Quick question...probably obvious and will work...but are Mercury/Saturn/Jupiter/Neptune Ribbon Cables ARE THE SAME and can be used to run Titan cubes?
again 99% sure...but hey...figured I'd better ask

No clue. However those solder balls around the bottom two dies are interesting. It's possible that one problem is an overheat which extrudes solder, either shorting the die's +.8v supply or (way worse) shorting the SPI communication bus (which is common to all 4 dies).
Hm.
Hm.
KNC SCAMMERS... DEAD?
Meantime I tore open a chip to see what's inside. Needed stupid amounts of heat.
Now to see what can dissolve that glue. Theoretically I could open a chip, desolder and pull the bad die, and get things working again....

Anyone having problem with the KNC Neptune Web interface?
I cant access the first site, and not the "advanced settings" either. The neptune does not work, but I can browse the other menues.
I am willing to pay for someone to help me with this one.

Ack! Mordor! LOOK OUT THE EYE! (shudder)
I would however go to the 'dark side' with KNC if they had a 'garage sale' of Titan crap ..for the cheap......( sorry kinda an asic titan slut yet)
Very old news
It's December and here's a video of your favourite bitcoin turkey - Scam Hole:
https://www.youtube.com/watch?v=RDnA6i6oEvA
Pretty boring overall. And must have been shot a while back as there is also a video featuring recently fired Nanok Bie.
When the interviewer asks at the start where Scam got his money for all the hardware, Scam avoids mentioning hestole got a free loan from customers without their permission.
Also Scam mentions how kfc are going to go back to consumer sales again in the future when the price of bitcoin rises sufficiently. I assume he hopes everyone will have forgotten about past exploiting and screwing over original customers. And current lawsuits.
What else? How kfc plan to get control 40% of bitcoin network. And early in the video Scam explains how to hijack the bitcoin network, so it's obviously something these kunts are thinking about.

Thats just like any current or potential cryptocurrency ASIC designer / manufacturer.
Everything mining related places their bets when prices start climbing ... till diff catches up. After diff catches up those designers / manufactures cash in on the stupidity of the remaining sheep miners.
Then once price falls, many ASIC companies fade to dust w/ legal battles, after theyve made their fortune ripping everyone off.
Its the nature of all cryptocurrency mining man.
Hence why GPU's were awesome. AMD didnt give a fuck about miners at all.

Let's hope justice in Sweden isn't as poor as we saw in Norway this past week
I admire the folk who put 1.5k down per Titan or Neptune to fight this case. (If they lose they may also have to pay as much as 3k each I heard for KNC's court/lawyer fees ..how it works in Sweden) anyway ...I had no balls to try this
(to those doing so I salute you!) Hope they win!But
this class action ONLY applies to the 50/100 (unsure number) who got into the class action paying the above...once this court case is settled no other class actions can be
taken it will be a done deal
so I hope the win...but win/lose/settlement ..it is not gonna effect any of us NOT in the lawsuit
MY own view is the class action will LOSE...hate to say it...but KNC's point of all us miners when we bought the equipment were automatically under Swedish Law considered
a business thus NOT able to be under EU consumer protection. So IMHO there is a reason Swedish Law has this loop hole to get out from under EU consumer protection rules.
ie business purposes you are not covered. SO I REALLY doubt that a Swedish Court will overturn such laws in that they seem to be in Sweden's interest to get around EU consumer protection and other rules.
Just saying why I did not pay any $$$ and jump in.
I gave the odds of this at 50/50 before BFL walked. Now I give the odds 80/20 for KNC. My view is KNC is gonna pay its law firm a LOT of $$$ not reimburse 100 folk say 10k each
with damages....the class action folk got 150k up front..but KNC would stand to lose at 10,131.80 each (my cost with shipping to usa) so say 10k each $1,000,000 dollars plus damages to get orig amount back vs teh class action folk again who got 150k up front win/lose or draw...
anyway we will see......but man it would so suck big time to dump 1.5k and be liable for knc's legal costs on a loss of say up to 3k and be in the same boat screwed on equipment
so I salute them......they got big brass ones!
oh and the 1.5k was PER UNIT up front no refund ....ouch

POLL:
Based off of ... I believe lightfoot's recommendation ...
For my next release, who would find a "cable / connector life saver" option valuable?
Basically it would be an algorithm to guestimate how much power is being drawn through each PSU cable assuming the Y connector & 2 PSU cables are present, per cube.
The algo would then take into account current draw per DCDC & overall watts & possibly even temps guestimated by the cube and then drop the clocks down until the power usage would be below 140-150w per cable coming off the cube.
This would of course make the Titan slower but far less risk of burning cables.
I really dont know how valuable such an option will ultimately be, because I know most miners just want to push these things as hard as they will go and when stuff does burn up, just replace and move on.
So, may be a lot of work for nothing really. But its an interesting idea =P

I have noticed that when multiple dies fail at the same time that this is a great signal that there is a power problem. I have alarms set when mh/s drops below a certain level I can manually monitor the advanced page. On the last alarm 2 dies failed at the same time, on the same cube and your firmware soft restarted them. A few hours later the whole cube failed because the psu shutdown so I checked the cube and discovered the fried pcie connector. And this PCIE was seriously burnt, there wasn't much left of it, the male/female were melted/fused together, I needed pliers to separate them. In this case restarting the dies earlier certainly didn't help.
So maybe some logic that when 2 or more dies fail at the same time just shut the whole cube down till it is cold started or rebooted. I don't know if or how often this would generate false alarms, but I've never noticed 2 dies failing at the same time except in this instance.
Unless that exact situation can be reproduced more than a few times .... it could have been just coincidence at this point =(
Even then, 2 dies could go down around the same time and there not be any power issue at all. Ive witnessed it several times on my Titan.
But, a definite pattern of many different miners would have to prove this is the case before coding this into the firmware.
It is possible to measure this. Usually we have an input of 12.0 V. If the connector starts to be fried the resistor of the connector is increasing. Thats why the connector is getting hot while a high current went trough. At the DCDC regulator the input voltage will get lower. When the voltage is lower, the dies are failing more often. The DCDC regulator provides the input voltage VIN as well. VIN is currently not used by the firmware. But it is already coded in libpmbus.c Have a look into function test_ericsson
pmbus_read_vin(i2c_bus, ERICSSON_I2C_WORKAROUND_DELAY_us); may be used in waas.c
I was bit surprised when after modyfing cubes per youtube video (anyone did put heatsink on all DC converters?) and applying new thermal paste I managed to get my problematic dies to work at full spead. I had 2 that would run at 125mhz max. now they running at full 300mhz (didnt tried more).
and was shocked how dried up thermal paste was on some cubes:/
btw anyone ever tried to put some water cooling?
Boy that's interesting! Nice job, what were the symptoms before re-pasting the dies?and was shocked how dried up thermal paste was on some cubes:/
btw anyone ever tried to put some water cooling?
I just took out about 50% of the hog on a board that was kind of shaped like a taco chip with all dies dead. After a reflow and gentle torquing of the board to remove the sag, I have two dies are running at full speed, and the other two put out a lot of noise and fail (so they have to be disabled). The source of the hog was probably having the heat sink screwed down way too tight (don't do this).
The remaining two do the "mumble" error when powered on, in BFGMiner you see tons of shares without requests coming in on all four dies, making the unit hash slowly. Still pulls full power on the dies, but garbage output. Turning off the dies makes the remaining two stable at 300mhz/40mh.
Edit: This is an example of the gibberish message:
[2016-03-14 21:33:38] KNC 1b[5:2:76]: Got nonce for unknown work in slot 5
As to water cooling I tried a Corsair H100 on a KNC Neptune. Worked great in terms of keeping the CPU cool, right up to when the unit leaked and vented the coolant with a foom. Oh well.
Yeah, I could never come to fully trust water cooling. Had some running great on 6 hashfast boards for as long as I was mining on them. But still... one small leak and its all fucking done.
Inside PC cases Im even more paranoid using water cooling ... I dont wanna destroy my computer ... lol!
Ive been using this computer for about 4 years now and I have never had a leak
good for you! =)
But for me, it all comes down to worse case.
CPU HSF - fan goes out, cpu throttles itself ... its obvious when cpu fan dies.
This largely applies to gpu HSF as well.
Watercooling - a leak happens ... stuff shorts and dies.
I prefer to minimize my risk.
