Great job again. Now is this with your fork or the main fork of Minera and cgminer? First 2.5 hrs mining mining on the pi and 2 prismas. No reboots and running solid. Total hashrate display in minera is inaccurate. Device hash rate below is accurate and matches what I'm seeing poolside. I'll have to look at the source this weekend and see what's going on. One thing I did notice is that ASICMiner's build of cgminer does not handle the frequency parameter . When passing "--bet-clk 23", I received a ton of errors: "BET0: Unexpected value 00 received". Starting with no parameters fixed the issue  |

Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

I think I may have some problem hash boards with that last set  Hashing fine for a few hours a little under but acceptable for sure then hashrate really dropped. Isolated them one by one tried altering the way they are chained, two controllers, and two power sources. One of the boards the row of large transistors gets so hot they will burn you just powered on without the controller, so I have it unplugged, but it will descend into ugliness anyhow like this picture:  gunna unplug it and fight it tomorrow |

@CrazyGuy The above post is exactly what I've been dealing with. I think it's the BEController as oppose to defective boards. Look at the previous image his first prisma in the chain has completely reset and look at the HWerror rates of the boards that are alive. Also he is missing all together board 12 which sometimes happens as well when boards start resetting.

Check the board for loose or missing screws. Also look for shorts. A big issue with the cubes was excessive Flux and sometimes solder flakes getting stuck to the board and shorting out compenents. I haven't seen this with the prisma/tube's yet, but worth giving a lookover.

Update on the RPi. Miner uptime is now 8 hours. No issues or restarts.

NVM had dip switches backwards thanks up and running cant wait for adapter to try pi with wifi |

Wow I should know better. Every screw was loose (literally all of of them). Been hashing now for 2 hours no spikes in HWe's and no board resets. Wish I would have thought of that yesterday. Will keep you updated. Damn... EDIT: Well that was a premature celebration HWe just spiked and boards started resetting. The common denominator here is the controller there is no way this many boards are defective. |

All usb adapters have been shipped!
RPI is still running strong for my 2 units. I forced a reboot to ensure the units starts mining automatically and all is well. With that said, I have no current reservations about running the Prisma on a Raspberry Pi.

Update: I think I am making progress. I took the first prisma and took off a problem hash board and inspected: some spots of flux stuck in the holes where the BE200 chips are mounted to the PCB, cleaned those up best I could and screwed it back down. Fired up the hash boards one by one and I currently have it without any of the PwrDn counts on the controller. Prisma #1 is now hashing great  On prisma #2 blade #4 it is getting PwrDn counts and not hashing, I will attempt the same procedure above here for it. On prisma #3 blade #4 has not hashed yet and seems shorted somewhere I have not removed and inspected it yet. |

So I've been scouring the forums, please forgive me if I missed the obvious answer.
This is the first bit of AM gear I've had recently, and I'm curious about the number of dupes I'm seeing on ghash.io. It averages out to about 6%, which seems a little high to me. I'm running a Block Erupter controller, although I should have the rPi running next week.
The machines are running 99.5% efficiency on the back end, and I've seen no PwrDns and the HWe is 0.1. Anyone else seeing similar results? I'm 30 minutes from the DC on the weekends, so I'm hesitant to reboot.
Let me know what you guys think!
Cheers.

Which version of cgminer are you using? Is it the official AM one or just the latest cgminer version? How was the set-up? |

I'm using the BE controller until my USB adapter arrives. It's "BE200 Jet Stratum Miner V 5.47" |

anyone else have issue where the prisma comes up great but within in hour it just keeps losing hash down to like 700gh/s? I am using the BE controller atm until adapters arrive

That may be a PSU issue. You might try chaining just two boards up and seeing if it acts saner, then try the other two boards and see if you can determine a bad board. If everything runs full speed with two boards, try three. What type of PSU do you have? |

BTW the corsair wires get warm I saw people saying 2 of these to run the prisma i would say better to have the evga 1300 less watts but wires are better |
