Got a question the other day about how to autotune an L3+ with aftermarket firmware. There are several firmwares out there that you can do this with, however I’ll stick to HiveOS as it has the most flexibility I’ve found, all the way down to the individual ASIC level. While HiveOS isn’t the only one out there, and I’m not saying it’s the best, it’s fairly simple and straight forward and easy to learn to use.
When I hear autotune I get a little worried. How does it know exactly what I want or what I need, or how can it change without a complete understanding of the setup. I treat it like a starting point, it’s a good feeler for what the board can handle, but at the end of the day I always go in and manually setup the boards as that will give me the maximum benefit with the longevity of the hash boards I’m looking for.
HiveOS states they attempt to make the hash rate the highest with the lowest power consumption, and they do pretty good. However what they state in the FAQ doesn’t seem to line up with what I’ve experienced it doing. First off, they state they start with a high voltage and work down, it appears the opposite works and in fact sometimes they needlessly raise the voltage to get rid of a few HW errors that don’t really affect performance. So they’re actually costing you money by using more power even though the HW errors were so minimal (#nonce still under 0.03%.)
That being said, it is a good starting point to understand what your unit is capable of.
