Okay, I'm posting this info NOT BECAUSE I NEED A FIX, but because I hope it will help GenTarkin with his software development…
I have an early Batch 1 Titan (Sept 2014). I have a total of five cubes, with a total of fifteen working cores among them. I keep the dead cores turned off. I keep the semi-dead cores turned off. The whole rig hashes at 280 - 300 Mhs. It needs to be hard-rebooted many times to run properly, and then it will only run for 6 - 12 hours without a reboot.
UNLESS...
The best firmware version for me is v1.15, not because it's good. Actually it sucks, but after a few reboots, the GUI crashes. It is completely unresponsive. When this happens, my rig will run at full speed (confirmed at litecoinpool.org) for weeks and weeks at a time. I think the longest it ever ran was 8 weeks without a reboot, but I can usually get a solid month out of it.
The point I'm trying to make is that my rig works perfectly WHEN THE SOFTWARE ISN'T WORKING.
My hope is that this information might help GenTarkin with his firmware development. I'd be happy to communicate about this privately.
I also plan on buying a copy of the new firmware to support his work.
Why not just try my firmware see if it works?..... can at least start out w/ the donation version =) which is on github, then if it works great for ur titan can buy it =) |

I tried that. The problem is I have the cap removed and I put copper heatsinks on the dies. The problem is the copper heatsinks is not enough to cool the dies so they overheat and shutdown before I can see the readings. With the cap on, its spreads the heat throughout the cap, and I cannot tell where is heat is coming from. Just hoping someone knew the locations of the die numbers.

Have you tried it at 50mhz low voltage? Not yet, dont know why I didnt try this. Will do today. I badly need to map these dies as I am working on a special fix. Vegas Better yet, I would try just turning ON one die at a time, 50mhz low voltage. That way the entire package temperature is lower too =) Traditionally, if ASICs are laid out anything like standard PCB components, wherever the little dot is, indicates "pin 1" or if there is no painted difference then its assumed to be to the left ... in this case the dot is on the upper left corner of the package according to your pictures. If its laid out logically like standard PCB stuff then that would indicate die 0, then again this is KNC we are talking about so... who fucking knows. |

BitFury's ASICs will work even better! http://www.coindesk.com/bitfury-completion-16nm-bitcoin-mining-asic/BitFury has announced it has completed the tape-out for its 16NM ASIC bitcoin mining chips, which were first revealed to be in production in February.
The chip will achieve energy efficiency of 0.06 joules per gigahash, compared to the 0.2 joules per gigahash of its 28nm predecessor. BitFury suggested the chip will deliver "four times the compute power" of its previous 28NM chip. I hopeeveryone realizes, soon as those 16nm chips come online at that power rating. If they just mine for themselves, they will singlehandly own the blockchain. Bitcoin will be effectively centralized therefore dead then. |

Guys I need your help. Ive looked everywhere for the correct location of the die numbers, and I just cant seem to find them. I need this information badly, as I want to test some new techniques for hardware die repair. If anyone has this information or can find it , I would appreciate it. If you know which die is which, Please use the pic below and edit it and post. Please dont guess. Thanks. Vegas  Couldnt u map it using the thermal laser probe? Install HSF, set one die to OFF, take temp readings on top of the base of the HSF, one corner should be cooler than the other 3.... |

MORE features/optimizations comin down the pipe:
So, just finished up some tweaks to hostname chars allowed & backup naming tuning. Basically KNC allowed characters that cause issues in the hostname, for example I tried ! as part of hostname and it caused webgui to go to a 500 internal server error ROFL!
So, now, hostnames are only allowed letters, numbers, spaces & - _ symbols.
Backup filename name strips out everything except letters & numbers.
Furthermore, submitting a blank name on system page now deletes the minername all together instead of saying "invalid name"
Also, Im adding a wall watts estimation to the advanced page.
Im wondering if anyone out there that has their titan hooked up to a killawatt if they could read me that measurement vs what the webgui shows for W.
That would be great!
This will help me w/ the estimation percentage I need to go with.
Also, if anyone knows, what the stock fan volts & amps are( that way I can put watts per fan into the equation) as well as I wonder how many watts the controllerboard itself uses. I estimate 20 maybe?
I know the pi uses very little.

At versions 1.02-1.04 I have cycling Cubes restarts it looks as temperature rises to critical and then restart. At higher I see no cubes. At MANUFACTURERs version 2.00 no cubes and [2015-09-01 16:51:31] I2C lock failure #1
[2015-09-01 16:52:29] I2C lock failure #2
message at messagedcdc.log I believe the i2c bus is whats directly linked to the controller board, perhaps ur controller board is bad. |

There is no such thing as 2.00 LOG which has those messages in it. Only my firmware will have those temperature thresholds & protection methods mentioned in it. So, Im not quite sure what you are referring to.
If you really are running a stock v2.00 firmware and the log is really spitting that out, then you have something completely wrong.
If you are running my firmware and u did tamper w/ donations then... Im not inclined to support ur issues. This will further force my hand in no donation version even existing, may all end up prepaid only.
On another note the I2c lock theoretically doesnt have anything to do w/ my firmware. Cuz I dont mess w/ that script at all. AFAIK my mods to the monitor script dont mess w/ the i2c bus except for when waas is called which is only if there are die issues.
May be it is my fault and missunderstanding of your donation/payment strategy. I just wanted to try what it will look like if I set a original firmware upgrade.. So I have published that screenshot.. May be you can help me clearing this situation.. So can you explain what is the source of I2C error?? First off, how did u upgrade to my firmware? Did you just do a git pull and call it good? cuz there are further steps to fully install my mod, all of which are taken care of if you flash the .bin file listed on my v99a release. Flash it via the SYSTEM->upgrade section. If all went well as per the output of the flashing process then reboot. Once my mod is installed correctly, or optionally completely reflash the stock v2.00 full img file, either way report back w/ any i2c issues. If they still persist then something is clobbering and preventing the i2c bus from being readable via the pi. Hence causing the lock. |

This screen stays for an infinite time  Waited 3hrs then 5hrs.. internet is 6Mbit and SD 10class NEW one! Please attempt installing the new released v.99a firmware .bin file here: https://github.com/GenTarkin/Titan/releases/tag/v.99aIt wont attempt to install wget anymore, should have no problems with this release. Upgrade should finish in a few mins. Yes  it happened. Firmware flashed. But still no cubes  may be I can find some helpfull info at system logs?? (/var/log/) here is monitordcdc log screenshot  what does these line mean??

So, then the Temperature column on status page is strictly a ambient reading only =)
Well, I would really advise you to investigate markings on all chips on the board and see if any other contains something LM75-compatible. It should be fairly easy and safe to do the tests by touching the plastic cap of the chip with a soldering iron and look for any temperature readout to rise sharply. The continuing popularity of an obsolete chip like LM75 was perplexing to me. Apparently it is still being used as in the last-resort over-temperature protection circuits. When not programmed in any way it will power-up as an over-temp protection set to trigger at 80 degrees Celsius. On this miner it may be wired up to shut it down when the in-cube ambient temperature goes over 80C, which will serve as a sort of pre-fire-protection circuit even if the programmable controllers are hung or disconnected. The firmware source code clearly shows its polling the LM75 IC for temperatures to populate the Temperature fields on STATUS page on webgui. |

Well, my question regarding LM75 is , is it the sensor itself or is it just the IC for a remote sensor probe?
Well, the LM75 physical IC is for sure a local sensor only. On the other hand, if you are looking at the code commented as "reading from LM75" there is a whole bunch of "LM75 register-compatible" ICs that could be using both local and remote sensors. So, then the Temperature column on status page is strictly a ambient reading only =) |
