--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)
--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).
--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)
--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 connection loss.
-o, --url URL of the mining pool in the following format: <scheme>://<host>:<port>
Supported schemes: stratum+tcp

--temperature-start GPU temperature to enable card after disable. (default: 0 - disabled)
-b, --api-bind-telnet IP:port for the miner API via telnet (default: 127.0.0.1:4068). Set to 0 to disable.
For external access set IP to 0.0.0.0, in which case setting "--api-read-only" is
recommended as well.
--api-bind-http IP:port for the miner API via HTTP (default: 127.0.0.1:4067). Set to 0 to disable.
For external access set IP to 0.0.0.0, in which case setting "--api-read-only" is
recommended as well.

within "M" minutes.
Format: N:M:A. Valid values:
N: any positive integer,
M: any positive integer,
A: r(system reboot), s(system shutdown), e(miner exit)
Actions "r" and "s" require running the miner with administrative privileges.
Examples:
20:10:s - watchdog will shutdown the system if the miner gets restarted 20 times
within any 10 minute interval
5:7:r - watchdog will reboot the system if the miner gets restarted 5 times
within any 7 minute interval
-B, --benchmark Benchmark mode.
--benchmark-epoch Epoch number used during benchmark (only for algorithms that generate DAG).
-P, --protocol-dump User protocol logging.
-c, --config Load a JSON-format configuration file.
-l, --log-path Full path of the log file.
--cpu-priority Set process priority (default: 2) 0 idle, 2 normal to 5 highest.

--exit-on-connection-lost Forces miner to immediately exit on connection lost.
--reconnect-on-fail-shares Forces miner to immediately reconnect to pool on N successively failed shares (default: 10).
--fork-at Forces miner to change algorithm on predefined condition (works only with built-in watchdog enabled)
Epoch condition: <algo_name>=epoch:<epoch_number> (eg: --fork-at etchash=epoch:390).
Block condition: <algo_name>=block:<block_number> (eg: --fork-at x16rv2=block:6526421).
Time condition: <algo_name>=time:<YYYY-MM-DDTHH:MM:SS>. Time must be set in UTC+0.
(eg: --fork-at x16rv2=time:2019-10-01T16:00:00).
To change main pool port you must write it right after algo: <algo_name>:<port_number>
(eg: --fork-at x16rv2:4081=time:2019-10-01T16:00:00).
--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 graphics cards 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)
--script-start Executes user script right after miner start (eg: --script-start path_to_user_script)
--script-exit Executes user script right before miner exit.
--script-epoch-change Executes user script on epoch change.
--script-crash Executes user script in case of miner crash.
--script-low-hash Executes user script in case of low hash. Hash threshold is set in MegaHashes/second.
Example: --script-low-hash script_to_activate:50
(activates "script_to_activate" script once total hashrate drops to 50MH/s)
--version Display version information and exit.
-h, --help Display this help text and exit.

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 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.
By default HTTP API server binds to 0.0.0.0:4067. It means that you can access your miner via both external and internal network interfaces.
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. -
log - Displays the contents of the log file (if configured).
-
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 handlerconfigwill be saved intoconfig_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_filehttp://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=20,21http://127.0.0.1:4067/config?algo=x16r&devices=0,1&intensity=20,21&config=test.conf
Saves settings into the filetest.confwhich will be created in the folder where the miner resides:algo=x16r,devices=0,1,intensity=20,21http://127.0.0.1:4067/config?config=test.conf
Saves your current miner settings intotest.conffilehttp://127.0.0.1:4067/config
Shows the current config statehttp://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. -

{"name": "test.txt", "data": "some sort of text data"}
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.).
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.
