Title: r9 280x Sapphire only 600kh/s on Xubuntu Linux. Post by: Lewnatic on January 05, 2014, 12:27:15 PM Hello guys, i got my mining hardware this week and started setting it up, following the guide of Cryptobadger: http://www.cryptobadger.com/2013/04/build-a-litecoin-mining-rig-linux/ (http://www.cryptobadger.com/2013/04/build-a-litecoin-mining-rig-linux/)
The only difference is, that im using a r9 280x Sapphire Dual GPU. Currently running solo. Because i want to test first before i add additional GPUs. Before switching to Xubuntu i used the GPU on my Windows 7 PC. It was running nicely with 780kh/s but on Linux only 600kh/s. =\ Quote Used Hardware: AMD SEMPRON PCU LC-Power Silent Giant LC6550GP2 Green Power 550W Scandisk 16 USB-Stick with Xubuntu v12.10 Dual-x r9 280x Sapphire GPU Asrock 970 Extreme4 1x 4GB G.Skill 1600mHz Ram Following the guide everything works nicely. Beside one error. Code: sudo aticonfig --adapter=all --odgt got me ... Code: ERROR - X needs to be running to perform AMD Overdrive(TM) commands ... everything else works properly. Seems like the cgminer settings are not the problem for that, more likely something with the drivers or maybe 280x opimized kernels for cgminer. cgminer settings are this: Code: ./cgminer --scrypt -o pool:socket -u x -p x --lookup-gap 2 --thread-concurrency 8191 -g 2 -I 13 -w 256 --memclock 1550 --gpu-engine 1150 --gpu-vddc 1.090 --shaders 2047 --auto-fan Im trying to fix this problem the whole week but nothing really helps just getting 620kh/s at maximum. Im kind of a Linux noob, so be warned. :D Cheers! Title: Re: r9 280x Sapphire only 600kh/s on Xubuntu Linux.

I'm also planning to buy the same cards, and am interested in the answer, in case I face the same issue. Title: Re: r9 280x Sapphire only 600kh/s on Xubuntu Linux. Post by: avidwriter on January 07, 2014, 06:39:58 AM try running

You need to go get the drivers from AMD's website, build the install for your version (I suggest saucy salamander) and install it. You need to uninstall the fglrx you installed with apt-get though, I don't know how. I reinstalled ;D I am also a real newbie to linux, but I managed to mangle enough of cryptobadgers guide as well as google-fu to find out how to build and install amd catalyst on Linux. Should be some good search terms for you in this post. Hope you get it working! http://i879.photobucket.com/albums/ab357/pontiacg5_2010/IMG_20131224_155039_zpsd90cd1b8.jpg 6 280's :D Title: Re: r9 280x Sapphire only 600kh/s on Xubuntu Linux. Post by: twistedtrick on January 10, 2014, 04:56:40 PM I am building my 4x 280x rig today and was planning on following Cryptobadger's guide, so thank you!

I got a solution for my problem,though. To keep this issue updated. :) I hope this will help those, who had the same issue. Thread: https://bitcointalk.org/index.php?topic=399819.msg4393272#msg4393272 Cheers! |
