Hi everyone! Lately I’ve been working on creating a custom/CGminer replacement for the G1 mini. What really just started out as a pastime for me has actually resulted in some decent performance and discoveries about the miner. I’m working on a GitHub repo documenting my findings and ill release that when ready. In short, I’ve discovered frequency and voltage values that can be adjusted in the firmware and reverse engineered a lot about how the ASIC talks to the control board.
The question I have is would anyone be interested if i release my miner (or firmware stack) when its finished if it offers slightly better performance? I know there are gripes with using software from randoms on the internet but it will be completely open source. It might also be easily modifiable to suit the G1, however I don’t have access to one to test on. Let me know if anyone is interested!
I have a early version of the custom firmware running at around stock performance (still underclocked for stability) over a 24hr period. Its doing about 1.31-1.34 G/s and is pulling about 14-15 Grin per day on 2Miners. The GitHub repo is also live, and will be updated and corrected as time goes on.
Great! I’ll keep you updated on the progress. Right now I’m just making it a bit more user-friendly and fixing some bugs then i should have it out to test.
What I’ve done is first just take the miner out of its white shell as it seems to block a lot of airflow and recirculate hot air inside. Also I replaced the stock thermal pad on the main ASIC with thermal paste and that seemed to do the trick. That screenshot was actually running with a slight overclock and extra voltage so it goes to show how those two mods really help.
