Not Cool.
Also I paid BTC4.5 for 50GH of mining, NOT for a percentage of the unit. (Yes i paid the original asking price of BTC4.5 before you dropped the price) I paid for 50GH with a 3% fee and I'm getting 40GH/s at 10x the advertised fee.....

If the difficulty goes up at the current rate and if BTC/USD goes down much more are you going to ask us to pay you for the electricity bill?
Can you provide proof you pay 31 cents per kw/h? Seems expensive.

Sadly, it's not a mistake.  Undecided


I'm doing payouts the same as I have been doing my KnCMiners - basically my only fee is electricity since the initial 3% fee won't 'cover it. (Why? Cointerra promised one thing [power consumption], delivered another, just like KnC)

So at ~2900W 24/7 @ 31cents kw we're at about ~$620/month just to power 1 TerraMiner.

So each bi-weekly payout, each miner will have a ~$300 fee (Again, this is literally what is required to power the unit each month). *Note this comes out to about a 5/6% fee instead of the original 3%.


Miner no. 2:

one week mining: 1.38932488 btc
one week power: 151$ =  ~0.26 btc (bitstamp: 575$/btc)

profit: 1.39 - 0.26 = ~1.13 btc
profit - your 3% profit: 1.13 * 0.97 = ~1.09btc

For 40 shares - I should have ~0,548 btc, and I have only ~0.444 btc...

Waldo, could you explain this difference, please (who has made a mistake: you or me)

First, I apologize to everyone for my not perfect English, but I think what I am going to write will be understood ...

dear Waldo and other members of the GB,
I'm sorry to write in these terms, but I want to be direct and honest ... but really do not understand three things:

1) the first, as it is possible that the OUR miner consumption is 2900 W at wall outlet? it is practically impossible at electrical and electronics level,
 all users who have read here and on the forums Cointerra to declare a maximum of 2,000 w to 1.62 Ths (a user even w 1800) ... it is virtually impossible that we consume so much with two PSU 1100 W (two PFE1100, maximum 2200 2300W off-specification limit, see the links at the end of post).

http://Forum.cointerra.com/threads/post-your-terraminer-iv-results-stats.385 /

http://Forum.cointerra.com/threads/how-many-watts-does-the-2th-use.186 /

2) regarding the cost of electricity, considering you're in the state of California, and you should (and here I use the conditional) you should use a contract mall, I think 0.20 cents per KWh is definitely more correct of 0.30 indicated ( I do not want to tell you that you are not correct, I just want to point this thing ..)

then according to my calculations (assuming realistically 2 kWh x 0.20 x 24 h we have a consumption of about 9.6 dollars a day, which are $ 288 a month ... I would like to understand why the X2 spending on electricity. waldo .. ... please , Can ypu clarify this crucial point, or all of us ?)

as regards the value of each share now we have a fact that have been undersized from 25Ghs to 20Ghs, but we know on that, at this point there is nothing to do .....

I hope to get some answers from you Waldo, especially on the issue of the absurd consumption of ns. Terraminer  ......

from http://cointerra.com/faq/

"What is the specification of the power supplies in the TerraMiner?


The TerraMiner Has Two Power-One 80 PLUS certified "Platinum" efficiency power supplies. They have a wide input voltage range of 90-264 VAC. The normal operational range is 100v to 240v, I know it will work at all on the standard voltages around the world (110v, 120v, 220v, 230v and 240v). The datasheet for the power supplies can be found here. "...

http://www.power-one.com/sites/power-one.com/files/documents/power/datasheet/bcd.00012_ai_pfe1100-12-054xa.pdf

3) Waldo then a third point, very importantly, continue to refer to + 30% as if it were reportedly scheduled to consumption of 2100 W, but I want to make you see that means that it is more by 30% compared to 1600 W (! (and therefore a total 2000 w 2100 w NOT an absurd 2900W)


from the site of Cointerra Dateline 21/01/2014

"Our production lines are assembling units and we have Stumbleupon for certification simultaneously. The production units That We have assembled and tested so far are running at between 1.63TH / s and 1.72TH / s with power draw at the wall between 1900W and 2100W - Typically 20% higher than our anticipated target of 1650W but still sufficient to operate in a typical U.S. home (110V) plugged into two outlets on separate circuits 15A, or in a typical European home (230V) on a single circuit. "

bye,

Yes the amount taken out of the first 8 days seems high, it's unfortunate that the price of BTC during payouts was ~$511 (check for yourself) and it was NOT the current $575 (so please stop acting like it was).



OK, Waldo, first thing, correction is coming:

Miner no. 2:
one week mining: 1.38932488 btc
one week + one day (??) power: 172$ =  ~0.338 btc (511$/btc)

profit: 1.39 - 0.338 = ~1.051 btc
profit - your 3% profit: 1.051 * 0.97 = ~1.02btc

For 40 shares - I should have ~0,51 btc, and I have only ~0.444 btc...

So, it seems you could still explain, who has made a mistake: you or me...





Second thing:

Everyone says, that Terraminer draws about 2kW power, and you are trying to convince that these particular you have received - suddenly draw 150% of every normal Terraminer. So I decided to ask Soniq (from other Cointerra GB), and let's see how he answered:

"Me: Soniq, do you know power consumption of Terraminer #1?
Soniq: 8.5 amps"
https://bitcointalk.org/index.php?topic=278460.msg5422641#msg5422641

P = U * I = 230V * 8.5A = 1955 VA (actually: Watt)

Tell us, why Soniq lies in such matter...



Third thing:

http://www.eia.gov/electricity/monthly/epm_table_grapher.cfm?t=epmt_5_6_a
33.69 cents/kWh is Hawaii price - so please confirm here that our Terraminers are placed in Hawaii.

here you have Sy from Germany 0,253€/KWh (0,329 $/kWh) - and he probably won this small world
competition for most expensive energy. (you are trying to convince us, that US citizens have more expensive
energy than EU citizens)
https://litecointalk.org/index.php?topic=4300.msg30129#msg30129


Proof of my kwh rate has already been proven in my KnCMiner thread- I can try to dig it up again


Yes, in such circumstances please do it again...
And maybe it's a really good time for change your energy provider, maybe for even two times cheaper, who knows...
(I'm very surprised you didn't change most expensive US energy provider until now)



So, in such circumstances - maybe a little bit closer to the truth is such calculation below:

Miner no. 2:
one week mining: 1.38932488 btc
one week power: 2kW * 24h * 7d * 0,20$ = 67$ =  ~0.131 btc (511$/btc)

profit: 1.39 - 0.131 = 1.257 btc
profit - your 3% profit: 1.257 * 0.97 = 1.22btc

For 40 shares, maybe ~0.61 btc, not ~0.444 btc...



So please stop acting like it was, if you really care about your reputation on BitcoinTalk.org

You are not the only one impacted by Cointerra late delivery. Not the only - disappointed by small profits.
You could propose flat rate (not 3%) at the beginning - just to avoid such falling profits


P.S. sorry for my "english"

ref.2 http://en.wikipedia.org/wiki/Electricity_pricing#Price_comparison

Ok, you're mad at me because Cointerra underdelivered? - its out of my hands, dude. They are working on firmwares to fix this. You are getting an EVEN percentage like everyone else.

3% fee was assumed due to the CLAIMED power consumption that Cointerra stated. They are using over 30% of what they claimed to draw. Fees need to be adjusted to suite that.

Yes the amount taken out of the first 8 days seems high, it's unfortunate that the price of BTC during payouts was ~$511 (check for yourself) and it was NOT the current $575 (so please stop acting like it was).

I'll adjust next weeks fees to reflect any overpaid fee on the first week.

Proof of my kwh rate has already been proven in my KnCMiner thread- I can try to dig it up again, but like I stated, I've already proven it and posted it online.

That answers everything.

Again, there is no 3% fee- the ONLY fee is electricity to keep the miners on - everything else is free.

No, Dude. You advertised 50GH/s with a 3% hosting fee.
At no point did you say, 'plus electricity fees at the current USD rate'

The technical specs on cointerra website say Nominal power consumption is 1650W, and that it's supplied with 2 x 1100W PSU's, so how the freaking hell can it possibly be drawing 2900W ??

Revilo, I'm sure if the Terraminer would in reality 2.2TH - you will ask about your 55 GH/s, not 50 GH/s.
So don't insist for this matter - there are others mentioned, more important.

Hopefully this explains a bit to answer the above:

- Next payout I will be subtracting ฿.1 ($50)/miner in fees to address the overpay in fees from this week. This means your next dividend payout will have the BTC that was missed on the first round.

- I was mistaken about .31 KwH, it's actually .30 KwH. http://imgur.com/dcGywPf

- I was also mistaken about 2900W, it's closer to ~2800W w fluctuation spikes up to 2900W. http://imgur.com/H0B6sld and http://youtu.be/uvVCISb9N14
*Note I'm only measuring half the power consumption with the meter.

- .30c @ 24/7 still, has about $300 in fees per bi-weekly payout per miner. That is literally what it costs to run the machine.. not including cooling and maintenance.


I know that is not ideal, obviously. We're hashing at 25% less than what we should be and using a crazy amount of power. All we can do at this point is wait for firmwares from Cointerra.

Cheers
WH
Dear waldo , i guess it's best if you get another power meter.
from my previous experience with server PSUs , they have something called PMU , which is abbreviated for Power Management Unit .
PSUs can work in active-active/active-passive , they can work in 20% - 90% capacity and so on.
so measuring one PSU and assuming that it consumes twice the amount can be wrong .
and the reason to do so is that , usually PSUs yield better efficiency in loads greater than 70%.

See for all KNCminer shareholders, when Jupiter hashrate was much bigger than announced earlier.
Yes, you would stay stable as rock at first, low hashrate - while rest of shareholders is sharing the extra hashrate gift from KNC.

- I was mistaken about .31 KwH, it's actually .30 KwH. http://imgur.com/dcGywPf

Did you try to find better offer (if I good remember the US energy market is deregulated, especially in comparision to UE market)

*Note I'm only measuring half the power consumption with the meter.

If everyone else in the world measures Terraminer and gets only ~2kW - the quite probable explanation,
that your kill-a-watt works improperly. Could you have some multimeter for a while
(e.g. http://img.directindustry.com/images_di/photo-g/analog-power-meters-5231-5940213.jpg
http://techchannel.radioshack.com/measure-amps-watts-multimeter-1243.html )

1390W and 120V (US standard) - it gives ~11,58A for one circuit,
Check current value - you should have rather something similar to Soniq 8,5A...


If not - we have some really crappy Terraminers, and I think this should be documented
and send to Cointerra - just to receive yet another recompensation:
for 150% power consumption in comparision to other Terraminers.

Jesus Christ man!  Where do you live?  That power rate is insane.  My power rate is between $0.07 and $0.08 per KWH.  If I had the space, and spare power capacity, to host these, I would tell you to send them to me.

As far as rates, I'm actually looking at office/warehouse space for personal reasons but if the bill fits, I'll relocate miners to this location (which will reduce my kwh rate and your guys's fees). This is not a promise at all since like I stated this is mainly for personal/unrelated business but if I can lower the rates, that would be a win-win.
Well, the fact that almost everyone uses the same meter (and the fact that it reads fine on every other device) leads me to believe it's working fine. I do have another one on its way on to measure both PSUs simultaneously, though.


Hi, Waldo

Still are there any chances for a new location? (with lower energy rates, we hope...)
Did you measure both PSU simultaneously?

I remember Miner 2 was working at average 1,6TH/s first, now it is a bit lower, about 1,4TH/s, we can see this in chart yet.
http://eligius.st/~wizkid057/newstats/userstats.php/12ndhaAT4Pbv3gNDZNg3PUiUGG16PB2sGr

I've been working with their support and it could be due to the new firmware that they have me on. The machines are quite finicky with setting adjustments- You can reboot it and it will hang, another reboot and it won't save settings etc. I've done 2 reboots today on all machines, temps are good. I may monitor the stats a bit more and compare them to the older ones. Eligius has been having some minor stats issues this week so I'm not sure if that adds to it as well.

Thanks for the update Smiley

Bad news! Sad

It looks like TerraMiner #3 is dead.

I haven't checked the stats in about a day or so and when I did I noticed Miner #3 not mining.

Tried to log in via ssh nada, tried to log in via http nada.

Ok- manually rebooted.

No lights but PSU fires.

Swapped power cables and tried again.

Same thing- fans turn on but no LEDS or access via browser.

Swapped cables with a working miner (and swapped outlets that I was plugging into just to verify) - still nothing.

Emailing Cointerra for a support now hopefully they can give us some tips to get it working so we do not have to RMA this =\.

I will keep you guys posted once I receive a reply from CT.


Thanks for the update WH, hopefully they pay for the RMA but if not we will have to divided the cost.
THanks again Smiley
