1 week now and knc does not sent me repair Titan cube back?
?.?
yeah let us know the turn around on that
I've heard from some on here 2 weeks to 2 months
be interesting to know ......
Disregard below:
IF .... your are an "OLD HAND" at Titan tweaks fixes etc you can disregard reading below ...a pretty straightforward fix... ....this is for the 3rd batch guys
or the 'blessed' who have never had a Titan issue..as an aside best to keep this in mind and also make some microSD's as backup should such occur on your
units...no KNC forums etc anymore so....will post it here ..as some hopefully useful advice for folk not as far in the weeds as some of us with Titan drama
Anyway ... after a storm and a power up and down of the Titan(s) it its nice auto start mode .... I had my 2nd titan (2 cubes to a controller ..there are 6 on my other controller)
just up and die....with the NO CONNECTION on the LCD display..which was new to me...
all was well on all else ...so did a hard power off reboot and the miner would go up to like 9mh then drop to 6mh 4mh 1mh etc
did this a couple times and said ...damn I hope this is the SD card or she finally went to the promised land of 'doorstop mode'
again the other Titan was fine so I knew it was (hopefully not) any other issues on connection..
so I did my usual "panic process' (tm) ..much waving of hands ...jumping up and down....old hand Titan owners know this song and dance routine......
I have 2 set aside microSD cards with the current firmware 2.00 on them for just such emergencies...so I can just pop them in for such hopefully 'quick fixes' set aside in their little box.
I powered the unit down and popped the old micro SD and put in new micro SD setup ahead of time with v2.00 firmware etc..again power unit off and make sure you check for static elec issues before touching the board to do so ...ie see if you get a spark off your finger on a discharge on the metal titan cube as a guick check .the unit is powered off and wait about 60 sec after power off...do the static check above and swap out SD and pop the backup in..again ideally pre-made for speed with firmware 2.00 on it already....
..so did so ..ran my backup....tweaked the usual pool settings made sure all were OK and did a restart as directed after backup process file run...again this was as backup asked
restart not a power down yet
er .came up with a 3rd new bad die.....the Titan was messing with my mind on reboot ...got 3 bad dies vs in 2 cube setup vs the usual 2 dead dies with them set to off
ack! much jumping about and cursing ack! Did again the (above) Titan dance to the ASIC gods of despair
Again familiar dance to all the old Titan/Neptune owners on this thread
then did the usual FULL POWER OFF reboot rather then the restart (yeah I know duh!) which SHOULD clear such up.....and so far always has such issues on more dead dies.
and she came back up all was well ...and fine the last week etc...ALL IS WELL...It was a CORRUPTED SD card from the power outage an reboot from the storm.
I have surge protectors the good ones triplite euro 220 version 1 on each of 3 psu supplies...this is the 3rd time they have probably saved my equipment (from 2013)
....I'd recommend them
I did a bit of over kill I have ONE 220 Electrical 20amp line to its own 220v circuit breaker also ... its only line nothing else on the circuit for EACH of my PSU's with one of these on each line also.....(not an issue in the basement to set it up this way)......but kinda liking the overkill on this with the surge protectors...from the past issues of large storms ..don't ya know
here is the link ...again I run 1 on each PSU with each PSU having its own 220v line to the box these are 220v euro versions they come with a cord from the unit
to the triplite odd euro plug to the tripplite unit and regular plug on the end to the PSU's on the other end ...but you have to figure out what kind of 220v plug end you wish to use on your line from your electrical box (also on amazon) from the tripp llite euro 220v unit itself to the plug in on your house/wall etc..that is NOT included in the package.

yeah a bit spendy...but they have a pretty good warranty on failure if they fail and your equipment gets fried etc...and again has saved my ass at least 3x from what I can tell
since 2013.....so just saying...I assume it was a power out hic up also that messed up the microSD in that this whole process worked....a sign of the ASIC gods that the surge
protectors came thru yet again
so shudder to think what kinda mess it may have made without the surge protectors.......the micro SD's I use are Sandisk 8gb Class 10's and they are only used 1x new on the Titans
if I have issues they are 'retired' as a catastrophic backup etc at like 12 bucks with shipping for such on Ebay not an issue (the link i use below is legit on such)....a small price
to pay for redundant micro SD's retired in a box from firmware version 1.15..but still at 12 bucks not that hard to justify

dumps and reboots... but for the 3rd batch new guys of folks that have had few issues ..my setup/experiences/paranoid setup ..keep me sane and Titan(s) up
methodology
I'd not auto update your WORKING SD assuming such...make some backup micro SD's and always just splurge the 12 bucks and swap them out
if issues you can always swap back on a reboot (say you forgot a config setting or something that worked previous) you have a re-do rather then
hope the auto update feature works on your 'suspect' maybe microSD currently in the Titan
IT IS A LOT LESS STRESS to just do the above with a quick switch from your pre-made v2.00 firmware SD backups and
and also backup once in awhile using the KNC backup feature etc also a good plan
last point KNC techs at one time (hopefully they know wtf they are talking about) said the raspberry pi B+ 512mb can be used as a direct
replacement on the board...if the raspberry pi itself is toast (some folk had pi's arrive damaged with their titans) so for 42 bucks including shipping
having one of these (make sure the pic of what you get matches what you have on the titan also to be sure) anyway having one of these
also helps the peace of mind
you can only prepare for what you can good luck if nothing else make a couple microSD cards with the v2.00 firmware for such issues
as I have had above
