I could see things not getting updated being a sd card issue, if the pattern of LEDs is the same on the dead board as the others then you don't have a blown chip, normally there drastically different or not at all, you said green/red LEDs so I am guessing the boards are green, check cables , swap two of them and see if the dead board moves or stays the same, if it moves then maybe a bad cable if the same then might be a messed up board, most trouble shooting steps at this point are very advanced, requires probing stuff and such. I don't know if I would buy a new board really the cost vs/ the payback is going to be a bit off .

Ok, so after some troubleshooting with no luck, I decided to let it be for a few days. Suddenly tonight I had another board basically die. This has to be a power supply issue, right? Should I try switching out the 6+2 pin PCI cables? Or switching around where they're plugged in? PSU is fully modular, so I have a few open plugs to try, but I'd imagine if one part of the power rail fails, it all does... I'm starting to get really worried that I dropped over $900 on a rig that is just falling apart, and then another $280 for a PSU that I got no reimbursement for from Zoomhash, but I'm holding out hope that it's just the PSU. Is there a way I can test the output of the PSU? Having 2 boards die off of a 1300W gold rated output shouldn't happen. Hoping for a very fast response before I throw this thing off of a cliff.

your case sound very similar to mine.

My A2 had 5 boards, one by one the boards failed, and now I only have 2 boards working.
I have turned off the A2 - 110mh before 44mh now = waste of electricity.
I wrote to Innosilicon and they dont do returns...
But online sellers in Aliexpress selling 136$ per board - see my earlier post

Can your lasting 2 boards be installed into an 88Mh setup with the 8 chip boards? If so, what do you want for the 2 that are working?

I am not sure if can be refitted into a 88MH machine.... technically I dont think any issues... this A2 came with 5 board for 110MH.
One of nerd friends is working on the A2 now and I hope he could make it work again - so I will hang on to it for little longer.

Waiting for my coins to rise !!

Is there a idiots guide to solo mining anywhere. the more i read the more confused i get. I did a conf file for devilcoin DXC just to play about with..
server=1
listen=1
daemon=1
rpcuser=james
rpcpassword=x
rpcallowip=127.0.0.1
rpcport=6624
addnode=162.243.239.239
addnode=77.99.98.229
addnode=86.5.28.9
addnode=82.144.204.28
addnode=104.238.156.251
addnode=151.80.42.180
addnode=70.72.236.5

saved it as a .conf file and added it to devilcoin dir and then restarted the wallet.

In my A2 software POOL 1 ADDR i put http://127.0.0.1:6624 then james as user and x in password

When i run the software it says the pool is dead and moves onto POOL ADD 2 and works

Is my config file wrong ? is the POOL 1 ADDR wrong ?

Any help much appreciated.

I've got 7 - A2's. Had a couple from when they first shipped and got 4 more when pricing on scrypt devices was at bottom.
Almost all of them have required some maintenance, but I've only had 1 hashboard fail completely. I think it burned from heat overload as there was a fan that died on it and the hashboard was relatively loose from the chassis - so little heat was being exchanged to the chassis. I've done a fair amount of tweaking/soldering/ etc to keep these operational. One HUGE point of weakness is the soldering points of the PCI power connectors to the board. I'd say 1 out of 4 have lost full conductivity - mostly at the soldering joint of pin to the board, poor conductivity of power leads to intermittent drops of the board.

Since you swapped out your PSU, that means you've had to disconnect and reconnect these - and good chance that one or two may have integrity loss of connection.

Sometimes boards can benefit from removal and reinsertion of the data cables as well. Which is another weak point on these boards. I've literally pulled some of the L shaped pins out of the soldering points on the board, or broken pins off. Be extremely careful when removing the cables - again if you have a pin that has a poor connection it may result in hashboard just blinking and never synchronizing - much the same as a bad power connection.

If the problem is either the PCI connection pins or the data cable connection pins - it can be fixed. I've actually had a unit fall 4 feet from a shelf and broke off 2 of the PCI pin connectors from the board, breaking the PCI board in the corner. There is an additional 6 pin power connection on the board as well - underneath the 8 pin. I've used this second set of connections on the board and soldered some 6 pin connections to them and got the boards working. With the boards that have had broken pins on the data cable, I either resoldered those pins back to the board or stripped the 10 pin data cables and soldered the wires directly to the board. In all cases the boards have worked again. Only the one instance of the suspected burnt chip on one board have I not been able to resurrect.

A good way to start troubleshooting is disconnect all datacables (I suggest at the controller board instead of each individual hashboard - to avoid pin stress on the hashboard). Leave the one board you want to troubleshoot plugged in - disconnect all power to hashboards except to that single board as well. This reduces the chance that another board is interfering with the function of the one being tested. In some cases one failed power connection could result in all the connected boards to fail synchronization.

You could also remove the heatsink and look visually at the chips to see if any appear burned.

Has anyone got board replacement from Innosilicon?
What's the procedure for board replacement?
Confirmed, my A2 110MH, 3 boards now not responding after many troubleshooting, i think best if just get replacement board.
Can the boards be purchase etc. assuming no warranty? Mine is less than 6 months old.

I have done some legwork on replacement boards for my A2-110MH and below the disappointing results...

1. Sent email to Innosilicon in China about getting me a replacement board, the reply as follows:

1st email:
"....We have board replacement, unfortunately they are not available for sale since it’s easy for separate boards to get broken during internal shipping..."

Best regards,
Chloe Zhang / [email protected]

2nd email on trade-in programs A2 to A4:
"...Sorry we don’t have such program, but we will offer A2 buyers we have on record some discount on A4 miners...."

2. Sent email to online-seller in China, the guy I bought the A2-110MH from... he sympathized with my situation however he offered board replacement. Its about 136$USD per baord but excludes shipping... in which for me was same price as the board.... to replace 3 boards.... I might as well buy a new A2-110MH.... anyways, seller reckons that the A2 could still be saved, and not worth going to A4 now because he is still waiting for the announcement from Innosilicon and price is unknown at this time.

You might try zoomhash, I contacted them a while back and they said $85, think they were the green boards. I never did buy any

Thanks for the tip, mxnsch. I'll definitely look into tweaking some of the values in the future. I did figure out what the problem was, though. Turns out the outlet I had the miner plugged into died, but not completely. Once I turned the miner off and unplugged it, I tested the outlet with a multimeter. The output was, and currently still is, 15VAC. Something that's also a bit more troubling, all other outlets in half of my house are now over-volting, including ones on the same circuit as the dead outlet. All are reading between 155-165VAC, which I know is a dangerous thing when it comes to sensitive electronics. They also have a higher amperage than my multimeter can read, which has a cap of 20A. I'm 99% certain that the miner did NOT cause this problem, but rather was the first thing to be 'punished' by the problem.

But with the good news comes bad news... Plugged the miner back into a stable circuit, turned it on, and cs3 (Board #4) is dead. Board 4 is the one that hit 101*C, which I would imagine any piece of equipment hitting the boiling point means the kiss of death. I'm planning on opening up the rig tomorrow to see if there's any visual damage, as well as reconnecting all of the cables. Will also reflash the SD card just in case. But, as it stands right now, the board is dead as far as I can tell. It always ran hot to begin with, averaging close to 6*C hotter than the other 5 boards, even with super cold winter air. Probably little to no thermal paste on there is my theory...

Last little question, but does anyone know if replacement boards are sold anywhere? Or if anyone, most likely someone on this forum, offers repairs? I don't know the specifics of the multiple ways heat can damage a board, so I'm not sure if it's repairable. Poor old rig has been mine for less than 3 months and this happens lol

Anyways, thanks for your help guys. I'll check back in a few days if I find out anything interesting.

Well at least you got some answers, as for bad boards normally they will blow a chip and then it is done, they cant communicate anymore , I have fixed a few but most of the time it takes more than one chip. As far as thermal paste there problems with all the ones I worked on I tore them all down for some unknown reason on the bottom there was thermal paste on a thermal pad which is worse , I put paste on the bottoms of the board under the chips and on top of them helped a lot with temps and just got rid of the pads all together.

I think you can get replacement boards from zoomhash they were like $85 when I contacted them which means like a bit of time to pay it off. I wouldnt bother with a reflash, are the LEDs different on the dead board?

mjgraham, initially the board had no LEDs at all, but starting today the board 'woke up' and now shows signs of life. The 5 working boards all have solid green/red lights while hashing, and the dead board just continues to flash the LEDs. It's almost as if the Pi isn't recognizing it, or it could be to what you mentioned where once the board blows a chip, it just stops communicating.

I had a theory that perhaps the board might not be receiving sufficient power. When the problem first started, I received this message for all 6 boards, which were all "on" but being powered by the dead power outlet:

After fixing the power problem, 5 boards work, but board #4 (cs3) still gives that exact message. I'm also starting to think that I should reflash the SD because ever since the problem started a week ago, the graphs on the main page refuse to repopulate. All 8 graphs show Saturday (March 26) at 6:00 PM to Sunday at 6:00 PM, right when the temperatures hit 100*C. This is also the case for the 'Historical Statistics', 'Logs - Messages', and 'Logs - Syslog' pages. In my eyes, I see 3 variables that could be the problem: corrupted SD, corrupted Pi/ribbon cable to cs3, or a dead board altogether. However, if the board is dead, that doesn't explain the non-responsiveness of the logging system. Thanks again mjgraham.

But, as it stands right now, the board is dead as far as I can tell. It always ran hot to begin with, averaging close to 6*C hotter than the other 5 boards, even with super cold winter air. Probably little to no thermal paste on there is my theory...

Last little question, but does anyone know if replacement boards are sold anywhere? Or if anyone, most likely someone on this forum, offers repairs? I don't know the specifics of the multiple ways heat can damage a board, so I'm not sure if it's repairable. Poor old rig has been mine for less than 3 months and this happens lol

Anyways, thanks for your help guys. I'll check back in a few days if I find out anything interesting.

Well at least you got some answers, as for bad boards normally they will blow a chip and then it is done, they cant communicate anymore , I have fixed a few but most of the time it takes more than one chip. As far as thermal paste there problems with all the ones I worked on I tore them all down for some unknown reason on the bottom there was thermal paste on a thermal pad which is worse , I put paste on the bottoms of the board under the chips and on top of them helped a lot with temps and just got rid of the pads all together.

I think you can get replacement boards from zoomhash they were like $85 when I contacted them which means like a bit of time to pay it off. I wouldnt bother with a reflash, are the LEDs different on the dead board?

A4 has not been released yet.

In theory, it COULD be released literally any day now - but no word out of Innosilicon recently.

Thanks for the tip, mxnsch. I'll definitely look into tweaking some of the values in the future. I did figure out what the problem was, though. Turns out the outlet I had the miner plugged into died, but not completely. Once I turned the miner off and unplugged it, I tested the outlet with a multimeter. The output was, and currently still is, 15VAC. Something that's also a bit more troubling, all other outlets in half of my house are now over-volting, including ones on the same circuit as the dead outlet. All are reading between 155-165VAC, which I know is a dangerous thing when it comes to sensitive electronics. They also have a higher amperage than my multimeter can read, which has a cap of 20A. I'm 99% certain that the miner did NOT cause this problem, but rather was the first thing to be 'punished' by the problem.

But with the good news comes bad news... Plugged the miner back into a stable circuit, turned it on, and cs3 (Board #4) is dead. Board 4 is the one that hit 101*C, which I would imagine any piece of equipment hitting the boiling point means the kiss of death. I'm planning on opening up the rig tomorrow to see if there's any visual damage, as well as reconnecting all of the cables. Will also reflash the SD card just in case. But, as it stands right now, the board is dead as far as I can tell. It always ran hot to begin with, averaging close to 6*C hotter than the other 5 boards, even with super cold winter air. Probably little to no thermal paste on there is my theory...

Last little question, but does anyone know if replacement boards are sold anywhere? Or if anyone, most likely someone on this forum, offers repairs?

Has anyone got board replacement from Innosilicon?
What's the procedure for board replacement?
Confirmed, my A2 110MH, 3 boards now not responding after many troubleshooting, i think best if just get replacement board.
Can the boards be purchase etc. assuming no warranty? Mine is less than 6 months old.

I think the temps skyrocketed because mostly of the cgminer restart loop. Increase that value, could have killed your miner with bad luck. Regarding the filesystem, here is a pointer:

Fingers crossed it works for you

Hi all,

I've posted before on the Ultra Under-overclock thread by emdje, but I thought I should post here since I'm using this image on my A2 Mega. Bought it this past January, finally got everything set up and working after replacing the power supply, and it's been working smoothly for about 3 months. Tonight, however, I received one of the automated emails from Mining Rig Rentals saying the rig is offline, which shouldn't be the case. I pulled up the control interface on my computer and saw something a bit unsettling. The cgminer log kept repeating the same message which was followed 10 seconds later with a forced restart, which kept repeating until I stopped the miner.

This is the most recent display in cgminer:

I've seen in another thread that a possible reason to this might be the power supply or a bad SD card. Since I'm not the best at computer coding, especially Linux, I'm not sure how to tell what the problem is. The power supply shouldn't be a problem since I put a brand new EVGA Suprnova 1300W Gold in about 2 months ago. The SD card came with the miner, so I'm not sure about it's reliability, but it works enough that I can still pull up the interface.

Also, another thing to note, right when the miner stopped working and displayed the message above, the board temperatures SKYROCKETED almost instantly. During the day they average about 52*C, but within 2 minutes of the error message, the boards (0 through 5) had temps of 68*C, 59*C, 80*C, 101*C, 97*C, and 55*C, respectively. They are receiving a strong airflow and no problem with air circulation to get rid of the heat, so I'm hoping that factor isn't a bad sign, and that it's just caused by the malfunction with the image, or whatever might be wrong. Hoping to hear back very soon with a possible solution or any ideas. Thanks

Worst case to find your IP address (I had to do this with all of the A2 units I bought from Zoomhash):

1) Pull the SD card
2) Mount it as a drive on a Linux machine
3) poke around in the rc.d directories off /etc
4) ONE of them will have ip address(es) in it

No, I don't remember the exact file offhand, and I'm not in the same state with my machines right now to go looking for it.

network IP information is in
/etc/network/interfaces

If it's set to a static address, or you want to change the address or set it to DHCP this is the file to do it. I set mine to dhcp by editing /etc/network/interfaces to reflect:

Code:

auto lo
iface lo inet loopback
auto eth0
allow-hotplug eth0
iface eth0 inet dhcp

Finding the IP address from another machine:
If I'm running a linux machine, I use 'sudo nmap -sP 192.168.0.0-254'. You would need to change it to your network, as it might not be 0.0-254 but 1.0-254.

If I'm running a windows machine, I use a program such as Advanced IP Scanner, as I linked in post #110 of this thread.

Also, the issued DHCP address can usually be found in /var/log/syslog on the miner, the last line in this snippit:
