Title: CGminer - No devices found Post by: Serellyn on January 02, 2014, 07:55:32 PM Hey guys,
So I've got this new mining rig, 2 x r9 280x cards. These are meant to mine some alt cryptocurrencies. Anyway, fresh Windows 7 install. Installed the latest catalyst control center (13.12). But when starting CGminer it gives me the following error: clDevicesnum returned error: no gpus usable Does anyone know why this is? Using CGminer 3.7.2 with the following config file Quote { "pools" : [ { "url" : "http://doge.poolerino.com:3333", "user" : "nikitanl.Alexis", "pass" : "x" } ] , "intensity" : "13,13", "vectors" : "1,1", "worksize" : "256,256", "kernel" : "scrypt,scrypt", "lookup-gap" : "0,0", "thread-concurrency" : "8191,8191", "shaders" : "2048,2048", "gpu-engine" : "1125-1125,1125-1125", "gpu-fan" : "30-70,30-70", "auto-fan" : true, "gpu-memclock" : "1750,1750", "gpu-memdiff" : "0,0", "gpu-powertune" : "-20,-20", "gpu-vddc" : "0.000", "temp-overheat" : "85", "temp-target" : "72", "api-port" : "4028", "expiry" : "60", "gpu-dyninterval" : "7", "gpu-platform" : "1", "gpu-threads" : "2", "hotplug" : "5", "log" : "5", "no-pool-disable" : true, "queue" : "1", "scan-time" : "60", "scrypt" : true, "temp-hysteresis" : "3", "shares" : "0", "load-balance" : true, "kernel-path" : "/usr/local/bin" } I have tried other versions of CGminer too, that does not seem to be the case.

I had to fool around with the catalyst control center versions and cgminer versions as well. Do you have the SDK App? I think it might come with that catalyst control center version though, so I'm not sure. If there was something I was going to fool around with it'd be the AMD drivers.

I was actually just posting a reply, but noticed you replied to. I actually managed to solve the problem by altering the config file, and disable/enable one of the cards. I'm now just using single values in the config file. Hope this thread helps future miners a bit :) Check your config file boys! |
