While we are on the subject, has anyone been able to solve the issue with the "idle die". KNCminer SWEARS its because the heatsink is not tight enough. Out of the 13 cubes Ive tightened the single screw nearest the exhaust , Ive got 1 cube to work correctly. Its ALWAYS the top two dies #0 and #1. They "idle" at .8v, has ANYONE found a way to get these two dies to work again?

Um if you mean by idling dies when the dies drop off and no longer mine? Thats exactly what my firmware "bandaids"
My firmware shuts off the cube w/ dies that have gone missing and then powers it back up. Restarts mining as needed.

Just to be clear all this upgrade does is if you have a die stop it will restart the particular cube ..do I have this correct? or is there more to this then that

In that the cubes I have with bad dies they are shut to off (never got them to go at all) this patch may not be needed for someone in my situation

I probably should copy it and set it aside thou in case i have the phantom loss of die issue every other day i've heard some titan owners have

anyway just asking about any other reason to try your version out

Someone know why the fuck i cant access the advanced setting on my titan batch 2? Is there something special to hit to start hashing once all info are completed ? Im not able to mine and a isee my 5 cubes Sad

[vegasguy]

This is for batch 2 titan correct? The factory voltages are much higher on batch 1 titans, so if this image is for batch 1 , dont apply to batch 2 titans or it will fry your cubes.

Where are you getting the idea that batch 1 runs at higher voltage? It doesn't. Stock is -0.0366v.

[vegasguy]

Thank you, I thought somewhere I read that, but I was incorrect.

Thanks

The last time this happend to me it was a bad micro sd card

[vegasguy]

Im still talking to Kncminer to see if I can get my cubes RMA. I just sent them a message to see if they will agree to the following terms.

I have 13 bad Titan Batch 2 cubes , about 8 of them have bad/idle dies that sit at .8 volts, Ive done the fix were they have you put a longer screw through the single screw near the exhaust, and put a nut underneath and of the 8 I tried this repair, none of them changed. I have 5 that have melted PCI-E connectors. So, Im under warranty and even sent them the email as proof. Ill report here on the results as they have informed me they watch this thread. 

I told them I would try and fix as many as I could, this would involve my removing and cleaning the melted PCI-E connector and cleaning it. I did this on one that was not working and now it does. So I proposed to them that I fix as many as I could , and the ones that didnt work they would RMA, even the ones that have the melted PCI-E housing removed. Lets see what they say.

Correct, if you have permanently damaged dies that cant be fixed as a result of powering off the miner and powering it back on... then this patch will do nothing for you. But if your dies randomly drop off while mining sometimes and a power cycle remedies the issue temporarily then ... this mod will do the power cycling of the particular cube having issues for you. In other words u dont have to baby sit the miner.
Also my mod adds way more useful stats under the STATUS webgui.

Well, as far as I know my titan is a B1 and its stock settings are -.0366v @ 300mhz
Ive deleted the advanced.conf in the image(firmwarE) and Ive tested this does indeed restore the miner to default factory settings(clocks & voltages).

GenTarkin,

I just tried your image, but the default login and password is not admin/admin so I couldn't log in to the Titan. What is the proper user name and password for your image?

Any better performance with these firmware?

Any better performance with these firmware?

Please go back through like the last couple pages of this topic and read everything Ive mentioned.
Again, all this firmware does is bring "dropping dies" "sleeping dies" "braindead dies" ... or whatever you wanna call it.... back to life by automatically power cycling the cube that has the dropped die.
I also added more stats to the STATUS page of webgui when you log in.

I made this firmware primarily because of all the complaints about titan owners constantly experiencing dies that stop mining and they have to power cycle the whole miner in order to bring them back up. I experienced the same issue and had a feeling that the DCDC's were programmable and therefore could be issued a command to powercycle themselves and hopefully bring the die back into an operational state w/o any interference from the operator. It was successful and hence I decided to make my own release =)

Future changes may be an updated bfgminer and ability to OC to 350mhz, but Ive seen nowhere on how to do this. I do see some areas in the source code provided on KNC's github that MAY affect clocks but I dont know if simply adding a 350mhz value would do anything at all. I would like to see working documentation or examples of this from known sources OR from KNC's other products and perhaps I can figure it out from that.

[Prelude]

Thanks for your efforts so far, GenTarkin.

In my case on a Titan with 3 dead dies, the firmware was unusable as it would continually restart BFGminer even though the offending dies were set to "OFF" in the advanced page and all other working dies were hashing.

Are you sure your changes are rebooting individual cubes and not the whole shebang? From what I understood observing through SSH, what was happening was a restart of BFGminer and all 4 cubes if there was not 4 working dies per cube.
