The Bitaxe Gamma represents a massive leap forward in home mining, becoming the first single-ASIC miner to break 1 TH/s out of the box and potentially reach over 2 TH/s with proper cooling. This comprehensive review tests the fourth-generation Bitaxe across multiple cooling configurations, from basic aluminum heatsinks to advanced copper solutions.
Key Findings:
- Standard Performance: 1.0-1.2 TH/s at stock settings with proper cooling
- Cooling Critical: Cheap yellow coolers fail even at default settings - overheating within minutes
- Minimum Recommendation: Ice Tower with Noctua fan for stable operation
- Sweet Spot: Copper cooler with active case cooling (OC'axe) delivers exceptional efficiency
- World Record Territory: 2.04 TH/s achieved at 1000 MHz with advanced air cooling setup
The Gamma is described as a "temperature diva" - extremely sensitive to heat but rewarding proper cooling with incredible performance. Unlike previous Bitaxe models that needed operating temperature, the Gamma follows "the cooler, the faster" principle. With appropriate cooling investment (Ice Tower minimum), this represents the most efficient and powerful single-ASIC home miner available, though availability remains extremely limited due to massive demand.
Bottom Line: If you can get one and invest in proper cooling, the Gamma delivers unprecedented home mining performance.
