Braiins OS & Braiins OS+ custom ASIC firmware: optimize performance & efficiency

[minefarmbuy]

I don't see any or much difference in performance from the LPM firmware bitmain released.

bOS lets you control voltages/freq/fans on a board by board basis, don't think you can do that with BM's FW.

[minefarmbuy]

What are your settings/results?

[Dangles89]

For the fan speed, what is everyone setting their desired temp to?

[minefarmbuy]

I'm running auto control right now, I noticed the s9 13.5th unit I have which had "intermittent" fan spin up is gone since today.

Here are some tests I have done with different frequency and voltage on S9J, 14.5 TH/s
Have not get time to check power draw yet, will do soon and add them too.

As you can see some miners give different hashrate with same settings,
So your experience may differ.

If you want to aim for efficiency, you might want to try 500 mhz 8.0~8.1volts.
The goal for efficiency is achieving the highest hash rate a single watt can give, even if you end with miners doing 10TH/s but consuming 823watts.

Philipma1957 managed to obtain impressive results, you might want to find out which setting is the most efficient, but as you said, each board behaves differently.

S9s used to spend 100 watts per TH, but now with Braiins OS they can do 80. Under-clocking should not be underestimated...

Agree.
My ampere meter broke the other day so I will run more tests based on efficiency as soon as I fix it or get a new one.

have you checked the HW errors too?

[papampi]

Updated table
Included HW Error Rates from antminer monitor

When I started testing I set some miners to 775 MHz with 8.7 V and got too many HW errors
So I excluded them from further tests and did not set any over 750 MHz,  8.7 V

But I see each miner shows different behaviors with different freq and volts, so everyone should use their own observations and dont rely on these values

I fixed the duplicated MAC address, work great now. But I still wonder why bOS is spoofing the MAC address

I clocked my S9i to 375Mhz / 8.1volts   this give me 8TH at 750w with EVGA G2 1300W / 120Vac.
Best part is fan are running at 10%, quieter than an R4.
Fan control have improve a lot from previous version.
I switched from APW3++ P/S to EVGA because is quieter.
The APW3++ was making more noise than the S9  

I didn't try to disable ASIC BOOST to verify from last version, next thing on my list when spare time is available.

Great software !

[papampi]

I think there may be some improvements can be done in the next release.

1- All miners showing an upgrade icon after a day of running even though they are on latest.
Tried the web-ui upgrade button, it asks to install firmware then prints: "Package firmware (2019-01-24-0-d3cc7c87) installed in root is up to date."
Tried opkg update with same result
The upgrade button is always there.

2- AsicBosst column only shows a hyphen "-"
Tested on slushpool, antpool and btc.com, all shows just a hyphen.
Does this work for anyone else?

3- Would be nice to have auto refresh toggle in miner status page too.

this is only a display bug, AB is enabled. It will be fixed in the next update

[Artemis3]

Does it have the SD slot? If not, you can't use it.
That error simply means 256M of ram is not supported, maybe it needs 512M?

Good news for ollehto, this was just written in the telegram group:

So, the G29 boards for T1's do have only one DDR module = 256MB of RAM instead of 512MB as in case of G19. We have adjusted the SPL (first stage bootloader before u-boot) to work with G29. It shows a lot of manufacturer competence claiming the boards G29 are the same as G19... Anyways, TLDR -> next update will support G29 based dragon mint miners

So wait for the next version and your board might be supported!

Looks fine to me.

Awesome job with this release!!

A couple things on S9:

1) Miner Status just states:
     "Miner Status: Gh/s 1m"
     Is this supposed to have a realtime hashrate number displayed??

2) Will you please consider adding Best Share found? While useless, it's interesting and something I like to check periodically?

Thanks!

[Artemis3]

Confusing as it may look, this probably just means a unit of measure. As in: number of Giga-hashes per second in 1 minute (the numbers inside the graph, at the left).

The real time measurement is in the small numbers at the table below: Real rate, Chip Rate.

Perhaps this is meant to indicate the refresh rate on the graphic, so it could be perhaps changed to 15m or 24h stats instead? (or planned to).

[philipma1957]

On the other hand...

If you, like me, only have one or a few miners and can afford the electric bill without selling off your mined btc, you will have more btc to sell later when price goes up (if it ever goes up)...

This is  a very well written analysis  thanks.

How do I downgrade to BOS 2018-11-27 from 2019-01-24 on S9? I found

Code:

python3 bos2bos.py transitional-firmware-url your-miner-hostname-or-ip

but 2018-11-27 is no longer available on https://feeds.braiins-os.org/

With latest firmware one of my miners is restarting due to high temperature (was working correctly before update).
