Antminer S17
Antminer S17 is available in two versions: model 56 TH/s and 53 TH/s, with two mining modes. Both models operate at 45 J/TH in normal mode, there is also a low-power operation mode at 42 J/TH. Antminer S17 Pro also comes in two versions: model 53 TH/s and 50 TH/s, with three mining modes that "provide advanced individual customization, thanks to which customers can switch between different settings modes." Both models have an efficiency of 45 J/TH in turbo mode, normal mode works at 39.5 J/ TH, low-cost — at 36 J/TH.
Bitmain stated that the 2nd generation of 7 nm mining chips BM 1397, used in the manner of the 17 series, will save 28.6% of energy consumption compared to last year's developments. With respect to the Antminer S15 series, the new S17 and S17 Pro can save from 26% to 36% of energy consumption.
All ASIC miners are controlled by special software, which, like any program, can be modified to suit various requirements. At the same time, ASIC manufacturers focus on the stability of work, which means that there were as few defects and returns as possible.
That's right. I used this equipment but then decided to buy another model Antminer S17J. I want to say that these two models are very good and completely cope with their work. The firmware is what you need. The devices are flying. Reliable.
Custom firmware usually add additional functionality for overclocking (overclocking) ASIC chips in order to get the most out of their capabilities with a possible loss of stability and equipment life. Since ASICs are the most common, therefore, there are also the most different options for non-factory firmware. I advise you to consider the next variation of firmware for asics of the Antminer S9 and S17 https://ultramining.com/en/firmwares/bitmain/antminer-s17/ generation, which allows you to increase the hash rate of mining equipment by 30%. Replacing the standard firmware with a custom one will increase the hash rate and make the chips downvolt by 15-20%, which will also have a positive effect on energy consumption and, accordingly, on your mining income.
