Title: 1st Try at GPU mining ETH, I think I owe ! Post by: HashZilla on September 12, 2016, 12:27:02 AM Hello; I wonder if someone could help understand my results. Background( Windows 7, Sapphire Nitro RX 470 8GB, OpenCL installed, eth installed.) My first attempt at mining does not look successful, as eth doesn't seem to recognize the GPU. I used the following command.... c:\Program Files\cpp-ethereum>eth -v 1 -a (my address) --client-name HashZilla -x 50 -m on -G I got the following result.... cpp-ethereum, a C++ Ethereum client No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G argument So I set the OpenCL parameters and tried again.... c:\Program Files\cpp-ethereum>setx GPU_FORCE_64BIT_PTR 0 SUCCESS: Specified value was saved. c:\Program Files\cpp-ethereum>setx GPU_MAX_HEAP_SIZE 100 SUCCESS: Specified value was saved. c:\Program Files\cpp-ethereum>setx GPU_USE_SYNC_OBJECTS 1 SUCCESS: Specified value was saved. c:\Program Files\cpp-ethereum>eth -v 1 -a 0x7643715CF78eB75ee857f7203B3365741205 6655 --client-name HashZilla -x 50 -m on -G cpp-ethereum, a C++ Ethereum client No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G ar gument I checked the device list.... c:\Program Files\cpp-ethereum>ethminer --list-devices Listing OpenCL devices. FORMAT: [deviceID] deviceName
CL_DEVICE_GLOBAL_MEM_SIZE: 8589934592 CL_DEVICE_MAX_MEM_ALLOC_SIZE: 4244635648 CL_DEVICE_MAX_WORK_GROUP_SIZE: 256 I also specified the GPU device with the following command.... c:\Program Files\cpp-ethereum>eth -v 1 -a 0x7643715CF78eB75ee857f7203B3365741205 6655 --client-name HashZilla -x 50 -m on -G --opencl-device 0 cpp-ethereum, a C++ Ethereum client No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G ar gument Is this the correct device information for the RX 470 ? Thanks Zilla Title: Re: 1st Try at GPU mining ETH, I think I owe !

Load Amd 16.9.1 drivers Title: Re: 1st Try at GPU mining ETH, I think I owe ! Post by: HashZilla on September 12, 2016, 01:06:40 AM I loaded the 16.9.1 hotfix which provides identical results with the eth package. Are you suggesting my efforts should have worked, and probably would with Claymore? thanks Title: Re: 1st Try at GPU mining ETH, I think I owe ! Post by: HashZilla on September 12, 2016, 02:20:58 AM 16.9.1 + Claymore works! thanks |
