That sucks.  As the fastest and cheapest solution, I would recommend that you or a nerd friend repair the board by desoldering the burnt connector, and soldering in two connectors on short leads to replace it.

I recently bought these here cables with the idea of cutting them and using the male (I think) ends for that purpose:

Well it has finally happened. The first time the pci-e cable melted on the psu and I was able to avoid RMA.

This time the connector on the cube fried. One of the 6 pins is completely black and it won't power up anymore.

Sent support/rma request.

Your request (35659) has been received and is being reviewed by our support staff.

I know KNC does not work on weekends. Will keep this thread updated with procedure and responses.

EDIT: The cables used are the stock cables that come with the Seasonic x-1050. These cables are 16AWG and state they are High Current on the box.

UPDATE:


1. November 1, 2014 (Saturday) Sent KNC support email informing them of the burnt connector and asking for official guidance/procedure. Request #35659

2. November 3, 2014 I got an email from KNC this morning. I have responded with the picture that has been uploaded in the OP.

Dear Marc,
We had already shipped PCI-e cables.
We are really sorry to hear about what happed and are going to grant you with RMA to replace the connector for you as soon as possible.
Could you please send us the picture of the connector that is burnt?
Thank you.

Best regards |

3. November 4, 2014 I received an update this morning. I have been authorized for an RMA. HOWEVER I must pay shipping the cube back to KNC. From Canada it costs ~$300 via FEDEX or UPS. Canadapost $150. I am disappointed that I should be responsible for paying shipping when this is a known defect with the Titan. I have asked, politely, that KNC provide me a return shipping label given the fact that this is a design flaw and no Y cable was provided as of yet. I am also worried about taxes on the way back. Since they are asking me to declare a value of $400USD I infer that they will in turn declare a non zero value when they return the fixed cube. That means I will have to pay another 15% of taxes on something I already own.

Hi,
We can at this stage offer you an RMA.
Please put RMA-T141104-01 in large writing on the box and send the cube back to the following address:
KnCMiner
Birger Jarlsgatan 33
11145 Stockholm
Sweden
We will review the cause of the issue and get back to you as soon as possible with a replacement or a repaired cube.
Please note that the shipment to us will need to be paid by the customer and we will pay for the return shipment. You should declare the value per cube at 400 USD.
Thank you,
Med vänlig hälsning | Best regards

4. November 4, 2014 I found a cheaper option with CandaPost. 4 business days guaranteed service to Sweden. This was their cheapest option other the economy surface which has an estimated 4-6 week delivery standard. I have since paid myself for this label and have modified my request to KNC from providing return label to providing a reimbursement for $95.34CAD which is the cost of the shipping.

You forgot about the huge world wide demand for Y-cables, spanning almost each industry.
/sarcasm off

Issue with the supplier means: the supplier cannot produce enough to cover you, too, in the next time.
Datorhall first, you know.

Hi,

Due to an issue with the supplier of the Y cables we were not able to include them in the latest shipments. However they will be sent to all customers who did not received them with the Titan, separately as soon as we receive more from our supplier.

I wonder what that 'issue' might be?

A multimillion-dollar company almost entirely funded by the goodwill of its customers decides to treat them like idiots and force onto them a unit which does not conform to the original product description (it cannot hash on all scrypt applications, it will only work on particular pools) while repeatedly shouting "nonrefundable!", can't organise themselves a simple order of 'Y' cables without issues arising?

It would be hilarious if it weren't so tragic a lesson in abuse of trust.

I received my Titan today.  So far it seems to be running OK.  No fires yet.

The only hiccup happened (I think) because when I first tried it I only connected one cube.  Then later when I connected them all, it somehow remembered that only one was connected before, and that was all it detected.  After clicking "reset to factory defaults" in the web UI, and then re-entering the pool settings, it then detected all four cubes.

It came with firmware 1.05.  I'm mining on litecoinpool.com, which it seems to get along with.  I haven't tried any other pools.

I'm powering it with two Corsair HX850s, and have it clocked at 300MHz (the default speed).   Power draw at the wall is reported around 1435W.

Hashing speed as reported in the web UI varies from ~ 310-340Mh/s.  All the dies appear to be operating.  I haven't had it hashing long enough for the pool to give an accurate performance report yet, but it is now showing 277Mh/s and rising.  I think it's including downtime in its calculation.

Edit: Pool reported hashrate has stabilized around 317Mh/s, with a 3.2% stale share rate.  That's a somewhat higher stale rate than my gridseeds, which measure 0.12% stale on the same pool.
Lowering the difficulty settings at the pool may help the stale share rates but many pool difficulty levels are dynamically set ...  I'm sure the pool operators don't mind setting the bar a bit high for the hogs to slurp up all the shares... No offense to any Titan owner, just an observation. But seriously, I'd see if you can lower the diff a tad on the default difficulty settings at the pool for Titans because higher difficulty blocks take longer to solve, and it's easy to go one multiple too far, which would indeed cause an increase in stale shares... it's easy to overlook when the hardware's question-ability is distracting you from the big picture...  Stale shares are reported when it has literally taken too long for a result, and not attributed to the functionality of the miner in this case because we know its hashing quite fast. Another pool, with lower default settings for scrypt asics may be the key.  Did you try Ghash?    Good Luck

My Titans should be arriving any day now.

What type of PSU is best to use with these? From what I've read it seems like people that are actually hashing at 300 mh/s are seeing 1200-1250 watts at the wall.

I use Corsair AX860 with 2 cubes and AX1200 with 3.

But I don't clock the cubes at 300 or 325mhz to prevent burning cables/connectors.

I was thinking about running 2 Corsair CX750's per cube so I could run at 300 or more. Will that be okay you think?

Don't worry folks (you too Searing),KnC ain't going to just fuck their customers...they won't be happy till ALL $2 BILLION worth of BTC belongs to them & them alone!!!  Angry

If no one can stop them from taking over a VERY large portion of the network via mining...then Bitcoin itself is in jeopardy,IMHO  Roll Eyes



egdar = searing ??
Ridiculous and irrelevant, KnC is the topic.
No need to distract from the core topic or incite sympathizer of edgar/searing against each other to take over.

[snip]

For the bigger picture and widespread long term adoption I think 1) is the better way, for your personal wealth and profit 2) it is.


Shouldn't this be moved to the mining speculation category ?

I don't like how KnCancer has grown on the disadvantage of their customers  host cells, but actually I'm wondering what's the better scenario for BTC's mass adoption.
1) Huge mining farms like KnC dropping >90% of coins mined each day on the exchanges
2) Many small miners, hodling most of their mined coins

Scenario 1 drives the price down if there's not enough people buying coins (btc awareness / acceptance not increasing). In best case this results in a stable low (btc awareness / acceptance slowly increasing) and helps spreading the digital wealth.

Scenario 2 drives the price up if there's more asked than offered  (btc awareness / acceptance increasing), but at the same time would slow down mass adoption and concentrate wealth

For the bigger picture and widespread long term adoption I think 1) is the better way, for your personal wealth and profit 2) it is.

Next take a look at the "CEO": https://www.linkedin.com/pub/henrik-ask/37/9ab/b4b
