As above fully working KNC Titan controller/bridge. Location - EU preferable, with or without cubes. Leave offer with price here or PM

after i tried couple things i was able to run 5 cubes on one titan. I flashed sd with factory 2.0 then i upgraded to 1.0.4tarkin and restored to factory settings if i remember correctly otherwise it had problems with starting all die's and fell in the restart loop. Upgrading bfgminer occured some problems so i didnt do it this time. I was wrong when i thought that 5.4.2 fixes the asic temp missing.
I will try further with other units. Meanwhile probably one of my 2000BB burned/overheated while running 5 cubes.
So, I was wondering ... is there any chance you can try loading an SD card w/ KNC2.00 -> KNC2.02 -> my firmware 1.0.4 and see if it works? I dont have a Titan physically, so its very difficult to test the version combinations =/ Im confused as to what you said doesnt work... did KNC2.02 come loaded on the miner when you received it and u flashed my 1.0.4 ... then it did not work? Or did you mix my bfgminer5.4.2 installer in there as well? Cuz, KNC2.02 -> GenTarkin 1.0.4 should not cause any problems ... even if it did , it should be clearable w/ the factory defaults options. I would like to just figure out what all happened. Or ... maybe its just bad luck and all variability / coincidence ... that would seem to be Searings experience =P they all came with 2.02 installed on sd's. I will try 2.0->2.02->1.0.4 later aswell |

oh they did test them believe me to each unit they put print from test, and yes the dc/dc from die 2 mostly run hotter and look in some cases worse than others. I already replaced thermal paste on all of my units that was first of my steps, then i made my own brackets and installed radiators on each dc/dc. Altho all my units seem to be assembled out of "new" parts, including fans, boards and all. I got only one cube that was running much hotter than others (over 80degrees) but repasting, sinks and noctua cooled it enough. If i wont be able to run 5 cubes per controller i will eventually give up and start looking for additional controllers to buy and run the rest of cubes. So far i got 6 cubes remaining to redo all of upgrades due to lack of time

One thing you guys could try is setting the Titan to factory defaults on SYSTEM TAB and ADVANCED TAB after upgrading to my firmware when using more than 4 cubes on the controllers. Perhaps theres some configuration bug somewhere. But my firmware works fine w/ pre 2.02 builds and more than 4 cubes so not sure what the cause of the issue is.
Like I stated, its likely theres something far different in KNC's stock 2.02 firmware thats not on their github version of it and my firmware is overwriting it. If thats the case and everyone upgrades (meaning theres no stock image left) then I cant start anywhere w/ fixing it.
Have you guys looked at controller or bridge boards and see if they have different versions between the old Titans and new(old stock) ones you guys got??
Also, their knc2.02 linux version may be different and that adds another variable as well.
I still have yet to receive log files from anyone.
Got so little time as im working dayshift, i will try to do as much as i can today, and send You logs. If You want i can make img of this stock 2.02 and put it somewhere for You. |

For anyone having issues w/ KNC 2.02 packaged Titans received from KNC lately. Please email me the logs using the save log button on ADVANCED page. Use the links on my website http://gentarkincustomtitan.pcriot.com to email them to me. Also, it seems to be a pattern of unplugging one cube makes it magically work?? If thats the case, how many cubes are you guys using per controller? Also, what version of my firmware are you trying to use on your Titans. My older copy of v99e most likely wont work, because it overwrites a lot of stuff thats in knc2.02 w/ older files. The newer version of my firmware 1.0.4 should work as shown by Searings experience. So, if you are using my older firmware ... it will be time to upgrade or stay stuck on stock KNC 2.02 PM sent |

edited my previous post..
actually it is perfect for my rig with 4x pcie, a 2kw psu can handle 4x 390/390x or 490/490x (when released) at full power.
i just want to assemble and simulate everything in my mind before making a decision.
actually it can handle even more, atm my 4x390x mining etc/sia pulling 1350W from the wall |

Now both show up in device manager and wattman but only gpu0 is detected in Claymore.. tried 5.2/5.3 and crimson 17.6.2/3.
Have virtual ram set to 16gb.
What am I missing?
turn off crossfire you use -di parameter in batch file? |

easy to check if its powered usb riser problem or mb, just connecto 1 card through powered riser to x16 slot if it works its not riser to blame
also if its corsair then it has one 12v rail so its good
and just to be sure in device manager You have only 1 gpu present? rx480, no integrated

So who do i call to get those boards or the 4k BB packs in EU? I need to power up knc titan's so i need those plus small atx i suppose to power up knc controller
|

|

Are they powering up at least? What psu are You using? Did You turn off integrated gpu ? If You try unpowered risers then power up MB with molex

While all the usual ETH pools now offer ETC.... cant help noticing that ethpool and ethermine, is not doing ETC.
What is the most stable ETC pool, with payments so far?
https://ethc.coin-miners.info/works for me so far |

myself and friend were able to rip out from their claws 10 of those "unicorns" as You call them altho shippment for us is like 400$ and most likely we aint gonna sell them unless someone offers insane price.

Have you tried swiching to PCIe x16 Gen 1.0 speed in MoBo BIOS?
Or more likely: Do you have Aero enabled or disabled?
i tried gen 1 and 2, all visual effects in win are off, no change |
