lolMiner 1.12: AMD Miner for Ethash / BEAM / GRIN / Ae / Tube / Equihash & more

[Joseph12]

lolMiner 1.12
This is the announcement thread for lolMiner 1.12  a multi algorithm Ethash / Equihash / Beam & Grin miner with focus on AMD GPUs (OpenCL based).
Note it will run on most Nvidia GPUs, too but the speed and stability may vary.

Driver Requirement:
Windows: Adrenaline 19.1 & newer (pre Navi) / 19.10.02 & newer (Navi), Linux: 18.10 & newer (RX 390, Fury, 470-580),  18.50 & newer (Vega, VII), 19.30 & newer (Navi)
Note: New Beam Hash III may support Blockchain drivers (untested)

CLick to download lolMiner 1.12

Changelog

Version 1.12

• Added support for ETCHash (Ethereum Classic dag size reduction planned for end November). Use --algo ETCHASH to activate it. (See note below).
• Reworked Ethash codes for late epochs on Windows. See  4G_Windows_Readme.txt for configuring it.
• Slightly improved Ethash efficiency for GCN 3 (R9 Fury, 470 - 590) & Navi cards
• Added experimental support for Ethash on Nvidia GPUs (See note below)
• Added new parameter: --4g-alloc-size to define the memory allowed for Ethash on 4G cards. Maxing out will give more epochs of mining & better Zombie mode performance, lower values may improve compatibility. Suggested values: Linux: 4076 Windows 4008 - 4024
• Added new parameter: --worker to set the worker in ETHPROXY stratum mode (improves pool compatibility)
• Overall new Ethash host size back end - hopefully improving stability of mining
• Fixed bug: Zombie mode generates defect shares in Windows
• Fixed bug: Logs were not written when "LOG" : 1 was set in json style config file

Note about ETC Mining
Ethereum Classic is going to reduce their DAG file size by end of November. To make the miner compatible either use --algo ETCHASH, --coin ETC or --algo ETHASH --enable-ecip1099. Also it can be activated by the pool when mining Ethash, if the pools sends "algo" : "etchash" with a new work message (this is planned by some pools, e.g. 2Miners).

Note that up to epoch 389 ETCHash and Ethash is identical. If you mine ETC on a 4G card it will have entered Zombie Mode on epoch 382 (in Linux) and will stay in there until epoch 389. When epoch 390 starts it will jump back to normal speed.

If you want to mine the ETC mordor testnet, add special parameter "--ecip1099-activation 82" to configure the miner that it switches on testnet epoch 82 (default is mainnet epoch 390)

Note about Nvidia Mining
lolMiner will use OpenCL also for Nvidia mining. That said if your cards are not shown on miner startup you may need to install cuda-toolkit which includes the OpenCl drivers. Note that Nvidia OpenCl execution only knows busy waits for the GPUs to check if they have completed work. Thus using it give high load one core of your CPUs cores independently of the CPU speed. This is considered normal!
