i saw this and wondered - is the efficiency accurate? it claims 20J/T

Yeap you can check on github: https://github.com/skot/bitaxe/tree/ultra?tab=readme-ov-file#bm1366

BM1366

   -The BM1366 is a undocumented SHA256 mining ASIC from Bitmain. It's mostly used in the Antminer S19XP
-Bitmain claims the BM1366 has 0.021J/GH efficiency
   -The BM1366 is available (new) for around $15 each in small quantities.
   -The BM1366 has a different footprint and pinout from the BM1397 and BM1387 in previous bitaxe.
   -The BM1366 appears to roll more than just the nonce on the chip. This is great news, because it allows much longer serial chains of ASICs and new work doesn't need to be sent as often.

have you found or tried a way to exceed 570mhz?

I found a solution and it seems to work

At the moment I have no problem with the 2.07 firmware.
Reverting back is possible with the normal website from the miner? Or do you flash the miner per USB?
Just interested to be prepared if I have also step back to a older firmware.

Best regards,
Willi

Yes you can revert back from miners UI / Website.

For me V2.0.4 seems to be more stable.

You guys make sure to report an issue here:
https://github.com/skot/ESP-Miner/issues

It's much more likely for the maintainers of the firmware to see it there.
Do include as many details as you can (e.g. after how much time exactly something happens, what happens, ...) to help them get it fixed.

Submitted the bug and added an enhancement request to add suggest difficulty to the UI to help expedite the miner finding its sweet spot on pools.

I'm reverting back to the V2.0.4 firmware.

I updated one of them to V2.0.7 and was getting reboots every 4-10 hours.

Stock settings so lets see if this is a firmware or hardware issue.

Got the same issues that Sledge is reporting.
Cannot address the exact problem but getting reboots in the same time frame or the hashrate is decreasing to 0TH/s and is stuck until I do a manual reboot.

Will flash back to an older version and will monitor it.

Hi
Has anyone tried using a voltage value of 1300mv for a few months? could it be exaggerated or dangerous for a long time? Thank you

I don't own the BitaxeUltra, but having worked with similar chips on stick and pod miners in the past, it's generally safe to run any voltage, as long as the chips stay cool enough.
In some cases, industrial miners run their chips at substantially higher voltages than the ranges we use on micro-miners, even when using the exact same chips, simply because they have better cooling solutions like high-flow, high-pressure - but very loud - industrial fans, or liquid cooling setups.

Do keep in mind that there's a point where your efficiency starts to decrease, simply because the increased power draw from the higher voltage stops yielding substantial improvements in stable clock speed (and thus maximum hashpower), so keep an eye on that as well.

this new bitaxe web flasher supports all bitaxe models: https://wantclue.github.io/bitaxe-web-flasher/
this tool is designed to flash your bitaxe with the latest version of axeos, ensuring you have the most up-to-date features and improvements for your device.

https://github.com/WantClue/bitaxe-web-flasher

Not sure you wouldn't go right from the source but to each their own...

In any event V 2.0.7 of the firmware is out with a few fixes!

For those BitAxe Ultra users there is a new firmware V2.0.6 out for the device!

https://github.com/skot/ESP-Miner/releases

If you want to retain your settings then update the following 2 files named (esp-miner.bin & www.bin) each is listed under v2.0.6.

feedback: please make a ethernet vesion. Due to privacy and security issues, i dont use wifi. Hope the bitaxe HEX makes it or atleast has a USB Type C so one can use a ethernet to type C adapter.

The ESP32-S3 we use in the bitaxe does not have a Ethernet MAC, so this is not an easy change. What sort of privacy and security issues do you have with WiFi?

Great project, inline with the Bitcoin spirit! Skot, did you try to use a PWM pin connected to an RC filter, can even be two stages of RC filtering, to get rid of the DAC IC? Let me know if I can help.

I dont like wifi due to health issues, You can atleast have a V2 or USB type C so that users can buy their own ethernet to usb type c adapter.

Health issues? Due to electromagnetic radiation? Because you're exposed to that 24/7 no matter if you turn off your WiFi or not. Think: HF radio, amateur radio, cellular radio, police radio, other people's WiFi networks, and the list goes on. Walk around your home with a software defined radio and check out how much is going on across the whole frequency range.. Tongue

I can understand that, and I am thinking the same way.
There is a development kit for the esp with phy but you have still the firmware and tcp stack from the vendor, with all the "goodies".

Anyway, there is a fork of the bitaxeultra named Pi-axe.
I pointed that allready out here in the german section:
https://bitcointalksearch.org/topic/m.63279811

The design is as a "hat" for the Raspberry-Pi and you use the Pi Network, LAN or WiFi for comunication and it runs under a normal Linux.
The User Mampf of the electronic forum mikrocontroller.net has made this as a hat for the Raspberry-Pi and provided the files for it in github:

Pi-axe Hardware:
https://github.com/shufps/piaxe
Miner software in python for the Raspberry-Pi:
https://github.com/shufps/piaxe

The original thread is in german, but you can of corse write in english there:

how long now for one with the new s21 chips? wouldnt that be easy to implement given s19 xp chip experience?

i would love a 6 chip one Grin

You’ll need Linux and host mode USB for that to work — both a long shot for the ESP32. I think there is another ESP32 variant that has an Ethernet MAC, so that would be an easier place to start. There is a company called Olimex that make some ESP32 Ethernet dev boards (PoE too, I think). That would be a reasonable place to start.

PoE+ miners would be insane! :~)
