The purpose of the Awesome Miner Antminer S19 firmware is to improve the hashrate performance, increase the power efficiency and provide more features. This guide is applicable not only for the S19 firmware but also for the L7 and T19 firmware. Sometimes the model name S19 is used to refer to this entire family of models.

The Antminer S19 / L7 / T19 firmware can either be installed directly on the Antminer or run from an SD-card. The Awesome Miner management application can be used to install the firmware on a large number of Antminers with just a few clicks.

Option #1: Install firmware directly on the Antminer (recommended)

  1. See the section Awesome Miner management application below for how to install and get started with the Awesome Miner software. Note: Awesome Miner version 9.10.3 or later is required.
  2. Please identify if you have a control board from Xilinx, BeageBone or AmLogic. See the section Identify control board type for details of how to identify.
  3. To install the firmware via Awesome Miner, go to the toolbar: Tools -> ASIC Tools -> Update firmware. The firmware can be selected from a list and Awesome Miner will automatically download and install the firmware on all selected miners.
  4. Click Apply to perform the firmware upgrade. Awesome Miner will automatically unlock the Antminer to make it possible to install the firmware.
  5. After the installation has completed the Antminer will be rebooted.

Option #2: Run firmware from SD-card

  1. Download the SD-card image via the Awesome Miner Antminer firmware download page. Please note that the SD-card images for S19 are ZIP-files.
  2. Please identify if you have a control board from Xilinx, BeageBone or AmLogic. See the section Identify control board type for details of how to identify.
  3. Extract the ZIP-file to a temporary folder. The ZIP-file contains a single IMG-file.
  4. Download and install the tool BalenaEtcher. 
  5. Use BalenaEtcher to write the IMG-file to an SD-card
    1. Click Flash from file and select the IMG-file extracted in step #3 above
    2. Click Select target and select the SD-card
    3. Click Flash and wait for the operation to finalize
  6. Put the SD-card in the Antminer and start the Antminer. Keep the SD-card in the Antminer all the time as the firmware is running directly from the SD-card, it isn't being installed to the Antminer.

Important steps after the installation

It's important to select a Mining Profile (the hashrate level you want), otherwise there will not be any significant hashrate improvements. The mining profile can either be set via Awesome Miner or the Antminer web interface.

  • Awesome Miner
    • Go to the toolbar: Tools -> ASIC Tools -> Firmware mining profile
    • Select one of the profiles from the list and apply
  • Antminer web interface:
    •  Click the Unlock button in the upper right corner and enter the password (default: "root" or "admin" depending on version) to proceed with the configuration
    • Go to the Mining section and select the Performance tab and use the Preset setting to define the hashrate level to use.

After selecting a Mining Profile, the miner will restart itself a number of times over the next few hours. This is expected and part of the optimization process.

Identify control board type - Xilinx, BeagleBone or AmLogic

The firmware for Antminer S19 is different depending on the control board type. It's important to identify the control board type in order to download the correct firmware type. 

Xilinx

The Xilinx control board has the SD-card reader is located next to the Ethernet port, exposed to the outside of the Antminer.


BeagleBone

The BeagleBone control board has the SD-card reader located on the inside and requires the Antminer to be opened before it can be accessed.


AmLogic

The AmLogic control board doesn't include any SD-card reader. Instead the control board includes a micro USB port. Use Awesome Miner to install the firmware directly to the AmLogic controller.


Awesome Miner management application 

The Awesome Miner application can be used to manage and monitor Antminers and other ASIC miners. When running Antminers with the Awesome Miner firmware, you can manage and monitor these Antminers using Awesome Miner at no additional cost. To get started with Awesome Miner, follow the steps below. If you already use Awesome Miner with a subscription, jump to step #3.

  1. Download Awesome Miner via our web site:
  2. Sign up for an Antminer Firmware license. It's free, you only need to enter your e-mail address to get the license. You can manage any number of Antminers running our firmware with this license.
  3. Add the Antminers to the Awesome Miner application:

Frequently asked questions

How is the firmware installed to the Antminer?

There are two installation methods

1) Install the firmware directly to the Antminer (NAND)

2) Put the firmware on a micro SD card. In contrast to our other Antminer firmware, the Antminer S19 firmware will run directly from the micro SD card. When the Antminer is starting, it will load our firmware from the micro SD-card.

How do I uninstall the firmware?

1) When installed directly to the Antminer (NAND): Download the original Bitmain firmware from their web site and install using an SD-card

2) When running the firmware from an SD card: As the firmware is never installed on the Antminer, you simply remove the SD card. When you start the Antminer without the SD card it will simply load the default Bitmain firmware that is already installed on the Antminer.

What kind of Micro SD can be used?

Antminers can be sensitive about the Micro SD card being used, where cards with larger memory (16 GB or above) may not work in all cases. Bitmain typically recommends 8 GB Micro SD cards or smaller. If you run a larger number of Antminers, please make sure you verify the specific type of SD card is working before ordering any larger quantities.

Is immersion cooling be supported?

Yes

What is the mining fee?

The mining fee is 2.8%. All Antminers running our firmware can be managed and monitored via Awesome Miner at no additional cost.

How much power can the Antminer S19 PSU deliver?

The standard PSU can always handle 3600W and with good cooling conditions 4000W. With even better cooling conditions using immersion cooling, close to 5000W.
