This document presents performance benchmark data for UMC OS, a custom Antminer firmware and bitcoin mining firmware platform designed to optimize efficiency, stability, and hashrate performance across ASIC mining hardware.

The ePIC UMC OS platform delivers advanced custom firmware capabilities engineered to improve operational efficiency and performance across modern ASIC mining fleets. This benchmark overview demonstrates how ePIC’s bitcoin mining firmware enhances real-world mining output through automated optimization, intelligent thermal management, and dynamic hashrate control.

UMC OS combines firmware intelligence with the Universal Mining Controller ecosystem, enabling miners to leverage existing hardware while gaining access to Perpetual Tuning technology. This system continuously adjusts voltage, clock speeds, and power consumption to maintain target hashrate levels while preventing thermal shutdowns and instability. Performance benchmarks across multiple Antminer models—including S21, S19 XP, and S19 Pro platforms—show measurable improvements ranging from approximately 10% to 25% increased performance compared to stock configurations.

Designed for both institutional operators and large repair or hosting environments, this custom Antminer firmware supports flexible deployment models including dev fee, licensing, or upfront ownership structures. A fully documented API and compatibility with third-party fleet management software enable automation and scalable infrastructure control.

As a next-generation bitcoin mining firmware solution, UMC OS provides miners with enhanced efficiency, faster deployment, and long-term operational optimization backed by engineering-driven performance validation.

This comprehensive guide explains how to install custom firmware on compatible Antminer models using ePIC’s UMC OS and the RigRunner installer. Designed for miners running Amlogic stock control boards, UMC OS provides a powerful alternative to hardware replacement by delivering advanced bitcoin mining firmware features directly onto existing equipment.

The guide walks users through system requirements, compatible stock firmware versions, and step-by-step installation instructions for both Windows and macOS. With RigRunner, fleet operators can scan IP ranges, detect miners, and deploy firmware at scale without command-line complexity. Once installed, users gain access to ePIC Webdash for real-time monitoring, cooling configuration, pool management, and advanced performance tuning.

Key features include Perpetual Tune (Voltage Optimizer, ChipTune, and Board Tune), overclocking capabilities, hashrate targeting, voltage optimization, and intelligent thermal throttling. The firmware supports popular Antminer models including S19j, S19 XP, S19K Pro, S21 series, and T21, making it a versatile custom Antminer firmware solution.

Operators can choose between a license key or a competitive 1.5% dev fee model, providing flexibility in operational strategy. For miners seeking stability, efficiency, and granular control, UMC OS represents a scalable, performance-driven bitcoin mining firmware solution optimized for modern mining infrastructure.
