PhoenixMiner 5.0b: fastest Ethereum/Ethash miner with lowest devfee (Win/Linux)

[oplono2]

IMPORTANT! All owners of AMD cards with 4 GB RAM must upgrade to PhoenixMiner 5.0b or later version to continue mining after DAG epoch 350 (i.e. about the start of June 2020 for ETC, and the middle of July 2020 for ETH).

Changes in version 5.0b (since 4.9c):

• Added support for mining with 4 GB AMD cards beyond the DAG epoch 350. Depending on the OS and driver versions, you will be able to use 4 GB AMD cards until epoch 372-373 under Windows, and 380 under Linux.
• Added new -dagrestart command-line option to work around the problems with DAG allocation on 4 GB AMD cards under some driver versions. See Readme.txt for more information.
• Added support for latest AMD drivers 20.4.2 under Windows and 20.10-1048554 under Linux
• Many other small improvements and fixes

PhoenixMiner is fast (arguably the fastest) Ethash (ETH, ETC, Muiscoin, EXP, UBQ, etc.) miner that supports
both AMD and Nvidia cards (including in mixed mining rigs). It runs under Windows x64 and Linux x64
and has a developer fee of 0.65% (the lowest in the industry). This means that every 90
minutes the miner will mine for us, its developers, for 35 seconds.

PhoenixMiner also supports Ubqhash for mining UBQ, ProgPOW for mining BCI, and dual mining
Ethash/Ubqhash with Blake2s.

The speed is generally faster than Claymore's Ethereum miner in eth only mode
(we have measured about 0.4-1.3% speed improvement but your results may be slightly lower or
higher depending on the GPUs). To achieve highest possible speed on AMD cards it may be needed
to manually adjust the GPU tune factor (a number from 8 to about 400, which can be changed
interactively with the + and - keys while the miner is running).

If you have used Claymore's Dual Ethereum miner, you can switch to PhoenixMiner with
minimal hassle as we support most of Claymore's command-line options and confirguration
files.

Please note that PhoenixMiner is extensively tested on many mining rigs but there still may be some bugs.
Additionally, we are actively working on bringing many new features in the future releases.
If you encounter any problems or have feature requests, please post them here (in this thread).
We will do our best to answer in timely fashion.

* Supports the ProgPOW algorithm for mining BCI.
* More features coming soon!

PhoenixMiner requires Windows x64 (Windows 7, Windows 10, etc.), or Linux x64 (tested on Ubuntu LTS
and Debian stable).

PhoenixMiner also supports dual mining (simultaneous mining of ethash/ubqhash and other cryptocoin algorithm).
Currently we support only Blake2s as secondary algorithm for dual mining. Note that when using dual mining,
there is no devfee on the secondary coin but the devfee on the main coin is increased to 0.9%. In other words,
if you are using the dual mining feature PhoenixMiner will mine for us for 35 seconds every 65 minutes.

Solo mining is supported since version 2.7c.

While the miner is running, you can use some interactive commands. Press the key 'h' while the
miner's console window has the keyboard focus to see the list of the available commands. The
interactive commands are also listed at the end of the following section.

3. Command-line arguments

Note that PhoenixMiner supports most of the command-line options of Claymore's dual Ethereum miner
so you can use the same command line options as the ones you would have used with Claymore's miner.

Pool options:
  -pool <host:port> Ethash pool address (prepend the host name with ssl:// for SSL pool, or http:// for solo mining)
  -wal <wallet> Ethash wallet (some pools require appending of user name and/or worker)

  -worker <name> Ethash worker name (most pools accept it as part of wallet)
  -proto <n> Selects the kind of stratum protocol for the ethash pool:
     1: miner-proxy stratum spec (e.g. coinotron)

  -dpass <password> Dual mining pool password (most pools don't require it, use 'x' as password if unsure)
  -dworker <name> Dual mining worker name
  -dcoin blake2s Currently only the Blake2s algorithm is supported for dual mining. If you want to put
        all dual mining pools in dpools.txt, you need to set -dcoin blake2s in the command-line or in config.txt
   to force the miner to load the dual mining pools from dpools.txt
  -dstales <n> Submit stales to the dual mining pool: 1 - yes (default), 0 - no
General pool options:
  -fret <n> Switch to next pool afer N failed connection attempts (default: 3)
  -ftimeout <n> Reconnect if no new ethash job is receved for n seconds (default: 600)
  -ptimeout <n> Switch back to primary pool after n minutes. This setting is 30 minutes by default;
     set to 0 to disable automatic switch back to primary pool.
  -retrydelay <n> Seconds to wait before reconnecting (default: 20)
  -gwtime <n> Recheck period for Solo/GetWork mining (default: 200 ms)
  -rate <n> Report hashrate to the pool: 1 - yes, 0 - no (1 is the default), 2 - (for solo mining only)
     use alternative name of the report method "eth_submitHashRate" instead of "eth_submitHashrate"
Benchmark mode:
  -bench [<n>],-benchmark [<n>] Benchmark mode, optionally specify DAG epoch. Use this to test your rig.
     If you specify only the -bench option, you will benchmark the ethash algorithm. If you want to bench
     the dual mining, use the options -bench <n> -dcoin blake2s. If you want to benchmark the ProgPOW BCI
     algorithm, use the options -bench <n> -coin bci
Remote control options:
  -cdm <n> Selects the level of support of the CDM remote monitoring:
     0: disabled
     1: read-only - this is the default
     2: full (only use on secure connections)
  -cdmport <port> Set the CDM remote monitoring port (default is 3333). You can also specify
     <ip_addr:port> if you have a secure VPN connection and want to bind the CDM port to it
  -cdmpass <pass> Set the CDM remote monitoring password
  -cdmrs Reload the settings if config.txt is edited/uploaded remotely. Note that most options require restart in order to change.
      Currently the follwing options can be changed without restarting: -mi, -gt, -sci, -clf, -nvf, and all hardware control parameters
      (-tt, -fanmin, -fanmax, -powlim, -tmax, -cclock, -cvddc, -mclock, -mvddc).
Mining options:
  -amd  Use only AMD cards
  -acm  Turn on AMD compute mode on the supported GPUs. This is equivalent of pressing 'y' in the miner console.
  -nvidia  Use only Nvidia cards
  -gpus <123 ..n> Use only the specified GPUs (if more than 10, separate the indexes with comma)
  -mi <n> Set the mining intensity (0 to 14; 12 is the default for the new kernels). You may specify this option per-GPU.
  -gt <n> Set the GPU tuning parameter (6 to 400). The default is 15. You can change the
          tuning parameter interactively with the '+' and '-' keys in the miner's console window.
          If you don't specify -gt or you specify value 0, the miner will start auto-tuning to determine the best GT value for each GPU
          Note that when the GPU is dual-mining, it ignores the -gt values, and uses -sci instead.
  -sci <n> Set the dual mining intensity (1 to 1000). The default is 30. As you increase the value of -sci,
           the secondary coin hashrate will increase but the price will be higher power consumption and/or
           lower ethash hashrate.
           You can change the this parameter interactively with the '+' and '-' keys in the miner
           console window. You may specify this option per-GPU. If you set -sci to 0,
      the miner will use auto-tuning to determine the best value, while trying to maximize the
      ethash hashrate regardless of the secondary coin hashrate.
  -clKernel <n> Type of OpenCL kernel: 0 - generic, 1 - optimized, 2 - alternative, 3 - turbo (1 is the default)
  -clGreen <n> Use the power-efficient ("green") kernels (0: no, 1: yes; default: 0).
                 You may specify this option per-GPU. Note that you have to run auto-tune again as the
                 optimal GT values are completely different for the green kernels
  -clNew <n> Use the new AMD kernels (0: no, 1: yes; default: 1)
  -clf <n> AMD kernel sync (0: never, 1: periodic; 2: always; default: 1)
  -nvKernel <n> Type of Nvidia kernel: 0 auto (default), 1 old (v1), 2 newer (v2), 3 latest (v3).
                Note that v3 kernels are only supported on GTX10x0 GPUs. Also note that dual mining is
                supported only by v2 kernels. You may specify this option per-GPU.
  -nvdo <n> Enable Nvidia driver-specific optimizations (0 - no, the default; 1 - yes). Try -nvdo 1 if your
            are unstable. You may specify this option per-GPU.
  -nvNew <n> Use new Nvidia kernels if supported (0: no, 1: yes; default: 1)
  -nvf <n> Nvidia kernel sync (0: never, 1: periodic; 2: always; 3: forced; default: 1). You may specify this option per-GPU.
  -mode <n> Mining mode (0: dual mining if dual pool(s) are specified; 1: ethash only even if dual pools are specified).
            You may specify this option per-GPU.
  -list List the detected GPUs devices and exit
  -gbase <n> Set the index of the first GPU (0 or 1, default: 1)
  -minRigSpeed <n> Restart the miner if avg 5 min speed is below <n> MH/s
  -eres <n> Allocate DAG buffers big enough for n epochs ahead (default: 2) to
      avoid allocating new buffers on each DAG epoch switch, which should improve DAG switch stability
  -dagrestart <n> Restart the miner when allocating buffer for a new DAG epoch. The
      possible values are: 0 - never, 1 - always, 2 - auto (the miner decides depending on the driver version).
      This is relevant for 4 GB AMD cards, which may have problems with new DAG epochs after epoch 350.
  -lidag <n> Slow down DAG generation to avoid crashes when swiching DAG epochs
      (0-3, default: 0 - fastest, 3 - slowest).
  -gser <n> Serializing DAG creation on multiple GPUs (0 - no serializing, all GPUs generate the DAG simultaneously, this is the default;
      1 - partial overlap of DAG generation on each GPU; 2 - no overalp (each GPU waits until the previous one has finished generating the DAG);
      3-10 - from 1 to 8 seconds delay after each GPU DAG generation before the next one)
  -gpureset <n> Fully reset GPU when paused (0 - no, 1 - yes; default: no, except on 1080Ti). You may specify this option per-GPU.
  -altinit Use alternative way to initialize AMD cards to prevent startup crashes
  -rvram <n> Minimum free VRAM in MB (-1: don't check; default: 384 for Windows, and 128 for Linux)
  -wdog <n> Enable watchdog timer: 1 - yes, 0 - no (1 is the default). The watchdog timer checks
      periodically if any of the GPUs freezes and if it does, restarts the miner (see the -rmode
      command-line parameter for the restart modes)
  -wdtimeout <n> Watchdog timeout (30 - 300; default 45 seconds). You can use this parameter to increase
      the default watchdog timeout in case it restarts the miner needlessly
  -rmode <n> Selects the restart mode when a GPU crashes or freezes:
     0: disabled - miner will shut down instead of restarting
     1: restart with the same command line options - this is the default
     2: reboot (shut down miner and execute reboot.bat)
  -log <n> Selects the log file mode:
     0: disabled - no log file will be written
     1: write log file but don't show debug messages on screen (default)
     2: write log file and show debug messages on screen
  -logfile <name> Set the name of the logfile. If you place an asterisk (*) in the logfile name, it will be
      replaced by the current date/time to create a unique name every time PhoenixMiner is started. If there
      is no asterisk in the logfile name, the new log entries will be added to end of the same file. If you
      want to use the same logfile but the contents to be overwritten every time when you start the miner,
      put a dollar sign ($) character in the logfile name (e.g. -logfile my_log.txt$).
  -logdir <path> Set a path where the logfile(s) will be created
  -logsmaxsize <n> Maximum size of the logfiles in MB. The default is 200 MB (use 0 to turn off the limitation).
      On startup, if the logfiles are larger than the specified limit, the oldest are deleted. If you use a
      single logfile (by using -logfile), then it is truncated if it is bigger than the limit and a new one
      is created.
  -config <name> Load a file with configuration options that will be added to the command-line options.
      Note that the order is important. For example, if we have a config.txt file that contains -cclock 1000
      and we specify command line -cclock 1100 -config config.txt, the options from the config.txt file will take
      precedence and the resulting -cclock will be 1000. If the order is reversed (-config config.txt -cclock 1100)
      then the second option takes precedence and the resulting -cclock will be 1100. Note that only one -config
      option is allowed. Also note that if you reload the config file with 'c' key or with the remote interface,
      its options will take precedence over whatever you have specified in the command-line.
  -timeout <n> Restart miner according to -rmode after n minutes
  -pauseat <hh:mm> Pause the miner at hh::mm (24 hours time). You can specify multiple times: -pauseat 6:00,12:00
  -resumeat <hh:mm> Resume the miner at hh::mm (24 hours time). You can specify multiple times: -resumeat 8:00,22:00
  -gswin <n> GPU stats time window (5-30 sec; default: 15; use 0 to revert to pre-2.8 way of showing momentary stats)
  -gsi <n> Speed stats interval (5-30 sec; default: 5; use 0 to disable). The detailed stats are still
           shown every 45 seconds and aren't affected by the -gsi value
  -astats <n> Show advanced stats from Web sources (0: no; 1: yes). By default the coin exchange rates are updated every
              4 hours, and the coin difficulty is updated every 8 hours. You can increase these periods by specifying
              for example -astats 12, which will increase update periods to 12 and 24 hours respectively
  -gpow <n> Lower the GPU usage to n% of maximum (default: 100). If you already use -mi 0 (or other low value) use -li instead
  -li <n> Another way to lower the GPU usage. Bigger n values mean less GPU utilization; the default is 0.
  -resetoc Reset the hardware overclocking settings on startup
  -leaveoc Do not reset overclocking settings when closing the miner
