Thanks for the tips novak. I am using a 4.7 build right now but guess i'll have to track down a rpi. This has been a bit of a frustrating intro to mining.

Can anyone help me with the be controller? I have 4 units hooked to one the uart cable is in the right spot the switches are correct and when i go to the test page it shows all board are there and has the clean 000 but when i go to the stats page they do nothing. I've tried a few pools and checked the settings a few times to be sure. I have three controllers here and have tried each one. If i use cgminer they work but its spotty at best one second they are hashing away great then drop down and right back up till eventually between 10 minutes and 4 hours cgminer quits working and shuts down. Screws are tight on boards nothing missing. The temps are all well within reason. I start them in about 70 degree f. Each prisma has its own dps 2000 psu so plenty of power. I tried them all individualy with the same results. Ive tried everything i have read to look at but still being defeated. I have ten of these and can't even get one to stay hashing.
I haven't seen prismas do particularly well on BE controllers. If you're sure you are using a pool that works with BE controllers and that your network is fine, I'm honestly not certain.
As for cgminer crashing so frequently, that I have seen, it happens on windows when you use the customized cgminer 4.6.0 by ASICMiner. Try building cgminer 4.7.1 or newer on linux. I have seen them do much better running off a Raspberry Pi, I think CrazyGuy has an image for the RPi which works well.
If you're playing around with stuff I recommend using only a single board at a time, because the prisma can be very picky.

Well just got word, AM did not fulfill their promise of an entire prisma for compensation. They just sent raw boards to CrazyGuy (who has gone above and beyond to help everyone out).
So now I have nearly a month of downtime/reduced hashrate, more time to be spent cleaning up a heatsink with fire damage, bunch of money spent shipping to Hong Kong and from CrazyGuy to myelf and a broken promise for compensation. This is working out well.

I feel really lucky I guess I have one from the first Canary GB. I still have never had a single problem with mine running on a BBB hashing as advertised.
Sorry to all you guys who have had issues, honestly the only thing keeping me from getting more is all the horror stories I read here.

I have the same thing on the working unit I have. It does it with the BE controller but does not on the RPi Minera controller.
They are very sensitive to temp as well. When it gets below 40 degrees F in my mining room the boards will just stop hashing.
The String setup seems to be the culprit but I have not nailed it down yet. When on the BE controller it will just act like a board or two has run out of power. I have tried several PSUs and they does not change the behavior.

My unit keeps throwing up low hash warnings on ghash every few hours, and the controller resets after a while. Hash rate when its running is fine, all chips accounted for and chips temps never >90C or so externally. I've tried a known working controller and I've also tried @220 on the chips but no difference. Any ideas, I've not seen this type of behaviour before.

It you can't do this, then you need to find someone who can. Your lack of communication has pretty much destroyed AM's reputation in my opinion.
Well, I think you are right in so far as it did actually hurt AM's track record or reputation. But not nearly as much as other manufacturers or vendors suffered! The mere fact that they roll out this reimbursement plan show that they care about their customers and are in for the long run. They really do care about their honesty, it seems. I think it's a great sign.
SHILL!! ASICMiner is dead in my books, NEVER again. Phuck friedcat for designing this POS and then selling it to morons to man/dis. can you say ignore, just like Marto and Inaba deaf ears hear none of your future lies.
I think you are on the right track. But since this was not their original plan they went cheap on the components and the build. Trying to keep close to their original margin plan. But it cost them in shitty miners. They realize it now that they are building their own mining centers and have to deal with the same crap. See AMHash.

Similar issue with some of mine. Needs resetting every day. Often multiple times a day.
I have had the issue on Ghash and on BAN. Seems a little better on Ghash. Using a PC as a controller seems to work the best. BE controllers....not so good.

I am trying to unload my headache right now actually....
Canary told us to individually approach about initiating RMA. I'm still debating if chasing some tiny compensation is worth it. Frankly I don't even want to get this POS failed miner back.
Can I send it back and get a refund at the Group Buy purchase price of 1.47BTC? I'll pay shipping and will even send it back with a BE Controller, on me.

I presume the low hash numbers happen when the controller resets--do you have a USB UART to try the device with a rPi controller? December 02, 2014, 07:19:05 PM
Curious to see how this turns out. I covered return shipping directly to Hong Kong for the damaged board for which I was promised an entire prisma as compensation. That in itself was a gamble with paying for shipping, downtime for the fire, reduced hash rate while waiting for a replacement and having less time to mine at current diff. If it was just boards shipped to crazyguy I am going to have more down time trying to clean up the damaged heatsink so it can be reused and even if I get an entire prisma's worth of boards it's kinda hard to run them without a heatsink.

Agreed too little too late...
I just do not get this company...how they can not do simple tasks such as support and a forum presence. From what I can tell they only advertise these via a website (broken English to say the least) and here. I for one will not be buying anything from this company again after this experience (also had a bad controller on tube).

There's nothing to get. They are and always have been greedy bastards. Good luck getting your compensation, I feel more pain coming to these poor customers.
Well in both instances I sold off the miners ASAP to minimize my losses. I have nothing left to send for the RMA
I am glad that they're making an attempt. If I indeed do receive compensation for downtime and shipping, I won't be that disappointed. It remains to be seen whether or not selling it off and eating the loss right away would have been the right thing to do. I'm just relieved it isn't a total loss for me at this point.
