CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s

[machinationus]

Yes, I used 12 gauge...the breaker is double posted...but it says that its internally connected.  Did I f-up?

12 gauge is good for 100% duty use at 9.33 Amps, check the charts(they will vary) for 100% duty. and max loads means for a few Milliseconds.
Any thing over 1000 watts should be 220-240 volt period as:
1. you can use smaller wire
2. Balance load on transformer, or inverter.
3. Use LESS overall VA and Watts
4. Most all power supply's will accept 120-240 just fine. Check name tag.

Never ever use a breaker/fuse that is larger that the 100% duty of the wire! The breaker/fuse should always be the weak link!
Larger wire than listed is most always cost less in the long term as less is lost from ohm loss (waste heat).
Hire a Electrician and get your loads balanced !!!

I've rebooted 3 times, but the second chip has never started

I want to open the box and troubleshoot, but the systems are sealed and I don't want to lose warranty support, so I'm waiting on "support".

Personally I would get 2 pieces of information they are going to want.  You can get this without opening up the system.

1) Open an SSH connection and run

# /opt/cgminer -n

It should spit out something like the below.

 [2014-02-13 01:08:49] USB all: found 4 devices - listing known devices
.USB dev 0: Bus 1 Device 3 ID: 1cbe:0003
  Manufacturer: 'CoinTerra'
  Product: 'GoldStrike ASIC'
.USB dev 1: Bus 1 Device 4 ID: 1cbe:0003
  Manufacturer: 'CoinTerra'
  Product: 'GoldStrike ASIC'
 [2014-02-13 01:08:49] 2 known USB devices

2) Create a debug log of your mining
  - vi /etc/init.d/S99cgminer
  Add a -D option like such
        /opt/cgminer -c /Angstrom/Cointerra/cgminer.conf --api-listen --api-port 4028 --api-network --cta-load $CTA_LOAD -T -D > /tmp/cgminer.log &
  - Restart the cgminer service like so
    /etc/init.d/S99cgminer restart
  - Let it run for 15 minutes.  Make sure the 2nd ASIC doesnt start.
  - ftp the log file from the cointerra.  Its in the /var/log/cgminer.log
  - Email the log file and the info from step #1 above.  It should help speed up the process.

After you are done with the above just reboot.  The ram disk will be restored and the -D option removed.

I would also like to see the log file so I can ensure my cointerra-monitor notices the issue and will send me an email if mine ever does the same thing.

There are differences in the individual chips, some will naturally run hotter than others...in addition, mounting the waterblocks is not going to be identical on all chips....so there are a lot of variables that could affect temps...as long as they are in a safe range you should not have anything to worry about.

@jjiimm_64...well, due to the outlet being limited to 20A...wouldn't it "go" before the wires (unless there is a short circuit in the wiring or something...), which should handle 20A just fine.

When I say 'running a 220'  I mean  run 10 gauge wire from a 30 amp breaker to a 30 amp twistlock plug.. get a proper server strip with c13 cables and you will be able to run 3 terras and be more efficient and safe.

OK guys, thanks for all the wiring advice...I'll get it redone.

The cointerra driver has now been merged into the cgminer git master code, so the lucky few who already have hardware can try it out by running their devices directly with a PC via USB. While there are probably fixes generically in the code from the main cgminer code, it is entirely possible there are still bugs in the driver code that will only show up only with real world testing.

I should add the cointerra device+protocol+driver has the most advanced work model designed for p2pool or similar networking and bitcoin transaction propagation with virtually seamless work restarts for rapid frequent block changes such as those required by p2pool, along with flushing of any queued work on a work template update such as that which occurs regularly with stratum update so it will always be working on the most current work - meaning it is optimised for maximum transmission of transactions, provided the pool is updating its work template frequently with new transactions. Kudos to the cointerra team for adopting everything I recommended in their work transmission/protocol.

Any idea why the local hashrate cgminer reports for these units is so different than what pools see?  Is it really just optimized for p2pool?  Even when the local console is claiming 1.7Thash the pools are reporting back 1.4x and it doesn't really seem pool dependent.

testerx -

a few ideas worth trying...

try a few different pools and see if you're still seeing the same issue, eg. eligius, etc.  when i looked, the cgminer reported perf was pretty close to the mining pool reported performance on my systems.

also, check you've got the two ac power cables attached to two different circuits in your home.  not just two different sockets.. make sure each socket is on a different breaker, to ensure you're getting all the power to the box that it needs (its drawing 2,000 watts which is too much for one single breaker)

and also what happens if you try selecting a slower hashing speed?  does it still have a disparity between cgminer reported perf and pool reported perf?

-- Jez

I'm on different breakers of course or I'd have triggered my circuit breakers!  It's showing the same 1.4xThash or so on multiple pools.  Eligius is reporting 1.48Thash over the last 3 hours whereas the control panel is claiming 1.7 at the moment (though it seems to be averaging close to 1.6).  Anyways I may need to try p2pool if the hashrate really syncs better with p2pool, maybe cointerra will save bitcoin from too much centralization by mining the best on p2pool lol.

I just got my tracking number for my two miners....should have them up and running tomorrow.

    Order #594
    Paid on AUG 23rd, 2013
    Received tracking on FEB 11th, 2014
    Received system on FEB 12th, 2014
    average hash rate 1st Miner - 1.6 TH/s
    average hash rate 2nd miner - 750 GH/s (only 1 chip operational ATM)
    power draw - approx 1900W each, based on readings from my "KILL A WATT"

I'm a bit disappointed that one of the chips in my 2nd box is not running.  But Peter responded to my text message immediately and we're troubleshooting the problem at this time.

After two hours...as you can see, one of my miners is only running a single chip

BTW - I installed a 70A 120V circuit breaker in my main breaker box and ran two 20A dual-plug outlets.  Each miner has each of its PSUs plugged into either outlet so that both miners are sharing both ciruits.  Each circuit should be good for 20A * 120V = 2400W.

Hey great news...When I was texting with Peter earlier, he said the beagleboards can be finicky and to try restarting...I tried three times and no-dice.  But I figured I'd try one more time before heading to bed and the fourth board came online...so I am now running full-steam-ahead :-)

The first one has settled in at 1620 GH/s
And the second one which I just brought online 10 minutes ago is currently hashing at 1550 GH/s

Bloody ASICS are worse than old cars!!!

Mine is slowly ramping up - 1594 and counting. C'MONNNNN!

[testerx]

Anybody getting a pool (other than p2pool) to get the same rate the local console reports?  Haven't had a chance to set up p2pool yet because of work but I may have to if it's the only way to get the full hashrate.  I'm seeing 1.45Thash on Eligius still with the pool showing the same number of accepted shares and everything.

[miahallen]

I'm seeing about 5% less on Eligius than reported in the console.  1540 on Eligius VS 1620 in the console.

That seems pretty normal.

Do I know you?

I just got my two TerraMiner IVs yesterday (early January batch).

if you don't mind me asking, what rough order number and date did you have for your Jan batch delivery, and how long did it take to go from "Shipping Preparation" to "Shipped"?

Back on topic a little, I think Cointerra deserves a little credit for what seems like a pretty clean shipment of December units (at least in the US - I would like to hear from customers outside the US too). By the sounds of it they shipped many people's units on Monday, and most units arrived at their destination on Wednesday (2 day UPS). Everyone's unit *appears* to be operating at 1.6 TH/s, 1.55 pool-side.

I believe I was late in the December queue, but received my unit yesterday (Wednesday, Feb. 12th). It took one day between "Preparing to ship" and "Shipping". It took 3 days in between the "Preparing to ship" and actually arriving. The big question is - are there any December orders that have not received their unit yet?

Don't know a single non US customer which has received a unit yet, regardless of order position

None of my clients have. Dec-Jan orders all around.

Someone I know got theirs in Canada yesterday. Hashing at 1.7 Thash and very loud apparently.

+1.  still more profitable to order 58nm antminers at this rate!
