![]() ![]() An example of using the setting looks like this: "-gpu-map 2:1,1:2", which doesn't mean much without context, so I highly recommend reading that link. Here is the link: /luke-jr/bfgminer/blob/bfgminer/README.GPU and the information is about 2/3 down starting with the header, "GPU DEVICE ISSUES and use of -gpu-map". I also get the same error for Number of OpenCL and ADL devices not matching but my devices still mine to their full potential. When I try to start cgminer on windows it throws the following error: Command: cgminer -scrypt -o -u usernmae -p mypass -thread-concurrency 8192 -I 10 -g 1 -w 256 :687: error: no matching overload found for arguments of type 'unsigned int attribute ( (extvectortype ( 4))), unsigned int' B i+4. ![]() I think that it would be better for me to give you a link to read about the setting, as it would provide more information and examples. Could you give an example of teh -gpu-map setting?Īnother option to try the -gpu-map setting also to make sure the devices are seen properly, as there are sometimes issues with 2 video cards and one monitor and other weird scenarios. This is almost working except cgminer is now telling me that Number of OpenCL and ADL devices did not match. Then once they are mining it is good to start to fine tune.Īlso, I seem to remember that the SDK version that is suggested to use with R9s is not a version that works to mine with the Radeon 7000 series. If those TC settings don't work, try 8000,8192 perhaps and lowering intensity on both to 18, or even 17 while you get them started. I also told it to start GPU 0 at intensity 18, as the Radeon 7000 series seems to run better at 18 than 19 in my experience. ![]() You said that your 7790 is GPU 0, that's why I put the TC 8000,15232 (TC for 7790 first, then TC for R9). I am unsure how to run more instances of CGMiner for multiple cards that wont cause conflicts and crash video cards. CGMiner includes overclocking, monitoring, fan speed control and remote interface. One of the things that make it extremely popular is the fact that it’s based on the original code Cpu Miner, which you can discover in BitcoinWiki. You must specify values for both cards or it will try to use the same thread concurrency on both cards, which most likely was causing the 7790 to fail. CGminer is an open-source GPU miner written in C available for several platforms like Windows, Linux and OS X. cgminer -scrypt -o stratum+tcp://my.pool.ip:xxxx -u myusername -p mypassword -d 0,1 -I 18,19 -g 1 -w 256 -thread-concurrency 8000,15232 You need to tell CGMiner you have two GPUs and set the thread concurrency for them. Any account older than 3 days can add a pool here, feel free to modify this.Have you tried the command -d 0,1, then setting your Thread Concurrency and Looup-gap and worksize for each device accordingly. /r/CUDAManager: Provides additional features to miners, but to also makes it easier for a new user to start mining and get involved with the cryptocurrency world.GUIminer: A tool combining all types of miners, coming with a graphical interface.
