ah.....big brass ones you have

Just looked once again at logs and figured out!!! (It's like a glowing lamp nead my head )

Try to folow me:

1. I have a problem with ASIC4 connector. In web it does not show temp! And cube not working.
2. The voltage on one pin ov ASIC4 connector is differrent from others connectors.
3. The 1.04 ver log show continious  Die 3-2 restarted
                                                  Restarting bfgminer
                                                  Die 3-0 came UP
4. Ver 2.00 show I2C error

5. What a stupid guy was I!!!! THIS ASIC4 Connector F#CKs BRAIN to the system board!!! That's why nothing is working!!!!

I am not sure. But if I plug one cube to bad port and one cube to any other port and set 50MHz at Cube on bad port system works continiously without restarts!!!
I need to make some plug for bad port to imitate Cube!!!
Need some advice on that please  

Here is the official answer on my issue

Now system is good working if Cube with no power is plugged to bad port. I need some cube imitator to create

Im also looking for some wall watts vs webgui watts stats too if anyone has them =)
So I can more accurately estimate wall watts stat in webgui.

I dont own a Kill A Watt , but if no one steps up to the plate, then Ill order one. Im sure Steve , MUST have one. LOL

lol, actually I do have one ... what was it you needed?  Total watts used at the wall?

I'll see if I can get some stats out to you

I usually hang out on LiteCoinTalk, so I'm late to the game, but here it goes...

Questions:

1) Is it worthwhile to replace the cheap VRMs that KNC installed with an upgraded version? 
We can buy them here:
http://avnetexpress.avnet.com/store/em/EMController?action=products&catalogId=500201&storeId=500201&N=0&defaultCurrency=USD&langId=-1&slnk=e&term=BMR4641008%252F001&mfr=ERC&CMP=KNC-Octopart_VSE&c=USD&l=-1

But they aren't cheap, and the minimum order quantity is 65.  Each Titan cube would require 8 VRMs at $30 each.  Group buy?


2) Has anyone successfully refloated any of the components on a Titan cube circuit board?  I have tried to do this, and the solder KNC used has an unusual resin (or epoxy) coating on it.  Nothing would stick to it, and it got powdery when it melted.  Either they used really cheap solder, or solder that was never meant to be fixed?


3) The controller boards are the weakest link.  They eventually need to be eliminated, and the cubes need to be run directly via USB-to-serial. 
   3a) Have we tried offering a bounty to anyone who can provide or reverse-engineer the FPGA code?
   3b) I have cubes that will run reliably on all four dies when they are alone on a controller board, but as more cubes are added, dies begin to fail.  This is not a power issue.  I believe it is the RasPi becoming overloaded and failing to properly handle communication with the controller.  Has anyone been able to run a more powerful RasPi, like a RasPi 2 or some variant?

Ditto  have 2 titans running 6 cubes hashing over 500MH for long periods now using the custom GenTarkin modified FW and they run great all the time never crash or need rebooting I have had some SD cards go corrupt on me so just have some good quality ones do a fresh image and use his code much more stable then stock FW

Steve im getting that Hakko FR-300 later today. I have to replace a capacitor and a pci-e port. Ill let you know how it goes. I also want to try to remove the vrms with it.

wanted to download neptune soft for reinstall but looks like the site http://www.kncminer.com/ is down as well as the support files
