--coin Set coin name.
Helps avoid DAG rebuilds when switching back from a dev fee session.
Example: "etc" for Ethereum Classic, "etc+zil" for Ethereum Classic + Zilliqa mining.
--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.
--ab-indexing Afterburner indexing (same as default but starts from 1).
--devices-info Print list of available CUDA compatible devices in the system.
-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)
--dual-algo Second algorithm to use in dual mining mode.
--dual-algo-mode Controls GPU behaviour in dual mining mode (default: a12).
Format: <algo>:<tuning coefficient>
"<algo>" can be one of: "a1" (first algorithm), "a2" (second algorithm), "a12" (both - dual mining)
"<tuning coefficient>" is optional, and can be either
"rXX" ("dual ratio" coefficient set to XX), or
"rXX:lrYY" ("dual ratio" coefficient set to XX, "LHR dual ratio" coefficient set to YY), or
"hXX" (primary algo hashrate percentage XX).
See dual mining guide for more details.
--profit-per-mh Estimated profitability of the algorithms in dual mining mode per 1MH of hashrate.
Used for fine-tuning algo1/algo2 proportion, the miner will try to maximise the earnings.
Format: <profit_algo1>:<profit_algo2>.
Example: --profit-per-mh 0.0516:0.0012
--lhr-tune [Ethash, Autolykos2] LHR tuning value that indicates the percentage of the full speed the miner
tries to achieve for LHR cards (default: -1). Range from 10 to 95.
-1 - auto
0 - disabled (use for non-LHR cards)
74 - recommended starting value for most LHR cards in low power mode (see --lhr-low-power)
78 - recommended starting value for most LHR cards
Can be set for each GPU separately, e.g.
"lhr-tune": "0,0,77.5,0" - this will set LHR tuning value to 77.5 for the third GPU.
--lhr-autotune-mode [Ethash, Autolykos2] LHR auto-tune mode (default: down). Valid values:
off - auto-tune is disabled. LHR tune value is fixed during mining, and will not change
no matter how often LHR lock is detected
down - LHR tune value will decrease if the miner detects LHR lock
full - same as "down" but additionally miner will be trying to increase LHR tune
value if it's stable on the current LHR tune level
--lhr-autotune-step-size LHR auto-tune step size (default: 0.1).
Indicates by how much LHR tune value is changed by the LHR auto-tuner.
--lhr-autotune-interval LHR auto-tune time interval in minutes (default: 5:120).
Format: <interval_up>:<interval_down>.
"<interval_up>" is the period of time in minutes the GPU must be mining without
hitting LHR locks before the miner attempts to increase the LHR tune value.
If the GPU has tripped LHR, LHR tune value will not decrease if the previous LHR lock
was detected more than "<interval_down>" minutes ago.
--lhr-low-power [Ethash] Reduces power consumption in LHR mode at a cost of a slightly lower hashrate (default: 0).
1 - enabled, 0 - disabled. Can be set to a comma separated string to enable
the mode for a subset of the GPUs (eg: --lhr-low-power 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)
--dataset-mode [Autolykos2] Dataset mode. (default: 2). Valid values:
0 - auto (defaults to 2)
1 - single (each ERGO block the GPU stops hashing until it generates the dataset)
2 - double (the miner generates the dataset for the next ERGO block before it arrives
with a small penalty to reported hashrate, and when the next block does arrive, it
immediately starts hashing without losing 1-4 seconds on creating the dataset).
Memory requirements are doubled in this mode as the GPU has to hold two memory buffers.
If there is not enough memory on the GPU for two datasets, the miner will fall back
to single buffer mode.
--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.
-o, --url URL of the mining pool in the following format: <scheme>://<host>:<port>
Supported schemes: stratum+tcp
stratum+ssl
stratum+http
stratum2+tcp
stratum2+ssl
stratum2 is normally used by Nicehash, MiningPoolHub and other similar mining pools

temperatures above 55 will have yellow color, above 65 - red color. (default: 67,77)
--temperature-color-mem Set memory temperature color for GPUs stat. (default: 80,100)
--temperature-limit GPU shutdown core temperature. (default: 0 - disabled)
--temperature-start GPU core temperature to enable card after disable. (default: 0 - disabled)
--api-bind-http IP:port for the miner API via HTTP (default: 127.0.0.1:4067). Set to 0 to disable.

-------------------- 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.

--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 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)
Example: --fan 45,t:67,tm:95,t:69[45-100],tm:90[50-95]
which translates to
GPU #0: set fan speed to 45%
GPU #1: maintain GPU core temperature at 67C
GPU #2: maintain GPU memory temperature at 95C
GPU #3: maintain GPU core temperature at 69C
with the fan speed limited to [45%, 100%] range
GPU #4: maintain GPU memory temperature at 90C

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.
See https://github.com/trexminer/T-Rex/wiki/API
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.).
Mining calculator: https://woolypooly.com/en/calc/what-to-mine-gpu
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.
