There has been no delay from what I've seen I've only ever known Marcus state production commences mid November and he's the guy in charge of production. Fact is PCBs were finalised and being produced at the time you were here which is mid Nov.

By delay I mean this:



turning into this:

fingers x'd you get your kit this week.

If that happens and all miners get shipped in November I promise you to apologize for being so negative about the "November shipping"
But I am being realistic and don't expect my miners to be shipped before December and that is why I am not as excited as you expect

Where is that screen capture from I've only ever seen it say November (and it still does on my screen)

That's Cyper's handiwork, it doesn't say that on site...

To be fair, my screen says "Jupiter November shipping - SOLD OUT"

Correct

I can only dream of the moment when ASIC manufacturers would advertise a November shipping and actually start shipping first half of the month.
These will be glorious times

Mine too.
I was just pointing out that November shipping will probably not happen for some people.
I hope I am wrong though

tl;dr: Plug your power supply cables directly into KnC modules to increase system efficiency.


Folks,

I was poking around the inside of a Saturn->Jupiter miner, measuring the 12V supply on the modules themselves.
With a supply voltage of 11.93V at the PSU, I was seeing 11.5V at the modules!

Examining things further, I noticed that the nice quality blue PCIe extension cables KnC supplied are only 20AWG (0.52mm^2).
This plus the resistance at the couplings is wasting a significant amount of power:

Module Power ~150W @ 11.5V = 13.04A (20AWG has rated ampacity of 11A in free air, btw)
Vcable=0.43V
Power loss in cable = 13.04A * 0.43V = ~5.6W

Plugging the PSU cables directly into the modules I measured around 11.85V. So:

150W / 11.85V = 12.66A
Vcable = 0.08V
Power loss in cable = 12.66A * 0.08V = ~1.0W.

So we have a percentage loss of:

100 * 5.6W / (150W + 5.6W) = 3.6% versus
100 * 1.0W / (150W + 1.0W) = 0.6%

When you consider how much a 3% increase in efficiency costs at the PSU level, the recommended course of action is obvious

*Thank you for this post. - confirming what some of us suspected... and removed those long ago....  but certainly still noteworthy to noobs & people who missed it...
Power counts significantly.

on a "related" matter... I noticed that my 65-75 temp range may not be the "Sweet-spot"..and I'm NOT suggesting anyone do this, but I noticed (using Bertmod) the output on the vrm's increases by a noticable rate... from 45-47amps to 50 plus amps OUTPUT per vrm when pushed to 80C.... So I'm testing them all at the moment...
Has anyone had the same result? I'm still waiting for pool results...

Tuning Suite any time soon?

Now with the team busy on the next production run any chance of us seeing it in the next few weeks?

'Orama please sir?

What is the potential of the suite? Got the gear in the garage now that its cold out, would love to start overclocking it while the weather is favorable. 

Joe it's pretty much ready, it's being tested to male sure range wise it's doesn't compromise your hardware and create RMA hell. As I said before it's a matter of days, not weeks!

WONDERFUL News thanks so much for the reply.

I'm being realistic, which is "having or showing a sensible and practical idea of what can be achieved or expected."

were you terrible at sports as a child??   I imagine you getting picked last in gym class everyday for some reason.....

No idea how you made a connection between my posts here and my sport achievements as a child 

  just playing armchair quack  -  chin up!!  you are on the winning team with KnC!

cash a BTC and go buy a nice watch or something  

Yes, I am happy being on the KNC team
I just don't understand how Bitcoinorama expects people to be optimistic/happy/excited about a delay  

There has been no delay from what I've seen I've only ever known Marcus state production commences mid November and he's the guy in charge of production. Fact is PCBs were finalised and being produced at the time you were here which is mid Nov, fingers x'd you get your kit this week.

I've only ever said production commences mid-November.

And just a word about delays, my UPS Shipped Modules arrived 3 days faster than my DHL shipped gear.

So even though they didn't get shipped the week they were supposed to, the net result was that because UPS was used they went from Sweden to me in the US 3 days faster

Some ASIC vendors actually learn from their mistakes.

Good job KNC!!

[demonmaestro]

Well some help that ya are.


Anyways Phoenix1969 got me set up.
I was having an issue with my miner dropping down to 60GH/s and the temps were around 50c. We looked and had 3 VRMs offline.. i turned off the fans to the case and blocked airflow for the heatsink to raise the tempature. Sure enough once it got to around 60c 3 VRMs were showing and then once it got to 68c it showed all 4 VRMs online and i was back hashing around 140GH/s. so these miners does not like being cold. I have tinkered with 0.98/0.98.1(beta)/0.99 with all the same luck. I am on the beta now.

Thanks again Phoenix1969 for the help.

Dear KNC,

I am greedy. Please sell me another Jupiter. Thanks.

Seriously, though, is there any idea when KNC will be accepting new oders? I don't care if I'm 2 months away from receiving something, I'd like to spend some of this BTC that's burning a hole in my wallet.

[jelin1984]

Is good firmware final the 0.98.1 beta or not?

[Searing]

Hey has there been any info about special deals for gen 1 /batch 1 buyers in the future?

I'm sure they promised us special consideration for buying the gen 1 stuff and getting this party started....any deals on future hardware offerings?

My Saturn has paid for itself 1.5x over and I want to get something more powerful.

Let's hear about some gen 2 hardware specials...maybe something in the 2TH range?

Or send us an email with a coupon....I'd probably jump on that even if it was a pre-order.

I'm sure they would tell us such if they had a clue ..my guess is they are looking at the landscape of what exactly to make at what PH and price and scratching their heads a lot...imho with bitcoin trending towards 1K a btc and the other mnfg out there....what should/could they shoot for? at 6PH unit in march/april at say 8K to over compensate for the dump of cointerra and blackarrow stuff?..they sure don't want to pull a BFL and say 900gh at 5K will work in jan/feb

yeah my guess is they are scratching their heads and pondering at this point (of course hope I'm wrong and the 20ph unit at 5k is coming out in march just saying)

[Searing]

you were referring to the tuning suite, right?

No, sorry...

All 1-500 customers will be receiving a free gen 2, 5TH machine

Cyper: Pessimist
Tigggger: Optimist

bet is JUPITER as an upgrade...kinda sorta pre-order Jan 15th 1000 bucks or some such (ducks hey don't throw stuff at me in chat) 

[rolling]

If anyone is looking to sell, I will buy any KNC equipment you have for 5 BTC per card.  20 BTC for Jupiter, 10 BTC for Saturn and 5 BTC for Mercury.  PM me.

If the blue cables are 20AWG do you have an explanation why PSU cables which are 18AWG get warmer, than the blue ones?
How did you establish they are 20AWG? Mine has no writing on them.

Here's a shot of the 20AWG marking (edge enhancement applied):

so these miners does not like being cold.

Since KNC is finished with this design, it would be great if they gave their reasoning for what flaw gets fixed when let to heat up.
There are plenty of boards that run fine at low temps (no cores/dies off) so it has to be a flaw somewhere on some boards.

[DPoS]

Is good firmware final the 0.98.1 beta or not?

I think until there is some tuning application added, 98.1 beta is pretty much the winner for most people

As long as bitcoin prices remain high, prices for mining equipment will go up not down.  Demand for mining equipment has skyrocketed because of high bitcoin prices.  Depressing but true.
