Topic: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s - page 14. (Read 231002 times)

I am in a GB and we have 5 x Terraminer IV
We have had so many problem that our “colo owner, he wants the miners out”
Also we have a Terraminer IV at Cointerra repair center, no estimated ETA.

https://bitcointalk.org/index.php?topic=278460.400
My reading Terraminer IV is that they are very unreliable/UN stable, customer support does not respond and do not meet the sold hash rate
I would not recommend anyone buy a Terraminer IV
BUY another brand -- get you money back before it to late

Or is you still believe these are ok then buy a 3 week old miner of this GB for cheap as we are in process of voting to dispose of all 5 miners

It is crappy because I paid for 2THs machine and received 1.6THs. It does not matter what time frame it took or if any other products are available etc. I did not get what I paid for and that's why I call it crappy.

I don't care what percentage of Bitcoin network CT miners run because it means nothing to me and my money.

At the end of the day, I am short 20% and that whole 20% is supposed to be my income for the amount and efforts invested.

the firmware updates have eeked out a bit more performance, especially in some people's systems (the ones that were under performing)... and have been much more stable...  however, the new prototype box thats hashing at 2 TH/s is completely new boards with 100% new components, and new power supplies.. thus almost everything inside the old box is completely new in the new version, thus there's nothing much to upgrade.. its pretty much a new box with nothing common from the old one except the beaglebone and some wires.  that probably explains why it took a bit of time to get working, and also explains why they can't just rush it through production because the supply chain of components isn't the same so needs to be sourced from somewhere.   it is, however, the same identical asics.. so that bit is good news.. their asics did indeed hash at 500 GH/s, as they always claimed.  just not with the board or power supplies that their subcontractor had designed for their initial system... thus back to the drawing board for everything else.   pretty much the same story with KncMiner as well.. and, for that matter hashfast.  these guys all shipped systems that were then upgraded with noticeable performance improvements when they had the time to redesign their boards (probably in all three cases it was about delivering more power to the asics via optimised dc/dc circuit design).

From all I read on the forum is its just luck if you get support.  The general public with them will not take them apart in fear of warranty esp since many still believe they are going to get the 2TH upgrade in firmware that is never coming.  Iirc it was you and a few others that were told that its hardware limitations on all units in the wild.  With the Dragon Miners and clones they are not promised 1.3TH turbo mode and things like bitmine.  The chips are capable of doing so but the hardware is not.  I'm running one of the original 5 blade 40 chip boards at 1.2TH right now, but all the new ones are 4 blade 32 chip and run at 1TH.  I know some have issues with theirs and I've been lucky with 4 so far and my 5th gets here in a few hours so knock on wood lol.  But same with CT, HF, KNC, etc. many came in with major issues (some due to shipping some not though).

I do understand you have a large amount of CT hardware and you for the most part stand behind them.  I won't blame you because I would do the same and I also know you will admit when something just isn't right so I hope this does not come off as an attack against you.

I still would buy at CT but even at 6k it is not worth it to me.  I am lucky like some because if I did and it broke if I got no response I can just show up to Austin.  Spend plenty of time there for cars and friends (plus I live in Houston).  So can't ignore the box left at front door if they aren't there with "Please fix! <3"!  Lol

Their a lot out their on the forum  but the ones I've seen so far

just out of interest is this the one you're referring to or can you point me to a better option (as this one is more expensive, and a pretty bulky box.. and they say they only have one left)

dunno..  definitely not clear cut.   all i heard about the a1 chips was speculation about who owns the rights to the a1 chip as bitmine seem to claim some sort of exclusivity or design rights, which of course may be them making false claims, and then plenty of chinese clone companies using them - possibly without permission (do we know yet?  has anyone figured out who really owns it?)    and i still see a lot of angry a1 chip customers waiting for their promised systems.  which also under perform, compared to their claims.  no turbo mode, for instance...

this isn't as clear as you make out with your 'do the math' statement.   also, cointerra at least has a customer support department and can be reached by phone and email.  sure, they're snowed under so sometimes take awhile to respond, but at least they employ a customer service department (10+ people).  i know i can call when i need something.. or email.  i wouldn't know where to start to call a faceless anonymous chinese company, nor would i expect much support.

Not to mention that the Chinese A1 use less power.  CT = 2000w for 1.6TH? Vs 2200W for 2TH?

I hate to say at this point people are paying for a name but there is no support so about the same for the Chinese miners well actually I can contact them for questions and not just leave voicemails.

In this industry to me a name doesn't mean crap.  Now for example the automotive performance industry ... I pay more to buy let's say TiAL wastegates/blow off valves/etc vs the cheap copies made and sold by eBay and some shops.  I do this because hands down the quality is better, there is support, etc.  and yes I know a lot is outsourced but even then there is quality out sourcing vs make cheap as possible.  When it comes to bitcoin it doesn't make damn bit of difference.  Products are worthless in less than 6 months usually so why worry about longevity lol!

How about the 1 Th/s A1 chips setup from china they are going for $3000 so yes CT offers crappy Hashrate = cash  , Hence 1.6 Th/s = 6000 + shipping ($589) and China 1Th/s with shipping included is $3000 hmmm u do the math.

ok, im going to argue with you on one point.  how, do you argue that its a crappy hashrate?  can you buy better in the same timeframe?  better not just in terms of delivery date, but also in density.  Sure, you can have 9 or 10 antminers that achieve the same hashrate but they consume a lot more power and space, and will cost more to run.  they may be cheaper now, but at the time they were more expensive too.

ive now taken delivery of quite a few cointerra systems since they started shipping (tens of systems).  i havnt been able to buy better.   even if their hashrate was 20% down on what it was sposed to be, its still quite a bit less expensive than the other options i had available to me at the time.  i paid a lot more for my hashfast gear and much much more for my kncminer gear.   and even now, pre-ordering a knc neptune with an unknown delivery date still costs more in $/gh than buying a cointerra today that has reliable and predictable delivery dates (right now theyve caught up their backlog and are delivering on the month theyre sposed to for each batch).  their latest release oif a few days ago confirms theyre already powering 10% of the bitcoin networks, which if you do the math means theyve shipped thousands of the boxes to achieve that %.

cant argue with the low price of bitcoins argument and right now ive been buying bitcoins but thats not a cointerra specific issue, thats simply a 'do i buy bitcoins or mine them' issue... but if you choose to mine, i think its hard to find any 'currently shipping' options that are a better option.  and yes, im somewhat biassed.  but also, since i own a bunch of kncminer, and a lot of hashfast gear, and even more of cointerra gear... ive at least some 1st hand knowledge of the options on the table.

OMG, that's nice to hear that they did refund the money~ With the crappy hashrate and low price of Bitcoins, its going to be refund central at CT!

I bought 3 units but decided to ask for a refund as soon as the performance specs came out.  It took 30 days (which they stated was the limit at the beginning).  To their credit, they did come through

i asked for a refund. lets see whats next.

the webshop says order "processing", so maybe its already too late.

same boat bruh, they almost threw a refund at me when i asked for an April update.

now im starting to think its the only choice that makes any sense... but then hardware in 2 weeks sounds so tempting...even hardware that only runs at 75% its original power....

some communication from CT would be nice

Did anybody actually get a refund?  I've been reading horror stories about it taking over a month for a refund and with the news that the April batch isn't going to hit 2Thash it makes no sense to keep my order (there's cheaper hardware out there and the price of BTC keeps dropping so I'm not sure I can ever ROI with this batch). 

It is the same deal for April batches.  They have a new board revision that will apparently bring the hashrate up, but this would be for the May batch at the earliest.

Whats the current Refund-Situation at Cointerra?

Same here the newer FW is buggy less hashrate and also the temp threshold is lower per chip which now is the AC room causes 1 board to stop working , downgraded to 6.48 and things are not faster but stable

Good to know I'm not crazy. Thanks for your feedback. Con did mainly aesthetic hashrate reporting changes as far as I could see, but it was a very superficial look.

Same here. I've to downgrade to 0.6.48, cause with 0.7.6 hashrate is about 10% lower, at least on P2Pool.
