This is the Open Bitaxe Benchmark Database — a free, openly-licensed record of real operating points for the Bitaxe and open-source (OSMU) miner family. Every row lists the board revision, ASIC chip, frequency, core voltage, hashrate and J/TH efficiency, so you can see exactly what a Gamma, Supra, Ultra, Max or Nerd-family board actually does at a given tune.

It is seeded with spec-derived reference points and grown by the community: run mrv777’s Bitaxe-Hashrate-Benchmark on your own miner and submit the results to add your numbers. The open-source miner family itself comes from skot9000 and the Open Source Miners United community — this database simply collects what they made possible, verifies the chip pairings, and gives it back as open data.

Quick answer

The Open Bitaxe Benchmark Database is a free, openly-licensed dataset of 14 real operating points across 10 open-source miner models (Bitaxe Gamma, Supra, Ultra, Max, the Nerd family and more) — board revision, chip, frequency, core voltage, hashrate and J/TH efficiency. It is seeded from spec-derived reference points and grown by the community using mrv777's Bitaxe-Hashrate-Benchmark tool. Sort it, filter it, download it, or submit your own.

Lowest J/TH wins: undervolt first, then tune frequency to the best hashrate your chip and cooling allow.

This database stands on the shoulders of the open-source mining community. The benchmark methodology and JSON format come from mrv777's Bitaxe-Hashrate-Benchmark (GPL-3.0); the open-source miner family itself was created by skot9000 and the Open Source Miners United (OSMU) community. D-Central curates, verifies chip pairings and hosts the open data — credit flows back to them.

Open-source-miner autotuners (AxeOS) calculate frequency and core voltage at runtime — these are reported operating points, not fixed presets. "Reference" rows are spec-derived from the canonical D-Central chip map; "Community" rows are submitted by miners and moderated before they appear. A ✔ flair marks a unit independently bench-verified by D-Central.
