Our new firmware is revolutionizing the world of mining, unlocking the full potential of your miners!

Improved energy efficiency by 15–65%:

• S17 | S17pro up to 25W/1TH;
• T17 up to 39W/TH;

Automated settings based on power consumption or performance profiles;

Automatic per-board voltage and per-chip frequency adjustment — and much, much more!

Why choose OUR FIRMWARE?

Mining optimization: T17 energy efficiency up to 39W/1TH, automatic chip tuning — by boards, by chips, and by profile!

Virus protection: a new web service with threat protection — continuous monitoring and online signature updates. This service ensures reliable protection against existing threats, with an update database that keeps security always up to date.

ASIC overclocking and undervolting: control of frequency, voltage, and profile templates on each hash board (S17 up to 79+TH on air and up to 86TH in immersion baths, T17 up to 60TH). (Overclocking requires mandatory cooling conditions to be met.)

Setting the “immersive” parameter automatically adds profile options for immersion baths to the selection menu:

• S17 (air mode)
• S17 (immersive mode)
• T17 (air mode)
• S17 (immersive enabled)

Updated management interface with built-in wattmeter and counter!

Also: LED alerts for technical issues, with a blinking mode for quick miner identification in the farm.

• Stop mining
• Device restart

New partnership program: We invite large farms, data centers, mining hotels, and major miners to collaborate. Add your own fee into the firmware and generate additional income — with our firmware, it’s easier than ever!

The new configuration interface is simple and convenient:

• A dedicated page for entering required parameters
• Easy fee percentage selection
• Fast saving

Dev Fee — developer reward under 3% of total hashrate, in parallel, without interrupting the main mining process.

Add your own % fee — Redirect ASIC speed %, ideal for hotels and managers to collect part of the payment as a percentage of mining.

SSH vulnerability fix (dropbear)

Improved chip fix algorithm

Implemented a fundamentally new chip startup algorithm developed by us, enabling higher energy efficiency and profitability.

New (configurable) automatic fan control algorithm that improves chip performance, reduces noise, and allows customizable chip temperature. Redesigned board and chip tuning algorithm.

Security settings and antivirus:

• Virus detection and removal.
• Protection against pool substitution by viruses.
• Ability to change SSH port (prevents virus intrusions).
• Warning if the API port is open for write access to the entire network (which could be exploited by attackers) and access control options.
• Backup firmware function (in case the main one was corrupted by a virus).
• It is recommended to change the SSH port.

Monitoring

Watchdog log output added (shows the time and reason for ASIC restarts). Autotune runtime logging added.
Visual monitoring function.

ASIC location option: enables fast blinking of the green LED when one or more chips on a board fail. Red LED fast blinking enabled when a fan speed sensor fails (indicating replacement is needed).
Fixed vulnerabilities discovered in Bitmain firmware.

Loyalty program (to be added soon)

Devfee algorithm improved — now more profitable for the user, not exceeding 2% even on pools with losses.

Standby mode when the internet is disconnected (prevents wasted electricity consumption as happens on stock and other firmware).

Added watchdog timing settings for fixing red chips after tuning. Options: every 30 minutes, 1 hour, 2 hours, 3 hours.

The firmware from mskminer.com is available for free download, but it includes a developer fee of 1.8%–2% (mining is not interrupted, the dev fee runs in parallel with the main mining process). The built-in software from mskminer allows you to achieve higher performance with the same power consumption as Bitmain’s stock firmware and extend the lifespan of your AntMiner up to 5 times thanks to per-chip tuning.

The design closely resembles the original for easier use.

mskminer.com firmware for S9 / S9i / S9j with frequency, voltage, and overclock profile control for each hash board — up to 18+ TH on air and 19–22TH with immersion cooling. (Be careful: overclocking requires a more powerful power supply. You can use 2 standard PSUs or 3 standard 1600W PSUs for 2 Antminers — but never connect one hash board to two different PSUs!)

Firmware Pro v5.0 (Pre) S9-S9i-S9j pre-release — Free, dev fee under 2%
