Sorry people but its kinda easy to shutdown the miner without blowing things up

SSH into your box and then after login you type on the prompt

shutdown -H -P now and see how the machine stops running instant, this will protect it from running full power when turning it off

And yes do never turn on a electrical device instant after you turned it off.
Its a rule to give the components time to unload the power before powering it up again in most cases 15 seconds should do.
Since i close the miner in the proper way i do not believe blowups will happen since you have some time between shutting it down in the control panel and then goto the device to shutdown the psu. I my case thats about 2 minutes.

I had suddenly a die 0 problem and one of the asics was starting to turn off more and more cores on a die.
I had some back and forth mailing between knc and me, now they asked me to make a rma.
Just followed the steps and send the failing boards as they requested.
The next day knc reported to have fixed the issues and send them instant back to me
So in very short time the boards are back and hashing away.

KNC has prefectly solved this and fast.

So i am glad i did ask them for help, and instant did the RMA.

People saying it will take long ... NO ITS NOT it was lightning fast Cheesy

From the horses mouth to my ears.....
Thank you for sharing.

It's Friday 13th, time for something spooky:

https://hashfast.com/hashfast-announces-fastest-bitcoin-mining-chip-in-the-world/

500GH/s on a single chip.

And they expect to get more.

If they can get it up to 750GH/s (i.e. 3TH/s on 4 boards), they will have acheived now what KNC are promising 7 months from now  Grin

Sure nice improvments, they come quite late, though. Batch1 BJ customer have paid 50 btc for one unit long time ago. Just saying...
Q2 begins in 3 months, 2 weeks.... not seven months... and the ststement said q1/q2, so could be sooner.
I did hear good things about BA.... but HF?
no sense in exaggerating things... aren't they the same noobs that couldn't even secure substrates for their chips?
Until another company can physically show me a better deal.... They get a facepalm from my wallet.
and BTW... There's no such thing as a "perfect" first run in asic preorders.
You can expect BA & HF....and CT...to experience the same "Growing pains" as everyone else....
just like they've already shown. Anything else, and you're delusional.

Visit their sites, and you see statements like "TerraMiner IV is currently the most powerful, high-performance Bitcoin mining rig available for pre-order."(CT) NOT TRUE

and...  "HashFast Announces Fastest Bitcoin Mining Chip in the World!"...  uh huh...

because you will be putting your money garbage
innovate and be top company
but it was good to bring power supply and spent little energy

I would not be shocked to see Knc do another round of Jupiters that ship in January or February after Hashfast and/or Cointerra start shipping.

Why knc will leave the other companies take part of the cake?
And not continue production the 28 nm jupiter
Until the 20nm will be at production?

Neptunes are down to 32/1200 left up for sell.

Seems they will have sold out 1200 x 12,995.00 = WOW

as of now when I check is says 43/1200 left.

where are you getting 32 from?

Of course it could be 5.5TH and BTC could be at $2K by then, who knows, who knew that KnC's 350GH/s Jupiter would end up at 650GH/s and BTC up from $100 to $1000?

BTC price doesnt enter the equation. Yes, I used dollar pricing, but only because electricity is still billed in dollars and to make it more clear how relatively insignificant 0.1W/GH better efficiency still is and will be for a while. ROI calculations should be done in BTC, and any fluctuation in the price would apply equally to all asic vendors. If anything if BTC price keeps going up, the energy efficiency would become even less important.

As for Neptune being 5.5TH; thats possible, but for BA Im going by nominal specs, they also promise overclockability to 2.1 GHz which would put the X3 at 2.7TH or 5.4 TH for 2 units at the same price as Neptune. NOt too much difference there either, even if Neptune ends up at 5.5TH.

But I've made back what I spent on my Oct batch

When you calculate your ROI in BTC?

Sooner rather than later electricity costs are going to become very important.  Just how it was at the end of GPU and during FPGA stage.  All things equal then buying the lowest fab size will at least increase the resale value. 

On this note can you lower the voltage for the Jupiter's to increase the (GH/s)/W.  If so has anyone tried this and what were the results.

Good luck banking on BlackArrow.   I feel pretty confident that they will fold before releasing anything.  Too late to the party!

Why would they be too late, and Neptune would not? AFAIK, BA sold out. They should also be at least as close to tape out as Neptune, and without the risks involved in a brand new and quite radically different process node thats not even deployed.

Not saying Im banking on BA, Im not "banking" on any asic vendor, but if I were to make a bet, at least BA makes more sense to me. YMMV.

Seems they will have sold out 1200 x 12,995.00 = WOW

I dont quite understand that either. Even if people assume Neptune will do 4TH, BA prospero X3 would cost the same per TH and in all likelihood will be delivered  several months earlier.

Sure, Neptune might be more power efficient, but only if KnC delivers significantly better performance per watt than they claim and/or BA delivers worse performance per watt than they claim, because BA states 0.5 W per GH at the chip level (lets assume that works out to 0.7W at the wall) while KnC is saying 30% better than Jupiter. If Im not mistaken, Jupiter does around 1.1W/GH currently? A 30% improvement over that is ~0.8W. ON paper they are pretty much on par, with arguably BA having a slight advantage.

Even if you assume KnC will be one or two tenths of a watt more efficient per GH, if that is more important than mining several months earlier, then you are in trouble. @4000GH and $0.15/KWH, a 0.1W/GH better efficiency works out to 0.4KW * 0.15 = $0.06 per hour, or $43 per month. One day that will matter, but if that is significant next spring, and more significant than mining a few months earlier, good luck earning back those $13000.

1) The SeaSonic has two PCIe connectors one one cable.  Don't use two on one cable.   You should have 4 connectors plugged into the power supply itself (plus mother board and molex connectors).  That means you will have 8 PCIe connectors use only one from each pair.
That did the trick, thanks. The SeaSonic cable has 6 separate 12V lines coming out of 1 modular connector, which splits into 2 separate PCIe connectors with 3 12V lines each, so I had assumed it would be ok (the 12V lines are not shared). But apparently there is a power limiter in the individual output connectors coming from the PSU.

Figured it would be something like that.  Glad I could help.  Of course it helps that I had the exact same PSU and no problems.

Also I think KnC has been saying not to use the double plugs on pcie cables as well.

correct, albeit rather slyly after bitcoinorama claimed it would not/could not cause 'issues' on october boards.

around the same time as the 8 vs 4 VRMs debacle.

But I've made back what I spent on my Oct batch and managed to mine enough to buy a Nov batch, which has also paid itself off, and a Neptune and still have coins in the bank after paying the electricity, so for me thats all good Smiley

By the time KnC does a January or February batch HF will have been in full swing with 500Gh/s BJ's at $2250 and there is a likelyhood that Cointerra & Blackarrow will be shipping and selling their $6K 2TH miners.


the real question will be if BTC will crash with so many new miners just looking to recoup any of their costs or will most have strong hands (either true believers or so far in the hole why not go for broke)

I thought that swoon would happen this fall but only KNC and Bitfury came through...   if the new year brings a glut of miners, it will either crash terribly or hit $1500-2000 by April

Hashfest seems likely to ship within a month, if they don't have major setbacks.

I'm definitely hoping KNC opens up some more Gen2 Jupiter orders.
