For years now there has been possibilities to increase Bitmain bitcoin miners “antminer” efficiency with custom firmware. It is understandable that Bitmain don’t want their customers to change overclock on their asic miners. OC changes could possibly kill or damage hardware in some cases when chip oc and voltages applied to much. Overclock could kill miner it self or power supply. This is one of the reasons why Bitmain lately locks down their miners firmware, they dont want customers to do any changes on them.
The factory settings are standard, whoever is mining for while now. Knows that from some chips you can get better efficiency, just because quality of every chip is not the same. Lately there is been released an upgrade firmware and manual for Antminer S17 from hiveOS. HiveOS is gpu and asic miner monitoring/remote control. They previous firmware for Antminer S9 and T9 has been very successful. We have done review on this firmware also, and the best feature what Bitmain original firmware does not have is auto-chip tuning. It works very well, basically it finds the most optimal chip oc and the voltages to reach best efficiency.
We have now also tested the new firmware for
Antminer S17, it does perform much better then Bitmain original firmware.On Antminer S17 53TH/s version , air cooled miner we where able to reach 75TH/s @3300 watts. It worked very well and setup is straight forward. It is possible to reach even better performance up to 85 TH/s , but you will need immersion cooling. As with air cooled at 75 th/s our miner chip temperatures where close to 80c at room temperature 15c. Also be careful , Bitmani stock power supply Antminer S17 max power usage is 3500 watts.
hiveOS asic miner the installation guide :
Notes
And now let’s go back to the installation process. There is no universal manual, for S17 and S17 Pro there are 3 versions of stock firmware. Therefore, every particular case has its own manual on the custom firmware installation.
Please note, that all the manual steps which involve using BTCTOOLS can be done via ASIC’s web interface (BTCTOOLS is usually used for a large number of devices).
Preparation Stage (required for all the options):
1 .Download and unzip the following archive:
http://download.hiveos.farm/asic/repo/fw/Antminer/s9k-s9se-st15-st17-installer.zip.
Scan the network using BTC_TOOLS and export the list to csv. From csv, copy the IP list and insert it in ips.ini. In case you don’t have a lot of devices, you can make this list manually. Or use bitmain ipreporter tool.
Go to config.ini and check login and password for the ASIC’s SSH or web interface. If the password for the web interface was changed, the same would be for SSH. Set up FARM_HASH to connect to Hive or API, if necessary.
Download the firmware file (it has to have “Hiveon” in its title):
http://download.hiveos.farm/asic/s17/For S17 and S17 Pro, we offer the same firmware file. However, there are two options: “signed” and “nosigned” firmware. The signed firmware can be updated ONLY to another signed Hiveon firmware via ASIC’s web interface or BTC_TOOLS. Third-party or official firmware can’t be installed in this way. However, you can use the rm -rf /etc/bitmain-pub.pemcommand — send it to your ASICs via the Hive web. It will temporarily delete the certificate, but you can reboot your ASIC to bring it back. After this, you will be able to move to any firmware via the firmware update menu (in the Hive web). It will be possible to choose the firmware from the list or to use the URL.
The signed firmware can be downloaded here:
http://download.hiveos.farm/asic/s17/Antminer-S17-S17pro-Hiveon-1.00-sign.tar.gz
If the stock firmware of your ASIC is released before 1 July 2019
Flash your devices with a file from the archive “remsigallbefore_2019–07–01.tar.gz”. This can be done via either ASIC’s web interface or BTC_TOOLS in case you have a lot of devices. You will see an error in status, but this is okay — it should be like this at the moment.
Flash the devices with the firmware file. Again, this can be done via either ASIC’s web interface or BTC_TOOLS.
Launch “3hashfarmforsigned.cmd” from the archive. The ASIC will get connected to the web.
Stock firmware released from July 2019 to December 2019
Launch “1openssh.cmd” from the archive and wait for the script to be performed. The devices will be rebooted. After the reboot, wait for around 3 minutes.
Launch “2upgradereplace.cmd” from the archive and wait for the script to be performed.
Flash the devices with the firmware file (via either ASIC’s web interface or BTC_TOOLS)
Launch “3hashfarmforsigned.cmd” from the archive. The ASIC will get connected to the web.
Please be aware you could damage your hardware by applying new overclock to your Antminer S17 . Biggest downside of this is that there is 2.8% dev fee. I know quality product is never for free, but cheaper option would be better

But we dont need to reach so high to make same gains as 2017. You need actually lot more hardware as the total network hash-rate is growing to kill profitability, then when network is smaller. 2017 /2018 there was no gpus available anywhere. So what would happen if we would need twice as many gpus as they where demanded end of 2017.
