I bet, making the Y connectors into 3 way Y connectors would definitely drop the strain on the ATX cables =) That would drop the watts per cable down to about 110w.
I suppose. However when someone puts a cube on your doorstep that did this: You wonder if that cube plug is just a limiting factor. Ultimately it's up to everyone to do what is best in their circumstances. :-) Yeahp, in that case it is the plug, I think overall the plug / connector is at a max of sorts too... Molex designates that specific PCie 6pin connector to only be able to handle 12amps. We are pulling more than double through it.

Well, these two units are currently running approximately one (1) inch away from each other, so the environment is pretty constant. The difference between the two is the difference between an average DC-DC temp of
ASIC slot Temperature DC/DC avg temp Clock Type 1 --- --- --- OFF 2 32.5 ℃ 47.4 ℃ 225 MHz TI 3 --- --- --- OFF 4 --- --- --- OFF 5 --- --- --- OFF 6 41 ℃ 62.0 ℃ 275 MHz TI
Which is pretty big for that extra 10mh.
You mentioned that your power supply cables melted at least once, and I just saw a picture of a guy's power supply that basically started to set fire to his house. Glad his house did not burn down, but the problem was the same, power supply cables melted. Fixing melted units that blow the PCB connectors is a real bear and I just got a Neptune in that had a blown power cable that led to a short on pin 6 (this time to the .7 line which allows it to work, but very weird) which proves board burns can damage other Neptunes and Titans due to the lack of signal isolation on the controllers and/or the units.
Perhaps a good code release would be a "do not pull more than X watts from the supply lines" so people could put in 180 to be nice and comfortable up to 260+ if they really want to see things go foom or something. As always I stand by to fix the blown cubes, but it would be better if they didn't blow in the first place.
well if a blow up a cube I'll give you a try to fix it, so far they've been running pretty good but have to do maintenance on them as needed: clean, replace cables, y connectors, capacitors etc btw I fried a 6-pin pcie connector today, I could barely get them unplugged. I used someone's idea on here to use side-cutters and cut the plastic away, just leaving the 6 pins on the pcb. I cleaned the pins as best I could and it worked great. So much easier than desoldering & soldering a new pcie connector. I have replaced 2 pcie connectors in the past and it so difficult, that solder is tough, it took hot air & a soldering iron to get it hot enough, a real pain in the neck. Thx whoever posted that little trick, worked great and saved so much time & aggravation I fried 2 y-connectors & 1 pcie connector this week, but it's been a long time since any problems so that's not too bad Your Welcome :-)

POLL: Based off of ... I believe lightfoot's recommendation ... For my next release, who would find a "cable / connector life saver" option valuable? Basically it would be an algorithm to guestimate how much power is being drawn through each PSU cable assuming the Y connector & 2 PSU cables are present, per cube. The algo would then take into account current draw per DCDC & overall watts & possibly even temps guestimated by the cube and then drop the clocks down until the power usage would be below 140-150w per cable coming off the cube. This would of course make the Titan slower but far less risk of burning cables.
I really dont know how valuable such an option will ultimately be, because I know most miners just want to push these things as hard as they will go and when stuff does burn up, just replace and move on. So, may be a lot of work for nothing really. But its an interesting idea =P

I have noticed that when multiple dies fail at the same time that this is a great signal that there is a power problem. I have alarms set when mh/s drops below a certain level I can manually monitor the advanced page. On the last alarm 2 dies failed at the same time, on the same cube and your firmware soft restarted them. A few hours later the whole cube failed because the psu shutdown so I checked the cube and discovered the fried pcie connector. And this PCIE was seriously burnt, there wasn't much left of it, the male/female were melted/fused together, I needed pliers to separate them. In this case restarting the dies earlier certainly didn't help. So maybe some logic that when 2 or more dies fail at the same time just shut the whole cube down till it is cold started or rebooted. I don't know if or how often this would generate false alarms, but I've never noticed 2 dies failing at the same time except in this instance.

Ive witnessed it several times on my Titan. But, a definite pattern of many different miners would have to prove this is the case before coding this into the firmware.

STATUS: My host is apparently having issues today, site connectivity is intermittent. Figures I would have problems right around the time of release =/
Sit tight everyone. Sorry for the downtime. Im just waiting on my host. =(
UPDATE: site back up for now, its just been really intermittent. So keep trying every once in a while =)

GenTarkin's Mod ~ Custom KNC Titan firmware v1.0.2 RELEASE NOTES - maintenance release
-Fixed an issue in regards to user specified api-allow settings in "manual edit" mode. Its a bug thats been around since v99e and someone just pointed out to me. Basically, the "API readonly checkbox" was overriding any user specified settings for the api-allow entry. Now, when user changes this line the "API read only checkbox" setting is ignored until the api-allow line is restored to its original setting OR its removed entirely.
-Activation: due to an unforseen situation regarding activation, the manual method of reactivation was not working as intended. This is now fixed. For any miner you try to reactivate w/ its respective(matching license) it should reactivate w/o issue now.</li>
note: The updated download file is found in your account if you purchased the "FULL COPY"

well off topic sort of but people due ask about ltc equip on here for sale anyway a top (1 of 4 only) the top tier Administrator Accounts on www.litecointalk.org was hacked .the account name was Carnth and the newbie accounts as well. So if you have the same password on bitcointalk here I would change it along with the one on litecointalk.org Anyway made a lot of good deals on both litecointalk and bitcointalk w/o issue (100mh of titan cubes on litecointalk with another guy last week no issue) but them days may be gone I guess anyway here is the link on another thread I made for this sad tale but main point on here if you are using the SAME password for both sites...change them. IMHO he had the highest status you could have on the litecoin site....I'm sure there will be a lot more folk with issues then just me. Again with such powers the whole site could be 'dorked' anyway the thread about such on here https://bitcointalk.org/index.php?topic=1393491.msg14153943#msg14153943live an learn I guess at least I just lost 2 weeks of mining to get the 110 ltc rather then 'gasp' paid $$$ for that 110 LTC ....that would have hurt a lot more. anyway live and learn..onward and upward....dare to dream be the dream and whatever 'rationalizations' I can use to get me past this..sheesh...... edit: www.litecointalk.org the site is down today so hopefully they are re-doing the site for better security or with the powers of the hacked account the hacker flushed the forum we will see I guess..hopefully they are just re-do'ing stuff cue to the compromised administrator (the top level of accounts) is being addressed etc etc

GenTarkin, in november (30/11) I've purchased your 0.99e firmware on ebay via bitcoinlasvegas.net. It works great on my Titan, no more babysitting for it A few days ago, I sent to you an e-mail to have access to your new firmware on the new shop but I didn't receive your answer. I know that I am an "unverified customer" and I read the problems with bitcoinlasvegas and you, but I would know if you can give access to the new firmware to the customers in the same situation. Thanks for you great work !

Hey guys, quick website update: So, for some reason permalinks broke which caused every page to not work correctly except homepage =( On top of that seems there are intermittent connection issues every once in a while. I dont know why my host has gone to shit in the last week, Im hoping all this pans out. Anywho, should be working now. I restored default permalinks ... those work. But any external links to specific pages on my site wont work till my host fixes their issues.
This is such a PITA that my host has all these issues at this time lol! of all times! =/

Pictures of board: HOLY SHIT those 2 dies got way way way to fucking hot. Most likely fried the package substrate or something along those lines. If its not working, that would be why. I really wish KNC would have designed the dies with ondie thermistors. So we knew what the fuck the actual temps of the dies are... Yeah I was thinking that. When I say I have seen burned titans this is what I mean... *However* (and here is the magic however button) the chip itself doesn't have any of the +12v lines going to it. Therefore it should not be crowbarring the supply. It could be a blown FET on the power supplies, or a blown cap that's not showing up, but it's not just the chip. The chip has the .7 volt supplies going to it, some SPI lines one for each quadrant and the jury is still out as to what else it does. ITS ALIVE:))) Thanks for fixing it buddy.

Maybe this was mentioned already in this 2000+ page thread but Im going to ask anyway... Is there anyway to dynamically adjust the fan speed? These miners are actually fairly quiet but being able to knock them down manually or auto adjust based on temp would be a nice plus. Note that Im a new Titan owner so maybe this is common knowledge and I just lacking it.
EDIT: Thought this was GenTarkins thread, but I guess the question fits here as well...
