In the same example of 2,1,1,1, you'd disable gpus 1, 2, and 3 in the first config file and gpu 0 in the second.Ī simpler solution is to use sgminer instead of cgminer. The solution to this problem is to run two config files, and each file will use a flag to disable the video cards from the other config file. What this means is that you can only set it once, unlike other settings, and therefore setting it in this way: "gpu-threads" : "2,1,1,1" will only use either 2 or 1 for all of the video cards. Mining with video cards that need different gpu-threadsĭue to the way cgminer was written, the gpu-threads value is a global variable. This command may not work the first time, to resolve this, delete the current file (/etc/X11/nf on Debian) and run the command again. To do so, run aticonfig -adapter=all -initialize and reboot. The error may be cause by many reasons (including failed hardware) but one of the main reasons is the addition of a new video card without reinitializing the configuration files. This is an error usually found on Linux systems. Of course, if the above doesn't work, you might have your thread concurrency set way too high! Try starting with something lower, like 8192, and trying something higher if that works. The same issue might appear in Linux if export GPU_MAX_ALLOC_PERCENT=100 wasn't added to /etc/profile ( Debian, again) You're either using the wrong version of cgminer or missing the -scrypt flag read the second paragraph of this page.ĬlCreateBuffer, decrease TC or increase LGĮrrors about clCreateBuffer and needing to decrease your TC are usually found in Windows and can be resolved by running setx GPU_MAX_ALLOC_PERCENT 100 in the Windows command prompt ( winkey+r > cmd). Running cgminer, and troubleshooting it, is made much simpler by using a config file. It is highly suggested that you create a config file for cgminer it can resolve many issues and make editing your settings very easy. Newer cards might need version 3.7.2 in order to work more effectively (or at all) with the latest SDK/drivers. For older video cards, version 3.1.1 has no scrypt or GPU mining bugs, and there are no important changes between that version and the later ones. For the newer Rx series video cards, 3.7.2 might work better. Version 3.7.2 is the last version of cgminer to support video card (GPU) or scrypt mining the -scrypt flag has been removed from later versions.įor scrypt and GPU mining, the recommended version of cgminer is 3.1.1. Windows users must either compile the source into a binary or find an unofficial download. The source code of older versions are available to compile, therefore it can still be used for Linux-based GPU mining of scrypt coins. It was the recommended software for mining cryptocoins such as Bitcoin and Litecoin, though the developer dropped support for scrypt and GPU mining, and it is no longer recommended for anything other than Bitcoin mining. Cgminer is cryptocoin mining software developed by Con Kolivas. ![]()
