Title: R9 290x Post by: kpt8 on April 06, 2014, 07:01:37 PM Hi, I have a R9 290x. And I would mine on wemineall.com. I use sgminer-4.1.0, Win 7 32-bit. But miner rate is very low. (<500 KH / s)
How to configure miner? I used following configuration: Quote { "pools" : [ { "url" : "stratum+tcp://multi1.wemineall.com:5555", "user" : "kpt8.1", "pass" : "x" } ] , "intensity" : "13", "xintensity" : "0", "rawintensity" : "0", "worksize" : "256", "kernel" : "scrypt", "lookup-gap" : "2", "thread-concurrency" : "8192", "shaders" : "0", "gpu-threads" : "1", "gpu-engine" : "0", "gpu-fan" : "auto", "gpu-memclock" : "0", "gpu-memdiff" : "0", "gpu-powertune" : "0", "gpu-vddc" : "0.000", "temp-cutoff" : "95", "temp-overheat" : "89", "temp-target" : "85", "api-mcast-port" : "4028", "api-port" : "4028", "expiry" : "1", "failover-switch-delay" : "60", "gpu-dyninterval" : "7", "gpu-platform" : "0", "log" : "5", "no-pool-disable" : true, "queue" : "1", "scan-time" : "1", "tcp-keepalive" : "30", "temp-hysteresis" : "3", "shares" : "0", "kernel-path" : "/usr/local/bin" } Title: Re: R9 290x Post by: henrik_z on April 07, 2014, 03:19:04 AM Try these settings first:
intensity: 20 thread-concurrency: 32765 gpu-engine: 920 gpu-memclock: 1500 This should net you 882kh/s. Let that settle for a while and see how you go. After a while of that, try changing gpu-engine to 1025. If you've got Hynix RAM you'll get close to 1MH.. Elpida OTOH will slow down (if that happens, stick with 920) Title: Re: R9 290x Post by: SpeedDemon13 on April 07, 2014, 03:36:19 AM Your TC setting is low for a 290/290x card. Plus some times the card likes gpu thread of 2. In your case, it just looks like a low TC.
Title: Re: R9 290x Post by: kpt8 on April 07, 2014, 08:36:37 PM Is it a reference card? If so, I might be able to get you about 1MH/s on it. I've reached 1080kh/s on my Sapphire 290X (reference) with Hynix memory. Yep. Its a reference. Try these settings first: intensity: 20 thread-concurrency: 32765 gpu-engine: 920 gpu-memclock: 1500 This should net you 882kh/s. Let that settle for a while and see how you go.

Elpida OTOH will slow down (if that happens, stick with 920) I try your settings, but have not results.

I your case, it just looks like a low TC. I use your recommendation. Miner rate up. (+15%) Title: Re: R9 290x Post by: SpeedDemon13 on April 07, 2014, 08:52:29 PM Is it a reference card?

(+15%) You need these in your config or bat file: setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 Title: Re: R9 290x Post by: henrik_z on April 07, 2014, 10:13:43 PM You need these in your config or bat file: setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_USE_SYNC_OBJECTS 1 +1 yes, this! In my experience tc 32765 and g 1 is optimum for 290Xs, but it won't work without the above.

Title: Re: R9 290x Post by: envy2010 on April 09, 2014, 06:25:51 PM The problem is probably your OS. I have never been able to effectively use a card when I have less usable system memory than the amount of video memory on the card (per GPU). For example, to use a 280X with 3GB of VRAM, I need 4GB of system RAM and a 64-bit OS. The problem does not scale with more cards, so I can run 3x 2GB cards on a 32-bit OS, but have never been able to run even a single 3GB card. I have not been able to figure out why (the miner only actually uses about 50MB of system RAM), but that's just the way it works.
The "thread-concurrency" setting is limited by video and system memory, among other things. A 2GB card likes a TC of 8000 to 16000, a 3GB card 21000 to 24000, and a 4gb card 30000 or higher, but with a 32 bit OS you probably won't be able to run a TC over 16000.

Are you using MSI Afterburner, Sapphire Trixx or AMD Overdrive to control your clock speeds? When I set the parameter TC = 32765...
