We can choose to stay in the option for this situation. (2) The hash rate is 0.5T higher than the target:įor example, the miner hash rate is 14T, select +2T option, the actual hash rate reaches 16.5T. In this case, we can stay in the current setting or downgrade the option to +1.5T. (1) The hash rate is 0.5T less than the target:įor example, the miner hash rate is 14T, select +2T option, the actual hash rate reaches 15.5T. Normal situations after using over frequency option.Over temperature protection (real-time hash rate is 0), lack of hash boards or chips, insufficient hash rate and so on. Unable to supply current over frequency option, power failure and so on. (1) Power supply has the following issues: The conditions recommended to use a lower over frequency option.If the miner can run in +1.5T option with a stable condition, considering the power supply and room temperature, it is then possible to continue to select +2.0T option if +1.5T option is not stable, it is suggested to downgrade the option to +1.0T/+0.5T. If it is stable, then select +1.5T option. (3) You can refer to the following suggestions to use over the frequency options:įirst, run in the “Normal” option for some time. Note: Considering conditions, due to the difference between the power supply and miners, Evenif the power supply is within the recommended range, it may not work properly. +1.0T/+1.5T/+2.0T options can be supported by 1600W power supply.ġ600W power supply can support up to 12T hashrate after the over-frequency.ġ800W power supply is needed if the hashrate is equal or more than 12.5T after the over-frequency. +0.5T option can be supported by 1400W power supply, Power Supply Requirement and Option Adjustment Suggestions.Power below 1400W, unstable power supply, etc. (2) Power supply has the following issues: While running the normal firmware, the hash rate is more or less 5% less than the ideal hash rate, lacks hash boards or chips, unstable hash rate, etc. Bitmain Antminer S9 13.5 TH/s miner that can produce at a maximum of 13.5 TH/s hash rate with 1.323 KW power consumption. NOT Recommended to Upgrade to Multi-Option Firmware.Increasing the working frequency, expect to improve from 0.5~2.0TH/S respectively based on the initial ideal hash rateĭecreasing the working voltage and working frequency, hash rate remains unchanged, reducing the power consumptionĭecreasing Hash rate by 0.5~3.0TH/S respectivelyĭecreasing working voltage and frequency, hash rate will be decreased by around 4.5TH/S for S9 and 3.5TH/S for S9i/j respectively, reducing the power consumption Normal working mode, the working voltage and frequency remain unchanged ![]() The multi-option drop-down menu screenshot of T9+ is as follows: The multi-option drop-down menu screenshot of S9/S9i/S9j is as follows: It is suggested that using Antpool/BTC.com tools to set the option simultaneously for multi miners. You can choose the appropriate option to improve the hash rate, or choose the corresponding option to reduce the power consumption. If it is C5, firmware will skip the upgrade and the version number of the miner will not be changed after the operation.Ī drop-down menu of “Working Mode” has been added to the “Miner Configuration” web page of the miner. ![]() The firmware will automatically check the type of control board. It doesn't matter to upgrade the new firmware by mistake. ![]() The firmware does not support the miners which are using the C5 control board(only for few of S9 miners). You can also mine bitcoin through a cloud mining contract with Genesis Mining as well as other cloud mining contracts that can be found here.Four multi-option security firmware have been released to support S9, S9i, S9j and T9 + miners respectively. Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter. Power Efficiency: 0.10 J/GH + 7%(at the wall, with APW3 93% efficiency, 25☌ ambient temp) Power Consumption: 1375W + 7% (at the wall, with APW3 ,93% efficiency, 25C ambient temp ) The power consumption is at the all-time low of 0.098 J/GH – the consumption is rated at 1450W only. Antminer S4 can reach 2 TH/s hashrate and 1400 W power consumption for mining BTC (SHA-256) earning. This miner has an hashrate of 13.5TH/s!Ĭarrying 189 BM1387 chips, the S9 is the most energy efficient Bitcoin miner in the world so far. You are looking at one of the most powerful Bitcoin miners in the world, the Antminer S9.
