Title: Optimal .conf file for HD5850 (CGminer/SGminer) Post by: ToScA- on February 05, 2014, 04:45:23 PM Hi!
I'm about to use a dual-GPU mining rig (a Sapphire R9 290 Tri-X OC and an Asus Radeon 5850). I'm wondering what .conf parameters others are using for their 5850s in CGminer or SGminer? Not a .bat-file by the way, but a .conf-file. I'm not very good at converting my .bat-settings to .conf as it never works out well; always some parameter missing :P Any help is MUCH appreciated! Thanks!! Title: Re: Optimal .conf file for HD5850 (CGminer/SGminer) Post by: ToScA- on February 05, 2014, 07:19:27 PM Slight bump.
I tried these settings for the 5850. It worked well initially, but after a few minutes, SGMiner showed status "SICK", followed a few minutes later på "DEAD" What am I doing wrong? :( { "pools" : [ { "name" : "netcodepool.org", "url" : "stratum+tcp://netcodepool.org:3333", "user" : "username.worker", "pass" : "x" } ], "scrypt" : true, "auto-fan" : true, "gpu-threads" : "1", "gpu-engine" : "0-850", "gpu-fan" : "0-100", "gpu-memclock" : "0-1025", "gpu-memdiff" : "0", "gpu-powertune" : "0", "gpu-vddc" : "0.000", "intensity" : "19", "temp-target" : "70", "temp-overheat" : "85", "temp-cutoff" : "95", "vectors" : "1", "worksize" : "256", "lookup-gap" : "0", "shaders" : "0", "thread-concurrency" : "5824" } Title: Re: Optimal .conf file for HD5850 (CGminer/SGminer) Post by: mindsplit on February 05, 2014, 08:27:35 PM Did you check the temperature? Try a lower intensity setting.
Also I think you can remove these lines if you use sgminer: "gpu-memdiff" : "0", "gpu-powertune" : "0", "gpu-vddc" : "0.000", "vectors" : "1", "shaders" : "0", "scrypt" : true, Title: Re: Optimal .conf file for HD5850 (CGminer/SGminer) Post by: ToScA- on February 05, 2014, 09:25:42 PM Did you check the temperature?

I haven't made much progress, I always get some kind of display driver error now on the 5850. The R9 290 runs fine though. Current config for both GPUs: (first being the 5850, second is the R9 290) "api-allow" : "W:127.0.0.1", "api-listen" : true, "api-port" : "4028", "expiry" : "120", "failover-only" : true, "kernel-path" : "/usr/local/bin", "log" : "5", "queue" : "1", "scan-time" : "60", "auto-fan" : true, "gpu-threads" : "1", "gpu-engine" : "725,1000", "gpu-fan" : "0-100,50-90", "gpu-memclock" : "1000,1350", "gpu-reorder" : true, "intensity" : "13,20", "temp-target" : "70", "temp-overheat" : "95", "temp-cutoff" : "99", "temp-hysteresis" : "3", "worksize" : "256", "lookup-gap" : "0,2", "thread-concurrency" : "5824,32765" } These were my .bat-file srttings for 5850 before I bought the R9 290: -I 13 -g 1 -w 256 --thread-concurrency 5824 I don't get what I'm doing wrong. :( There's obviously more parameters in the .conf-file, but I don't know what to change. Title: Re: Optimal .conf file for HD5850 (CGminer/SGminer) Post by: drdanger_pi on February 09, 2014, 04:51:28 PM I'm getting 340 Kh/s ;D with sgminer using the following script:
"intensity" : "21", "worksize" : "256", "kernel" : "ckolivas", "lookup-gap" : "2", "thread-concurrency" : "5864", "gpu-engine" : "0-800", "gpu-fan" : "0-85", "gpu-memclock" : "1150", "gpu-memdiff" : "0", "gpu-powertune" : "0", "gpu-vddc" : "0.000", "gpu-dyninterval" : "7", "gpu-platform" : "0", I would like to try the new kernels that comes with sgminer, but it looks like you need to retune the thread-concurrency |
