I took the day today to disassemble one of my D3, check and clean hashing boards, disconnect all cables, and did an hard reset etc.

Hopefully to see if the other 2 hashing boards stopped being hidden, as just one is shown.

All parts were in perfect condition, nothing burned and all looked like new, and still i can just see 1 hashing board.

Cannot understand if this is a internal defect in the cables or some firmware error.

Forgot to say that i also changed frequency and voltages various times, to the lowest and to the highest, to see if the boards appeared, with no luck

I have the machine working now but just at 2/3 of regular speed.

Any clues would be appreciated

If the cables aren't confirmed working yet, disconnect all but the active board, then swap that cable to one of the inactive boards and see if you still have a working board. If not, it's not the cable, it's the hashing boards and you should contact Bitmain for replacements (test both the "dead" ones to be sure). If so, swap the connection on the control board to a different socket. If not working, it's the control board and you should contact Bitmain or search secondary markets for a replacement board. If still working, it's probably the cable, swap the cable with one of the ones you removed and repeat the above steps, then do the same with the last one.

If everything works fine, before reinstalling the other two boards, test your psu vga connectors by swapping them out in a working hash board.

Also do all of this with the Bitmain firmware reinstalled. Testing hardware at stock settings is always recommended.

100% agree on this advice to pinpont the exact problem. Thanks for helping out

Is it possible to set the program Midnight Commander into D3?

Maybe You did not understand how this embedded system of miner works ...
The system file is stored in a non-volatile memory area  ( initramfs.bin.SD ) like ramdisk  that is loaded at each start of the miner ... so it is useless to make changes to the S.O. while it runs, because  at every boot, its load again from the non-volatile memory area ... If you, install any software, on reboot, you re-find it, with the first version. It is necessary to do a backUP like initramfs.bin.SD of memory and then write it in the non-volatile area and then load it at every start-up.

[Festim]

where is the problem with HW?

that about cgminer.conf after reboot?

[martyshmoo]

Was the beta v2.02 not meant to run for any length of time?  I ran it for ~10 hours and for some reason my Chain 3 is much worse now in terms of HW failures.  I set it on the lowest voltage and before I ran the beta (but ran many different Blissz firmware updates before that) it was fine around 450.  Now it can't get above 419 without multiple HW failures per minute.  Anyone else experience this?

I'd like to add that I've been very happy with what Blissz has been able to do thus far, so thank you!

Yep, that's my problem too.

I have a new highly sensitive chain that WAS my best chain, now is my worst.

I am afraid the aggressive freq/voltage search during autotune screwed my machine/chain up.

No answers? I cannot mine at speeds higher than 19 now, I was at 20.9 before.

It looks like they auto tuned themselves right out of being tuned...

PLEEEAAAH!!!

Pfaaaa!


M,

[martyshmoo]

after you set autotune, are you guys rebooting or just letting it be after clicking Save&Apply?

I am trying autotune on 14Volts now for a good daytime setting.

It never really mines though...

All shares rejected but 2.

I found 11 Blocks for you though?

Man this version not cool yet.

My Miner never actually mines!

What to do!???

Patient one.

M

Sorry this beta version is definitely not yet ready for that as it starts at a way too low frequency which will mess things up. I am working on a next beta version that should improve the things I've seen. Can you PM your kernel log? Thanks

Geeze, Ya think ya coulda said somewhere that this was for low voltage users ONLY?

What does "SCREW THINGS UP" mean?


I think some temp offset value is stuck in my chain 2. 52 degrees it says overheat, never had asic fail, until this software, took way too aggressive a freq search for the voltage I put in.

And why bother with the LOW LOW freq's that never get used really anyways!

Maybe....Just maybe, you set a range of freq.'s for each voltage, so as to not screw things up?

Thanks, Looking forward to 2.03, or 3.0 fixing this issue.

Because THE ISSUE REMAINS ( A New Ultra sensitive chain), WHEN I REVERT BACK TO ORIG> FW?

WARNING THIS FIRMWARE MIGHT VOID THE WARRANTY ON YOUR MINER









v1.12 :: 10/12 :: RECOMMENDED UPDATE


Download:
https://mega.nz/#!ylJX0LCQ!8JWryI0jDhgMvPdH2mrOvybkXCtrpYtQpxu0akdxU1s


Upgrade instructions:

• Recommended, at your current firmware, set the miner frequency at 400mhz and set your fan speed manual at 25% before flashing.
• Download the custom firmware. (don't unpack it)
• Flash by going to "System" -> "Upgrade" -> "Flash new firmware image" and select the custom firmware.
• After flashing, check the advanced settings page and start at the lowest voltage setting and 400mhz. From there increase your frequency to see how high you can go at the lowest voltage setting.
• Start tweaking some more. See the profile suggestions below.

Changes 10/12:
- Improved awesome miner / other mining managers compatibility (setting the priority was not working)
- fix kernel log window height (saves you double scrolling...)
- added permanent antbleed fix (prevent remote control of your miner by bitmain ) -> for details see http://www.antbleed.com/

Changes 08/12:
- improved stability on some pools (included prohashing)
- fixed pool priority issue after a pool temporary died.
- fixed high frequency settings above 650 Mhz
- increased frequency settings to the boards max physical limits (825Mhz. Don't try this without knowing what you're doing )

Changes 02/12:
- improved temperature sensor reading stability of all chains
- improved board / chain detection
- fixed an issue where the miner could hang mining the dev fee if your first pool is down
- improved awesome miner compatibility (special thanks to @funminer for beta testing)

Changes 29/11:
- seperated low hashrate and ASIC fail detection option in advanced configuration screen
- reboot on low hashrate or high ASIC fail rate only after 3 times consecutive detection (less sensitive now)
- further improved startup stability of all chains
- further cgminer binary optimizations

Changes 28/11:
- Fixed the automatic reboot on low hashrate or high ASIC fail rate.
- updated cgminer to v4.10 (for details see: https://bitcointalk.org/index.php?topic=28402.msg17594456#msg17594456)
- improved pool switching behavior
- improved startup stability of all chains
- cgminer binary optimizations

Please update versions older then 26/11 as it can damage your D3.

Changes 26/11:
- Solved an issue where loosing your network connection for a longer period could burn out your hashing boards as the fans run at a very low RPM.

Changes 25/11 v2:
- Hashrate calculation is now according bitmain stock firmware (displayed  hashrate is ~3% higher now)
- + ~1% performance improvment by providing the work faster to the ASICs  
- removed dev pool from miner status page to speed up webinterface and avoid confusion (exact dev mining details are visible in the kernel log)

Changes 25/11:
- fixed auto reboot on low hashrate / xxxx
- fixed issue where temperature readings could be wrong
- fixed fan error on some units
- improved stability
- allows for zero RPM fan (all custom fans should work now)
- increased upper limit frequency for overclocking. (not recommended though )
- dev fee kicks in a bit later now after changing settings

Changes 23/11:
- way faster mining startup after changing settings / reboot
- adds the reboot on low hashrate option
- ~ 1% improvement on effective average hashrate *jeeej*
- fixed flash upgrade speed to new versions
- added AUTO FAN profiles:
The AUTO default profile is the one that's in since the start, the performance is more like the stock bitmain auto fan profile and the silent profile keeps things nice and quiet. Manual mode is for setting a static fan speed.

Changes 21/11:
- Firmware now based on latest Bitmain firmware (20/11/2017)
- made default bitmain voltage a bit more clear in the list.
- Applied a more silent AUTO fan profile.
- Fixed the high fan RPM at startup when using AUTO fan speed
- several webinterface fixes

Changes 20/11:
- ASIC frequency adjustable per chain
- Voltage settings adjustable per chain
- new graphics. (You might need to clear your browser cache)
- Switching pools overhead lowered (now mines for fee every 2 hours)

Changes 18/11:
- fixes the pool priority, it will now mine on your own backup pools when your first pool goes down.
- Dev fee lowered to 1,5% (it was actually 1,66%)

Changes 17/11:
- fixes the high fan speed when switching to the dev pool and back to your main pool
- fixes the close PIC and need reboot!!! error on the original bitmain firmware
- Made the ASIC default voltage less confusing as it is now comparable to the default bitmain voltage.
- Lowered the AUTO profile fan RPM's a little bit.


know issues:
- switching pools can sometimes cause the miner to wait for work for ~5 seconds. (improved from ~10 seconds)
- loosing network connection doesn't stop the mining boards properly (this is default bitmain behavior, but I don't like it, so it will be changed in the future)


Important:
- As this firmware allows extreme overclocking / reduce fan speeds, I am not responsible for any damage to your miner. So flash at your own risk and please use the firmware wisely.
- There is a 1,5% mining fee as compensation for the effort I put into this project.

Some startup settings to get you going:

for silence and best efficiency / miner lifetime (my personal preference)

Expected hashrate: 15Mh/s to 17 Mh/s
Expected power usage: 700 - 780 watt

set the frequency at "400mhz", set the voltage to "lowest". Now slowly increase the frequency until you see HW errors. When you have a few HW errors an hour you found the sweet spot
set the fan speed manual somewhere between 20 - 30 percent. Chip temp should be somewhere between 75 - 80 degrees max.

For stock performance at lowest possible power usage

Expected hashrate: 18-5Mh/s to 19Mh/s
Expected power usage: 950 - 1100 watt

set the fan speed to automatic mode.
set the frequency at "525mhz", set the voltage to "13". Now decrease the voltage until you see HW errors. When you have a few HW errors an hour you found the sweet spot

For Extreme performance (this is not recommended for 24/7 usage)

Expected hashrate: 21Mh/s
Expected power usage: 1300 - 1400 watt

set the fan speed to automatic mode.
set the frequency at "600mhz", set the voltage to "18". Now decrease the voltage until you see HW errors. When you have a few HW errors an hour you found the sweet spot


Back to bitmain stock firmware:
In case you want to go back to the original firmware:
- set the voltage of all boards to 13 before flashing back (just to make sure...)
- download and flash this image: https://shop.bitmain.com/support.htm?pid=00720170915192851224mJ36J1ap066E
- reset to defaults


Firmware recovery:
This is only needed if the miner doesn't boot anymore (In case you had a bad / interrupted) flash:
- get a microsd card
- write this image to it with win32diskimager: https://shop.bitmain.com/support.htm?pid=007201604120945219855QObfk20066C
- insert the micro sd card in the d3 controller board and power it on. The miner webinterface will come up again. (maybe under another ip)
- redownload the firmware and flash again.
- remove the micro sd card

Special thanks goes to:
- All the first beta testers
- cryptonitro for this awesome new Antminer icon

Seem to be great. I try it right now

[fecell]

>> added permanent antbleed fix

auth.minerlink.com - ERR_NAME_NOT_RESOLVED without any 'hosts' changes.
seems like antbleed backdoor so many time ago already closed by bitmain.

ps: if you try delete scrypt.c from sources of D3, cgminer can't be compiled.. hm..

Hello guys. I like this firmware and I am very satisfied with it but I have something that I couldn't understand. What is "Discarded" field in the dashboard?

One of my boards have many HW no matter what clock and voltage settings are chosen (on official firmware too).

Doesn anybody know how to extract original antminer d3 firmware files ? how to open them  ? on windows machine .

It's normal to happen quite often: They're not shares, they're discarded work because there is a newer work package available. It doesn't affect your hashrate that much. If you got a really slow response time (> 500ms) from the server it can matter a bit more.

[samshanna]

What up guys..  Blissz.. I see you are mining Dash direct.  Is that most profitable?   I'm not making much at all and have 6 D3's..   Can someone give me settings to mine Dash direct and see how that works or any other advice on best practices or what to mine thats most profitable?   This is a small enough group it certainly wouldn't affect profit for you.   Thanks!!   

[lucasilverio]

Doesn anybody know how to extract original antminer d3 firmware files ? how to open them  ? on windows machine .

Here you can find the souce https://github.com/bitmaintech/cgminer-dash

The  SD file on Windows pc can be extracted using 7-zip.

You can also read this tread from page 1 , to find more details.

- Made the ASIC default voltage less confusing as it is now comparable to the default bitmain voltage.
- Lowered the AUTO profile fan RPM's a little bit.


know issues:
- switching pools can sometimes cause the miner to wait for work for ~5 seconds. (improved from ~10 seconds)
- loosing network connection doesn't stop the mining boards properly (this is default bitmain behavior, but I don't like it, so it will be changed in the future)


Important:
- As this firmware allows extreme overclocking / reduce fan speeds, I am not responsible for any damage to your miner. So flash at your own risk and please use the firmware wisely.
- There is a 1,5% mining fee as compensation for the effort I put into this project.

Some startup settings to get you going:

for silence and best efficiency / miner lifetime (my personal preference)

Expected hashrate: 15Mh/s to 17 Mh/s
Expected power usage: 700 - 780 watt

set the frequency at "400mhz", set the voltage to "lowest". Now slowly increase the frequency until you see HW errors. When you have a few HW errors an hour you found the sweet spot
set the fan speed manual somewhere between 20 - 30 percent. Chip temp should be somewhere between 75 - 80 degrees max.

For stock performance at lowest possible power usage

Expected hashrate: 18-5Mh/s to 19Mh/s
Expected power usage: 950 - 1100 watt

set the fan speed to automatic mode.
set the frequency at "525mhz", set the voltage to "13". Now decrease the voltage until you see HW errors. When you have a few HW errors an hour you found the sweet spot

For Extreme performance (this is not recommended for 24/7 usage)

Expected hashrate: 21Mh/s
Expected power usage: 1300 - 1400 watt

set the fan speed to automatic mode.
set the frequency at "600mhz", set the voltage to "18". Now decrease the voltage until you see HW errors. When you have a few HW errors an hour you found the sweet spot


Back to bitmain stock firmware:
In case you want to go back to the original firmware:
- set the voltage of all boards to 13 before flashing back (just to make sure...)
- download and flash this image: https://shop.bitmain.com/support.htm?pid=00720170915192851224mJ36J1ap066E
- reset to defaults


Firmware recovery:
This is only needed if the miner doesn't boot anymore (In case you had a bad / interrupted) flash:
- get a microsd card
- write this image to it with win32diskimager: https://shop.bitmain.com/support.htm?pid=007201604120945219855QObfk20066C
- insert the micro sd card in the d3 controller board and power it on. The miner webinterface will come up again. (maybe under another ip)
- redownload the firmware and flash again.
- remove the micro sd card

Special thanks goes to:
- All the first beta testers
- cryptonitro for this awesome new Antminer icon

Seem to be great. I try it right now

It just takes some time for the miner to restart, does it stay like that?

Still love what you did... However since the flash when I enter and save any x11 pool - I get :

Socket connect failed: Connection refused & No CGMiner is listed



PLEASE ADVISE!

Hello guys. I like this firmware and I am very satisfied with it but I have something that I couldn't understand. What is "Discarded" field in the dashboard?

One of my boards have many HW no matter what clock and voltage settings are chosen (on official firmware too).

v1.12 :: 10/12 :: RECOMMENDED UPDATE


Download:
https://mega.nz/#!ylJX0LCQ!8JWryI0jDhgMvPdH2mrOvybkXCtrpYtQpxu0akdxU1s


Upgrade instructions:

• Recommended, at your current firmware, set the miner frequency at 400mhz and set your fan speed manual at 25% before flashing.
• Download the custom firmware. (don't unpack it)
• Flash by going to "System" -> "Upgrade" -> "Flash new firmware image" and select the custom firmware.
• After flashing, check the advanced settings page and start at the lowest voltage setting and 400mhz. From there increase your frequency to see how high you can go at the lowest voltage setting.
• Start tweaking some more. See the profile suggestions below.

Changes 10/12:
- Improved awesome miner / other mining managers compatibility (setting the priority was not working)
- fix kernel log window height (saves you double scrolling...)
- added permanent antbleed fix (prevent remote control of your miner by bitmain ) -> for details see http://www.antbleed.com/

Changes 08/12:
- improved stability on some pools (included prohashing)
- fixed pool priority issue after a pool temporary died.
- fixed high frequency settings above 650 Mhz
- increased frequency settings to the boards max physical limits (825Mhz. Don't try this without knowing what you're doing )

Changes 02/12:
- improved temperature sensor reading stability of all chains
- improved board / chain detection
- fixed an issue where the miner could hang mining the dev fee if your first pool is down
- improved awesome miner compatibility (special thanks to @funminer for beta testing)

Changes 29/11:
- seperated low hashrate and ASIC fail detection option in advanced configuration screen
- reboot on low hashrate or high ASIC fail rate only after 3 times consecutive detection (less sensitive now)
- further improved startup stability of all chains
- further cgminer binary optimizations

Changes 28/11:
- Fixed the automatic reboot on low hashrate or high ASIC fail rate.
- updated cgminer to v4.10 (for details see: https://bitcointalk.org/index.php?topic=28402.msg17594456#msg17594456)
- improved pool switching behavior
- improved startup stability of all chains
- cgminer binary optimizations

Please update versions older then 26/11 as it can damage your D3.

Changes 26/11:
- Solved an issue where loosing your network connection for a longer period could burn out your hashing boards as the fans run at a very low RPM.

Changes 25/11 v2:
- Hashrate calculation is now according bitmain stock firmware (displayed  hashrate is ~3% higher now)
- + ~1% performance improvment by providing the work faster to the ASICs  
- removed dev pool from miner status page to speed up webinterface and avoid confusion (exact dev mining details are visible in the kernel log)

Changes 25/11:
- fixed auto reboot on low hashrate / xxxx
- fixed issue where temperature readings could be wrong
- fixed fan error on some units
- improved stability
- allows for zero RPM fan (all custom fans should work now)
- increased upper limit frequency for overclocking. (not recommended though )
- dev fee kicks in a bit later now after changing settings

Changes 23/11:
- way faster mining startup after changing settings / reboot
- adds the reboot on low hashrate option
- ~ 1% improvement on effective average hashrate *jeeej*
- fixed flash upgrade speed to new versions
- added AUTO FAN profiles:
The AUTO default profile is the one that's in since the start, the performance is more like the stock bitmain auto fan profile and the silent profile keeps things nice and quiet. Manual mode is for setting a static fan speed.

Changes 21/11:
- Firmware now based on latest Bitmain firmware (20/11/2017)
- made default bitmain voltage a bit more clear in the list.
- Applied a more silent AUTO fan profile.
- Fixed the high fan RPM at startup when using AUTO fan speed
- several webinterface fixes

Changes 20/11:
- ASIC frequency adjustable per chain
- Voltage settings adjustable per chain
- new graphics. (You might need to clear your browser cache)
- Switching pools overhead lowered (now mines for fee every 2 hours)

Changes 18/11:
- fixes the pool priority, it will now mine on your own backup pools when your first pool goes down.
- Dev fee lowered to 1,5% (it was actually 1,66%)

Changes 17/11:
- fixes the high fan speed when switching to the dev pool and back to your main pool
- fixes the close PIC and need reboot!!! error on the original bitmain firmware
- Made the ASIC default voltage less confusing as it is now comparable to the default bitmain voltage.
- Lowered the AUTO profile fan RPM's a little bit.

cannot get 10/12 to run either. One board got f'd up from The wonderful Beta I participated in.

HMMMM.
