Cointerra Hardware Support **Unofficial

[sLide.]

Anyone still here?  Need some info on my CoinTerra miners are not mining at all...

Yeah, I'm not sure either, sLide...  It has been over a week since I posted and no one responded back to me either...  I have been having a hell of a time with my CoinTerra miners as well and thought I did all the right things and I'm still not getting them to mine at optimal output and they are still overheating.

Just from my very basic understanding of these machines and from what I have learned from this forum, I would think that perhaps either you have some blown or about to blow or burn out Mosfets or other electrolytics on the board (the medium sized to small electrical components soldered into the outsides of the boards around the GoldStrike chips and liquid cooling blocks).  The chips could also be having serious instant-overheating issues, so the board is shutting them down before the BeagleBone boots up all the way so your CTA's are not even coming up at all when you boot it up.  The best thing to check is to take the cover off and power it up and see what the LED chaser lights at the front of the boards are doing.  If they light up and promptly go out, it could be from overheating the chips.  If they don't light up at all and/or the fans aren't running at all, there could be another issue with the board that has basically killed it. Either something is causing the board to short out or otherwise stop the flow of electricity from flowing though all of the circuits.  It does seem kind of surprising that both boards would be dead in the machine though - usually I have seen that only one board will go completely down but the other will tend to keep working for whatever reason.

Good luck with it...  You'll probably need it as I haven't had too much luck with these things myself! lol...

Thanks! Hope you get your issue figured out.

FYI - if anyone needs parts for these I likely have what you need outside of a new hashing board.

PM me.

ne one needing help pm me. i will pm the 2 dudes above but if ne one else is having issues getting their miners to mine shoot me a message. im usually here to help if needed and have repaired more of these then i can count from pumps to boards to psus lol so ya just lmk what u need and i will do my best to help.

Hey Guys, sorry I have not been able to reply. I did just send someone the firmware, so I hope that helps.

If anyone else still needs it, here is the last stable version. This is what most, including myself, are running.
TerraMiner_0.7.56.tgz 11.4 MB
https://mega.co.nz/#!mUUUDagJ!hFa3bpwmTG_sxREnHYc5H1FPqxu_6oKwr2D5KU4gnlc

Here is the manual.

If you want the other versions, they are below

TerraMiner_0.6.32.tgz

If you are having problems with the miner not doing anything from the web interface, make sure its connected to the internet first. If it cannot connect, it will not work at all. Past that, crack it open and go USB right into the miner (CTA) and use cgminer to try and wake it up. You can also do a firmware update/rollback and see if that changes anything. However, you should be able to run it right from a PC with no issues if the hardware works. I just had one of mine start to die and it is the cooling system. Something actually broke inside of it (the pump) and clogged up the line so it was heating up and turning off. I whacked the line out of the pump and could feel objects moving through the line, not good. However, it is running again so there is hope. If overheating is your issue, dont be afraid to smack the pump a little while its running to see if you can get it flowing again. That has worked for me on several occasions.

Good luck!

thank you LeviWalker for the links to the firmware

mine are all dying too and am just beginning to start tearing them down and following all the suggestions in this thread

again, thanks and MUCH appreciated!

Ping me if your coolers are bad, I have 2 used ones left that are good.

Hey folks,
I plot to buy a terraminer iv 1,4. Now i read a lot but couln't figure out how to make it silent. I also read about hacked mashines?! How can i identify that.

How much would you spent on it?
Are there better Beginner Asics?

Hope you can help me

Buy an S3/S5 for a beginner ASIC.  The Cointerras are unreliable, power hungry, and temperamental.

[ninfan]

All Antminers i can get are to expensiv they will be rentable after 250 days. Thats to long for me.

How about my other questions?

[nombreyata]

HELLO, Sorry, my English is not so good.
I know you know a lot of information , and would be most grateful if got here to help me with this problem: https://bitcointalk.org/index.php?topic=638180.0
We could do whatever you want, i could pay you for your help, but I need help .

Disconnect your power cables from the board and check for a short between pos & neg.  If there is, the psu will not start.  Easy fix is to get a server psu and put 12V on there for 1-2 sec at a time and let the component burn up, normally one core will be gone after this, but 7/8 working is much better than 0/8.

Good Luck. 

btw, what do you pay for electricity USD/kwh? 

[Prelude]

This is 1.2w/GH hardware, right? Need really cheap power to still be running these.

[nombreyata]

No re-login.. I do not think it would respond. Thanks altcointalk14.. I will try to do that. 

Did you do that, it works? 

Change the sources of power , they had no problem.
I have reviewed my card more carefully. Everything looks great.
When connected to electricity, the orange light of death.

If you know the cost of my electricity, do not believe it, is: 1 months , with terraminer on, the cost of electricity is 1$ 

[numnutz2009]

has ne one heard anything about a posible volt mod for these miners?? the prices have tanked and they can be snagged up for next to nothing these days but the biggest issue of course is the power consumption....these would be great rigs if the watts per gh/s could be improved and im sure they can SOMEHOW. i can repair the boards i just dont know what to do to figure out a posible volt mod....so basically i can work with already defined components but figuring out what to replace and what to replace it with is beyond me probably because i dont have proper schooling but ne way is you change the level in the config page from 1-9 the power consumption is the same throughout each level which shouldnt be that way. if the voltage was being modded with the power level then they should show some increase in efficiency even when comparing level 1 to level 9 the consumption is basically exactly the same which is horrible.

these things have pumps die because the heat is too much for them 24/7 365. the pumps dont actually die most of the time they just dont spin until fixed but running a machine with a siezed pump with kill the pump shortly after it siezes so its best to unhook them. if the efficiency can be made better then running them at much slower speeds isnt an issue for me and probably many others out there since they will be more reliable, use less power, will have fewer failures, and most impacting to the small/home based miner....they will be much quieter when running.

if ne one has ne info on a volt mod please pm me since i dont check this thread too often.

[helipotte]

The voltage is firmware controlled.  Just run them at power level 1 or 2.  Mine do about 0.8W per GH this way.  Power level 2 is 1024GH@800w at the wall.

They are  much cooler and quieter too.  I am running these on 240V power.   

Just as a test I turned a unit up to power level 9, 1596Gh@1900W.  Ouch!

i just got a cointerra and setup my pool and it connects but doesn't hash. both boards show up but nothing happens

What are the lights on the hashing boards doing?

[cohnhead]

maybe is it possible pool (s) are not set up correctly in configuration.
set up more than one pool

[BLOCK_C]

Your pump speeds are reporting zero RPM which means the LCA's have failed.  You have to replace the LCA units.  I have a few extra if you're interested you can PM me

[wikkidtt]

It's all good the person I bought it from took it back and I bought 2 more sp20's and decided I was better off as the cointerra doesn't seem to be a set and forget device. I've been mining with antminers/spondoolies and I'll just stick with that.

Just for knowledge what does LCA stand for?
