So...I finally got my December batch Terraminer IV today-the original December $14400 batch version.  I was super excited so I decided to take some photos, you can click to the imgur album here: http://imgur.com/a/dbtmd or just look below.






Now, setup was a little bit tricky.  First off, there were no instructions in the box on what to do, so I headed off to Cointerra's website where they promised they would publish directions before shipping the first unit, except there were no instructions there either.  No matter, I looked in the forums and plugged in my networking cable, and plugged in power to both PSUs and the fans powered on.  Except the Terraminer was nowhere to be found in my router's DHCP tables.

As it turns out (after a call to Cointerra to figure out what was wrong) you should actually turn on your Terraminer by doing everything in the following order:

1) Plug in the ethernet cable to a working router that you have administrative access to.
2) Plug in the power cables to the two PSUs, you *must* plug in the power to BOTH cables within 3 seconds of each other.
3) You should now see the orange LED power on on the front of the unit where it says CTR1-this LED shut off for me after a few seconds so you have to be looking at it right after you plug in the PSUs.
4) Now wait about 1 minute and check your DHCP tables, if the unit powers on correctly you should see the unit in there.
5) Open your browser and type in the IP address that you saw to get to the control panel for the Terraminer.
6) Log into it-the username defaults to admin and there is no default password apparently.

From there it's actually pretty self explanatory, you click the configure button and put in the pool URL and pool worker name/pass then the unit will connect to the pool and start mining.  When it does this the miner lights will start blinking away and the unit will become insanely loud-this thing has six high speed Delta fans blasting away...unfortunately as you can tell from my pics it's not in a server room for me.

As for performance?  Well, the control panel seems to say it's running at 1.5Thash, but unlike my BFL hardware where what's reported in CGMiner is more or less what the pool sees I can't get BTCGuild to see any more than 1.3Thash and it seems to fluctuate between 1.2 and 1.3Thash...this is severely disappointing right now and I've been playing around with pool settings to see if I can get any better performance but I'm basically mining 2/3rds of what I was expecting and obviously it's over 2 months late.  All things considered for $14400 I could have had two Jupiters mining away at almost the same hashrate for 5 months now...even though they're sending another unit in March to try and make up for the delays the much lower hashrate is actually now the major issue-I'm honestly not sure how any of the later batches will ROI if they don't actually ship the full 2 terahashes.  I have no idea how their control panel is showing such optimistic hashrates either.  Overall I have to say that this whole experience has made me really hesitant about doing any sort of pre-orders ever again, I ended up paying about $11 per gigahash-yes this price will go down once they actually deliver a March unit but right now I have no idea when that will actually get here or even how much mining power it will have so if it ends up being 2.6Thash being delivered half in February and half in April for $14400...

Edit: After some fiddling around (took cgminer down temporarily, changed the power setting around, restarted everything via SSH, etc.) I'm seeing 1.7Thash locally now instead of 1.5Thash and I've switched to Eligius...the hashrate is still climbing up at the moment so we'll see where it settles-maybe Eligius works better than BTCGuild with Terraminers?  I know Cointerra was testing on Eligius so maybe this is the only pool that really deals well with these.  We'll see soon enough I guess.

Good summary.

Does Con have a cgminer build that could be run on a PC over USB?  Maybe the beaglebone controller is underpowered for the hash rate.

There is a USB port on the unit but when I called up it didn't sound like we were supposed to do that, I'll have to see if this is an option given how they're hooked up-I know on a lot of Bitfury boards there was no way to bypass problematic raspberry pi's.

On a side note it honestly doesn't seem too much like it's the beaglebone at fault, one of the boards is basically hashing at only 600Ghps (and that's the local number, I'm sure it'd be like 500gh/s on the server) whereas the other one runs much faster.

2) Plug in the power cables to the two PSUs, you *must* plug in the power to BOTH cables within 3 seconds of each other.

I ran mine for about a half hour on the lower PSU only (the other one doesn't power the internal controller) while I looked for an extension cord to reach another outlet on the other leg of my power.  Hashrate doubled after plugging it in, no fiddling or rebooting required.

What I did waste a bunch of time was on the fact that it's dhcp only, I was assuming it would have a default IP and wasted a long time looking.

Well constructed box... it's also AWESOME on p2pool, lowest stale rate I've seen from any mining hardware.

hey guys what's the noise like of these units? can you see if the intake or exhaust fans could be replaced?

So, when CTA0 shuts down and CTA1 is still mining how do I reboot the miner?   Just reboot CGMiner in the web interface?   Have you figured this out yet?
The fans really blow the heat a long way don't they?

Very, very, very loud and I wouldn't replace anything, it needs these super high flow delta fans to keep the chips cool-it's basically server grade equipment.

I'm not sure when you would ever encounter this scenario, they basically mine as one unit, you don't direct one board to one pool or anything like that, all the hashrate is directed at whatever pool you point it at.  You can SSH in and reboot it that way and it seems to reboot everything.

Yeah, I was panicking too because I couldn't even see it in DHCP and I had rebooted it several times and swapped out the ethernet cables left and right.  Turns out all my ethernet cable swapping was the issue-if the ethernet cable isn't plugged in when you power the unit on it doesn't bother to try the DHCP again so it never shows up anywhere.

To run this thing you really have to have access to the DHCP data on your router or else you'll have to scan every single local IP to try and find it.  There is a way to set a fixed IP in the control panel but of course you can't connect to it until you have the IP...

Great that you finally got your unit !!

I'm sure the performance/hashrate  will improve as you get used to tweaking a bit ..

LOUD .. you say ..
Like you can't stand to be in the same room .. LOUD ..
or
Your wife is going to leave you if you don't turn it off .. LOUD  Grin Roll Eyes Shocked

Jim in CT ..

I'll try to take a video later if I can, but if you're planning out where to put it I would strongly recommend a dedicated room that has good airflow.  I can actually hear the TerraMiner from outside the front door of my home because it's sitting on my dining table.  It's more or less equivalent to my blow dryer just with a lower pitch.  

Luckily my girlfriend is used to dealing with my insanity since I used to run the Single SCs...but to be honest this is louder by far than even several single SCs.

Edit: After some fiddling around (took cgminer down temporarily, changed the power setting around, restarted everything via SSH, etc.) I'm seeing 1.7Thash locally now instead of 1.5Thash and I've switched to Eligius...the hashrate is still climbing up at the moment so we'll see where it settles-maybe Eligius works better than BTCGuild with Terraminers?  I know Cointerra was testing on Eligius so maybe this is the only pool that really deals well with these.  We'll see soon enough I guess.

Hey testerx... I'm seeing the same thing with mine.... local cgminer reads 1.5 to 1.6 but only seeing 1.3 on the pool.  Did you "fiddling" get things working better?  Can you expand a bit on what you "fiddled" with?  Smiley  Thanks man!

Came across this and saw the laptop/cointerra on the desk and instantly remembered this thread.

50/50 it's a scam but the number is local.  But ROFL'ed at the 20k or 25btc then really rofl'ed when I was like wait those aren't his pictures!

To be clear: This is a point of contention at all times with what others seem to want and what I end up putting into the cgminer git master. I try wherever possible to make the on-screen hashrate match what you are actually producing in shares whereas other implementations of drivers like to display what the device thinks it's hashing. In the case of the distributed binary from cointerra, you are seeing the latter. I am planning on making the cgminer master code to do what all the other drivers do, although it appears no one has been brave enough to open up their machine and plug their device in via USB to a regular PC to try it out yet. For the time being, the code in cgminer git master is almost identical to what cointerra are releasing as binaries within their BBB firmware, only newer.

Unfortunately using an external controller is not possible without opening the box, and that would void the warranty.

One of my miner keeps going

1 TerraMiner Offline:

    127.0.0.1

what's the reason?

every time i restart cgminer it says config might be crashed?

From the Cointerra user guide.

"To boot up the TerraMiner IV connect the power cords within 3 seconds of each other. If they are not both powered up within this time it is possible that the BeagleBone controller card will not recognize both GoldStrike boards inside the TerraMiner."

There is a ton of detailed status information that can be seen in the Advanced/Stats page.  You can see the performance of each of the 8 cores on each ASIC including, hardware errors,  voltage and temp.    I have seen issues with one core on each ASIC that have shown as low voltages and hardware errors.   Right now seeing no issues on any cores.  Not sure if these were intermittent issues or perhaps some temp related issues on the first day of operations.

I am managing a Cointerra for the first month of its life.  I have the two plugs running off of two separate 110v circuits, which they recommend as well.   You can try unplugging and replugging as a restart. (I have done a few of those type of restarts) You also have have the small hardware reset button on the front panel that you can press with the end of a paperclip.  (I have done a couple of those restarts)

Due to Eligius stats collection and reporting issues, I couldn't get a new payout address on Friday.  So for the first 3 days I had the Cointerra paired up with an Antminer to the same payout address on Eligus so I could get at least some reporting from Eligius.  The actual hash rate gain from the Cointerra was about 100 to 200 GH less on Eligius than the 1.6 TH what I was getting reported locally.  I finally switched the Cointerra over to a separate address on Eligius a few hours ago and the Eligius stats are now looking better.  1.56 TH reported on Eligius and 1.62 TH locally.  Need to build up more long term stats on Eligius of the unit by itself before I can say anything conclusive.

Unfortunately using an external controller is not possible without opening the box, and that would void the warranty.

Edit: After some fiddling around (took cgminer down temporarily, changed the power setting around, restarted everything via SSH, etc.) I'm seeing 1.7Thash locally now instead of 1.5Thash and I've switched to Eligius...the hashrate is still climbing up at the moment so we'll see where it settles-maybe Eligius works better than BTCGuild with Terraminers?  I know Cointerra was testing on Eligius so maybe this is the only pool that really deals well with these.  We'll see soon enough I guess.

Can you provide some instruction on how to adjust power settings and restart via ssh. I'm on Eligus and getting about 1.4 on pool but loally shows about 1.6

After running over 24 hours on Eligius with its own payout address, the Eligius reported performance matches the local performance, about 1.62 TH.

I am still running into the problem where one of the "cores" will sometimes stop hashing and total hash rate will drops by about 100 GH both locally and on Eligus.  Manifests like this in the stats.



ASIC1Core1 obviously the one not hashing.



A reset of the machine gets that downed core running again and the hash rate up above 1.6 TH again.

You can see in the Eligius plot the rate drop down about 100 GH about 4 hours before Feb 19th.  Not sure what causes this intermittent outage of a core for a long duration.  And it has always been this same core and similar symptoms.



... sent inquiry on this to Cointerra

We are also seeing some issues with one of the CT miners:

The unhealthy miner:


And for comparison a healthy one:


Miners are on different networks, and first miner's has been mining a little on the backup pool, so we are suspecting some network issues at the moment.
Local network ping to the miner was healthy all time, so now we are checking external network connection.
The miner has also completely stopped once and had to be rebooted. Unfortunately miner does not expose any logs, but only current stats Sad

Thanks for sharing the issue with not hashing core, we will also try to look for that as well.

Can you provide some instruction on how to adjust power settings and restart via ssh. I'm on Eligus and getting about 1.4 on pool but loally shows about 1.6

To restart via ssh and the linux command prompt:

# ssh root@[address of your miner]
<prompt for password = 'cointerra'>
# reboot

.. then wait for the machine to restart. It's very similar if you're using putty.

Can someone tell me how to reset the password for "admin" using SSH? I cannot seem to login anymore using the GUI interface. I still have SSH root  access.

I can do a master reset, but i want to avoid that process.

To Cointerra, when you give us an option to change a password, make sure you get it twice so people like me with fat fingers do not type in the wrong letters.


I have the same problem as others on this forum, I do not get full speed as advertised. One runs at 600GHash and the second board runs at 800 GHash.

What I paid for: 2TH
Performance claim after 2 months of delays: 1.6TH
What they finally delivered: 1.4TH

Thanks!

Interesting to point out is that these same cores that eventually stop working after a few hours are also responsible for errors while in full operation.

I plan to capture the output from /tmp/cgminer.log next time it stops hashing correctly. Currently this is what it looks like:
https://dl.dropboxusercontent.com/u/2009/cgminer.log

ckolivas, what must be done on a PC that can't be done on the Angstrom Linux/BeagleBone? If need be we could build a version of cgminer and plunk it into a running system.

I'm not sure what the question is. Cgminer should compile on the BBB the same as a PC since it's just running linux. The distributed firmware+cgminer on the beaglebone is just older than the code in master cgminer.

Ok, in that case I'll just change out the binary at /opt/cgminer. Earlier in the thread you mentioned hooking up the units to a PC directly, and I was wondering why this was necessary. Re-reading things, I guess the reason was to isolate a potential problem with the BeagleBone itself, as well as to switch from the more liberal hashrate estimation method.

Unfortunately I haven't had any problem with a reported-vs-actual hashrate, so my doing this is probably useless.

byte1, perhaps I was a little unclear. Try this:

# cd /Angstrom/Cointerra/
# echo 'admin:' > ./lighttpd.password

I have not bothered to change the hashmeter in the code yet since I can't even test it on a real device any more to see if I've changed the code correctly. I don't have a device and I don't even have remote access to one any more...

I'm really curious why some people see the same hashrate locally and on the pool despite us all using the same firmware and the same pools...the pools seem to show the same share submissions as the local panel so I'm really at a loss as to how there are such hugely different hash rates being calculated.  How are some people seeing 1.6 locally and 1.6 on the pool when I get these:
http://eligius.st/~wizkid057/newstats/userstats.php/1MwayhowetdFh7gQHVmKv3LYWUjfwsZ2B3 (my better December unit that claims over 1.6Thash locally...about 1.45Thash on Eligius, noticeably worse on btcguild)
http://eligius.st/~wizkid057/newstats/userstats.php/1MiHnbJ5Kiab9SskUGm5quyhx4aJGYRBYu (my January unit that likes to randomly drop one of the boards and definitely has weird connectivity or mining issues...if you're wondering it claims it's mining at 1.5Thash locally but Eligius sees 1.35Thash or so).

So, when CTA0 shuts down and CTA1 is still mining how do I reboot the miner?   Just reboot CGMiner in the web interface?   Have you figured this out yet?
The fans really blow the heat a long way don't they?
I'm not sure when you would ever encounter this scenario, they basically mine as one unit, you don't direct one board to one pool or anything like that, all the hashrate is directed at whatever pool you point it at.  You can SSH in and reboot it that way and it seems to reboot everything.

I had this exact scenario this morning. Woke up to CTA0 offline, but CTA1 still going strong. I ssh'd into the unit and rebooted it, which seemws to bring everything back online (for now).

I am still running into the problem where one of the "cores" will sometimes stop hashing and total hash rate will drops by about 100 GH both locally and on Eligus.  Manifests like this in the stats.

[image snip]

ASIC1Core1 obviously the one not hashing.

Same problem, and same core for me. CoinTerra support noted their releasing new firmware soon that should help with this, but we'll see. It's bad enough I paid for 2TH/s but am only seeing 1.2.

It happened whit me as well. I think my case is that the board that is next to the Power Source heats more.


I had to open my box to cool the terminal in the power source.


It has the ventilation hole but no fan to circulate the air. So the miner heats more and wen it gets to 95ºC it throttle down the miner.


CoreTemp2 is the one that gets to 95ºC


EDIT: Was probing the Terraminer and found the FTP port open.

The power supply has a fan, it's just not visible. It *does* ventilate the air though rather poorly (the pictured end is the exhaust). The PSU is rated for something like 105C, so I wouldn't worry too much about *it* getting hot. Although some heat is radiated from the PSU to the heat exchangers / water radiators, it isn't a huge deal. If your cores are hitting 95C (the safety cutoff) than your ambient air temperature is too high, or your air circulation is poor.

There is a lot of variability in performance and temp among the units.    I am pumping 50F air into the machines right now and some chips are at 60C and one is at 113C.   Some chips within the same unit have a spread of 30C so I would not assume his problem is just his ambient air/airflow

That's mental, something is wrong. Only mil-spec or special analog chips are designed to operate that high. Someone didn't put your waterblock on right, the temperature sensor is wrong, or it skipped QA altogether. I'm not saying you're wrong, I'm just worried for your sake.

It is more than one.    If I could open the machine, I expect I could fix it.    I cannot without voiding the warranty.   I will RMA, but it is hashing well.    Some have one board at 60-70C  and the other at these temps.    Likely bad pumps which is strange since the waterblock company surely does not have this kind of reject rate.  Or a pinched tube etc.

it's also AWESOME on p2pool, lowest stale rate I've seen from any mining hardware.

We've only just received our unit...  March batch so at least it arrived in March.  Started mining on Eligius, was getting arounf 1.6TH out of the box, so not too bad considering.  However, just switched to P2Pool, and hash has dropped to around 1.2TH.  Any special config options I need to look at?  Rejects are reasonable... ~4.5%...

The newest firmware (0.7.6) has poor p2pool performance for some reason. I have not yet heard an explanation, but there are a few confirmed reports of this issue. Mining on big pools (e.g. Eligius) works fine. If you want to mine on p2pool, downgrade to 0.6.48.

The efficiency is just not there. Sell it.

how much you want for these 150 extra Cointerra Terraminer IV units?
Do they still hash, im looking to create an old vintage mining garage for the kicks of it (must hash though)

Let me know
