Another major feature I added in test build today:

Translation of the firmware webgui to 80+ different languages!

Little preview ---->

Latest update of my firmware currently still in development & testing:

Recently added new feature. Internet outage / no working pool handling.
When either of those situations is present the monitoring script will sleep on a 30 second timer rechecking every 30 seconds. This way the miner isnt issued constant hard / soft resets while the inet or pools are down.

Well technically all ASIC mining hardware has variable power draw(load) from their power source.
Whenever theres a new block, work restart, network connection issue, pool lag. Hell I wouldnt be surprised if it was even more sporadic then just those, IE: If the firmware that queues work up for the ASIC's is written horribly ... it will cause all sorts of non full queues (cores doing nothing at any given moment).

Its highly possible that the ASIC you mentioned above is just a horrible chip off the block and requires insane voltage to run stable.

Clarification update!!! PLEASE READ!!!!

I have NOT POSTED a new ebay ad yet. The one currently on ebay is not the official source of the firmware. Currently the only official source is my website: gentarkincustomtitan.pcriot.com or myself directly.
I will announce when & if this changes.
I will announce when & if I post a new ebay ad.

Until then, any purchase made from sources other than listed above will be NOT BE ELIGIBLE for free updates to the firmware!

Please dont link that ebay ad. Thats vegasguy's ad and any buyers of that firmware will not be available for free future updates of the firmware from the legitimate firmwae source(myself).
If you are really interested in such firmware and wish to have free updates & fixes in the future then it can be bought directly from my website - http://gentarkincustomtitan.pcriot.com

Why not someone just email knc ... I emailed knc questions bout their firmware and they got back to me in a couple days.

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!

Update:

Going forward, all sales will be handled exclusively through my website: http://gentarkincustomtitan.pcriot.com

I will eventually create a new ebay ad as well, which will link to my site for clarity and customers of sales made on ebay will use my site as a portal for receiving my firmware & future updates.

All proceeds from sales on my site will go to the the developer of the project(myself).

I do not have access to the customer list that vegasguy maintained so  ... I will have to try and figure out my customer base from scratch. Anyone on here this forum that has purchased firmware using vegasguy's site can send me a pm w/ ur email and subsequently create an account using the same email address on the new site.  I will also need to see a copy of the confirmation email received when ordering from either vegasguy's site or a paypal receipt from ebay showing that the firmware was purchased from either source.
**NOTE** For the above ... customer verification only needs to happen when I release a new version of the firmware. So, there is no rush on this.

   vegasguy has closed the portion of his site for my firmware permanently, has also removed the ebay ad.   ... or so he says and has done, but may eventually try creating new sites .. etc..


Sorry for the inconvenience, I ask the community for patience as I sort this all out. I do plan on releasing the "energy saver" edition after this gets settled.


MAJOR RELEASE 3.3.16 - v1.0.0

wait for it.....    Wait for It............  WAIT FOR IT......................

RELEASE of GenTarkin's Mod ~ Custom KNC Titan Firmware v1.0.0 IS FINALLY HERE!!!!!!!!!!!!

Previous customers: head to http://gentarkincustomtitan.pcriot.com/custom-knc-titan-firmware-myaccount/ to obtain your FREE UPGRADE and license key(s)!!

New / Unverified previous customers: head to http://gentarkincustomtitan.pcriot.com/custom-knc-titan-firmware-shop/ to purchase!!

RELEASE NOTES:

Major Features, Additions, Fixes & Changes:
Added the long awaited “Energy Saver” feature – automatically tunes die voltages for highest effeciency while keeping the die stable as possible & hw% low. ~~MORE INFO HERE!!! ~~
DCDC Over-Current protection – any DCDC’s detected above 46A will be issued a die reset, if that fails then die speed is clocked down significantly to prevent DCDC failure.
Long Term Stability checking for all dies – bumps voltage up on a die if it becomes unstable more than 2x in a period of 2 days.
Per RPI Cube Tracking – if cubes are added, removed or moved around their last known clocks and volts on a given pi will be restored.
Internet outtage / dead pool detection to prevent miner from constantly resetting itself.
Slight webgui redesign.
Product license activation.
Full Copyright & end user license information.
Much smaller installation file.


Additional Features, Additions, Fixes & Changes:
Full translation of webgui pages to 80+ different languages.
Logging file output format refined and also includes more timestamps now.
Optimized timing of die / cube soft and hard resets.
Fixed format of advanced.conf file not being updated properly when user changes/removes/adds cubes or manually sets dies OFF.
ADVANCED page now shows which dies(if any) are being throttled because of DCDC over temp threshold.
ADVANCED page now auto refreshes every 5 minutes.
Noticed in rare cases dies are configured with positive voltage – wrote correction code for this.
For “Energy Saver” implemented cross reboots internal data array tracking capability.
Ability for user to save Log Files to a file to be posted or emailed for diagnostic purposes. (This is part of the Energy Saver options).
Added BALANCE strategy to MINER page – this may work better than LOAD-BALANCE for some users.
Removal of BFGminer version option – in testing 5.1.0 works best with Titans – can re-add later on as an optional installation file if demand is high enough.
More fixes to KNC’s shoddy code.
And many more small fixes / improvements too numerous to list.

All the previous firmware features and improvements are included!

Now … you’re probably asking yourself “yeah yeah, but how much do all these wonderful new features cost?” Simple: $75 first full copy, $35 for additional licenses.

Verified Previous Customers: The upgrade to this firmware is completely FREE for the number of Titans the previous version was purchased. Additional Titans require additional license purchase. If you created an account here previously then you will find license keys issued to your account. **NOTE** If you have not created an account on this site and verified your previous purchases, please contact me - http://gentarkincustomtitan.pcriot.com/custom-knc-titan-firmware-contact/

New Customers: Prices as detailed above.

***IMPORTANT INSTALLATION NOTICE*** – Upon upgrading to and activation of this firmware, its EXTREMELY IMPORTANT to keep track of which license was used on your KNC Titan(s). An easy way to do this is create backups of your Titan(s) after activating, then keep record of which backup went to which Titan.

***PRODUCT NOTICE*** – upon purchasing / obtaining this software, the end user agrees to the license terms set forth here(this file is also contained in my firmware): gentarkincustomtitan.pcriot.com/gentarkin_mod/LICENSE

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).

Going forward, all sales will be handled exclusively through my website: http://gentarkincustomtitan.pcriot.com

I will eventually create a new ebay ad as well, which will link to my site for clarity and customers of sales made on ebay will use my site as a portal for receiving my firmware & future updates.

Sorry for the inconvenience, I ask the community for patience as I sort this all out. I do plan on releasing the "energy saver" edition after this gets settled.

a, The DCDC's are programmable, so powering down the die is accomplished by issuing the DCDC's power off and on.
b, Yeah, there are versions of Titan which refuse to work w/ anything higher than like v1.03 firmware. Im not sure exactly what the difference is. I have yet to been able to remote into one of them(if anyone would let me) to see if I can figure out why the i2c bus refuses to work on these titans w/ anything higher than v1.03 =/

I just got back from vacation everyone. "Energy Saver" coding & testing will continue soon I hope.
Also, I will clear up confusion about the gentarkincustomtitan.pcriot.com website soon.

The intial and primary goal of my firmware since its inception and to this day has been to bring "sleeping, dropped or w/e u wanna call them" dies back to a hashing state. In order to do this my firmware issues cube power up / downs to bring back the affected die(s). In order to carry out a full power cycle on a cube bfgminer has to be stopped prior to the power up / down then started again after the power cycling.

As to why the pi may be rebooting on your. The pi reboots whenever it detects communication via the i2c bus to the controller board stops working(most likely due to the controller board locking up). Rebooting the pi instructs the controller board to power cycle & reflash the binary code to the FPGA which reinitializes the FPGA on controller board.

The controller board hanging like this, Ive witnessed over time are completely random. It can happen more often when voltages & clocks are being changed. (in some cases it will happen much more often during tuning of dies when my "energy saver" edition gets released)

Its most likely caused by shitty code running on the FPGA, which unfortunately is completely closed source.

Yeah, pretty much only first gen ASIC's were the real crypto makers in this game. Everything since then has been a race to make back ROI over a year w/ barely any profit beyond that, and by that time upgrades needed to happen to stay in that race. So, its constantly a cycle of not making much at all LOL! ...

Ah, now makes complete sense ... being that you showed me what an erroneous output from that command, on a bad board, looks like =)

Well, Im confused ... all that command states is the board powered up fine. LOL! So Im still not sure how that indicates failure.

What does that say about failure?

Yeah, its loaded into the RAM on the controller board and executed. Thats why it has to be loaded up each power up.

Yes the FPGA code is different for titans vs the SHA knc products for the controller board.

Well, due to complications and my desire to get "energy saver" done and released asap... the cube historic settings tracking feature may be postponed till a future release after "energy saver" =/
