lightfoot,

What did I mess up the RPi or the controller, please see the picture below? Only 1 LED is on instead of three and red LED on the RPi is off. Screen lights up but without any text or bright light at start up. I was using 2 PSUs but 1 to power both controllers, probably turned on one before the other or something to create a short. I can access the web GUI, but it won't show any cubes or hash.

Which leaves me three dead Titan boards to fix. These are really odd: The main symptom is that the boards have 0 ohm shorts on pins 4 and 6 of the 10 pin ribbon cable. This forces down the FPGA and crashes the whole stack. The user said there was some sort of power surge that took three of them out but I don't see how: The FPGA is isolated from 12v power by the TPS chip (blown) and the signal voltages on those lines are small. The miners likewise don't put out that much current there, and so far I have not been able to fuzz out where those lines go.

Hm.

That Titan is now stable as a rock. I set the frequencies to 300mhz all the way around and no more problems. Once again I think KNC has some sweet spots with the chips, use too low a frequency for the voltage or a significantly different frequency from the other dies and it resets the power supplies.

Titan 1 is hashing at a full speed of 80mh. Titan 2 (the filth one) is hashing on two cores at 40mh, waiting for the two new power supplies to come in. Once those are here I will secure them to the board and go from there.

First two repaired controller boards are on the way out as well. Getting there....

My titan has recently started doing the same eg...



This cube goes after a few hours, asic 3 follows suit not long after, and a couple of the others go after that.

Restarting or changing voltages/speeds does nothing, but if you power off and then back on it works as normal for a while

Sadly I'm not near my server room so rebooting is not something I can do very often, so I am also curious if gentarkins firmware can solve this, he used to have a test version, don't mind paying $50 if I know it will work but here in the UK the titan is nearing the end of it's profitability anyway.
Sweet. Apparently there is a soft reset (my guess is "soft reset all power supplies explicitly using waas or direct SPI pokes) followed by 8 power ups. That will do it.

And Tarkin knows about this and is writing the solution into the next gen of his code. So this can be solved by software which is a lot better than sending it to me to swap power supplies.

Noted, moving on. The right way to turn off a Titan remotely of course is to just remotely turn off and on a small relay connected to the power supply enable line (the one we always jumper). But software is simpler.

Hm. Well, this is interesting.

So I fixed Titan #1 here and brought it online for testing. All 8 power supplies come up, all cores, hashied at 60mh with temps on the chip in the low 30's, power supplied averaging around 50c. Left it alone last night, checked in this morning.

Hash speed in the 40's. But under advanced tab I see that one of the power supplies is just *missing*. And the other had a current of zero, rhat's odd.... So I tried changing the voltage, applied changes, and quickly noticed that power supply 0 (the partner to the now missing supply 1) was trying to put out 50a to meet the chip need. Turned that to OFF *fast*, then turned it to a low 50mhz. Which it will supply:

....

Right back to normal.

This is an odd thing, and if it's something that happens to others I wonder if it is the source of the "bad die" issue. Is this what Tarkin's software fixes?

What concerns me on the side is that I was able to try and get that one remaining power supply to supply all the hashing power, that would blow up a supply quickly.

Thoughts? If this is known and Tarkin fixes it for $50 by turning off then on the errant supply pair then this is not an issue I will fiddle with.  (Running Titan 2.0 software on this particular system, no special hacks)

Yep, there are "islands of stability" in Neptunes. Strange, but something to note. Maybe the slower clock speed interferes with the power draw of the chip, causing the power supplies to restart. Hm. Tried running the junker at 100mhz all chips and the power supplies are at .8 volts, but all currents match and it's hashing at a very cool 100gh.

Anyway, I'm a bit curious as to why Titans are still such a good deal. With one running at 60mh @200 watts one should make 1.15ltc a day or 4 bucks a day. Difficulty doesn't seem to be doing squat in the LTC world. Power usage of 200w is 4.8kw a day or 50 cents of power at .10c/kw.

So each unit makes a profit of $3.50 a day. Hundred a month profit, 1.2k in a year per cube if not much changes in the ltc world.

That's interesting. Somewhere in there is a math error or something, because price always seems to match power required to hash the coin.....

Oh well. Other things to do in the next day or two, will pick this back up mid-week.

Well the Titans difficulty wise should have been 'toast' around May/June 2015 if new equip could have come out in march as stated...

firms such as alpha tech/flower tech/volcano miner etc....all around 500mh etc..the price of ltc dumped to what 1.40 usd or some such thus NO one made any

thus Titans ARE still the top scrypt miner out there ...is not scrypt data halls that I'm aware (sfards?) so there you be

an A2 Terminator uses the same watts for 110mh as a Titan 350mh uses fo same ....

anyway how i got my good deal on a titan march 1st 2015 panic on the new equip and knc (we thought) big dump on 2nd titan run perhaps a knc data hall for
titans etc....I got my Titan 2nd one (all good dies) for 569 usd and incl shipping from Australia! The guy got a neptune for like 11 btc when btc was 1000 or so
upgraded/ithat neppie order (same price) to a titan and just wanted to get his original btc back ..thus the 2.69 btc I got it expecting to mine maybe till June/July at worst

so no new equip ..difficulty went up for LTC some but not a big deal for titans but for say a 50mh 1200watt gaw miner shut down as such ...elec too high

thus  old equip falls off the bottom end of scrypt miners as they go to doorstop status due to diff rise and high elec use per mh...and no top end stuff to push the
titans down.....viola

add the price of LTC now at 3.50 or so and well if 650 usd btc comes to pass at the current 0.008 ltc to btc ratio .which is low imho) that is 5.20 usd LTC

at that price I can run this beast with my lower elec costs thru NEXT winter

now if LTC pops today to 5.40 usd ..you'd see scrypt asics hit quick ..maybe i'd only miner till nov.....but w/o new equip or even equip that comes out in my mh range
500mh at 1150 w folk say ....my titan is 350mh 1250 w ..i can run with that pack for a bit

so anyway...titans shoulda been toast in june/july...now it looks like maybe I can run them thru next winter (heat benefit and elec costs less probably)

sometimes dumb and lucky is the best plan Smiley

That's a bit odd. I tuned down one of the test Neptunes here (the water block equipped junker) to a clock speed of 300mhz and this morning noticed it was hashing slower. Power supplies 0,1 were .8 volts, no current. (note: They should be .78v). Reboots did not change anything.

Put the clock speed on that engine back to 350mhz and the power supplies came right back. Tried a similar thing on the other Neptune (600gh, 350/450/450/450 solid as a rock) and sure enough the supplies I moved to 300 shut down. Did through a reboot. Reset, no problem.

Weird. I am running 1.02 of the firmware for testing (was the first I got, consistency is key) but weird.

yeah info on 'dead die' issues.....is re-paste a good bet on such? That I can do myself (maybe)
No, and since I am just starting on the dead die thing I am wondering if the dc-dc power supplies are what is causing dead die (not the same as board shorts out whole Titan thing). So don't replace everything yet :-)

really really want someone to donate a bridge/neptune board and pi and just see if such would at least come up with the GUI and LCD as working even w/o cubes

I can ask the guy that sent me this Rpi but when I am fixing controller boards (Titan or Neptune) I always use a BeagleBone with Neptune code as the test CPU and there is no problem testing/running them. I would find it spectacularly odd that a Neppie board will not work with a Titan at this point.

But there are some oddball differences in the Titan. This power supply vanishing act is not like the Neptunes, and these boards that shut down a controller (and quite possibly would burn up the FPGA) are a different animal as well. I'll need to spend a week probing gently to see what these are doing.

yeah it is just damn hard to put a titan cube on one of these puppies w/o being sure..I did some quick figures...if as folk say BTC goes to 650 usd in 2016 and LTC still sits at its historically lousy 0.0008 ltc to btc...at 650 for btc that is 5.20 for LTC .....at double the difficulty for LTC I can run my Titans next winter at the reduced winter elec rate
and still get 400 usd a month ..sh*t these puppies MAY just run into next winter on mostly the electric rate savings from my local util for winter electric rates

now ...I'm not so sure we will see many 'home scrypt miners" or any data scrypt halls for that matter at 3.50 usd for LTC ...but if it was 5.20 LTC price that would change quick imho

anyway....thus the issue with the Titans ...it has been almost 15 months running for my units...they were initially expected to run probably 6 months max and orig warranty was only 90 days (they screwed up and left 1 year on the web pages) ....so.....you see my issue ...stuff will start falling off the wagon here I think...would be nice to know how to tweak these puppies on the hardware end as well as the firmware end like Glenn Tarken has done

just saying.....got to keep them going for 'space heater' savings into the winter of 2017..but by doing so....I don't really want to blow them up testing stuff unless damn sure of the outcome....just saying Smiley

anyway it is all gravy for Titans now...the puppies were only supposed to maybe last till may/june 2014 with all the big ass claims of big ass scrypt miners coming out...
remember alpha tech/flower tech/volcano and others?... all 500mh machines etc..but scrypt prices crashed and thus zip came out...sometimes just being damn lucky is your own reward Smiley

DC/DC   Voltage (V)   Current (A)   Power (W)   Temperature (°C)
0   0.7394   12.1562   8.988   44.100

(note I also cut the voltage back on core zero).

That's weird. So I went over, power cycled the cube and controller (need to put those on separate supplies) and:

DC/DC   Voltage (V)   Current (A)   Power (W)   Temperature (°C)
0   0.7397   5.8984   4.363   38.100

7   0.7960   32.8125   26.119   43.500

Back and purring. Bringing it to full speed gets me:

DC/DC   Voltage (V)   Current (A)   Power (W)   Temperature (°C)

Well with the power supply pulled it comes up. That's one Titan miner running. Got another Titan going here as well, testing it with a very low burn rate of 150mhz, stock voltage, purring at 42mh, 31c chip temp, 42c dc-dc temp. Will let it purr for awhile.

Looks like we can repair Titans!

yeah info on 'dead die' issues.....is re-paste a good bet on such? That I can do myself (maybe)

have had 2 dead dies since I got the orig unit...need a 'good' reason to muck with a cube working 3/4 (cowardice has worked for me well and holding LTC till move to BTC for the equiv of
since Titans 47 btc..we also serve who scream like a girl and run away from such 'operations' as you preform! ) Smiley

really really want someone to donate a bridge/neptune board and pi and just see if such would at least come up with the GUI and LCD as working even w/o cubes

then again the BBB project may eliminate that I guess


er crap

someone trusts me enough they could I suppose send me a Neptune 6 port  Board....i have a pi B+ 512mb and a bridge coming (figured like 100 bucks each for each titan it was a deal as
insurance my units have been mining 14.5 months now ..bit more was .5 btc .but hell I made that on sig campaign over past year so wth) Smiley

Note to self: Charge a fee to clean a filth-covered board. Yuck.


On the other hand the back of the board shows no heat damage, just destroyed power supplies. My guess is that the caps and fets were covered in filth and the usual happened....

Oh and the power Molex connector is on the way out. Need to replace that too.

On the other hand, first Titan in. Next batch coming. Busy weekend ahead.

i have a neptune cube that used to work and one day it just stopped , what happens is if u plug that one cube into a controller it freezes up the controller and none of the other 4 cubes work.
with that one cube unplugged the neptune works just fine. any chance u think that cube may be fixable?

So anyone have a trashed Jupiter board you could send ...to test this theory?)

Yep, works. There is no physical difference between a T and N controller baseboard. In fact I'm working to get a Beaglebone to run the 2.00 Titan code. It's a little different but not much and they included all sorts of nice source code....

damn ...I SOOOO drank the KNC kool-aid back in the day....they were a 'reputable' company in 2013 ..its like watching a NUN turn into a PORN star ...all very fascinating to watch like an ASIC Swedish Soap Opera....but damn sad on reflection Sad
I see that Antminers and now exploding in flames too. Though that's probably because people are running 8,000 watt power supplies into them. When there is a capacitor short those don't just go pfft and trip the power supply, they explode the capacitor and the manufacturer can't do a whole lot about that... (the technical term is AIR or Amp Interrupt Rating. It's why you can't plug a 15 amp appliance into a 20 amp outlet....)



yeah they have a group order as an example on the Avalon 6 for $1100 w/o shipping now...I do the figures on the www.tradeblock.com calculator and it just don't fly at my regular rate of 13.7c kwh..my winter rate is 9.27c kwh so maybe some used equip next winter I may be able to mine yet

but with difficulty increase with all the big btc data farms etc coming out ..just can't see getting an avalon or Antminer at this point in time

anyway ..if I had a NOV Jupiter board I'd try this...but I have an 0CT Jupiter board and in that they don't work with the Nov stuff ...probably a no go Sad

If you ever get time ..I assume you read the post on using just wires etc to jump w/o the use of a bridge board on the titan at al

however I assume if your beagle bone project works ...this will be the work around ...ie slap a bbb into at least a Neptune Board and viola ....off to the races Smiley

Stupid KNC had any PR skills or gave a damn about image...they would at least at this point in time release the source code etc...but why 'brighten' an otherwise
'dark' hard earned reputation at this point in time?

anyway like the thread ...keep up the good work Smiley

Status: Had two more Neptune/Titan boards come in, both were solid dead. One is back up and running with the TPS power chip replaced, the second one still does not come up and it looks like the FPGA is shorted. Contacted user to see if they want me to replace the FPGA chip (costs .15btc by itself), will see.

It's looking to be about 50/50 in terms of replacing the power chip vs. the FPGA to fix these Titan/Neptune controller boards.

Now I just need to wait for the postal service to deliver more packages. Then we can start on reflows/rebuilds of the power supplies (bit more fun)



So NOW that you have compared the boards...Titan and Neptune are they REALLY the same boards? Would like to clarify that and off hand I'm curious on HOW they
compare to a NOV 2013 Jupiter board (the oct and before jupiter/saturn/mercury boards are NOT compatible with Nov cubes/controllers)

So I'm going with the fact that perhaps THEY (NOV Jupiter boards also) ...were the same and the start of the SAME boards for Nov Jupiter/Neptune/Titan string of
6 port controller boards from then on?

So anyone have a trashed Jupiter board you could send ...to test this theory?)

(or have I missed the memo and it is as I think it is above ...and I'm the last to get the memo?)

by the by see my setup below....I had TWO old dresser's with heavy glass tops...put my miner setup on such for fire protection (yep they was catching on fire the 1st month folk said w/o the 2 prong to 1 progng psu adapters) ...and the wood top work bench....I also figured would be very 'cool' on the glass top....so kinda reading the above pleased with self
I did that last summer..have not looked but suspect NO browning as a result of such actions

The fact that the DC-DC converters are showing voltage means they are probably working. If they were shorted you would see 0 volts on that die. My guess is nothing is pulling power from those particular ones, that's why they are cold.

Ergo, chip problem. You can try a low frequency on those dies, see if they respond to that.

I tried the lowest voltage and the lowest frequency and they are still dead. Been like this ever since I got the unit. Figured it might of been an easy fix.

I got 2 dies like this from day one .....nov 2014 1st batch units are notorious for having at least 1 dead die...but it was usually 2 dies 1 dead and 1 slow it seemed back
when folk were yelling and burning torches on knc forums to no avail

but yeah me too 2 dead dies orig unit

got a badly abused used titan in march when we all thought all them new bigger scrypt miners were coming out (volcano/alpha/flower/etc) so figured at the time
my units might last till may and paid appropriately ...not sure if ebay search goes back that far but the problems with firmware and other issues they were being dumped

my 'regret' is I could have gotten a titan cube like may 2015 or something for 500 usd buy it now...passed i mean LTC was 1.30 or so.....duh....my hope is the same NOW
with the price....of LTC say as an example.....if price would pop.....we would be golden

anyway the 2nd used unit I got in March was run in hot outback of Australia no a/c (or hell it could not keep up) in an apt.and had blown thru 2 or 3 psu's due to heat
the paint on the cube ...looks like the hood of an Arizona car parked in the sun for 8 years..sheesh (very retro looking thou I must say..you can see the paint speckles on
the top from the heat..I kid you not)

that titan unit complete still runs 350mh full out balls to the wall....my orig 'babied' titan unit...has the orig 2 dead dies and 2 dies on a cube 1 set to 250 the other to 225

so go figure it is all about the dies...the 1st run titans had lots of bad dies....it is the luck of the draw imho some got Titans back then with 1/2 the die dead Smiley

got the re-paste i got with fan and heat sinks (Swedish guy mod video on this thread)  stuff I could try ..but I've lost 5mh since these Nov 2014 units were gotten .....both of them nov units 2014..that is what now 14 months on the orig miner..yesterday Smiley

So am not gonna sweat it and burn a cube (yet) There will come a time when I will probably have to do the re-paste and mods etc..but only losing 5mh from 650mh to 645mh it is
JUST NOT worth mucking with them yet (knock wood)

anyway again imho the reason KNC overclocked these beasts 2x (orig 250mh machine..then 300mh firmware when late by months...then bad dies changed firmware to make them use the 325 setting to 350mh units...so they could get out of masseve RMA issues....and of course 2 prog to 1 plug adapters so they STOPPED catching on fire Smiley ).....so again ...anything anyone can get over 300mh is a gift...so think long and hard on if you really want to muck with a cube that is working overclocked 3/4 of the dies.....you could kill the works (being a coward seems to work for me so far.....) Smiley

Anyway to me the risk/reward is just not worth it..then again I have 2 Titans and one was way way golden at 350mh so ......i have some slack for my ego on all this....
