Looking for some Ideas
Gen 2 blade GREEN issues:
I am now more perplexed as to what is the issue with my blades.
I now have 2 blades, both are using power supplies with well more than the 8.3amps on 12v that is needed triple the amount needed in fact.
I pointed 1 to a bfg proxy and 1 to slush's mining proxy program but neither will exceed 7.2gh/s.
If it were network traffic issues adding the 2nd blade in "theory" should have dropped both?!
They are in the same network.
They both insist on changing proxy servers about every 40 work units requested.
You can not put a blank or the same ip for both servers or they will stop requesting work after 40 until they are rebooted.
I put a bfg proxy on a server and pointed them to 2 ip's on the server which works. but they do not exceed 7.2gh/s
I setup another proxy on another server and pointed the other blade at it. still will not exceed 7.2gh/s.
I changed one of the proxys to the slush miner and the other to bfg, still wont exceed 7.2gh/s
Neither are running hot, they have more than enough cooling on them.
in BFGMiner the first column says 10ish/7.2/7.0gh/s
What does the first column mean?

Same problem.

I had put the 6 BEs to the stratum on the RPi originally as addressing the cgminer running the BEs on another RPi directly to stratum.mining.eligius.st was getting difficulties in the /127. For some reason that is no long the case and the BEs are getting diffs of 15/1 or 163/1 and the like, much better. On the overloaded laptop stratum was showing for instance 1002milliseconds on accepted's for the Blade, way to slow moving the data, while the Blade is now showing [0ms] and: Total MHS: 11031 Received: 0000002592 Accepted: 0000002626 Per Minute: 150.91 Efficiency: 101.31% (oy) Up Time: 0d,00h,17m,24s soy So you r using the rpi's for your blade proxy's now? I am using 2 beefy servers for my proxy servers. Their activity is essentially nil, network utilization is .7%. Teamed nics etc etc. Both blades have creeped up to 7400 and 7300 the last 5 days from 7100ish. I could try using an RPI. both blades to 1 PI? |

You don't need much horsepower to run a proxy for blades or anything else. I've used a 1ghz netbook to proxy 100+gh without any issue. If your cpu cycles are locking up or the network has issues, then you will see lag, but that means you have other problems anyhow.

I am seeing 0 issues. cpu's and network are essentially nil. switches arent showing any issues. but as noted the blades change proxy server every single time they want new work. |

The blades are notorious for switching proxies for no good reason other than the fact they're on and working. They're finnicky, it's got to do with their network hardware/software. The only time I've seen them stay consistently on a proxy is if they're practically being chilled. My collection has currently been on the same proxy for over a day now, there's been 30*F air blowing across them the whole time. Once I take that away they start hopping. |

I tried two molex cables, and the first got melted. The second one I turned off before it got crazy again.
Any thoughts why molex cables get so hot?

What's the difference between the green and the blue blades (not the original, but the single board blades)?

You want 16ga wiring for each wire channel, or larger (14). Anything smaller could cause issues. Also if the molex isn't properly soldered to the board or connected to the wire or the other molex, it could cause heat/melting. |

It usually is written on the cable what gauge it is, but most of those splitters are 18ga, almost all molex wiring is unless it's the high-end stuff. I used 16ga speaker wire and made my own power connections. |

How come not many people have this problem then? IF this is common, posts regarding this should be all over. Maybe it should be included in the guide stating that most Molex is 18ga and you need 16 or under... |

For Molex, do I need to solder those doubled up cables, or just connect both into the screw? I didn't solder any cables, and maybe that's the problem? What about pci-e? |

Hello, I've been having problems with stability on my blade, is this PSU good enough for 1 blade?  I can mine for a few minutes on proxy for Slush's pool, then it craps out on me. Had someone help me in chat via teamviewer, tried to setup BFGminer to run as the proxy but it didn't work, blade reported "sick" a few times. I have this blade:  |

I've got a linksys wrt54g, not sure if that could be the issue. I'm thinking about using a crossover cable to my PC, not sure if that will bring more headaches. For the life of me I cannot get this going steady! |

Hi Guys,
Do I need to offer a bounty or post more pictures?
Please let me know what it takes for me to get to the bottom of this. I'm at the end of my rope here, feeling as though I have tried "everything".

I just figured it out. By walking away and going to the dog park my blade started working. No joke, the minute I walked out the door it started working. Ideally I'd like to find the root cause, but for at least for right now it's working.

Glad its working, if you continue to have issues I would go ahead and double up your power wires.
I run 4 yellow wires and 4 black, 2 wires to each terminal. Just to ensure it gets the power it needs, underpower will cause problems and burn out the equipment faster

Hmmm, I'll give that a try, no harm in running that many wires, right?? Right now I am using "C" only on the blade. You are saying I should add "D" as well?  |
