The BM1387 ASIC Chip
The world’s first bitcoin mining ASIC based on the 16nm process node
Bitmain’s BM1387 chip is built using TSMC’s 16nm FinFET technology and, delivering a record-breaking 0.098 J/GHs, is the world’s most efficient bitcoin mining chip in the consumer market. Each Antminer S9 employs 189 such chips to deliver more hashrate and efficiency than any bitcoin miner ever made.
A Compact Time-tested Design
World’s most powerful bitcoin miner, yet smaller than many portable boom-boxes
The Antminer S9 follows the same form factor as that of the hugely popular Antminer S7 and is nearly the same size. Yet it has more than thrice the power and twice the efficiency of the S7. Each Antminer S9 employs 189 such chips to deliver more hashrate and efficiency than any bitcoin miner ever made.
Controlled by a Dual ARM® Cortex®-A9 Microprocessor
S9’s control board uses a Xilinx® Zynq®-7000 series FPGA with a Dual ARM® Cortex®-A9 microprocessor
Bitmain’s engineering team understood the importance of every detail while working to make the world’s most power-efficient yet powerful Bitcoin miner. The Antminer S9’s control board employs the fast Dual ARM® Cortex®-A9 microprocessor with CoreSight™ and supports Gigabit Ethernet to ensure that mined blocks are submitted instantly.
Engineered to Remain Powerful Yet Cool
A high-grade aluminium case, customized heat-sinks and two computer-controlled fans to keep it cool
The S9 utilizes a combination of conduction and convection cooling to make the world’s most powerful miner perform best without getting hotter than any other terahash bitcoin miner.
Every chip of the S9 is fitted with custom-made heat sinks that are made of a high-grade Aluminium alloy. The case of the S9 is made of the same material. Two computer-controlled high speed fans on both ends of the “tube” ensure that the hot air is rapidly replaced by cooler air at the required pace.
Ease of use
Antminer’s user interface has been carefully designed keeping the needs of our users in mind
After you have accessed the Antminer’s user interface, all you need to do is to enter your wallet address and mining pool settings to start mining.
The user interface also allows you to customize certain settings and to upgrade to new firmware releases from Bitmain.
Important notes about shipping and connecting the power supply
Please select the correct address for shipping before you submit your order because the shipping address cannot be changed after the order has been submitted.
Power consumption figures will vary with your PSU’s efficiency, the ambient operating temperature and the accuracy of the power meter. You will need an ATX PSU. BitShrimp recommends the APW3++ for the S9 miners. It cannot power more than one miner.
There are 3 PCI-e connectors for +12V DC input on each hashing board and all 3 need to be connected to the PSU for the hashboard to operate. Do not connect more than one PSU to the same hashing board!
Separate power supply to control board: there is one additional 6-pin PCI-e connector on the IO board which must be connected to the PSU to get power.
Be sure to power on the miner only after all the 10 x PCI-e connectors are connected to power supply.
