Table of contents

T-Rex is a closed source miner for NVIDIA graphics cards only. The program has a 1% commission that goes to developers. This software is available for Windows and Linux and supports CUDA 10.0, CUDA 9.2 and CUDA 9.1.

This guide assumes that you already have a wallet for the coin you will be mining and have chosen a reliable mining pool.

 

How to start

  1. Download program
  2. Unzip
  3. Create new or edit ready-made.bat files by entering information about the pool and wallet of the coin

The contents of the program folder looks like this:

list of files

The folder contains full instructions in Russian and.bat files with a coin and a pool. In order to set up mining for your wallet, you need to edit the.bat file or create a new one by analogy with the existing one.

How to customize or modify a.bat file

Right-click on the file, select "Change".

how to change a batch file

A text document will open and you will see a list of program commands. The -u switch is responsible for the address of the digital wallet. It also needs to be replaced.

However, for those who are interested in the full configuration of the program, we will consider the contents of the batch file in more detail.

Below we will consider the settings for the batch file for different coins.

Settings for Ethereum (ethermine)

  1. t-rex is the name of the program that will be launched using the.bat file.
  2. -a ethash is the name of the coin mining algorithm. The list of available algorithms is listed above.
  3. -o stratum + tcp://eu1.ethermine.org specify the pool address. The -o stratum+tcp:// construct is required.
  4. :4444 after the address of the pool, put a colon and indicate the port of the pool.
  5. -u 0x3aa3e06C47caDEf96202D378aB7C407CF46A36A4 after the -u key, specify the address of your digital wallet.
  6. -w rig0 specify the name of the worker. This is the name of the farm. Specify as you see fit.

Here's some sample code:

t-rex.exe -a ethash -o stratum+tcp://eu1.ethermine.org:4444 -u 0x3aa3e06C47caDEf96202D378aB7C407CF46A36A4 -p x -w rig0
pause

If you write a command pause at the end of the batch file, the console will not close, even if there is a syntax or other error.

Note! Extra spaces, punctuation marks and other symbols are not allowed in the syntax of the batch file. Everything should be as in the example. Only change the wallet to your own.

Settings for Nicehash

  1. t-rex is the name of the program that will be launched using the.bat file.
  2. -a ethash is the name of the coin mining algorithm.
  3. -o stratum+tcp://daggerhashimoto.eu-west.nicehash.com specify the pool address from niceash.
  4. : 3353 after the pool address we put a colon and indicate the pool port.
  5. -u 3HHG3zpxP4AmbKDR9iRy1c2bqAb4WKhNwm after the -u switch, specify the address of your digital wallet from the nicehash program account.
  6. -w rig0 specify the name of the worker. This is the name of the farm.

Here's some sample code:

t-rex.exe -a ethash -o stratum+tcp://daggerhashimoto.eu-west.nicehash.com:3353 -u 3HHG3zpxP4AmbKDR9iRy1c2bqAb4WKhNwm -p x -w rig0
pause

Settings for Binance Pool

  1. t-rex is the name of the program that the baht file will run.
  2. -a ethash is the name of the coin algorithm.
  3. -o stratum + tcp: //ethash.poolbinance.com specify the address of the binance exchange pool.
  4. : 8888 after the pool address we put a colon and indicate the pool port.
  5. -u username1 after the -u key, specify the login from the binance exchange account.
  6. -w rig0 specify the name of the worker. This is the name of the farm.

Here's some sample code:

t-rex.exe -a ethash -o stratum+tcp://ethash.poolbinance.com:8888 -u username1 -p x -w rig0
pause

Just change the username after the key -u to your account name.

Batnik for Ravencoin (RVN)

  1. t-rex the name of the program that will be launched using the.bat file
  2. -a kawpow the name of the mined coin algorithm.
  3. -o stratum + tcp: //rvn.2miners.com specify the pool address. The -o stratum + tcp: // construct is required
  4. : 6060 after the pool address put a colon and indicate the pool port
  5. -u RKAeArXkWLNERjWo5YF3R1xFnYCwKf11sX after the -u key we indicate the address of your digital wallet
  6. .rig specify the name of the worker. This is the name of the farm.
  7. -i 20 set the intensity of the program

Here's some sample code:

t-rex.exe -a kawpow -o stratum+tcp://rvn.2miners.com:6060 -u RKAeArXkWLNERjWo5YF3R1xFnYCwKf11sX.rig -p x -i 20
pause

Batnik for Firo (zcoin)

  1. t-rex the name of the program that will be launched using the.bat file
  2. -a mtp is the name of the coin mining algorithm.
  3. -o stratum + ssl: //zcoin.mintpond.com specify the pool address. This example uses the construct stratum+ssl://. SSL is a secure connection. It is safer, however some PCs experience connection failures via ssl.
  4. : 3005 after the pool address put a colon and specify the pool port
  5. -u aMLjCeLBmBGEJP6dYtWEMdZZuPH4w6uFsK after the -u switch, specify the address of your digital wallet.
  6. .rig0 specify the name of the worker. This is the name of the farm.

Here's some sample code:

@echo off
:start
t-rex -a mtp -o stratum+ssl://zcoin.mintpond.com:3005 -u aMLjCeLBmBGEJP6dYtWEMdZZuPH4w6uFsK.rig0 -p x
goto start
pause

This example uses a restart loop. The teams :start and are responsible for it goto start. Read more about how to automatically restart the miner if it stops working in Windows.

So, we have configured the program to mine various coins. By analogy, other coins are configured on other algorithms. We launch our batch file by double-clicking and see what the miner's console window writes to us:

an example of how the software works

  1. Program version
  2. Installed driver version
  3. List of video cards available for mining
  4. Pool address that you specified in the batch file
  5. The wallet address that you specified in the batch file
  6. Coin token or pool password. Pools rarely use a password, so in 90% of cases, you need to specify a token
  7. The program configures the connection to the pool
  8. Pool authorization
  9. The intensity is set to 20. We set it in the batch file with the -i parameter
  10. Current block and network difficulty of the mined coin
  11. The total hashrate of your farm. Hashrate calculator here
  12. Hashrate of one video card
  13. Graphics card temperature
  14. Consumed electricity
  15. Fan blade speed
  16. Efficiency Kh / Watt

This completes the configuration of the program, but we move on to examining all the possible commands.

Using the Watchdog

Watchdog is designed to monitor the state of the miner and restart T-Rex if it crashes or freezes for any reason.

Also, Watchdog can automatically update if a new version is available.

Use watchdog the same way you use T-Rex. Just replace t-rex.exe with watchdog.exe in your bat / script file in order to use it.

We recommend using watchdog to avoid mining downtime and make sure your GPUs are running 24/7.

Using json config

To start T-Rex from the "config.txt" configuration file enter in the batch file: t-rex -c config.txt

Use the "config_example" file as an example to create your own configuration.

Using the http api

There are several handlers available for the HTTP API.

By default, the HTTP API server binds to 0.0.0.0:4067. This means that you can access your miner through external and internal network interfaces.

A typical example of a request structure: http://your_ip:your_port/name

TREX

The "trex" handler is designed to display the miner's monitoring page in your web browser. You can view the statistics of the miner in real time, and change the parameters and configuration of the miner very, very quickly. Also here you will see updates if they become available.

To activate the handler, go to http://127.0.0.1:4067/trex using your web browser.

CONFIG

The "config" handler is designed to change your configuration on the hard disk, as well as to quickly change some parameters of the miner.

You can change several parameters with one request. GET and POST requests are supported.

If you use config (in a running miner, for example, like this: t-rex.exe -c config_file), then any action with the "config" handler will be saved in the selected config_file.

You can use this handler for automation purposes, such as changing the configuration while doing work, shutting down the miner via the API, and then restarting it with the new parameters applied.

Examples of using GET:

http://127.0.0.1:4067/config?protocol-dump=true

Will dump the protocol and write it to config_file.

http://127.0.0.1:4067/config?algo=x16r&devices=0,1&intensity=20,21

If you use this configuration, it will write the following configuration settings to it:

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 the settings to the "test.conf" file, which will be created in the folder where the miner is located.

algo=x16r
devices=0,1
intensity=20,21 

http://127.0.0.1:4067/config?config=test.conf

Save your current miner settings to a "test.conf" file.

http://127.0.0.1:4067/config

Shows you the current state of the configuration

http://127.0.0.1:4067/config?hashrate_avr=10&temperature-limit=70&temperature-start=40

Will set the following parameters. Everything happens very quickly.

hashrate_avr=10
temperature-limit=70
temperature-start=40

Examples of using POST:

For POST requests, you must use the correct json object with the parameters you want to change.

http://127.0.0.1:4067/config

POST payload:

{
"hashrate_avr": 10,
"temperature-limit": 70,
"temperature-start": 40
}

The name and type parameters in json are identical to the json config parameters you are using.

Summary

The "summary" handler is designed to display all information about the current mining process.

To activate the handler, go to http://127.0.0.1.1:4067/summary using your web browser.

}

Control

The "control" handler is required to configure the T-Rex timer in real time.

The following commands are supported since API 1.3.

Shutdown

To terminate your miner with a GET request type, type in the address bar of your browser and press Enter:

http://127.0.0.1:4067/control?command=shutdown

Hashrate-avr

To change the sample size of the real-time average hash rate with the GET request type, type in the browser line and press Enter:

http://127.0.0.1:4067/control?hashrate-avr=1

It will be established for 1 sec.

gpu-report-interval

To change how often GPU reports appear in the log, type the following command in your browser and press Enter:

http://127.0.0.1:4067/control?gpu-report-interval=10

Now you will see GPU statistics every 10th fraction.

you can disable statistics (enter quiet mode) by setting gpu-report-interval to 0.

no-color

To disable color output in the console, type in the address bar of your browser and press Enter:

http://127.0.0.1:4067/control?no-color=true

Turn on:

http://127.0.0.1:4067/control?no-color=false

protocol-dump

 

To enable the dump of the user's log into the console / log, type in the address bar of the browser and press Enter:

http://127.0.0.1:4067/control?protocol-dump=true

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

To set a time limit in seconds for the miner (it will be disabled after a timeout), enter the following line in the browser line and press Enter:

http://127.0.0.1:4067/control?time-limit=120

After this request, it will turn off your miner after 120 seconds.

Disable:

http://127.0.0.1:4067/control?time-limit=0

If you prefer POST, set the request body to {"time-limit": 120}.

Troubleshooting

The program hangs at startup

If the program freezes at startup, then try to slightly lower the intensity -i 19.

If this does not help, then try to lower the overclocking of video cards or remove it altogether.

The program crashes

If the program crashes after some time, then do the following:

  1. increase the swap file

  2. remove environment variables from old miners. System properties / advanced system parameters / environment variables - remove variables from old programs. Don't delete system variables! Remove only those starting with GPU_FORCE and reboot the system

  3. reduce overclocking
  4. check all contacts from risers and power supply (with the system off). Sometimes it helps to swap the riser.
  5. make sure the power supply is sufficient for the load. Different mining algorithms consume different amounts of electricity
