I got it to upgrade to 3/3/2021
Upgrade to today's release, it incorporates more fixes:
NEW RELEASE: Braiins OS+ 21.06
## Overview
This is a major release that provides improved support for the Antminer x17(including e) family. The machines will be auto-upgraded. If you want to force the update right away then use the toolbox (update section).
## Antminer X17
- [feature] improved tuner for all x17 models ensures optimum miner performance at user configured power levels
- [feature] support for S17e and T17e
- [feature] Braiins OS+ Manager support enabled for the entire x17 family
- [feature] improved DPS, Dynamic Power Scaling now also automatically upscales the power limit, when the miner's temperature is at least 5 degrees bellow the HOT limit and the fans are running bellow 80%.
- [feature] BOSminer will run and ignore incorrect configurations only when Braiins OS+ Manager is used so that the configuration can be fixed. If Braiins OS+ Manager is not used, BOSminer will power off when there is an incorrect configuration.
Note: this is the first public release for the S17e and T17e. As always with new releases, we recommend to test it on a few machines before rolling it out to an entire farm.
If you have auto upgrades enabled, during the day or tomorrow the miners will update themselves, otherwise you will have a blue "upgrade" button in the top right corner of the miner's web UI you can use at your convenience to upgrade (single click to it will do it without further confirmation).
Try to stick to changing only the power limit value (with autotuning always enabled). If you want to "lower frequencies", lower the power limit instead and wait for the autotuner to do its job. Do not disable autotuning, and don't bother changing the frequency value directly as this does nothing while autotuning is enabled (true placebo there).
With Braiins OS+ you normally only manipulate the power limit value and nothing else. Less power = lower frequencies and less heat dissipation (better efficiency at the given limit). The unique autotuner is the core value of Braiins OS+ and disabling it would be pointless unless for diagnosing.
Always give time to the autotuner. It can take many hours. Failing boards will be retried later even after the others are already Stable, so giving the miner a day or so to stabilize is a good idea.
While manipulating the power limit, and only after the process is finished (all boards Stable) the fans should NOT be at 100%. Braiins OS+ is more conservative than Stock firmware for the S17/T17 family (due to their infamous bad soldering from factory issue) so it uses lower temperature and power limit values by default. If the fans are at 100% after Tuner Status displays Stable, this means you are above the TARGET temperature for some reason.
So either improving the air flow on site or reducing the power limit to make the miner work less should give a safety margin back for the fans (anything less than 100%) to act when ambient temperature rises for whatever reason. You can also enable Dynamic Power Scaling to have an additional tool in case the Temperature reaches HOT it automatically reduces the power limit the step you define there.
You have it doing 18.xTH per board on the 2 'better' boards, but isn't that what it's supposed to do with standard firmware? (without losing a 2% fee)
So either you lose 2% off that, or it's running 2% harder than what you see to cover the fee and still only getting the expected hash rate?
Fear not, when you use Slush Pool with Braiins OS+, the pool fee is waived. Its even cheaper than yours...
Also, but most important: How many watts the miner is using at that speed vs "standard" (your beloved bmminer)?
