Topic: CoinTerra announces its first ASIC - Hash-Rate greater than 500 GH/s - page 60. (Read 231016 times)

They didn't leave it running. Though it doesn't look like problems— it looks like they ran it there just for the demo.

It's very strange that no one has been able to product the working stats page from Eligius. This is a strong indication that there are problems and they are unable to leave the unit running.

Chip bring up and characterization, PCB and firmware tuning typically takes months. With a bitcoin miner Im sure that can be done faster, but what KnC did was exceptional and literally, an exception, not the rule. (The result was also a lot of DOA's and at least one customer seeing 100% failure/issue rate on a batch of 10 miners. Thats not what you want as a company). Also keep in mind how long it took Avalon, BFL, Bitfury how long it is taking HF and Bitmine.

If I were a customer, I would be disappointed that they are not only a few weeks behind schedule, but also still below target atm, but considering they received their first chips only 2 weeks ago, I wouldnt have expected miracles.

those guys are really dragging their feet, it doesnt take 2+ weeks with still no end in sight.  KNC did it in a few days, and any team with cointerra's experience on paper (if it is true) can easily do it in the same time. It's just trial and error unless they screwed up the design which i doubt.

Agreed!

I sure hope not, that would be a lot more work wouldn't it?

Maybe it's hardware tweak ^^

It takes about 10 days to decrease profitability by 20%
I agree with the notion that they should just settle for 1.6 and give us firmware updates as they tweak.  That makes good sense..

Well I'm hoping that once they've made whatever hardware level tweaks they feel they need to that they just ship it and then patch the firmware like KNC did to further optimize power draw.  I'd rather have 1.7thash in hand ASAP then wait for the perfect 2thash.  I doubt that this is am insurmountable issue, worst case they may have worse yields than anticipated but they can always just add more boards/chips in since the marginal cost is pretty minimal. 

That doesn't make any sense at all. Maybe they could get a 20% performance boost by changing the board, but why on earth would they delay for months when they could get devices in the hands of their customers.  I made way more money with my B2 Avalon then I have with my KnC Saturn, even though I got them just a few months apart.

If they have chips and aren't shipping, they must have some clearly fatal flaw. Either with the chips or the boards.

a previous screenshot showed they had plenty of asics so i doubt they're limited to the one prototype.. but since they're making tweaks to it, maybe they can't spare any to leave hashing right now... especially if they make improvements every day.   leaving it hashing serves no purpose at this time.. they're still in development... not yet in marketing mode... they're not trying to pacify existing customers... and they've stated they're not yet at their final performance numbers... so there is no reason at this time to leave a machine hashing (until they're done with the tweaking)

we have to assume that we're not just talking about firmware tweaks as if it was only that, they probably would've shipped it and done their updates in the field like knc did... albeit knc did release a second gen board that hashed 20% faster using the same asics as the 1st gen board so thats a very real example of the benefit of hardware and board improvements.. which their 2nd batch customers were happy to receive (different dc/dc converters) and their 1st batch customers missed out on.  my jupiters are batch 1 and hash between 450 and 550 gh.  the gen 2 models hash at around 650 i believe.  that 2nd gen board must be capable of improved power delivery.

presumably thats what cointerra is doing right now... as the chips already exist, and the cooling system seems over specced and both have been proven to work so the main board change they can make are improvements to power delivery.

So they only have one prototype?   That would mean that they may think hardware changes still have to be made..  if it was just firmware they would make a couple so you would get some 24 hour performance testing in

Also, that 1.62Th value is not pool side. Looks more like ~1.5Th.  But without any screen shots from the pool who knows


Sure, lots of other miner companies are terrible, but Cointerra was touted as the Gods and they didn't give a detailed engineering report on what they think the troubles are..   HashFast at least did that even though they were doomed to fail

expecting it to show up on the blockchain would require them to be hashing on that address for some time (hours to days) as eligius has a minimum threshold of btc earned before you receive any payments

similarly expecting that address to show up on the contributors list requires a minimum amount of hashing time (3 hours?)...

... so that tells us the machine was only hashing at that address for this demo and wasn't left on and continuously hashing, which makes sense given their stated goal of tweaking the performance.  presumably the tweaks involve both software (machine on, possibly hashing) and hardware tinkering (machine off, definitely not hashing)

also, they could be using a different address while doing their tweaks and they might only use the stated address when they want to demo it.

nevermind!

For the curious (since I was) their screenshot has the partial address '1CTtm4iiwqt35Rgew1DQW6YoSw', which does not show up on the blockchain or in Eligius' list of recent contributors.

yes, I'm actually pretty happy they seem to be reporting their progress on a weekly schedule (the past month seems to be every tuesday).   i like that they tell us what they're up to... and aren't making us wait an interminable amount of time to let us in on it.... and I'm pleased they make measurable steps forward with each update.  knc aside, compare that to most mining companies, who don't tell you whats going on, leaving you in the dark most of the time and waiting weeks or longer without an update.   yes, why not encourage this type of behaviour.   positive reinforcement might help other mining companies start doing similar..

But they still advertise with:

"The TerraMiner IV delivers unprecedented performance at more than 2 TH/s while maintaining an exceptionally efficient power rating"


but you treat them like 5 year olds & cheering best effort

oh yea!?  do you know ANY OTHER MINER that has EVER hashed that fast?  and they said they're making it go faster each day...  I'm happy to give them a few more days to see how much faster it goes..! (but id happily take it today at 1.6 TH)

Yes, it is great to see a working miner and Congratulations to Cointerra for reaching this milestone. Now we need to find out the actual system power draw from the wall to average 1.6 GH/s.

I apologize for being rude, if I was.  I am glad to see a machine together.
