"autotune" continues to edge toward a testing release =) .... weeee!
Oh, also in the next release will be "DCDC overcurrent protection"
If any DCDC's are running over 46A, it will issue a hard reset to that cube first time, 2nd time if its still over 46A ... it will clock down that die to 200mhz to alleviate load on the DCDC.
Reason is, I ran into a weird behaviour w/ one of my cubes this weekend, noticed one of the DCDC's had dropped and the other DCDC for a die was taking FULL LOAD for that single die! It was pumping out 50A(horribly so I must say, it was in throttle mode) ... the affected die was at like 40% HW error rate because half of the poor die was effectively not working cuz not enough power to feed it.
This is a dangerous situation for the DCDC's .. so I coded up the above protection =)
God damn, these things are literally RANDOM AS HELL! LOL!
Haven't seen that one yet, hope I never do So did it recover? Did it need a hard reset? or Cold restart? Issuing a hard reset to the cube brought the DCDC back =) Hence thats why I coded up a hard reset first, followed by underclocking the die if needed. |

POLL: Anyone here actually run their a cube at 325mhz @ -.0366v setting and it has no issues doing so?
Er....been running all my cubes at 325 for months now (except for 2 that were set to OFF the first month and recently had 2 dies (on cool cube not hot die ones) set down from 325 to 250 and 275mh receptively (summer may try to up them again now that winter in my bsmt) (my setup lostgonzo.imgur.com) Perhaps you meant 350mh setting mod instead of the 325mh above? 325mh setting on the adv page is quite common. At least that was recommended as 'suddenly' ok on the 2nd or 3rd firmware version ...when I an others reported bad die issues (and thus the 'new' policy if set at 325 on adv page all cubes and you can get over 300mh KNC does not have to RMA squat.) oh my titan(s) are both NOV 2013 units. My orig Titan's warranty (such as it is) will run out Nov 6th I think it is. Soon to doorstop afterwards I'd guess  (re-read the above you must have meant 350mh settings mod on adv page?) Nope, was asking about 325MHZ!!! not 325MH |

This thread makes me sick, KnC Fucked the community over and you scum bags support them!
Fucking blind, IGNORANT sheep!
Did you sell your titan(s) on ebay for $2000?? Nope, I didn't touch them with a barge pole because im not a fucking idiot! Correction, An idiot is someone who does not know law, I should say stupid! As for you other fruity loops, YOUR STILL SUPPORTING THEM! And they were bad from the start and this was ALWAYS the plan. Your the mugs with it written on your heads, Not me Hahaha You do realize that the Titan is one of the only profitable scrypt miners if you pay electricity.... Thats why Im making them run better w/ better firmware =) whos laughing now... |

POLL: Anyone here actually run their a cube at 325mhz @ -.0366v setting and it has no issues doing so?
I've always run all of my dies at 325mhz since it became an option. I run some at - 0.0366, and some at lower or higher voltages if needed to maintain stability. Why do you ask? For my autotune algo tuning. Im thinking of having the highest a die will be set to is -.0366, any higher @ 325 will cause the VRM's to run way outta spec and I want to avoid that. But that means anyone that actually runs them higher than that and needs to to keep a die stable, well autotune may not work well in that case =) Good news is, last night was the first long term test of my autotune algo, I set all frequencies to 325mhz @ -0.0439v and it successfully tuned all my dies to nearly *NEARLY* the exact same settings I can achieve by hand, the power consumption ended up being EXACTLY the same as my hand tuning, maybe even a couple watts lower. The autotune did this in a matter of hours =) WOOHOOO! A couple of dies it could have tuned better ... but I think this all comes down to how long I set the hw% error window size. Larger it is, more accurate the reading is. Last night it was 45min windows. I may try for 60 or 80min windows, next ... just takes longer to test.. But the basic algo works =) |

I just started using .99e
BUG?: I had to specify ENGLISH for the language more than once.
Feature request: Since multiple pools can be specified, it would be great if the Status page showed you what pool (or pools) your miner is connected to. Obviously this has always been a problem since KNC's original firmware.
99e, so far, so good.
Hrm.... I dont know where that bug came from, the code for that is pretty simple. It sounds to me like maybe the firs time it just failed to save the preference to the file for w/e reason =/ ... so far noone else has reported this issue. I can try to add that to a future release for the pool info readout on status page. |

Thanks to KNC miner I got both of my controller boards working again, damn EVGA power supply literally smoked my boards, not knowing the cause of the issue I sent both controller boards back to KNC they repaired them sent them back and poof the damn power supply smoked my raspberry pi. This time I used a new power supply and luckily it only smoked the raspberry pi this time and I needed to reflash the card with gentarkin 99d and I was back in business.
Cant wait for the new 99E.
BTW Is everyone here on Prohashing.com ? Seems to be the best pool I have found for SCRYPT mining.... thoughts?
Dont let that secret out!!! LOL jk =P yeah I switched to it a week ago, the titan absolutely loves it. Best pool ever! |

UPDATE: will be releasing v.99e within a couple days, maybe even today =P
Features will include:
-groundwork code for multilanguage capability in webgui. Upon reboot after installing upgrade it will ask which language you want the webgui, only working & complete one is English for now
-chinese skeleton site, only includes the status page translated
-much more accurate wall watts
-ability to set your PSU's expected effeciency in SYSTEM tab which is used to calculate wall watts(defaults to 85%)
-more accurate cube power consumption in ADVANCED tab
-more modular code in monitoring script(which will give way to autotune someday =-) )
Future release:
Since I have the code in place to deal w/ the config file for voltage & clocks now, I will start coding some sort of autotune sometime =)
Im thinking initially it will only adjust voltages up and down a few notches by monitoring HW% error rate for each die in bfgminer and adjust voltage up/down accordingly. The maximum hw% Im gonna let a die have is 1% (overall hw% no greater than 2%) (based on my titan) .. Im not sure about the overall range of die hw% quality out there so a lot of this will require people willing to test the autotune.
Best(desired) clocks will still be required to be set by user.
There are lots of stuff to consider when tinkering w/ voltages automatically, such as per die DCDC current draw, per die DCDC temps, overall cube power draw, HW%, etc... this could get really complex really fast which is why Ive been putting it off =-P
Looking forward to the update! In regards to auto-tune, that's a good idea. I've done the tuning myself manually, also aiming to have no more than 1% HW errors per die. Once that's dialed in, I leave putty connected in screen to monitor for bfgminer restarts due to dies being un-restartable with your watchdog. When that happens, I bump the offending die's voltage a notch until it's completely stable. That leaves me with a 100% stable Titan at the lowest power consumption possible. Here's what that looks like:  That's mining on nicehash in case you're wondering. Very nice =) , yeah my titan is a bit picky, I have one die that has like a 2% rate no matter what voltage, I imagine there are others out there w/ the same situation, so those dies will be hard to account for. Ill have to code in something where if it keeps raising voltage w/ little hw% change then it will just revert the voltage to where it was... somehow lol New firmware may make it out today, or tomorrow. Im awaiting test installs on someone elses titan. If anyone wants to volunteer shoot me an info. For those who have my btsync share , the release is already in there. Test as you please and let me know. Its so far, appeared to install fine on my titan, although since its my dev environment, its a bit different then everyone elses =P |

Hey I had a thought...has anyone been crazy enough to 'water cool' these Titans or Neptunes...that would be cool (and likely expensive) but man that would be a cool youtube video Dumping that sorta $ & time into a project like water cooling titans .. is rather pointless and a waste lol! Would have to make a custom block just for the dang VRM's and the ASIC. I dont even know if the ASIC runs that hot. It consumes about 250w overclocked, highend video cards consume that much and have smaller heatsinks and are cooled just fine. It would be nice to know the actual die temps of these things....guess we'll never find out LOL |

Gentarkin, great job on the software btw, I am one of your donators you mention current above 40A being an issue can you make your software keep the settings in a "safe" range etc ? I could but it would be largely pointless. Being a tad above 40A is not as dangerous as running these things at temperatures for which they arent rated to handle 40A. So, I think temps are much more important then going over the 40A by a bit. Hence, I would recommend the max temp of my DCDC threshold code to be set to 80 or 85C. |

BTW, heres an interesting tidbit for yall, I think why many titans "dies end up dieing permanently" are infact because the DCDC modules burn out. After looking over the tech sheet, its easy to see why. If the ambient temp (surface temp of the inductor) reaches the 80-90's these are only rated for 25-30A to maintain their expected lifespan.
The fact some folks run them at these temps 24/7 and draw over 40A through them, its easy to see why the DCDC's would die ....
When vegas measured the temp of the inductor from the side, it measured about 55C , the webgui showed about just over 60C ... so there is a really small delta between the ambient temp & internal junction temp(webgui reading) of these DCDC's
Meaning, if ur webgui shows 90C area, the inductor is probably not far behind, most likely running in the low 80's ... which means nowhere near 40A should be pulled from the DCDC at that point.
What would be the safest Maximum DCDC temp setting on advance page of your mod regardless of the ambient temp? I currently set it at 90 and all dies run at 325, should I lower it? Ultimately its up to the user and their preferences of how long they want the machine to potentially last. Its hard to answer ur question definitively due to so many environment variables & operating conditions between cubes. What everyone needs is a laser temp reader to take temperature checks of the inductor on the DCDC modules while its hashing. If its true that the inductor is generally within 10C of the webgui stat then a SAFE MAX temp @ 40A is... between 70 & 75C, so webgui stat should no higher than 80-85C. Whats interesting is with more airflow these DCDC's are rated for more current safely at any given temp, even if the temp is the same vs less/no airflow. For example, temp of inductor 80C @ no airflow is safe up to 34A. 80C @ 2-3m/s of airflow is safe up to 40A At 100C inductor temp: 20A safe for no airflow, 30A safe for 3m/s of airflow Another facet of max life from DCDC's is keeping them at their rated 40A max or lower. I know most of mine in the titan @ 325mhz are at 40-41A ... which I imagine aint bad, but I think around 43A ur starting to really push it. The actual Current limiting function of the DCDC's kicks in at 46A This is the life expectancy of the DCDC's given everything is within spec: MTBF at 90% confidence level = 11.52 Mh So, safe bet would be to keep DCDC amperage at 40 or below if I wanted the cubes to last longer? I see at 325 some of them goes as high as 44. Heh ..not even gonna look ...I have one cube with 2 dies runs hot as hell always has 325 mh all out.(since march 2015 when I got my 2nd unit) .....i always expect it to burn out ....looked yesterday 90c plus as per usual that was when I got the used unit...so all the cube goes full out.....at max 325 setting any other cube i throttle it back (or titan says no way) looked today 100 to 101c on the 1 die chugging merrily along...I am befuddled as always ..so that is what 8 months of full out wtf is going on ..then again it has been 11 months wtf is going on with the dies I have set to OFF its only fair I be confused the other way around so again confused on what witchery is involved in this tried to tone it down last march the die would not come back and previous attempts..but ..put it back at 325 setting etc and viola bat out of hell since (highest producing die too ..heh figures) so i only have 2 weeks left on my warranty so it will blow up 2 days after but man i'm clueless as hell on how just plain 'weird' these units act from my own experiences and the folk's on here saying stuff So I'm trying to go with the 'idea' (likely) as best I can recall in them 'heady' months when the Titan was expected to arrive on time and such It was designed for 250mh .....the dc's etc components (power jacks) etc etc with the 'appropriate' over engineering for that 250mh unit They figured out before shipping (w/o telling us imho) that the units were probably gonna ship late....so upped the hash from 250 to 300mh to compensate for the lateness i suspect they saw coming (although to be fair I doubt they thought they'd be as late as they were) Again still within the likely 'over engineering' on a 250mh design They shipped......1st batch had bad dies..the firmware sucked with lots of errors etc...Initially I was told to mine at 300mh anything above that was my own risk...the firmware ...buggy as hell for 2 months plus was not helping hash .even with LTC ...the hardware had the bad die issues..thus suddenly when I had 2 bad dies on 2 diff cubes ..I was told to overclock it to 325 speed on adv page (ie ok by knc techs) so I did and it worked ok (with 2 off dies) Side note: By the way I seem to remember the 1st firmware you could not even SET the speed above 300mh or am I incorrect? Anyone? But then they changed the rules and said because my orig titan got 306.1 mh with 2 dead dies anything over 300mh they would not take back equip and nor any cube with only 1 die off.....amazing how rules got changed. Again this was against their previous advice of 300mh was max. So essentially to cover their ass on shoddy firmware and equip and lateness of shipping you were 'required' to overclock.... the F*ck out of your Titan to get around their failed design/promises and ship date..thus burning a lot of stuff out early as you can see from the 'wreckage' of this thread over the last year or so.....all risk on us! to get to my POINT: IT IS IMHO A FRIGGING MIRACLE THAT ANY OF THESE TITANS THE WAY THEY WERE DESIGNED 'MANAGED' TO GET ABOVE 300MH FOR A YEAR! I JUST NEED TO DEAL WITH THAT 'REALITY' (ie KNC lied on what the product should do vs what it could do) So trying to go with the flow...they are frigging overclocked to the max at 325mh adv page settings..so it is easier to limit my expections to reality then to try to figure out how to tweak these units above 300mh when they already are in 'flaky mode' at probably 300mh ONLY ..from what they imho were designed for! Got to admire that KNC 'evil genius' chutzpah thou! We have all the issues/risks/etc and they limit their problems with these units by a lot! By the By I have 2 weeks left on my warranty ...anyone want to use me to swap a cube out to knc for their 200 bucks I'm trustworthy enough to do so (then again with 2 weeks left they may just never send it back claiming it did not arrive even thou on the shelf..ie must remember the 'evil' we are talking about) But we should have a mechanism on here to move cubes back thru trusted parties for folk who's warranty has already run out....I mean its not like they did not play such games with us..the old razzle dazzle misdirection tricks... (then again send cube 200 buck fee....in say a month the knc tech is fired (or quits) due to his impending loss of a job...as the 12 month fix them requirement goes away) hell probably should just send them to Vegas would be safer I guess ..just frosts my cookies for those with cubes as door stops as we speak because it is already past 12 months and they are stuck......whatever just wool gathering on above At those temps Im surprised ur DCDC's have lasted as long as they have. Also, those arent DIE temps, there are no die temp measurements on these Titans, those are just internal temps of the DCDC's. There is absolutely no way to detect internal temperature of the dies on Titan. Unless they have an undocumented thermistor somewhere in there LOL! ~ I doubt it. Also, I have no idea what these units were originally supposed to be rated, but perhaps they were all supposed to be 5 cube units all along and they decided to take the cheap way out by shipping 4 cube units and telling everyone to OC. And yes u are right about early versions of firmware 300mhz was the max, the allowance of 325mhz is shown on github as a change to the spimux-titan.rbf file. Which is why I know the key to unlocking 350mhz is in that file =) |
