Note hashrate info is not available in geth when GPU mining. Check your hashrate with ethminer, miner.hashrate will always report 0. CPU Mining with Geth ethereum opencl error for single gpu. When you start up your ethereum node with geth it is not mining by default. To start it in mining mode, you use the --mine command-line flag.For NVidia install the 347.52 driver and the latest OpenCL CUDA package, which is CUDA 8.0 at the time of writing. For AMD, install Radeon Software Crimson Edition 15.12 and the OpenCL SDK Package. Depending on your GPU, this might not be the correct driver. So if you're having issues, check the Ethereum Forum for advice. 3. Install Additional.Only 5 GPUs working? 6th GPU fails to hash? failing GPU keeps changing as the miner restarts? This is how you fix the failling 6th GPU when it says GPU EAMD Radeon VII is the most powerful GPU miner for Ethereum today. The average hashrate of the card is about 78 MH/s and can achieve 90 MH/s without any tweaking. Such results became possible because of the improved memory bandwidth of the new card – 1TB/s and 16GB of HBM2.single GPU index: e.g. 5:1000 sets 1000 for the 5th GPU range of GPU indexes: e.g 2-5:1200 sets 1200 for the GPUs 2,3,4, and 5 asterisk, which sets the value for all GPUs label amd or nvidia: e.g. amd:1090 sets the value to 1090 for all AMD cardsGPU_FORCE_64BIT_PTR 0 GPU_MAX_HEAP_SIZE 100 GPU_USE_SYNC_OBJECTS 1 GPU_MAX_ALLOC_PERCENT 100 GPU_SINGLE_ALLOC_PERCENT 100 EthDcrMiner64.exe -epool eth-asia1.nanopool:9999 -ewal <my address link> -epsw x -mode 1 -ftime 10You can get clinfo for your linux and then run it. It provides a list of every platform and devices found. If you can't get your device listed by clinfo, you won't have it listed by your program. It looks like you have a Nvidia Optimus computer, and it is very bad because Nvidia does not provide official support for Optimus on Linux.PhoenixMiner 5.6d - AMD+NVIDIA GPU Miner. Effective Ethereum mining speed is higher by 3-5% because of a completely different miner code - much less invalid and outdated shares, higher GPU load, optimized OpenCL code, optimized assembler kernels. Supports both AMD and nVidia cards (including in mixed mining rigs).I am trying to mine Ethereum using geth and ethminer using a single AMD Radeon HD 7850 with 2 GB of memory on Ubuntu 16.04. I installed the latest recommended driver, ran geth --maxpeers 0 (to avoid syncing with the blockchain) and then tried to benchmark my setup using ethminer -G -M. I get a few possible OpenCL error messages when trial 1 is beginning, then that phase ends with a hashrate of 0, same for trial 2, 3, 4 and 5. Ethereum opencl error for single gpu.

Recently the epoch on the ETH blockchain reached values that make some 4GB GPUs unable to mine this coin. The errors you might see in your mining clients are and similar - all related to “DAG.You can launch an OpenCL kernel that uses many threads (work items). The GPU will process them at whatever rate it is able. The instantaneous capacity of the GPU is specified (e.g. 1536 work items can be resident per Fermi SM) but this does not mean you should think about writing programs that use 1536 work items for the global size (or the local size, for that matter).I am also experiencing this issue with all my MSI R9 270 cards; They have 2 GB of memory. ethminer --list-devices results in the following output: [OPENCL]: Listing OpenCL devices ethereum opencl error for single gpu.Open up another Command Prompt (leave the first one running!), change directory by typing cd /Program Files/Ethereum (++)/release. Now make sure geth has finished syncing the blockchain. If it is not syncing any longer, you can start the mining process by typing ethminer -G at the command prompt.XMR: 6 pools are specified Main Monero pool is xmr-eu1.nanopool:14433 At least 16 GB of Virtual Memory is required for multi-GPU systems Make sure you defined GPU_MAX_ALLOC_PERCENT 100 Be careful with overclocking, use default clocks for first tests Press "s" for current statistics, "0"."9" to turn on/off cards, "r" to reload pools OpenCL.Every next Ethereum epoch requires a bit more GPU memory, and the miner can crash during reallocating GPU buffer for new DAG.
