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 Cool

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 !

Please send me PM indicating what address you sent the email to and what address you sent from. I will see if I received it. Thanks

And yes, what hawkfish said ... applies.

You probably have to send screenshots of your eBay confirmation email and PayPal payment page for verification. I sent them and he issued a free license to me.

Clueless!
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 Sad

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://bitcointalksearch.org/topic/m.14153943

live 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'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.


note: The updated download file is found in your account if you purchased the "FULL COPY"

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 =)

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.

Unless that exact situation can be reproduced more than a few times .... it could have been just coincidence at this point =(
Even then, 2 dies could go down around the same time and there not be any power issue at all. 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.

no biggie, but it obviously wasn't a coincidence in this case, my alarms alert me when the dies fail so I'll catch it sooner next time, now that I know what to look for

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  Smiley

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 :-)

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.

That may be doable, but it requires extremely accurate testing of the DCDC power draw under a bunch of different settings & temperatures. Gathering that data would be the challenge.
Also, way more power gets drawn through these connectors than 180 or even 260w ... @ 325mhz w/ slightly than lower factory voltages ... about 330w is drawn through that poor 6pin connector on Titan side =(
Thats why they went with the Y adapters so each 6 wire cable was at about 150-170w.
I suspect many PSU's breakout panels for their modular connectors arent rated for that type of current @ 12v ... which is where my PSU's cables started discoloring and getting real hot and eventually melting the PSU breakout panel connectors.
I suspect a non modular PSU would fair better. But cant find high effeciency nonmodular high watt ATX PSU's anymore it seems =/
Thats why I was contemplating going w/ the server PSU's w/ the breakout boards made by users on this forum... they are probably much better quality than the breakout boards on modular PSU's.

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.
