Firmware for Antminer S19, S19J, S19 PRO S19J PRO - CrMi - ASIC Firmware

Latest firmware for all Antminer S19 versions – CRMI

The firmware for S19 with control cards 7007 and Beagle Bone does not simply make it possible to overclock the Antminer S19 series, increasing its computing power and performance, but also significantly increase its energy efficiency.

Through the use of this firmware, miner not only gets more cryptocurrencies from one ASIC, but also receives a large profit, taking into account the cost of electricity. CRMI firmware opens access to the following ANTMINER S19 work modes:

115 Th / S – 3850 W (33 W – Th / S)
125 Th / S – 4600 W (37 W – Th / S)
140 TH / S – 6100 W (43 W – Th / S)

For comparison, the default firmware, which is installed on ASIC provides only 90 TH / S when consumed at 3100 W (34 W – TH / S)

In other words, the CRMI firmware gives the user the possibility of a flexible choice of the ASIC mode and receiving the advantages that it is required.

The more perfect firmware is one of the key differences between the versions of the ANTMINER ASIC models from its basic options. Differences among chips, modifications of power supplies and cooling systems are certainly also matter, but the key factor is the firmware. However, even Pro firmware from Bitmain does not allow fully revealed the potential of the ASICs.

Custom firmware are still significantly superior to the stock on the performance and energy efficiency of the ASICs. Moreover, they allow you to more flexibly configure the parameters of the work of ASIC, adapting them to the specific conditions and needs of the miner. And this is especially true for Pro versions of Antminer 19 – in the end, you have the right to receive maximum possible functionality for your money.

The firmware from the CRMI for professional versions of the Antminer S19 series of ASICs provides the following modes of operation:

S19 Pro / S19j Pro – 125 Th / S – 3800 W (30 W / Th / S)
S19 Pro / S19j Pro – 140 Th / S – 4600 W (33 W / Th / S)
S19 Pro / S19j Pro – 170 Th / S – 6200 W (36 W / Th / S)

For comparison: stock firmware provides only 110 TH / S for S19 Pro and 104 Th / S for S19J Pro. Moreover, the promised Hashrate of the new flagship Bitmain – S19 XP, which will be released only in this fall, is 140 th / s. So the benefit from the use of custom firmware is obvious.

There are two versions of the control board for all S19 models, which can be made updating the Custom firmware. These are control cards 7007 and Beagle Bone. The firmware for the Beagle Bone has a separate installation file, all files for download are after the instructions.

The Beagle Bone control card is fairly easy to distinguish from others, since the card reader is located inside the case – in order to insert a SD card in the reader, ASIC will have to open.

At the same time, strictly speaking, the new firmware is not installed – the ASIC manufacturer has blocked this feature – the device is simply started with an SD card, ignoring the internal drives containing the stock firmware.

That is, the installation process in practice turns out to be extremely simple:
