T-Rex NVIDIA GPU miner (Ethash / Autolykos2 / Kawpow / Octopus / Firopow / MTP)

Overview

T-Rex is a versatile cryptocurrency mining software. It supports a variety of algorithms and we, as developers, are trying to do our best to make it as fast and as convenient to use as possible.

Developer fee is 1% (2% for Octopus and Autolykos2).

Usage

Full list of command line options:

    -a, --algo                     Specify the hash algorithm to use.

        --coin                     [Ethash, ProgPOW] Set coin name.
                                   Helps avoid DAG rebuilds when switching back from a dev fee session.
                                   Example: "eth" for Ethereum, "zil" for Zilliqa.
        --extra-dag-epoch          Allocate extra DAG at GPU for specified epoch. Can be useful for dual mining
                                   of coins like Zilliqa (ZIL). (eg: --extra-dag-epoch 0)
                                   Can be set for each GPU separately by using comma separated list of values
                                   (set to -1 for the GPUs that should not allocate the extra DAG).
        --nonce-start              [Ethash, ProgPOW] Starting nonce for the solution search.
        --nonce-range-size         [Ethash, ProgPOW] Nonce range size for nonce search. The range will be split between all devices.
    -d, --devices                  Comma separated list of CUDA devices to use.
                                   Device IDs start counting from 0.
        --pci-indexing             Sort devices by PCI bus ID. Device IDs start with 0.
        --ab-indexing              Afterburner indexing (same as --pci-indexing but starts from 1).
    -i, --intensity                GPU intensity 8-25 (default: auto).
                                   Controls the GPU workload size, in other words how many nonces the miner is
                                   processing "in one go": N = 2 ^ intensity
        --low-load                 Low load mode (default: 0). 1 - enabled, 0 - disabled.
                                   Reduces the load on the GPUs if possible. Can be set to a comma separated string to enable
                                   the mode for a subset of the GPU list (eg: --low-load 0,0,1,0)
        --lhr-tune                 [Ethash] LHR tuning value that controls the maximum hashrate the miner
                                   tries to achieve for LHR cards (default: 0). Range from 0 to 8.
                                   0 - disabled (use for non-LHR cards)
                                   1 - lowest hashrate, low chance of LHR lock
                                   4 - recommended value for most LHR cards
                                   8 - highest hashrate, high chance of LHR lock
                                   Can be set for each GPU separately, e.g.
                                   "lhr-tune": "0,0,4,0" - this will set LHR tuning value to 4 for the third GPU.
        --kernel                   [Ethash] Choose CUDA kernel (default: 0). Range from 0 to 5.
                                   Set to 0 to enable auto-tuning: the miner will benchmark each kernel and select the fastest.
                                   Can be set to a comma separated list to apply different values to different cards.
                                   (eg: --kernel 2,1,1,3)
                                   The support for this parameter may later be extended to cover other algorithms.
        --gpu-init-mode            Enables DAG sequential initialization (default: 0).
                                   0 - all GPUs are initialized in parallel
                                   1 - fully sequential initialization, one GPU at a time
                                   2 - two GPUs at a time
                                   etc.
        --dag-build-mode           [Ethash, ProgPOW, Octopus] Controls how DAG is built (default: 0).
                                   0 - auto (miner will choose the most appropriate mode based on the GPU model)
                                   1 - default (suitable for most graphics cards)
                                   2 - recommended for 30xx cards to prevent invalid shares
                                   Can be set to a comma separated list to apply different values to different cards.
                                   (eg: --dag-build-mode 1,1,2,1)
        --keep-gpu-busy            Continue mining even in case of pool connection loss.
                                   Useful when a GPU crashes during start/stop cycle that occurs when internet
                                   connection goes down.

                                            (activates "script_to_activate" script once total hashrate drops to 50MH/s)

    ------------------ GPU fine tuning (Windows & Linux) ----------------

        --pl                       Sets GPU power limit (Windows - in percent, Linux - in Watts)
                                   Requires running the miner with administrative privileges.
        --lock-cclock              Specifies desired locked GPU core clock speed in MHz. (default: 0 - disabled).
                                   Requires running the miner with administrative privileges.
                                   Example: --lock-cclock 1000 (applies clock 1000Mhz to all cards that support this functionality)
                                            --lock-cclock 1000,1300,0 (applies clock 1000Mhz to GPU #0, 1300MHz to GPU #1, ignore GPU #2)

        --mt                       Memory tweak mode (default: 0 - disabled). Range from 0 to 6. General recommendation
                                   is to start with 1, and then increase only if the GPU is stable.
                                   The effect is similar to that of ETHlargementPill.
                                   Supported on Pascal GPUs with GDDR5 or GDDR5X memory only.
                                   Requires running the miner with administrative privileges.
                                   Can be set to a comma separated list to apply different values to different cards.
                                   Example: --mt 4 (applies tweak mode #4 to all cards that support this functionality)
                                            --mt 3,3,3,0 (applies tweak mode #3 to all cards except the last one)

    ------------------ GPU fine tuning (Windows only) ------------------

                                   All options can be set to a comma separated list to apply different values to
                                   different cards. (default value for all options: 0 - not used)
        --fan                      Sets GPU fan speed in percent or target temperature (auto-fan).
                                   Valid formats:
                                      --fan N           (where N is the fan speed)
                                      --fan t:N         (where N is the target core temperature)
                                      --fan t:N[F1-F2]  (same as above, but with the fan speed constrained by [F1%, F2%] range)
                                      --fan tm:N        (where N is the target memory temperature)
                                      --fan tm:N[F1-F2] (same as above, but with the fan speed constrained by [F1%, F2%] range)

JSON config file

To start T-Rex with config file config.txt type in the console: t-rex -c config.txt. Use config_example file as a starting point to create your own config.
If a parameter is set in the config file and also via cmd line, the latter takes precedence, for example: t-rex -c config.txt -w <worker_name_to_override_the_one_in_config_file>
You can also use environment variables: simply put %YOUR_ENV_VAR% anywhere in your config file and it will get automatically substituted with the value of YOUR_ENV_VAR variable at run-time.

Watchdog

Watchdog is intended to observe miner state and restart T-Rex if it crashes or hangs for any reason. Also, watchdog can optionally perform auto updates if a newer version is available. We recommend using the watchdog to avoid any downtime in mining and make sure your GPUs are busy 24/7. If you do need to disable the watchdog, you can do so using --no-watchdog parameter.

HTTP API

By default HTTP API server binds to 127.0.0.1:4067. It means that you can only access your miner from localhost. See --api-bind-http parameter on how to change it. Common example of request structure: http://<ip>:<port>/<handler_name>

Handlers:

  • trex - Shows miner control monitoring page in your web browser.
    You can see miner stats in real time and also change miner parameters and config on the fly. Aside from that you will also see any available updates.

  • config - Changes your config on HDD and also change some miner parameters on the fly.
    You can change multiple parameters with one request. Both GET and POST requests supported.
    If you use a config file (e.g. t-rex.exe -c config_file), then any action with handler config will be saved into config_file.
    You can use this handler for automation like changing config file at run-time, shutting down the miner via API and then restarting it with new parameters applied.

    GET usage examples:

    • http://127.0.0.1:4067/config?protocol-dump=true
      Enables protocol dump on the fly and write it into config_file
    • http://127.0.0.1:4067/config?algo=x16r&devices=0,1&intensity=20,21
      Writes the following config settings into the config file: algo=x16r, devices=0,1, intensity=20,21
    • http://127.0.0.1:4067/config?algo=x16r&devices=0,1&intensity=20,21&config=test.conf
      Saves settings into the file test.conf which will be created in the folder where the miner resides: algo=x16r, devices=0,1, intensity=20,21
    • http://127.0.0.1:4067/config?config=test.conf
      Saves your current miner settings into test.conf file
    • http://127.0.0.1:4067/config
      Shows the current config state
    • http://127.0.0.1:4067/config?hashrate_avr=10&temperature-limit=70&temperature-start=40
      Sets the following parameters on the fly: hashrate_avr=10, temperature-limit=70, temperature-start=40

    For POST requests you must use correct json object with parameters you want to change:
    URL: http://127.0.0.1:4067/config.
    Payload: {"hashrate_avr": 10, "temperature-limit": 70, "temperature-start": 40}.
    Parameter names and types in json are identical to config json you normally use.

Antivirus alerts

In order to protect the miner from reverse engineering attacks, the binaries are packed using a third-party software which mangles the original machine code. As a result, some antivirus engines may detect certain signatures within the executable that are similar to those that real viruses protected by the same packer have. In any case, it is advisable not to use cryptocurrency miners on the computers where you store your sensitive data (wallets, passwords etc.).

Tips

In order to maximise the hashrate our software utilises all available GPU resources, so it is important that you review your overclock settings before you start mining. Our general recommendation is to start from GPU stock settings (no overclock, default power limit), and then after making sure it is stable, slowly increase your overclock to find the "sweet spot" where the miner performs at its best and still does not crash.
