damnit knc, why did you have to remove ports 5 & 6 from the Nov Jups. 

Some of the Oct Jupiters were shipped with only 4 ports as well. Not really fair for those that planned to upgrade them.

$2 in parts, a little soldering skills....

Neptunes are still very much in the preliminary design phase.

 Ugh. This statement does not inspire confidence for shipping Neptunes by end of Q1

Q1 was never a possibility. Ever.

My October Jupiter hashes at 425Gh/s (has the Die0) issue.   I've wasted so much time (and downtime) messing around with it I've given up.

Any Toronto-based Jupiter miners interested in some pocket scratch in exchange for coming in to get mine up to speed?

After I did what it said in the post that was on KNC's website, my father's DIE came back alive and he's now hasing %100. Here is the link:

http://forum.kncminer.com/forum/main-category/main-forum/24988-0-99-tuning-suite-instructions-october-miners

Thanks!   I tried messing with that a few times and it killed more dies.   I'll give it another whirl!

Just be very careful with this step:
4. If increasing the SPI voltage by itself does not fix your issue, increase the voltage on each affected die, this should then bring the die back to life (it is best to not change the voltage on any working die)

Keep a close eye on the current and make sure it doesn't go above 60A. To be safe, try to keep it in the range 40 - 50A.

I found that adjusting the voltage of one of my dies to around -0.025v gave me 58A! If I'd kept going to 0 or up into the positive numbers, I'd probably have blown it all to shit.

Every miner is different, I have seen guys with settings of +0.8v etc, but keep a close eye on the values on your particular machine.

Why there is no such warning in that "official" post I have no idea. knc really should warn people that the settings are wide enough to do real damage to their hardware and what to look out for to avoid that.


Edit: Yeah, this has been annoying me:

Present, stable:


Adjusted to -0.025v (my mistake, 57A, not 58A as I said)


What exactly would happened if I set it to the full +0.1458?

@bitcoinorama And so... when will they put up for sale the update modules? next week? price? Payment will only be possible in bitcoins? And finally... only for the old costumers

They can't, at this point, hold it to just original customers as they advertise it on their website for all products. Originally it was just for Mercury and Saturn, but then they openly decided to let anyone buy them, customer or not.

Neptunes are still very much in the preliminary design phase.

 Ugh. This statement does not inspire confidence for shipping Neptunes by end of Q1

That was never a possibility in all reality, especially with how long it takes to send to the foundry and then get it back ... at this point, April would be the earliest.. I believe my wager from 2 months ago was mid April for earliest, with mid May being most likely. And by then.. good luck ever getting a 15th of the BTC price back.

I am really starting to wonder if they might have produced a batch of Jupiters and decided to just keep them to mine privately. Despite their 28nm competitors lack of delivery, the network has still managed to grow rapidly and there is an obvious demand for their already designed and successful Jupiter miner. They even told us to get some BTC ready and implied they would sell from stock instead of taking pre-orders which was followed by complete silence while somebody very steadily added a lot of hashrate to the network. If they were able to manufacture another batch of Jupiters using the proceeds from the first 2 batches they would be foolish to sell them if they believe they would turn a profit.

Some of us were aware of the hidden 55nm competition coming online during December.. some of us said things, and we were ignored and laughed at. They're going to keep shipping, non stop.

And when Cointerra starts shipping in the next 2 weeks it's going to hurt more, but what would be worse is if they have planned things out to the point where they have enough material to fulfill their first 2 or 3 batches. Their assembly line makes KNC's look like a 15th century sheep farm. They could knock the batches out in a week, maybe 2. Someone correct me if I'm wrong, but they were doing 5,000 and 10,000 unit batches, and still are, with some single orders in the upper hundreds of units.

Imagine that difficulty level.

This doesn't catch KNC off guard, nor any other serious OEM. Everyone knows it's going industrial which is why a lot of these initial designs are very industrial, to prepare them to move to the corporate level.

[RoadStress]

The only thing for certain - the guys who pre-ordered knobtunes are going to get a few grey hairs this summer

I missed you Welcome back.

[smoothrunnings]

I can't wait for the next generation chips.. 14nm.

There are apparently two manufactures in the world who can make 14nm dyes, just no one is making a 14nm ASIC chip yet.

I hope they don't go for to much perfection with the Neptunes...  This still is an arms race and difficulty

rising exponentially is still a big part of mining.  no..?

bottleneck with controller boards that's the simplest component of the whole miner.  Could you

please explain Orama..?  I'm not sure I'm believing this unless you/KNC can explain with more detail.  KNC have

pulled miracles in the past with bigger volumes and now there's a bottleneck.  I'm sure another PCB

manufacturers that can make it happen if existing manufacturer is busy. 

Also. didn't KNC tell us to keep BTC handy for these Jupiters.  What's changed..?  Fear of Neptune refunds..? 

by the way they sold out this shouldn't be the case.

Come on, we're all men here.. spill the beans even if some will get upset I'm sure we'll get over it. 

I'm guessing the BBB (BeagleBoneBlack) could be a bottleneck.

Cointerra is using them too, and probably many others, because of the 'powerfulness' of a BBB compared to a raspberryPi.

<Conspiracy mode>

BeagleBone is a US (non-profit)company/foundation, and rPi is from the UK:
Hopefully Cointerra (US company) didn't sign an exclusive deal with BBB, for a certain amount of time/products.

Years back Ipads were available and way too expensive for my budget.  I watched closely for reviews of the tablets coming out of Asia.  There was a write up on the Cortex A8 that sounded very good.  Then Merrimobiles offered the Mid816 with the Cortex A8 at a reasonable price.  I still use it as my goto tablet tho I have one newer and three e-readers.  That Cortex A8 is the reason for choosing the BBB.

...

@ 'Orama/KnC: Could sales of a Jupiter with controllerboard minus BBB be an option ?

if the beaglebone was the bottleneck I'm sure he would of said just that...
There's more (or less) to it they're not revealing.  This seems a bit smelly also.

Perhaps something to do with the FPGA on the controller board interacting with the BBB.

I was aware of Avalon's claim that they would be producing 2Ph/s worth of gen2 chips per month but after their failed auction and over priced reels in their store I guess I didn't believe they would be hitting the network so soon. I guess it is extremely likely that the recent hashrate is from Bitfury and Avalon gen2 chips...

Was KNC offering a refund for first batch Neptunes?

[Tehfiend]

Was KNC offering a refund for first batch Neptunes?

Yes, up until the time your order "enters production"...

[psjw4450]

I wonder if its best at this point to just get a refund.  Were they offering bitcoin refunds or USD.

Oh god, not this again!  Of course, USD only.

[psjw4450]

Has anyone reported any successful refund requests. 

[Tehfiend]

Has anyone reported any successful refund requests. 

Yes, I know Phoenix and several others have received refunds...

[ASIC-K]

yup, screw it. im getting a refund. knc just keeps disappointing me.

Can ports be soldered into the November batch Jupiter's to be able to add upgrade boards?

[padrino]

A number of folks have done it without issue..

[ElGabo]

I had a big trust in KNC but now I'm thinking on a refund too...

If Neptunes will late, they should sell Jupiters for existing customers asap.

Thats what I call customer protection not upgrade modules...

[helmax]

Neptunes are still very much in the preliminary design phase..

serious? so why ask our money!!!

jupiter bad firmware
many die 0
many errors HW
ask people PSU 1200w only spend 660w

and now have 34 millions dollars only for say preliminary design phase is joke?
