T-Rex v0.15.7 (NVIDIA GPU miner) – It is a universal cryptocurrency mining software. It supports many algorithms, and we, as developers, try to make it as fast and easy to use as possible. DevFee 1-3% – Development fee is 1% (3% for Tensority).
Please note miners are often marked as malware by antivirus programs. This is not so, they are marked simply because they are cryptocurrency miners. If you do not trust the software, do not use it!

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. 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 hungs 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 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://your_ip:your_port/handler_name
trex – Shows miner control monitoring page in your web browser. You can see miner stats realtime and also change miner parameters and config on the fly. Also here you will see updates in case it appears. To activate the handler navigate to
http://127.0.0.1:4067/trex
using a web browser.log Displays the contents of the log file (if configured). To activate the handler navigate to
http://127.0.0.1:4067/log
using a web browser.config – Changes your config on HDD and also change some miner parameters on the fly. You can change multiple parameters with one request. GET and POST requests supported. If you use config (started miner like this: t-rex.exe -c config_file) then any action with handler “config” will be saved into selected config_file. You can use this handler for automatization purposes like changing config at runtime, 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
– Will write 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 filetest.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 intotest.conf
filehttp://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}
. Parameters’ names and types in json are identical to config json you normally use.summary Shows all information about current mining process. To activate the handler navigate to
http://127.0.0.1:4067/summary
using a web browser.

control Real time configuration of T-Rex miner. As of API 1.3 version there are following commands supported.
shutdown – Shuts down your miner. Usage:
http://127.0.0.1:4067/control?command=shutdown
. If you prefer POST set the request body to{"command": "shutdown"}
.hashrate-avr – Changes sliding window size in real time. Usage:
http://127.0.0.1:4067/control?hashrate-avr=1
. It will set sliding window of size 1 sec. If you prefer POST set the request body to{"hashrate-avr": 1}
.gpu-report-interval – Changes frequency of GPUs reports appearance in log. Usage:
http://127.0.0.1:4067/control?gpu-report-interval=10
. Now you will see GPUs stats every 10th share. If you prefer POST set the request body to{"gpu-report-interval": 10}
. Btw, you can disable stats (enter quiet mode) by setting gpu-report-interval to 0.no-color – Disables color output to console. Usage:
http://127.0.0.1:4067/control?no-color=true
. To enable:http://127.0.0.1:4067/control?no-color=false
. If you prefer POST set the request body to{"no-color": true}
.protocol-dump – Enables user protocol dump into console/log. To enable:
http://127.0.0.1:4067/control?protocol-dump=true
. To disable:http://127.0.0.1:4067/control?protocol-dump=false
. If you prefer POST set the request body to{"protocol-dump": true}
.time-limit – Sets time limit in seconds for miner (it will shutdown after timeout). Usage:
http://127.0.0.1:4067/control?time-limit=120
. It will shutdown your miner 120 seconds after this request. To disable:http://127.0.0.1:4067/control?time-limit=0
. If you prefer POST set the request body to{"time-limit": 120}
.file Creates a file in directory with the miner. This may be useful for external monitoring utilities or scripts which can take commands from this file and do some sort of useful stuff like overclock or system reconfiguration.
http://127.0.0.1:4067/file?name=test.txt&data=some_sort_of_text_data
If you prefer POST set the request body to
{"name": "test.txt", "data": "some sort of text data"}
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.
