Topic: Cointerra Hardware Support **Unofficial - page 22. (Read 57004 times)

I too have problem with CTA1. Do you guys know which board is the CTA1?
is it next to the 2 Power Supplies?
TIA

I want to buy some mining equipment and and checked many websites already I was interested in Cointerra's Terraminer but I am seeing that this company is not that good and their support is some kind of joke. And I will be buying now from http://www.gawminers.com/ instead. They have a lot better client support and this is what I like the most.

Thanks. I've ordered that as well.

I'll compare it to the thermal pads when everything arrives.
 

I used this http://www.frozencpu.com/products/7038/thr-41/Innovation_Cooling_Diamond_7_Carat_Thermal_Compound_-_15_Grams.html

I also used Arctic Clean to clean up the huge mess first. You want to put a small drip of compound on each chip. They say pea sized on the instructions but I used a little less for each chip since they are a lot smaller than a CPU.

I have had it running stable for 3 weeks now with no temp rises.

I had tried Arctic silver first but that didn't help at all, the Cooling Diamond was like night and day and has been working fantastic.

What is the intake/exhaust temp?

Thanks. For the time being I have ordered some samples from http://www.tglobalthermal.com/

I would be interested if the Liquid Pro last long. I've used mx4 but it started overheating after 2-3 weeks.

I'm waiting for my wc block to arrive next week too, hopefully I'll be able to overcome this throttling issue once and for all. As CTA0 is fine I'll focus only on CTA1.

Hey guys thanks for starting this thread, seeing as Cointerra shutdown the forums this is the only place i can find help. I've been running an April batch for two months now and today one board did not come online. I opened it up to see why only one board was going online and noticed that LED D45 was red. Does anyone know what this means? and is there is a way to fix it?

Whatever you do, do not buy these thermal pads ( http://www.frozencpu.com/products/16878/thr-164/Fujipoly_Extreme_System_Builder_Thermal_Pad_-_14_Sheet_-_150_x_100_x_05_-_Thermal_Conductivity_110_WmK.html?tl=g8c487s1730&id=T4zpcMmV ) I bought these and my temps got worse. Temps went straight to 105°+. There was a guy on the Cointerra forum that used Collaboratory Liquid Pro and said it brought his temps down.

nothing permanent, im looking at liquidmetal pads to replace the compound, ive also heard that there is the possibility the shims that protect the cores from the block being tightened too far may be a shade thick so i may try sanding them down a bit to try and get better results, i wish they hadnt hardcoded all the cutoffs and detection things (eg one of the units i look after cant read the waterpump hence the board wont start with that pump connected) were it not for all that we could easily swap out the cooling system in place for a stronger cooling system, not that its not possible still, its just a bit more of a pain

one thing that does seem to help is regular restarts, you can add a cron job to resart the system every few hours which seems to help a bit but not too much

Thanks for creating this thread as I'm sure many owners (like me) have ongoing problems with these supposedly multifunctional paperweights.

It's been a few months since I've turned on this miner and in the beginning it worked fine hashing at 1.6TH with temps in the range of 75-85C (core).
My troubles started when CTA1 started to report inconsistent temperatures usually +15-20C above CTA0 while ambient temps have not been changed.

Shortly after this anomaly CTA1 started to throttle very often. I have cleaned the original thermal paste and reapplied a known quality brand.
This seemed to fix the issue for several weeks and CTA1 was within 5C range and I was a happy miner (my overall temps have gone down considerably too).

Next I encountered the "dead core" cointerra disease, as half of CTA1 disappeared. I was reflashing and restarting this diabolic device multiple times and disconnected/reconnected all the connectors inside to resolve this issue.
 
Couple of weeks after I'm again seeing CTA1 throttling very often meanwhile the reported hashrate is 1.3-1.5TH (temps in the 80-95C range).

I'm thinking about ordering quality thermal pads due to the unevenness of the chips surface and using a proper wc loop ("luckily" I have spare parts - will report back when it's done).

Do any of you found a permanent fix or tried something else with success?

the hack is as far as im aware limited only to the beaglebone, thankfully (in a way) the goldstrike boards are stand alone, crack the lid off, disconnect the USBs and wire the boards directly into a linux PC with a cointerra enabled build of cgminer on, or just remake your own image if you really want to stick with the beagle, im getting rather clued up on repairing cointerras now (not bad for someone who doesnt actually own one!) maybe i should start some sort of blog on the potentail fixes etc, especially since the cointerra forums died

They suck as a company, my Cointerra has been hacked and is only running at 50% hashing capacity.  The other 50% is hashing for some hacker and not matter what I do I can't seem to restrict access.  Cointerra gave me instructions on a recovery process that should kick this hacker out but that failed to do the trick.  Cointerras response was there is nothing else they can do and has ignored all my emails and no one picks up the phone when you call.  The employee who I was working is named Marshall and if he is reading this I have this message to you "GO FUCK YOURSELF".  If you want to message him and fuck with him his email is [email protected].

Apparently, the cointerra people are starting to look more like BFL. First the stopped responding the support and phone calls. After issue from sever buys regarding their cointerra stopped working they now took the forums down as well...

Let's start a thread over here for miners who need support regarding ther 30lb Paperweight and if it can be of any use
