HOLY SHIT those 2 dies got way way way to fucking hot. Most likely fried the package substrate or something along those lines.
If its not working, that would be why.

I really wish KNC would have designed the dies with ondie thermistors. So we knew what the fuck the actual temps of the dies are...

Design of the cubes is terrible starting from screws holding everything.
I guess when I put it back thermal paste wasnt spread properly. dont have luck with titans and ebay. Cant wait for A4 miners

Yeah I have 1 cube with only 1 die that works coming (30 ltc). I got it to see if I could get that 'clone titan bridge' I got as a just in case (only 7 were available not sure
if any now) working as 'Frankenstein" titan board with the LCD from the 6 port I have laying about and the Jupiter 550gh oct 2013 4 port board...folk say it should work
Sometime the end of the week I'll try to get this to work. (or lond bang)
(must also dig out the 'Voodoo for Dummies' book and buy a 5 gallon pail of Chicken Entrails....knc devices require much work of the 'dark forces'

so we will see if it works with a 4 port Jupiter board and the proper pi and the firmware for a titan...if nothing else i may get BANG for my buck ....literally

The first step is get it all together and if the LCD comes up as Titan and the GUI comes up with Titan stuff but no cubes...(and no burning smell or smoke)
I guess then the 1 die cube will be ready for this unholy sacrifice.....

IF that works. I will next as a project delve into the 1 die only working titan cube.  (it has been mod'd already) I probably will re-paste it again and whatever other tweaks I may yet be able to do ..just to practice on something for the cubes that have 1 dead die or fading dies ......must have the proper 'subjects' for my experiments (bharahahahah cough) evil laugh sucks

anyway....we also with *no balls* may eventually creep up on these things and metaphorically 'wack them with a stick' to get them working..if not well
always the pleasure of blowing something up 'stylishly"

(man I need a life.....sheesh)

This is for Neptune users. (I don't have a Neptune). It is in German on Ebay and no idea how 'legit' it may or may not be.

But they are stating a 'firmware' upgrade for Neptunes. Just tripped over it thought It MAY (or may not) be of some note.

I've no idea. But I suppose Neptune folks can at least message the guy and see if it is 'maybe' legit or not?


for what it may or may not be worth below is the link. You will need google translate.

Hope it amounts to some use for you Neptune folk. Myself no clue only have Titans

Any pointers on repairing burnt power connectors on cubes ?

Here is the best, quickest, and easiest way to deal with a burnt connection in my opinion. It also allows about 3/16in additional contact between the power connector and the pins. Sorry its a bit of a hack. and you must absolutely be sure to put the connector on clip side up, ground wires up since the will not be a receiver connector on the board anymore.

The burnt connector will be brittle, and easy to break up with a pair of side cutters. Do it in small pieces until just the very bottom is left. Then pry up gently with a screwdriver to dislodge the 2 plastic retainers and it will slide right off. Then take a piece of 220 grit sand paper to clean up the pins. Clean everything up and carefully push the power connector on the bare pins while using a flashlight to make sure its on right. It will now go further on the pins making a better connection.  

Thanks! Very good hack indeed

So the class action against kfc failed??

strange because I got this from my lawyer "Finally, the date for the main hearing is set to 16, 17 and 18 (half day) Mars 2016."

Are you suing KnC as an individual or did you join a class action group?
Which lawyer are you dealing with if I may ask?

It'd be great if you can post an update after the hearing.

Yeah, of course the 12v aint going directly to the dies =P ... the DCDC's convert the 12v to .7v for the dies(chips as u call them).

I was thinking about this as a new Neptune repair came in. Same basic problem (shorts power supply everything looks ok) and it took me a few mins to figure out the problem:

Basically there *CAN BE* and sort of *IS* 12 volts to the die. The power supplies are switching supplies, which means they turn the high side FETs on for a short time, then the low side FETs on for a longer time to put a brief spike of 12v that is immediately brought back down to zero. The average is filtered through the choke (the big hot thing) to make a nice constant output voltage of .7 or whatever.

However those high side FETs switch a lot of current very quickly. If they overheat then they cur through and short. Now when a FET shorts the PN junction becomes a 0 ohm resistive path quickly. Which applies the full 12 volt rail to the chip die. Which either shorts the 12v supply or incinerates things quickly.

My guess is this is what happened to Wolverine's board. I can find these shorts and clear them, but the die is probably toast (like this Neptune, die is dead shorted). Wolverine if you would like I can take a look at the board and see if I can clear it. No guarantees, but I can probably get 50%-75% of the board working again which is still nice for a Titan.

cool. will send it to you. hopefully you can resurrect it

is $2800  - $300 a good buy for a titan that hashes at  340 mh/s ?

7-9 months  ROI , if you have free electricity.

Good news from Sweden! kfc have let go of 1/5 of their staff 
http://swedishstartupspace.com/2016/02/16/bitcoin-startup-knc-miner-downsizes-a-fifth-of-its-workforce/

Seems some chinese firm invested multi-millions in equipment and kfc are now very small time players.

So much for their dream to control 40% of the BTC network  

But it's not enough! I want this to be a reality asap


Your updates on the process of suing these crooks welcome here

Anybody on here have like 2 or more KNC Y adapters laying about they want to sell me. I ONLY want unused ones.

I discovered that my current ones (15 months) a couple had issues. No browning or anything, but the replacements I had that were unused

were quite a bit 'snugger' then the old ones I replaced. So anyway some kinda 'degradation'. So anyway I know a lof of folk got the longer

Y cables made direct to stack their cubes 3 high ...so if anyone has a new set of 4 as a result .let me know what you need for the price.

Again they have to be UNUSED for me to be interested. Perhaps I'm parinoid...but again we are dealing with 'evil' knc machines don't ya know.

thanks

what thermal paste for heatsink you guys recommend for titan?

If BFL got away with their whole bullshit and with a boss who was already convicted well I think that Markus and Sam will be just fine. Sadly!

perhaps it would be more fitting if they were human centipede-d into a circle so they might spend eternity swallowing nothing but each others' shit... perhaps

Since Im inching closer to release every day and hopefully its right around the corner. Figured I would post a preview picture of the ADVANCED page. Shows the updated "Energy Saver" options, also note the blue progress banner at the top ... this banner will be on every major webgui page while "Energy Saver" is in progress. That banner will turn green when tuning is complete and awaiting user input (Selecting to keep the tuned settings or revert to pretuned settings" ... once selected it will do what the user selects then "Energy Saver" will be turned off and user selection applied.
The HELP page which you can see linked there, will provided a form of Q&A for users regarding "Energy Saver" and how it works.

Went looking for the code today to see how you are satisfying GPL licensing requirements but don't see anything in the repo aside from a README, how are you making the source available these days?

Well, there is no GPL licensed code in my installation file, so I dont have to make the source available for my mod if I dont want to. All of the code in my installation file is licensed under MIT which is KNC's license of choosing for their overall project. Furthermore, my changes to KNC's original code is sublicensed under my own modified BSD license w/ nonfree restrictions.
Ive trimmed out all the files I dont use. The upgrade installation file shrank significantly from 20MB or so, down to 3.2MB.

+1 to that. Looks like their dream isn't working out.

[lightfoot]

And on a non-related note, I just figured out how to fix a Titan cube with 2 dead dies to hash at full speed.

It's Miller time!
