The Bitmain Antminer V9
In the past days, I have been reviewing various miners. Today, I will be giving a run through about how to set up a Bitmain Antminer V9 SHA256 miner! I'll also give the specs of the device, do a short review, and run through some do's and don'ts about this machine.
- Algorithm: SHA256 (Bitcoin, BitcoinCash, Peercoin, etc.)
- Hashrate: 4 TH/s +/- 5%
- Chip: 135 x 16nm Bitmain BM1580 chips
- Power use: About 1027 Watts with the APW3++ External Power Supply Unit (PSU)
- Noise: 76dB
- Interface: Ethernet
- Fan Speed: Front: 6000 rpm. Rear: 4500 rpm.
Set Up Part 1: Inspection
When you first receive the miner, make sure you look for signs of damage on the packaging. If there is damage, take photos of the damage before opening the package. If both the package and the miner are damaged, contact customer support. Then, inspect the miner for external damage such as dents, broken fan blade, damaged cables, etc. From the front and back of the miner, peer inside to check if any heat sinks broke loose. If you find any damage, report it to customer support.
Set Up Part 2: Plugging it in
The Antminer V9 has 3 hashboards, each with three PCIE connectors. The control board also has a PCIE connector. There are 10 power connections in total that need to be attached to a 12 volt power connector, preferably to an APW3++ power supply unit plugged into a wall. Next, make sure that the ethernet cable is plugged into a Wi-Fi router that a computer you are using for the setup is also connected to. The miner and computer MUST be on the same network or else Set Up Part 3: Mining will not work.
Set Up Part 3: Mining
First off, you will need to power up the miner and wait for the "normal" light (the green one) to start flashing. Then, download Bitmain's IP search software from https://service.bitmain.com/support/download . Once you open the program on your computer, press start and press the "IP Report" button on the V9. The miner's IP address will be displayed.
On your computer, type the displayed IP address into a browser. A dialog box will pop up and ask for login credentials. The default username and password are "root". Once you log in, navigate to the "Miner Configuration" tab and click "General Settings". Here, you can fill out information for your mining pool IP address, worker ID, and password. I highly recommend selecting the option to stop running when internal PCB temperatures exceed 80 Degrees Celsius, as this could permanently damage the Antminer V9. You can also select the freq
Finally, click "Save & Apply" and restart your miner.
Dusty miners could result in increased temperatures, increased fan speeds, and damage to chips or the PCB board. You should check your device regularly for dust. If it's too dusty, power down the miner by unplugging it, and remove the two fans. You can either continue to disassemble the device or simply use compressed air to clean it out. Note that if you don't take it apart, there will still be dust stuck inside!
- Keep the Antminer V9 in a clean, not-dusty environment with unobstructed air circulation
- Allocate about 500 mb of data/WiFi to each miner every month
- Keep the area dry. Humidity could damage the miner (The miner works best with under 65% humidity)
- Unplug the miner when maintaining
- Run the miner is a confined or dusty space
- Run the miner in extreme heat (The miner works best with an external temperature of 5-35 degrees Celsius)
- Use the miner if you found damage
The Antminer V9 was released in 2018, featuring 135 Bitmain 16nm ASIC chips to mine SHA256 coins like Bitcoin and Peercoin. It mines at about 4 TH/s, though you could adjust this to be a bit higher or lower in the settings. However, this miner is not profitable to run anymore, as the price of electricity is enormously higher than the profit from 4 TH/s, especially since modern miners such as Bitmain's Antminer S17+ can mine at nearly 70 TH/s.
Keep in mind that the two fans are extremely loud, and if you're considering running this at home, prepare to embrace the sound of a perpetually active hair dryer. On the other hand, should you pay no electricity fees nor pool mining fees, and considering that the difficulty of Bitcoin stays the same, you'll make just under $230.00 US a year!
I am not in any way affiliated with Bitmain or any other crypto/crypto-related company. I personally have one of these devices initially purchased directly from Bitmain in about late 2018. It was powered by an APW3++ power supply unit. It was still fully functional, with all chips working when I stopped mining on it due to the skyrocketing difficulty.
Remember, investments in cryptocurrencies are like any other investment: Invest only what you can afford to lose. No investment is a guarantee.
