https://github.com/GenTarkin/Titan/releases/tag/v.93New release published!! ---details--- Login through SSH & webgui is now: admin/admin (should be anyways LOL! Hope I updated it correctly) =P test it peoples! =) If soft die reset fails then initiate hard reset sequence (power off cube, restart bfgminer) Instead of setting Dies w/ overheating DCDC's to OFF, now scales down 25mhz each check until DCDC's are under temp threshold.. If goes to 100 then sets die to OFF. Added more temps to temp threshold setting, including all numbers between 90 & 95 *default DCDC temp monitoring settings are: ENABLED / 90C ---details--- Please test everyone, Ill fix as issues arise. Please Please donate =) Helps fuel my motivation to continue improving upon stuff =) instead of burning the new img file I tried doing a git pull: cd knc-asic git stash save --keep-index (didn't need this line on all rigs) git pull cd ./update-webgui.sh seems to work but did I miss anything?? everything is upgraded and running fine so far, just a couple observations: -- the temp throttling is sweet, it doesn't even reboot bfgminer, nice!! -- you might want to implement a delay of a few min or so before triggering a hard reset because: a) a soft reset sometimes needs a few tries before it works and this will minimizes bfgminer restarts -- when the rig is rented and the customer is using an unstable pool that takes forever for vardif to adjust & stabilize, frequent restarts are particularly troublesome b) a delay will be needed to optimize voltages & MHz, and/or to monitor which die is triggering the resets anyway I'll send .5 btc to 1Px71mWNQNKW19xuARqrmnbcem1dXqJ3At (sent) thx again, nice work  AWESOME !!! Thanks a ton!!! I just uploaded another change for webgui, it now shows bfgminer version in status screen. Ill look into the delay for ya =) Ill get to working on auto upscaling of cores that previously were downclocked. Have a busy schedule coming up so may not be released as quickly and this is fairly complex =) Regarding the soft reset, do you know where the soft reset actually fails? during the waas -s command or when bfgminer is told to reconfigure...? When u see this behaviour happen can you post the relevant contents of /var/log/monitordcdc.log? That way I can see exactly what needs delayed.(or tried a few times) If I had to guess, soft resets I check to see when they fail the waas command. I base the success / fail of that on whether a hard reset needs to be issued. So, I could do a timed loop of say up to 5 soft resets(on like a couple second timer) via waas command and if they all fail then perform hard reset, the first one that passes it exits loop then proceeds to tell BFGminer to do its die reconfigure. *NOT: The waas command has to succeed before BFGminer will show a "die successfully configured" message. How that sound? no, I don't know where the soft reset actually fails, I get the standard "die configuration failed" message and it tries again 20 or 30 sec later. If I can catch it I'll get the log file. I am using awesome miner to trigger hashrate alerts and can then monitor what's happening, but if the hard reset happens too quickly it doesn't trigger -- it instead triggers the rig offline alert, but then it's too late to see what happened what you suggested sounds good to me Ok, cool yeah "die configuration failed" .. if I would have to assume, means the waas soft reset has failed. At least, when my rig requires a hard reset ... thats the message I get until doing the hard reset. Ill impliment the loop sometime either today or tonight =) If other people could test out the firmware that would be great and any donations helps =) Thanks again for ur generous donation TXSteve, I really appreciate it =) |

A list of changes in my next build:
Proper handling of soft vs hard die resets(if soft reset fails then proceeds to do hard reset via cube power cycling & BFGminer restart)
Custom 92/93C added to dropdown list
A scaling down of dies who's VRM (DCDC) temps cross over threshold
Future build to do:
Add auto clock scaling up for dies which were previously scaled down due to VRM overheating.
sounds great! Thanks =), Im uploading hopefully a working img now. I also changed back the login password to admin/admin for both ssh & webgui *I attempted to anyways...haha will need testing =) Once you test out this build TXSteve, please send .5btc my way =) I would greatly appreciate it =) ... That will get me rollin on auto reupping the clocks of Dies that have been declocked due to DCDC overheat. (this will be more difficult to code cuz now I gotta keep track of original settings n do lots of comparing while running =P ) |

GenTarkin here's the contents of the monitordcdc.log file
[2015-08-11 14:45:08] Start
that's it
I set threshold to 85c -- there was one die at 85c and another at 86c, prior to this the log file was empty
hope that helps
wtf .... weird hrm.... can you post a screenshot of temps & the monitordcdc.log file when it should be going off? Thanks... in all my tests it works just fine ... so this is puzzling   Weird, so freaking weird, maybe I messed up something in bulding my latest .img file. Ill double verify the code works again on my box tonight and make a fresh image. Im also rewriting the code atm to impliment a sliding scale for clocking down the dies which have overheating VRM's rather than just shutting them off =) I may add an auto clock up based on a temp threshold as well. You wanted 92/93C thresholds right? Ill throw those in there as well. I figured it out =) , one of the temp monitoring files I made didnt make it to github, therefore not making it to the img. Sorry =), next build will include the fix and all the goodie updates =) |

That was something we were considering , but after looking everything over, its a really bad idea. Im sure Tarkin will remove that option in the next release.
@GenTarkin. The biggest threat to these miners is the temp of the VRM. I think the critical temp of the vrm is around 85C. Can you put a switch in that will shut down the die @85C , that we can choose to have this active or not, or even better have a drop down to choose the shutoff temp, and a switch to activate or not. I can send more btc if you can do this. This prevents permanent damage to the VRM, thats what overheats, NOT the processors or dies.
Vegas
UPDATE: have a working VRM checker. It basically disables the die whos VRM is over 85. It simply turns it to OFF in webgui and restarts bfgminer. The die can of course be turned back on by selecting a freqency in webgui and reapplying settings. Controlling it via webgui is probably not gonna be an option at least for now. I have no idea how that portion of the webgui code works lol. Will post when its ready for download =) The VRMs enter thermal shutdown at 120C to protect themselves, anything over about 105C is getting sketchy but under that things will make it.. Are you sure? Well, people cast in what they want the thermal trigger at and Ill change it to that. For now its 85C Note donations would be greatly appreciated =) I still have yet to be paid in full for the .5btc bounty =/ I hope you fare better than I did, had hundreds of installs, I helped dozens of people myself, someone started selling it on ebay, etc.. In the end managed 0.32 BTC in total from a few people.. The dozens I helped actually all said they would donate but just needed it working for now, in the end just a handful of honest people. Yeah, its unfortunate, but at least the bounty was delivered upon =) ... back then for you .32btc was worth way much more in fiat then it is now haha =) |

I can check it out pretty quickly
btw, it doesn't seem like the max temp is working, I have it set for 90c and a die hit 92c, nothing happened
Testing a rearrangement & rewrite of hard reset detection. Will have to wait till mine actually needs resetting to see if it works. If it does, it should differentiate between soft reset success vs fail and then applying hard power reset to cube if needed. My Titan doesnt experience successfull soft resets. So, will need someone to test it out once I verify the soft reset fail then hard reset works. It doesnt happen instantly. Think it loops every 4 seconds. Ill test it here in a lil while. I dont see why it wouldnt work but Ill double check =) Grr nevermind, somehow it stopped writing to the config file. Ill have to look into it later. Not sure how it broke =P Probably a typo somewhere lol [/quote] well I had 1 hard reset work flawlessly I'll pledge .5 btc for your efforts, if you can just drop the MHz from 325 to 300, instead of turning the die off. Also can you add another temp cut-off 93c -- I manually turn them down around 92/93 - it's usually at those temps for only a few hours, and haven't had any problems [/quote] Hrm....ok well I found an issue w/ the changes but only as of this morning when I started editing the code again, these erronous edits did not make it into my latest release. I fixed the issues but the release u downloaded should still have worked properly. Any chance you can paste the contents of /var/log/monitordcdc.log when the thermal trip doesnt work for you? It would require ssh'n into the pi and copying the contents of that file to a text file. The test works perfect on my box when I set the temp threshold to 70....(added as a testing temp =) ) I dont even have to hit refresh on the advanced settings page, I can see the dies get turned to 0's that go over threshold, after bfgminer restarts. Also, yes when I have more time, now that I see how KNC updates clocks without needing to restart bfgminer, I will implement a soft clock scale down w/o needing a bfgminer restart. =) I will also put 92/93C in there for ya =) |

it does a soft reset of that one die every 5 min or so. no other problems on this rig so don't need any hard resets or temp monitor because this one runs cool. I'll just run the old img
So, it will remember the temp settings across a reboot as it rewrites the file that checks these temps & settings. Whenever you hit the submit button it permanently changes those settings. As far as handling die soft resets, I think I know a way to differentiate between the 2 via the monitoring script and could possibly modify the code to look for 2 different lengths of time and handle via a soft reset on the short timeout and on a longer timeout make it do the power cycle on the cube. My titan seems to have no soft resets , only hard resets so thats what I modified the script for =)... I thought most Titans didnt actually have die timeouts that were fixed by soft resets. =P How often do the soft resets happen for you. Because, honestly it wont hurt anything by issuing the dcdc power reset thats coded in my firmware, thats if its not happening like every minute or something crazy lol! If its like once every few hours or once a day, then the hard reset in my firmware is still just fine. [/quote] [/quote] Testing a rearrangement & rewrite of hard reset detection.

my question is how do you handle the soft asic resets where it comes up 1a NONCE received whatever the msg is ..and eventually it fixes its self promptly after
maybe saying the same message in 4 lines like 1a 1b 4c 2d or whatever?
I have one die that does these soft resets quite often, half the die is working the other half isn't. So I tried the GenTarkin upgrade and it changes these soft resets into hard power down/up resets, so it's probably not what you are looking for on that rig. I switched back to the old img. I am using GenTarkin img on my other rigs, and it is fine so far. Haven't had a temp trigger yet but I expect at least 2 dies to trigger over 90c today, see how that works GenTarkin do we need to enable the max temp each time we start the rig or just once and it remembers on subsequent restarts? Steve ps here's the soft reset msg sequence [2015-08-10 16:33:33] KNC 4b[5:1:369]: Got nonce for unknown work in slot 0 [2015-08-10 16:33:33] KNC 4b[5:1:370]: Got nonce for unknown work in slot 0 [2015-08-10 16:33:33] KNC 4b[5:1:370]: Got nonce for unknown work in slot 0 [2015-08-10 16:33:33] KNC 4b[5:1:370]: Got nonce for unknown work in slot 0 [2015-08-10 16:33:33] KNC 4b[5:1:370]: Got nonce for unknown work in slot 0 [2015-08-10 16:33:33] KNC 4b[5:1:370]: Got nonce for unknown work in slot 0 [2015-08-10 16:33:33] Pool 0 stale share detected, submitting as user requested [2015-08-10 16:33:33] KNC 4[5-1] Die configured successfully not sure how to detect these soft resets, maybe just run the hard reset routine at a set interval like every 5 min -- that way gives the soft reset time to do its thing So, it will remember the temp settings across a reboot as it rewrites the file that checks these temps & settings.

Guys we are on our own as far as firmware updates. We are so fortunate to have someone that can help us. I have donated some BTC , but if you want this development to continue , then please donate. I LOVE the 85C cutoff for the vrms as they should NEVER get this hot and if they do, and run this way or hotter, they will eventually burn up. Nice work Tarkin!! I have made major improvements on the hardware to reduce the heat as much as possible. I will be offering my service to the public in the next few weeks. This is a pic of one of my cubes that has all my mods. There are 7 different mods that needs to be done to achieve this, and its nothing I will discuss here, youll have to send in your cube for repair and mods. Or I can offer a package price for multiple working cubes for just mods. This is a cube with all the completed mods running outside in Las Vegas in over 105F simply to test it under the most brutal circumstances. It has been running for over 12 hours. I set the last 2 dies at 325MHZ on purpose just to see what the temps would be. Here are the results:  To my knowledge I am the only person who is not only able to repair these , but also at the same time get such low temps. The vrm temps is what kills the dies. When this is prevented, your cubes will last 100X longer. I would strongly urge anyone to have me perform these mods BEFORE your dies burn up, especially if your vrm temps (to the far right) are running at 80C, its just a matter of time. Here is the link to my website in case you want these mods applied. I will also make a video soon and post it on youtube for any doubters. These hardware mods work VERY well with the firmware from GenTarkin. http://bitcoinlasvegas.net/kncminer-titan-repair-knc-miner-repair-titan-repair-kncminer-fix/Vegas Awesome job man!!! impressive! =) |

Instead of turning an overheated die OFF, how about just bump the MHz down a notch, say from 325 to 300, no need to turn them off we have some 100 degree days coming up and I will likely have to bump them down manually I haven't tried your firmware yet but likely will thx for your efforts UPDATE:
New release v.92
Ability to set DCDC temp threshold on/off & temperature via webgui.
NOTE: due to having extremely minimalistic webpage coding skills... the values shown on page DO NOT reflect current settings.
Its ok to update DCDC settings as many times as needed, the BFGminer is not restarted or interrupted.
Need to refresh ur advanced settings page for it to show =)
Ill consider it. I gotta say, at this point... Ive put a ton of work into this and not many donations have been rolling in so .. my motivation to keep improving is nearing its end. I dont even need VRM protection on my titan since it runs really cool. Was a feature someone asked for =) Anywho ... Ive gotten paid the original bounty now and brought more to the table then the bounty asked so, please any further donations would be greatly appreciated =) Ill keep ya posted as to my next update and if I get the sliding scale clocks for VRM protection implimented =) |
