gap" : "2", "shaders" : "0", "gpu-threads" : "2", "gpu-fan" : "30-85", "gpu-memdiff" : "0", "gpu-powertune" : "-20", "gpu-vddc" : "0.000", "temp-cutoff" : "90", "temp-overheat" : "85", "temp-target" : "72", "api-listen" : true, "api-mcast-port" : "4028", "api-network" : true, "api-port" : "4028", "api-allow" : "W:127.0.0.1", "auto-fan" : true, "auto-gpu" : false, "expiry" : "1", "failover-switch-delay" : "30", "gpu-dyninterval" : "7", "gpu-platform" : "0", "log" : "5", "no-pool-disable" : true, "no-submit-stale" : false, "queue" : "1", "scan-time" : "1", "temp-hysteresis" : "3", "shares" : "0", "failover-only" : true, "kernel-path" : "/home/user/Downloads/mining/sgminer/kernel" }
Maybe this helps, here is one of my neoscrypt settings for 280x (should work with most models), I use following settings: "algorithm" : "neoscrypt", "gpu-engine" : "1030", "gpu-memclock" : "1500", "gpu-powertune" : "20", "shaders" : "2048", "worksize" : "64", "thread-concurrency" : "16385", "intensity" : "13"
Depending on card I get 130-170 with 14.12. I am keeping GPU at 70°, increasing fan speed to 70% would give me <65°. Thank you for the reply, boki15. I currently get around 304 kh/s @ 71-72° with my neoscrypt settings. I'm using the linux driver compiled by this file "amd-driver-installer-14.20-x86.x86_64.run".
