- Driver version: >= 377.
- BTM Mining:
- Edit start_btm.bat, modify mining pool url after -o and username or wallet address after -u.

- Edit start_eth.bat, modify mining pool url after -o and username or wallet address after -u.
- For users using 1080, 1080ti, 1060-5X cards, which equiped with GDDR5X memory, remember to start OhGodAnETHlargementPill-r2.exe patch before mining and keep it running background.
- BTM+ETH Dual Mining:
- Edit start_btm_eth.bat
- Set mining pool for BTM after option -o, set username for BTM pool after option -u
- Set mining pool for ETH after option -do, set username for ETH pool after option -du
- There is an option -di (secondary-intensity) stands for the relative intensity of mining ETH. Tuning this option to get best performance on different cards.
- Grin Mining:
- Edit start_grin.bat
- Set mining pool for Grin after option -o, set username for Grin pool after option -u

- BTM with SSL: stratum+ssl://btm.f2pool.com:9443
- ETH: ethproxy+tcp://eth.f2pool.com:8008
- ETH with NiceHash: ethnh+tcp://daggerhashimoto.eu.nicehash.com:3353
- -u, --user <user> User used in Mining pool, wallet address or username.
- Format: [username|wallet].workername:password
- Example: bm1xxxxxx.worker myusername.worker:password
- -o1, --url1 <url> url for backup mining pool 1.
- -u1, --user1 <user> username for backup mining pool 1.
- -o2, --url2 <url> url for backup mining pool 2.
- -u2, --user2 <user> username for backup mining pool 2.
- -di, --secondary-intensity <intensity> The relative intensity for ETH when dual mining. recommend: 8 - 24, default to 16.
- -do, --secondary-url <url> ETH mining pool when dual mining.
- -du, --secondary-user <user> ETH username when dual mining.
- -do1, --secondary-url1 <url> Backup 1 ETH mining pool when dual mining.
- -du1, --secondary-user1 <user> Backup 1 ETH username when dual mining.
- -do2, --secondary-url2 <url> Backup 2 ETH mining pool when dual mining.
- -du2, --secondary-user2 <user> Backup 2 ETH username when dual mining.
- -d, --devices <devices> Specify GPU list to use. Format: "-d 0,1,2,3" to use first 4 GPU.
- --strict-ssl Check validity of certificate when use SSL connection.
- --log Generate log file named log_<timestamp>.txt.
- --long-format Use 'yyyy-MM-dd HH:mm:ss,zzz' for log time format.

GPU Tuning

- BTM + ETH:
- Suitable secondary intensity depends on the ratio of core performance / memory bandwidth
- GPU with relative low memory bandwidth, eg. 1070ti, could tune down the di. Otherwise tune up.
- The ratio changes with different core, tdp, memory settings when overclock GPU.
- BTM:
- Bytom mining performance depend heavily on GPU core, instead of GPU memory.
- Miner can gain beffer hashrate if tuning down GPU memory frequency.
- For example, using MSI Afterburner to turn down GPU memory to -500.
