I am having the same issue as you guys. One cta goes to 120c right away and shuts down.  it was working for for the past 3 months.   the other CTA runs amazing over 800gh all the time
the "bad" one always ran hotter. i replaced the paste about 4 times now and like 4 cores go to the sky and it stops. at its different ones just seems like something is shorting out or i dont know what the hell is happing.  any input would be great.  i used ic diamond themal paste on all chips the "good booard temp are way down and it hashes amazing the "bad board is still HOT!

edit did some tinkering. found that letting the board cool down and then just start the one sounds like a fan in one of the pumps is ticking...   also found that the "out" side of both cores on the "bad board" are really hot and the "in"side is cold. On the "good" board both side are equally Warm cound it be a pump issue? both pumps show speed but not as fast as the other board.  if the fins inside the pump broke off the the pump would stiill spin just be clogged/not going anyhting?Huh  im really tring to figure this out.    already had one of the power blocks that the soldered on the board break off that's why i opened it up in the first place. fixed that and now this heat/power/idk/short issue

1.616 Th/s. If I felt like restarting it I could get it to 1.618 Th/s. Before upgrading to firmware 0.7.6 I was getting 1.622 Th/s. I will say this though. Ever since applying Liquid Pro not only are my temps down so is my power usage. Before it was using 2200 watts. Now it is using 1965 watts.

Is anyone else's Terraminer throttling often? At first I figured it was caused by the high temps but now that I have the temps down it still throttles.

What temp does it reach before it throttles? what's the performance before/after?

I'm running on ICdiamond for about 2 weeks and I haven't had any throttling so far.

Previously the MX4 was good for 3 weeks, so I'm not sure how long the ICdiamond lasts. (the MX4 degraded into "dust" after 3 weeks).

When it disables/throttles the core(s) the temps go down obviously so it might not be evident that it's caused by the degradation of the thermal compound.

If a pump fails then it also disables the cores ( I had one pump fail on me - it produces weird noise before failure)

Having said that, I'm interested in buying problematic Terraminers. Pm me with the stats if any of you consider selling them.

 I am down to thinking that I may have a bad pump. Anyone know how to test that? Obviously something is telling the board not to start.

Bad pumps show as 0 RPM in the admin panel, iirc the boards will start with a pump failure.

eek, ive put MX4 on a few rigs here, id better check them soon after reading that, but the coollabratory stuff should be here tomorrow anyway (along with some hopefully less problematic KnC neptunes) but since its started getting warmer these things are dropping like flies, often i can get them back to life but not for long before they start having other issues

Please explain more about your units dropping like flies? Are they overheating to 120c and restarting? How are you able to get them back to life and what other issues do they have? Please update us how it goes after applying liquid pro very curious

My temps at the hottest part of the day (85°C) are around 62°C. So its not getting hot. You can see my temps on page 2 of the thread. Funny thing is it seems to throttle more the cooler it gets. What firmware are you running? I'm running 0.7.6.

 I was trying to think of what I was doing last time my board worked and so I decided to roll back the firware all the way to 6.32 and then 6.48 and viola.. the board worked again (kinda) It was slower than the other around 450 when the other was 600. I could power step it, but it would not speed up. I decided to go ahead and bring it up to 7.6 and bam! Board not working again. Sad I tried repeating and I get nothing now. No idea what is going on with this damn thing.

I just used the air compressor which did not solve the problem. I poured a little bit of 99.9% on the board and blew it off with the air compressor that did not solve the problem. The board is now in a tray soaking in the 99.9% for 10 minutes. I will let you know how this goes shortly. If that doesnt work I am going to ship the board back to Cointerra and plead my case. At this point a dead board serves no purpose

Yeesh, good luck. Use Q-Tips to get any other parts that the air compressor may not have.

Board is still not working. It has voltage but no led's light on the board and no miner. Im now done with this and have no other options other then to ship it to Cointerra and hope for the best

 I really am curious about the push button towards the back of the boards. My error sounds and lights change when I push it.

Swapped power supplies and unit still worked so that is not the issue. Next problem though, there is a push button near the jumper pins in the back of the board. If you press it, the leds, and sounds will make different noises and error messages. Has anyone played with these? and what does it actually do? What is it changing on the bios of the strike boards?

 Folks I am trying to help solve issues, but for the past 4 hours I am merely talking to myself aloud. Lets go to work and solve this shittery piece of machinery. Smiley

Wish I could help but I'm not sure what is causing your issue.

Do you get a better hashrate now with the system running cooler?

No I did not get a better hash rate. The terraminers are designed to run at 1.6Ths regardless of temp until a core hits 120c then it reboots. I also noticed my miners would have one or two cores that where significantly hotter then the rest. I opened my last 3rd machine to cool it and noticed that many of the screws that hold down the cooling block where not even screwed in or they where barley screwed in leaving the cooling block lifted up and not having good contact to the core. Another fail by cointerra. Only apply the LiquidPro to the cores, not the cooling block. Just like the photos I posted.

FYI, my third machine when put back and turned on failed to boot up CTA1. Ive cleaned the board twice but still no mining. It has power but does not boot up and coming online so currently only CTA0 is mining. I will most likely pull this board again and give it a full bath in a last desperate attempt. I was so critical in doing this last cooling job just because of my previous experiences and still I fucked up with no idea how.

If you decide to open clean and cool with LiquidPro its a huge risk but if you can pull it off its well worth it

So you only applied it to the dies? Interesting. What temps you getting with it now? When I applied it I put it on both the die and the water block (just enough to cover where the chips make contact). Figured if it wasn't applied to the water block also it wouldn't flow right.

Ive given up on tech support, they send the same canned response to everyone and never get back to them. The machines where all mining when they arrived so I know they worked. And the board is getting voltage so its not totally fucked. Im leaning towards the idea I may have got liquid pro somewhere but I really dont think I fried or shorted out anything. If I got one board working I surely can get this one. If there thermal grease got on the board before from my mistake and caused it to stop functioning then I cleaned it and got it working I should be able to do the same with this non-functioning board. I noticed Frys has 99.9% Isopropyl so if the air compressor doesnt work ill go get some of that. To bad I didnt live in Texas and I could walk into Cointerra with my board and plead my case in person. Unless the place is a fortress impossible to enter like a prison.

Thanks for the suggestion to use the 99.99% I will try to get my hands on some of this. Before that I will try the air compressor idea also. Regarding your problem I have never experienced the LED issue. My dead board never lights up at all thats how I can tell its not functioning. I wish I could be of more help to you.

 Thats what makes me think you have an arrant run off from the Liquid Pro. Grounding out. May be wrong, and its possible you had one and fried it. May be possible you were shipped a POS like me.
 
 They actually responded very late today, and guess what I got... Answer 101, copy and paste. Here is the entire email...


 Richard.. you should have already sent this to an advanced tech if you care anything about the small customer, but yes I will do so. Why did I not get a call back, and the standard cut and paste response? I have read numerous posts on the bitcointalk forums. This is your traditional cut and paste response. Furthermore, I do not know why you would ask for this as the secondary board is obviously not working. These stats from the working one will tell you nothing. I spoke of the issue months ago, and you simply closed the case a few days ago. Please, I implore you to respond with sincere advice, or real technical help.

    I have the latest firmware, I have reset the machine 20+ times. Did a hard reset and put all the config's back in and only CTA0 is working. Half the machine will not start. I have tried rolling back firmware as well to the other versions and nothing works. Both PSU's appear to be working. What else can I do?

Hey Scriber how would you go about giving a "full bath" to the board? do you wash it with alcohol or something else? I'm asking because i'm in the same boat as you, I reapplied the thermal compound and now one board does not want to work. CTA0 is working but CTA1 powers up but does not do anything. I've looked at the board all over and don't see anything wrong with the board so i'm willing to trying just about anything to get it working again.

 Do you exhibit the same error codes on the led's as I do? I am asking so we can solve this. I don't believe half the unit is fried, I am starting to suspect a bad pump.

 Swapped power supplies and unit still worked so that is not the issue. Next problem though, there is a push button near the jumper pins in the back of the board. If you press it, the leds, and sounds will make different noises and error messages. Has anyone played with these? and what does it actually do? What is it changing on the bios of the strike boards?

 Folks I am trying to help solve issues, but for the past 4 hours I am merely talking to myself aloud. Lets go to work and solve this shittery piece of machinery. Smiley

Thanks for the suggestion to use the 99.99% I will try to get my hands on some of this. Before that I will try the air compressor idea also. Regarding your problem I have never experienced the LED issue. My dead board never lights up at all thats how I can tell its not functioning. I wish I could be of more help to you.
