be constructive or S.T.F.U

Your rejected shares rate isn't perfect but it's also nowhere near bad, it's just normal, also it seems like you have the auto-tuning going on, which will affect the results to some degree, all the information you posted are irrelevant, all that matters is the accepted hashrate that shows on Slushpool if it's within the 1+-% range of what appears on the miner status page - then you have nothing to worry about, of course, the reading should be taken after the miner has been running for a long enough period.

I wasn't really looking for anything, but to make sure that the errors that high are normal, because I had seen others recommending this to not be any higher than .0003.(Something like that). This is my first time around this, and just getting my feet wet.

All the settings are autotuned, I have not set any of the variables manually.

I have an exhaust hooked up to the machine, that are keeping my temps low.

'The right to privacy matters'

I am not sure what it is you are expecting.
your numbers are fine
your temps are fine.

you over clocked and get extra hash and extra errors all is normal.

I can tell you that the gear is close to 15th. if it is close to 15th at the pool call it a day you are done.

also I don't like the 9.3 volt tune on one board but it is not showing a high temp.

Me I would not set the power limit to 1420 watts and auto tune

I would set it to 1200 watts and autotune but I nurse my gear.

You realize your numbers mean for every 100 usd you should earn you are losing 66 cents. you can see what the 1200 watt clock does for lost hash vs 1420 watt clock.

I had rebooted my machine, several times because i was seeing similar stuff happing before also.

Currently, I am 30 hrs in since the last reboot, and the rejection ratio has dropped a tad bit, but not much lower. .66%

The ping time also doesn't seem to be an issue.

Code:

As far as overclocking and voltage, I am using Braiin OS+.

Your kernel log looks fine by the glance of it.
Phil already noted that your unit is only active for 16h and you should wait for at least until 24h pass or even 48h to get a solid average.

Your rejection and HW is not that high but it would be better if it was lower. Rejection can be due to high ping while HW are due to too high overclock and/or too low voltage.

The rejection ratio is pretty small but you have many hardware errors according to your stats.
I think it would be better to bring this issue to their official thread from here https://bitcointalksearch.org/topic/braiins-os-braiins-os-custom-asic-firmware-optimize-performance-efficiency-5036844

Anyway, if you can share your kernel logs here maybe we can see the cause of this why you get 10.32 Th/s on average.

Try to change your pool it might be because of high pool server ping or might be because of high ASIC temp.

his 10th is 16 hours out of 24

so 16/24 = ⅔

his hash is 10/15 = ⅔

it looks perfectly normal to me.

I would prefer to see his pool stats.

I think he rebooted and gets a 16 hour read if you look you can see he is at 16 hours and change.

sometimes braiins reboots on its own and starts the clock again

Hello All

I am using BraiinOS+ and I am seeing what I assume to be a very high rejection ratio. I did notice that my estimated daily reward dropped then what it has normally been.
