Good Working Second Hand Bitmain Antminer S9J with APW7 Used Bitmain L3 L3 With APW3 BTC LTC Mining Machine In Stock

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.

Special Design Control Board to Reduce Latency

S9’s control board employs the Altera Cyclone® V system-on-a-chip (SoC) built on TSMC’s 28nm low-power (28LP) process technology

Bitmain’s engineering team understood the importance of every detail while working on making the world’s most efficient yet powerful bitcoin miner. The Antminer S9’s control board employs the power-efficient Cyclone® V chip that uses an integrated ARM® Cortex®-A9 processor 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 in mind the needs of our users

After you have accessed the Antminer’s user interface, all you have to do is to enter your wallet address and mining pool settings before you start mining. The user interface also allows you to customize settings and can be upgraded to new releases from Bitmain.
