Topic: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s - page 32. (Read 231002 times)

That seems pretty normal.

Do I know you? 

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

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.

Bloody ASICS are worse than old cars!!!

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

NICE... like starting an old 57 chevy!

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

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.

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

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.

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.

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".

I am about done with a cointerra-monitor that should detect this and reboot your system.  This doesnt fix the problem but it should keep your hash rate up.

'Going' may involve a fire.  You really should do it right.  If there is a tin whiskers problem in that power supply you could easily burn your house down.

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.

imho.  should be running 220.  a 30 amp breaker with a server strip and c13 PSU plugs would do the trick for 2 easy

The waterblock+radiator setup appears to cool all the chips fairly evenly; though two waterblocks are attached to one radiator, the coolant flows through alternating radiator fins, so in effect they are cooled in parallel. For this reason I'm curious why my fourth unit is so much lower than the rest:



The second unit is approximately 5 GH/s slower, too.

Each wire could draw 70 A which would overheat the wire, melt the insulation and possibly start a fire.

The proper way to do what you want is to run properly sized wires from the 70A breaker (6 ga, I think but look it up) and put in a sub panel with individual breakers for the plugs you want to connect.

IANAE (I am not an electrician), but I did work for one during college.

I would like to know this too..

Yes, keep in mind that each "hot" should only be pulling a max of around 18A (2100W peak / 120V = 17.5A)

I figured this would be fine since most homes are run with 15A circuits and 14 gauge wire.
