Ok I can finally post! I've been lurking for a long time, gpu mining a year ago small scale. I just got one of the november jupiters I ordered and it fired right up working great. Avg hash rate in the interface is 660, but I'm getting an average of 10% hw errors. Seems way too high. I've been playing around with making the unit warmer (ambient temp is around 40) but all that did was cause a few of the vrms to have a "fault 4". Max temp on two of the asics was 70c. After resetting the machine and removing the covers that were keeping airflow down, it is still averaging 650-660 with 10% errors. There are only a few cores that get turned off and on occasionally. Never more than 15 cores off total across all the boards. Avg hashrate at my pool is showing near 600, which would be right for 660 - 10%.

Any ideas what I can do to improve it? Do I just need to wait for the knc tuning fw to be released for the Nov units?
Thanks!

BTW. After reading this board for a long time, and wading through all the bickering nonsense that trolls keep saying in this thread, KNC is obviously the only company doing the job right. I waited a long time to get involved in ASICs, but came close to ordering from BFL a few times. I'm glad I didn't. Maybe I would have received a unit by now, but it would be 50gh for about what I spent on each 660 gh jupiter. Cointerra is still a bust, hashfast is still a bust. Why don't the trolls and kids just get out of this thread and get a life Smiley  I thought I'd be getting 450-500 gh miners when I ordered them less than a month ago, instead I get 660 and it is a complete unit that fired up in less than five minutes after UPS came.  I'm thinking about selling one of these to purchase a Neptune (or two) because I have a strong feeling that KNC will deliver those on time in a few months, with a lot more power than advertised.

My orders started  in the 9900s, and started arriving today, tracking numbers received monday.

Neptune units for order are down to there are only 980/1500

I understand that the first batch of Jupiters had to make over 70 coins to break even in BTC and that was going to be tough...  but how can you look at a Neptune and say that it will produce less than 10 coins.    My two jupiters today still create 1 coin a day (combined).      The risk is very different than it was with purchasing Jupiters when BTC was at $100.  


unless you've got 2 November Jupiters pushing 700GH/s each I find it had to believe you can mine 1 BTC a day.

please explain how you're doing this if it's true.
or is it a mistake and you're calculations are incorrect.



I have less than 200gh pointed to slush right now, and I'm making .25btc/day. I have no doubt he's making 1btc/day.


All the profit calcs that i've tried tell me that at current diff 200gh will produce 0.1422 btc a day

*shrug*, variance and luck. I'm getting confirms of just over .01X btc/hr, as I have been for a couple weeks now. It'll lower in a few days, of course.

Right.  So OP's comment, while technically correct, was completely misleading.  His pool had a lucky string of days.  He will not make that day in/day out.

It certainly seems like some of you say intentionally misleading/inflammatory shit, in the hopes someone will call you out on it.  Then we get to have a multi-page, retarded debate on semantics.   Roll Eyes

Looks like the pool gods heard you.  Slow block turnover on Slush.

All November units arrived in a reasonable time and function as (or above) advertised.  Just like batch one.

Five stars KnC, really good stuff.

 Huh they still assembling and hopefully deliver until end of this week the Nov batch! toxic coffee in the morning?

nooooooo... I don't know if all the Nov units are out, but I think most of them must be.  My nov units were order #92xx, got them Friday (USA).

Slush hashrate up and return on blocks has dropped.  I'd say they're out and mining.

We've got a 106xx order and we still don't have a tracking code.  Does anyone know the latest order number to have shipped today?
Well someone with 101xx got their shipping details last night, so hopefully we are at 102xx or 103xx tonight.
103XX.   Have tracking number but it is NOT moving.   just says the label was made, not picked up yet.

WTF?  102XX and nothing.  I guess they are just shipping them out at random?

They are shipping by date of payment, not order number!

I know it's against tradition, but I've got another question that actually has something to do with a KNC miner!  Bertmod says that I'm only using 660 watts at the current levels. I haven't bothered to plug into my kill a watt yet, but why did I have to buy these 1300w power supplies again? Is there a whole lot more hash power available in these boxes?

Will Neptune have hosting or only sold as shipped units?

I've asked a number of times and so far they have not given any details or if they plan on offering hosted services.  I hope so,  got 4 neptunes and didn't want to run new circuits in my house but i will if i have to.


If you had $36k to spend on hardware for 4-6 months away you surely can get an electrician and throw some new lines in your home for you. People need to remember if they live in an area where it gets hot in the summer months it could be a big battle to keep things cool. Throwing just fans on it isn't going to cut it. Installing AC units also cost a fortune and eat electricity big time.



truth is if you are running 2 220v lines for your 2 neptunes you probably (unless central air and some new creative "duct work" to the asic room) you probably will need a pretty heavy duty a/c unit if window sized ..you guessed it 220v...so figure on 3 lines 220 for this to work imho

my 2c worth ( i suppose I could go to a gas stove and dryer and pull this off but with 100amps er...maybe not..have a brother with comercial space 12 miles away will prob go that route)

anyway my 2c worth

My boards run ice cold. I've got a proper environment for them. I actually had to block off all cooling to bring the board temps up into the 50c-70c range. Right now my asics are at 27, 35, 38, 22c.  Bitcoinorama specifically said we would need 1200w power supplies, that is a lot of potential capacity.

Yes.

And while we wait 6 months for the 20nm to land, the KnC mining farm is steadily increasing in hash power with 100% of the freshly made 28nm chips!

Remember - they loosley promised not to SELL any more batches until Neptune! Didn't say anything about mining themselves!

Fair play to the guys - they deserve the riches they most certainly are now amassing. They did a fantastic job with the 28nm

I seem to recall another promise that they wouldn't mine themselves with more than 5% of the hashpower they sold.

Do you suppose they're counting all the hashpower they've, uh, pre-sold with all these Neptune orders in that amount?

I do think it's odd that they ended the 28nm product line when it felt like they were just getting started.  I expected they would at least offer the bare chips for sale.

Good point Bogart - now i remember the same 5% promise being discussed but now i cannot find any reference to it.

If this is the case then these KnC guys are really something - i know if it were me i would be ordering 28nm chips by the ton!

Good point Bogart - now i remember the same 5% promise being discussed but now i cannot find any reference to it.

If this is the case then these KnC guys are really something - i know if it were me i would be ordering 28nm chips by the ton!

Brownie points to anyone who can find the quote Smiley

I know it's against tradition, but I've got another question that actually has something to do with a KNC miner!  Bertmod says that I'm only using 660 watts at the current levels. I haven't bothered to plug into my kill a watt yet, but why did I have to buy these 1300w power supplies again? Is there a whole lot more hash power available in these boxes?

Do what you like, however the higher wattage supplies are more efficient.

I have an APC BR1500G UPS then my Seasonic V1000 Power Supply on an older Jupiter -- it is about 7% more efficient and lower noise. So now I draw about 666 Watts as opposed to 712 previously. The Gold Plus rating means better regulation and typically lower noise.

So if you want a decent supply to handle a 660 GHash Jupiter -- then have a computer dealer read the 12 Volt specs very carefully and sell you a 1220 Watt or better supply.

Now expect 20 people to disagree and a long discourse -- but that is the scoop.

PS: Don't like your hash rate or HW errors? Just use the Shell to re-boot.

Give me this day my daily Bitcoin...

I did notice that the hw errors change significantly with some restarts. Anyone have an idea why? Seems like sometimes you get a good bootup and hw errors are only a few percent. Sometimes it starts up and hours later it is still 12%. Doesn't really make sense.

has knc stopped selling Jupiters ?

can only find link to Neptunes

Yes.

And while we wait 6 months for the 20nm to land, the KnC mining farm is steadily increasing in hash power with 100% of the freshly made 28nm chips!

Remember - they loosley promised not to SELL any more batches until Neptune! Didn't say anything about mining themselves!

Fair play to the guys - they deserve the riches they most certainly are now amassing. They did a fantastic job with the 28nm

so KNC has 70 percent of the current miner hash rate now or some such on the bitcoin network (on forums someplace) I think they said they would mine no more then 5% of the hashrate they produced? If my memory is correct ..that is a lot of bitcoin
