Most probably you get a long latency connection from your rig to MRR's server... sometimes happen! Try to set failover strategy in TerraMiner and set first pool priority as MRR's and a second pool of your choice that it works well for you. If you get some share on the second pool means that MRR's server it's not fast enough to provide work to your rig.

infernoman -

You'll probably need to be more specific - although I'm no expert.

On your status page:
are your core temps < 100 on average ?
are all the pumps running roughly 3000 rpm?
are all the fans running 3500-4500 rpm?

looking through the front grill do you see the 'knight rider" lights - sequenced yellow lights?
are any red?

if its not under warranty - pop the top - which light is red?

any sign of leaks in the cooling system?

any lights looking through the side power supply screens - should be none

next onto the advanced page then the diagnostic report.....

hey guys i picked up a terraminer 4 that i didnt know was damaged. it has a red light on one of the boards. and it seems that 3 of the cores are underperforming or not working at all

just wondering if there is anything i can do to fix this?

Hello all, has anyone tried to lease their rig on west hash or miningrigrentals?  I will normally get around 1600 Gh/s mining on my own but I can't seem to lease it to a miner for more than 1 Th/s consistently on these sites.  Any idea why?

Same problem... my Cointerra stop to works just today! When it get powered it light on RED CTRL1 led for 2 seconds and nothing more...

Cointerra sell the BBB unit with preloaded firmware for 70$, but they should provid a SD card image to restore the BBB like KnC!!!

Can anyone extract data from BBB and post it?

Tks you all for any help!

Curious if anyone is good at fixing these Terraminer IV boards?

I have several that have a short, I do not have the bench power to test.

several that have usb connection problems.  I can connect direct from pc to usb with cgminer and have usb errors.  It will mine for a few seconds say usb error, disconnect, reconnect, hash for a minute or two, usb error - repeat

3 or 4 boards that look like the lights are working correctly but will not show up in the usb connection with beagle or direct PC with cgminer.

any ideas?  there is probably 6-7 TH if I can get it working.  I would pay some btc for detail instructions.

Thanks

Can anyone help me here?
Need an cointerra beagle bone image!
So it was lost after the update 09/04/14 Firmware 0.7.56 MD5: 2ACCF7DE2603490128A2A3A8266CEECD by standard method in the interface of device through software updates.   
Has anyone encountered a similar problem?
Help please!

Hi,

I have had 3 radiator  hoses spring leaks over the past few months so this is what I did- and I think it keeps things even cooler than the stock coolers.

To replace a leaky hose, remove the entire radiator / cooling block apparatus. Place it on it's back with hoses facing upward and cut off the leaky hose (you will loose no more than 10 ml of coolant, the precise amount is not important). Go to your local hardware store or Home Depot and buy a length of polyethylene tubing. Its the same hose that is used on your refrigerator ice makers or if you can find what Cointerra used that's ok too but the polyethylene is much, much stronger so it's never going to leak again. Cut the correct length and replace the hose but...

Connect the 1st end to the radiator and before you connect the other end to the block, fill the radiator up with as much "automotive anti-freeze". If you want to dilute the antifreeze with a little distilled water you can but its not necessary as most all antifreeze comes already diluted. After the radiator is filled up with as much antifreeze as will fit, attach the other end of the hose and replace the radiator back in the miner. A few air bubbles are unavoidable and does not affect the miner operation that I can see. My refitted automotive antifreeze miners all run on power level 9 with temps running in the mid to high 50s deg C.

Hope that helps.

So, I tore apart one of my pumps today since it apparently wasn't working and here is what I saw:

I have the dreaded D45 red light and I cannot seem to solve the issue.  I know its not the the thermal paste - successfully changed that on other TMs with no issue.  I used a mechanics stethoscope to listen to the pump and it seems normal, shows a normal RPM on the STATS page but for whatever reason (according to the diags) the cores overheat and immediately shuts down one board.  Tried swapping the connectors, pulling the J11 and a few other things but no luck.  

For what its worth, I haven't taken apart the other side of the pump since I didn't have fluid to replace what I would have lost had I done so.  Does anyone know what type of fluid it uses?  Perhaps I'll try that and take some pictures next.

I see others have had this issue but nothing I seen discussed thus far seems to solve my issue.

I reached out to this forum to purchase a used pump/radiator setup - waiting to hear back.  If not then maybe I'll try to the other suggested setup with the dual radiators.

Any new advice out there?

Thanks, I just have a couple windows of browsers open with multiple tabs.  It would be nice to have an overview to see a quick snapshot.

If anyone remembers the software, please let me know.

I've just been keeping ssh sessions open on each system.
At first I was going to go further into it, but ended up just relying on this as it works fine and gives the same info
you get from the web page.
Do something like this ( your mileage may vary, work it through) to get a 15 sec snapshot:

while :;do php-cgi /var/www/status_frame.php|sed -e 's//\n/g;s//  /g;s/<[^>]*>//g;s/^.*pted //;s/y\t*/y\n/'|grep .|tail -n 16;sleep 15;echo;rm /tmp/sess_*;done


So at a glance you can see what's up with each one. Be sure to 'rm' the session file which shows up in /tmp.
I also set up a cron job to see if the things get stuck, reboot them.

Depending on your number of screens, ten might be a lot, maybe you'd want to curl/wget and collate like that instead.
Also, seems like there was a guy who made some sort of software for these, but I haven't looked into it. I saw it on one of these
forums long ago.

p.s. DO NOT FLIP THE POWER CABLES ON YOUR MINER UNLESS YOU FLIP THEM ON THE PSU TO MATCH WHAT YOU DID ON THE BOARDS. POS SHOULD NEVER BE HOOKED TO NEG. THATS JUST COMMON SENSE. EVEN IF YOUR ...[/quote]

How does one determine which lead is pos and which neg on the mining board and the PSU breakout board.
Do you mean the pics of the Terraminer interior? The problem is, I have seen different TMs with the pos lead (black wire) in BOTH positions, so a picture alone without data as to where it goes and why is a possible accident, unless you can hook the leads up to either post. Thanks for the input though.

On mine, top-off and viewed down into the case, the blacks are the top-most of each pair on the power supply mounts. I checked the lower set to be sure, they are set up the same, so Black-Red / Black-Red from top to bottom. Which is not a definitive answer, of course, but that is what I see.  So, on mine, Blacks ( topmost of each pair on PS ) are attached to the posts closest to the centers of each board, Reds are attached to the posts closest to the board-edges.

I just bought several of these Terraminer units, What kind of software do you use to get a good overview of 10+ units?

Switching between each ip address is a pain.

Thanks!

A little help please. Like a genuine dunce, I removed the power cables when building a miner from spare parts and forgot the positioning of the cable leads on both the mining boards and the PSU breakout boards. Now I don't remember where either power cable end goes relative to the other end.

How does one determine which screw is pos and which neg on the mining board and the PSU breakout board.

Many thanks in advance.

i figured it was that was easy.  but wanted to ask before fiddling.  also the controller power was plugged into ps 2.   

much appreciated, can't believe you read so many posts :-)

thanks for your support!

Open it up and disconnect the USB cable going to the bad board.

got my hands on a terraminer iv with one bad board. 

is there a way to rewire the miner so that the good board will run with only one power supply? 

it seems it wont fully boot unless both plugs are connected.

Need a replacement pump - anyone parting out a Terraminer?  Will pay in Bitcoin if you like.
Will consider buying an entire machine for parts if the price is right...and of course it has at least one good pump
