Title: Ubuntu Mining Help - cannot get second card to mine Post by: falcoiii on July 17, 2011, 02:02:31 PM Hardware specs for my mining rig:
Power Supply 900W Motherboard MSI 870-G45 AM3 AMD 770 ATX CPU AMD Sempron 140 Memory 2GB DDR3 2 x Graphics card Radeon 6850 Running ubuntu 11.04 x64, using poclbm miner version "20110709" (also tried phoenix). There is only 1 monitor connector to the 1 monitor I have. DISPLAY=:0 Ran all of the steps in this article: http://forum.bitcoin.org/index.php?topic=7514.msg110334#msg110334 Ati config shows the 2 devices Code: aticonfig --lsa Running poclbm.py without a device shows the 2 devices: Code: ./poclbm.py -d0 http://me@yahoo.com_0:password0@pit.deepbit.net:8332 I can run a miner on d0 and d2 without any trouble, and I am getting normal hash rates for the GPU and CPU Code: ps -ef | grep pocl Every time I run poclbm.py with -d1, the program never shows it as processing hashes. CTRL-C and kill will not stop poclbm. kill -9 on the poclbm process crashes the entire computer. I tried setting DISPLAY=:0 and =:0.1 before running poclbm.py with no luck. Do I need a connectore out the back of the other graphics card? How else can I troubleshoot this? Thanks EDIT: I am running x-windows, do I need to shut it off to run 2 card mining? Title: Re: Ubuntu Mining Help - cannot get second card to mine Post by: DullJack on July 17, 2011, 04:15:54 PM I'm fairly new to linux so I can't troubleshoot it to save my life but I had a similar problem, I couldn't do anything with my 2nd and 3rd cards. I tried and tried to find a solution but finally gave up, reinstalled ubuntu and followed the guide from the second post of this thread (http://forum.bitcoin.org/index.php?topic=7514.0). I don't know what my problem was but I haven't experienced it since.
3x5830 each hashing at 297 Mhash with no overclock. Title: Re: Ubuntu Mining Help - cannot get second card to mine Post by: Rob P. on July 17, 2011, 04:16:59 PM You don't need dummy plugs under Unix.
Make sure both cards are visible as OpenCL devices, using: Code: export AMDAPPSDKROOT=/usr/local/AMD-APP-SDK-v2.4-lnx64/ Where the variables above are defined properly for where you installed AMD-APP-SDK (above assumes in /usr/local ) Mine looks like: Quote pickerin@digger02:~$ $AMDAPPSDKROOT/bin/x86_64/clinfo | grep TYPE_GPU Device Type: CL_DEVICE_TYPE_GPU Device Type: CL_DEVICE_TYPE_GPU You should get 1 line back from clinfo for each GPU that is installed. If you don't, then it's an OpenCL issue. What is the output of: Code: DISPLAY=:0 aticonfig --odgc --adapter=all Title: Re: Ubuntu Mining Help - cannot get second card to mine Post by: Rob P. on July 17, 2011, 04:18:24 PM I'm fairly new to linux so I can't troubleshoot it to save my life but I had a similar problem, I couldn't do anything with my 2nd and 3rd cards.

My 5830s are all running > 315 Mhash/sec at 1000/350 clocks. Just saying, an extra 50+ Mhash/sec is nice.

Thanks EDIT: I am running x-windows, do I need to shut it off to run 2 card mining? you did this: Quote 31. sudo aticonfig --initial -f --adapter=all right? the command, after installing OpenCL, is export DISPLAY=:0 NOT: DISPLAY=:0 you do not need a connector of any kind on the second card. you need xwindows for OpenCL mining. when you installed linux, you did a clonezilla backup of the fresh install before you changed anything, so if you screwed up you could start over quickly, right? try here (post #3) for some simpler instructions: http://forum.bitcoin.org/?topic=3356.0 i use the linux mint re-spin of debian testing on my miners - i just install it and don't do any updates except i add NTP and disable a lot of stuff in startup. try it if your 11.04 doesn't work - then follow those instructions. the fact is, ubuntu is just not as easy to mine with as a closer-to-debian version like LMDE. good luck.

Disagree, Ubuntu isn't hard at all to get running well. I've setup over a dozen rigs, all Ubuntu 11.04 Desktop. However, if you want something really simple, check out the Linuxcoin USB install elsewhere in the forums.

Make sure both cards are visible as OpenCL devices, using: Code: export AMDAPPSDKROOT=/usr/local/AMD-APP-SDK-v2.4-lnx64/ Yes, did this in ~/.bashrc and they are in the environment. Quote pickerin@digger02:~$ $AMDAPPSDKROOT/bin/x86_64/clinfo | grep TYPE_GPU Device Type: CL_DEVICE_TYPE_GPU Device Type: CL_DEVICE_TYPE_GPU I got this output back as well - two devices as expected. What is the output of: Code: DISPLAY=:0 aticonfig --odgc --adapter=all This is the output with a miner running on adapter 0: Code:
I also did do the aticonfig --initial --adapter=all Title: Re: Ubuntu Mining Help - cannot get second card to mine Post by: falcoiii on July 18, 2011, 01:46:01 PM Not sure if this is the issue - the motherboard has 2 PCI-E x16 slots, but one is x16 and one is x4 (It is a MSI 870-G45). This is what aticonfig is reporting - note the lower bus speed and channels... can I run two ATI 6850s in this configuration? I used this site for 2x5850s and replaced the 5850s with 6850s.
