Interesting. Did you power down the die by dropping the DC-DC's to zero, or did you use a command in the KNC chipset? I don't see anything big enough on the board to be a 12 volt interrupt.

Interesting. That explains why when I fired up a 2.00 code set on my Gen 1 Rpi it kept rebooting. It's something inetc/init.d, I stopped it by moving all the files in there into a "fubar" subdirectory. Whatever works.

Now working on compiling the code to run on a straight beaglebone+neptune. Should work....

hi,

i am very intereseted by your custom firmware, but i one of my won't start, itried with differend cable and power supply but it won't start.


Do you know where is the problem ?

Do you think your Firmware is able to awake this cube ?


thank you in advance

the power supply shut down when i tunr it on.

Do you think i can fix the problem ?

if it is a Fet i will difficult to find and change.

problem is i live in France and just for info what is the price to fix this cube

supposedly....thou there is a difference between the Oct 2013 and before Jupiter/Saturn/Mercury controllers and the Nov 2nd (last) batch of Jupiter's only

so you should probably try this with a Nov Jupiter board...what I was told on knc forums by knc techs (for what it is worth forums are down...damn I wish

someone had archived it...I go to way back machine and only get back to the titles of each msg lol )

anyway I heard they work ....and probably even with the controllers before the Nov units

should be others on here that have done such I'd think

the question on here that I'm chasing is with a 'cloned' titan bridge/daughter card (needed) from the PI B+ 512mb and the say Nov Neptune 6 port card

can you get THAT to run a Titan......have the cloned bridge coming..have the proper pi B+ 512mb (supposedly as told to me back in the day by knc staff...still iffy
clowns) soooooooo..


anyone want to send me a Neptune card to try (I'll send it back) a guy SHOULD be able to tell if this works with the LCD and the GUI coming up even with NO
cubes..if that happened I'd prob take a chance and try a cube..but have NO neppie controller

anyway other thing that is being kicked around

France is not too far away from the US, I can PM you a price but posting pictures is the best way to start.

Alright, I've sold most of the KnC Titan Bridges. I've got 2-3 left. If anyone wants more than that please pm me about it so I can see if it's feasible to get more made.

If you have PSU's randomly disappearing from your Titan then you have some burglary you should check into =P

On a more serious note, are you referring to dies which eventually stop hashing and a power cycle is needed to bring them back?
If so, then yes, that was the first thing I addressed when I bought my Titan, just to see if I could issue power cycling of the dies as needed, automatically.

That was one of the reasons I started writing the firmware mod, once I found out this was possible a whole galaxy of cool ideas were born and thats what my firmware is today =)

So, my firmware will power cycle the DCDC's of a cube when a die on that cube is detected as being "sleeping, dropped off, stopped hashing ... whatever you wanna call it" ... so far, taking into account peoples success w/ my firmware. Id say about 99% of the time my firmware brings those dies back hashing =) .. it works flawlessly 100% of the time on my titan.

If theres a true hardware problem w/ ur titan tho then of course my firmware cant do much bout that =P

Check out all the features of my firmware here: http://gentarkincustomtitan.pcriot.com

I just read my site and seems I didnt have that clearly stated in my list of features of firmware. I stated it in paragraphs above it but I can see how that can easily be overlooked. So, I just tweaked the list and wording a bit =)


Oh wait wait, I just reread what u asked. Are you talking about one of the DCDC's disapearing for a respective die but the die continues to hash?
If so, to answer that, my firmware on its current release does not address that problem. Its rare and I didnt catch it for a long time.
Sometimes when it does that it will drive the single remaining DCDC as hard as it can and pulls near 50-60A through the poor thing =( ... eventually the DCDC will simply just shut itself down because these DCDC's do have overcurrent protection & overheat protectio(both extreme cases) built in. If the DCDC doesnt entirely shut itself down it will go into a current limiting mode where it will give the ASIC all the power it can but in a very spurty manner, so the ASIC can hash at roughly just over half the speed(half the output from the ASIC will be HW errors) while the DCDC can remain powered on.

The next release my firmware will catch that condition and it will power cycle the affected ASIC and bring both DCDC's back online(given that one of the DCDC's arent permanently damaged).

well I'm not gonna slam you for helping me...but has anyone tried this with an OCT jupiter/saturn/mercury ..they do not work with a NOV Jupiter cubes etc (mix/match)

that is my question as well...I have an OCT Jupiter Board...but to be safe ..someone should at least TRY this first with an LCD and the GUI with NO cubes and see
on ideally 1st a Neptune board in question..then next likely is the NOV jupiter board (last run) then perhaps my OCT Jupiter or others like saturn/mercury boards?

if it kinda works before tossing a Titan cube to sacrifice to the ASIC gods .....with this OCT Jupiter board

I agree it SHOULD work....at least as a test with the LCD and the GUI with no cubes to start...but again ideal would be with a neptune controller 1st imho

THAT is the main issue...i have a clone bridge coming..got it as a spare (miners are 14.5 months old orig titan warranty was 90 days sooooooo seemed prudent
with 2 titans and the 'possiblity' that is the missing piece to the controller problem ..a complete clone hardware work about

supposedly have the proper pi (nov 2014) as a spare also ...according to knc tech staff at that time (assuming they know zip) raspberry pi B+ 512mb model


just trying to help ....don't like the way i say or do such ...big whoop....at least I'm trying to ask some questions on this (ie will clone bridge work on neptune 6 port board?)

anyway thanks for the confirmation ..I will take it as help from you....no issues...BUT some confirmation of HAS SOMEONE ACTUALLY DONE THIS YET would be nice

If so I will gladly try to be the crazy 2nd guy to do so...even on my Oct Jupiter board....(the bridge clone is in the mail)

anyway thanks for the input ..if you have further info as to who has done this already shoot it out here as well for all of us....

Yeah, I just checked hashrate. I think its just variance, theres been a bunch of spikes up this high within the past few months but overall diff has very slowly risen. So ... theres not too much going on in ASIC world of scrypt. That is unless this hashrate keeps up then we are all in trouble LOL!

At least LTC's diff isnt rising like BTC's diff ... yikes!
