GMiner 2.75: LHR update for Ethash and DevFee down to 1%

Changes v2.75 – Improved LHR performance for Ethash:

Major Gminer performance improvement for LHR GPUs on Ethash algorithm;
Improved Gminer autotuning for LHR GPUs;
DevFee: Changed developer fee to 1% on Ethash algorithm (all major Ethash miners have 1% fee).

GMiner was created by a group of Russian experts in high-performance computing and cryptography. The first version of GMiner was released on September 21, 2018 and was quite warmly received by users. Due to its unique developments and stability, in just six months the miner became a favorite on Equihash algorithms. The miner is focused on NVIDIA and AMD platforms and supports the most popular algorithms such as: Ethash, ProgPoW, KAWPOW, Equihash, CuckooCycle. GMiner maintains the leading position in mining such coins as Beam, Grin, Cortex, Bitcoin Gold. In 2020, the miner added support for Ethash, ProgPoW and KAWPOW algorithms with high performance relative to competitors. The development team never rests on its laurels and achieves maximum algorithm performance with minimal power consumption, these are the qualities that distinguish GMiner from its competitors and win the hearts of users.

Features of the GMiner cryptocurrency miner:

The commission is charged constantly, and not in intervals (as with most miners), which has a positive effect on the user’s profitability on PPLNS pools
Checking the generated DAG, Warning on very high GPU overclocking for Ethash algorithms , Etcash, KAWPOW and ProgPoW, helps to overclock the GPU without errors
checking the total resources on the processor, warning when the GPU is very high overclocked for Ethash, Etcash, KAWPOW and ProgPoW algorithms, helps to overclock the GPU without errors
DAG caching when there is enough GPU memory, DAG files are not recalculated when switching to another algorithm when mining Ethash + Zilliqa or Nicehash, which positively affects the user’s profitability
auto-selection of optimal cores for each device on Ethash, Etcash, KAWPOW
ability to manually select a kernel on each device for Ethash, Etcash
Temperature control and GPU shutdown quarrel in case of overheating
watchdog — process-observer of the state of the main systems of the miner, which will restart the miner in case of failure or freeze
mechanism for restoring a lost connection to the pool
support for failover pools, the miner uses failover pools until the connection to the main pool is restored
secure connections support
SOCKS5 proxy support
informative and readable tabular statistics displayed on the console
displaying detailed information for each device (temperature, power consumption, cooler load, memory frequency, processor frequency, energy efficiency)
parallel output of information to the console and in file to disk
built-in statistics server – remote monitoring of the miner in the browser
memory settings for Nvidia GPUs with GDDR5X and GDDR5 memory
core frequency, memory frequency, core voltage, memory voltage, fan speed, power limit, overclocking for Windows
secure DAG creation for Nvidia GPUs
automatically adjust fan speed for a given temperature

GMiner: How to Start Mining

Ethash

To start Ethash, type at the command prompt:

miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1

—algo — mining algorithm, in this case ethash
—server — pool address and port, in this case eth.2miners.com pool, port 2020
–user – Ethash wallet and worker name, in this case wallet – 0x5218597d48333d4a70cce91e810007b37e2937b5, worker – worker1

Ethash and Etchash

For Ethash and Etchash algorithms there are 2 stratum protocol options (proxy and stratum), to explicitly specify the protocol, use the parameter “-proto”, for example, to use the Nicehash pool, type in the command line:

miner --algo ethash --server daggerhashimoto.usa.nicehash.com:3353 --user 3LsTTSsSy17xuoShcMHuRgGBxKn1AHgeVN --proto stratum

If you have a mixed installation, you can only run the miner on CUDA devices:

miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --opencl 0

or only on OpenCL devices:

miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --cuda 0

or on devices of your choice, such as GPU0, GPU2 and GPU4:

miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --devices 0 2 4

a list of available GPUs can be seen by calling the following command:

miner --list_devices

To set temperature limits for GPU0, GPU2 and GPU4, when reached, mining on this device will be suspended until it cools down:

miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --devices 0 2 4 --templimit 80 70 65

where 80 is the temperature limit for GPU0, 70 is the temperature limit for GPU2, 65 is the temperature limit for GPU4

To save the miner logs to a file for later analysis:

miner --algo ethash --server eth.2miners.com:2020 --user 0x5218597d48333d4a70cce91e810007b37e2937b5.worker1 --logfile log.txt

where “log.txt” is the path to the log file of the miner
