5-10 minutes.
Should I wait longer?maybe it takes longer for all boards to start ?
it's weird that all boards start hashing except one ...

Well it doesn't count every hash so it's an approximation based on the number of hashes at a certain difficulty per unit of time.  It's probability based.  Wait half an hour or check your pool for rheir stats as it might update more quickly.

waited for more than 1 hour, still running at 1 TH/S and one board is still not running
so this is not the answer I was looking for ...

is it possible that it is not well powered by the PSU ? would it still be shown in the statistics tab if it wasn't powered ?

 Try connecting only that board to the controller.  Make sure you have power to the board that supplies the fan too!  You are using the 1300 watt EVGA?

My boards work 99% of the time, but when they do act up the answer is to reboot the Prisma.

My Prisma has never gotten more than 350GH/s. My opinion is that they are pieces of shit and should not be purchased. I can't even return this piece of shit because my reseller (Canary) basically blamed me and told me to fuck off even though it arrived with missing parts. Be warned if you buy one of these. You will waste more of your time then they're worth and will be disappointed.

I have power to all 4  boards, the fan is working.
Only one board is connected to the controller.
I use 2x 1000W PSUs

Thanks, was hesitating to purchase but now it is clear AM fucked up a lot

 Perhaps it was not clear that we are now trouble-shooting.  I was asking that you only power the board which is not hashing and only connect that board to the power supply.  That would be board 8/24 (switch setting 00011)  Disconnect the data cable interconnections to the other board and connect only the one long data cable from board 8/24 to the controller.  MAKE SURE to keep power on the board that powers the fan but only power - no data connection.

 Does that board work alone?

That doesn't sound like Canary.  You must have really pissed him off.

Did you make sure the boards were chained in incremental order?  (Example: 01:17,02:18,03:19,04:20,05:21...)  I understand it is crucial.

I agree. I had hoped for more from Canary as well, especially since I've bought dozens if not hundreds of miners from his buys in the past. I imagine he's getting lots of complaints and just didn't want to deal with it.

I've tried lots of dip switch settings. I get errors anytime more than 1 board is hooked up at a time and 1 of the boards is missing a capacitor and won't hash at all.

Wow. That sux.

Sorry about that, man.

You might want to mention this to Doggie, so he takes it into account on their ratings in his Manufacturer Trustworthiness guide.

Right now, ASICMiner's rated higher than Bitmain, which I find kind of odd... since I've never heard of them not delivering after taking people's money, or a delay beyond the stated pre-order date.

That guide is a joke  he gets paid from a few of them...also Avalon is 2nd highest rated lol. Yes Prisma is garbage and AM does not do any QC of the hardware. These are the absolute bottom of the line miners I have ever seen. I got screwed buying a tube also...avoiding anything AM directly makes in the future. It does seem that other companies using their chips do pretty good though..RM and BTCGarden etc.. If you have not bought one of these yet then save yourself the hassle..really late and tons of issues + no support or documentation.

Save yourself the hassle and just buy some AMHash.

while my boards all seem to work, I have not got the running time to go beyond 20 minutes and have not been given any reason why, even at 230 freq.  I bought one as an experiment and if the first worked I planned to buy more. The miner works, but can't figure out why running time is so low. Also there is no temp sensor reading on the block erupter nor does it show fan RPM. Can anyone make a suggestion? Should I go down to 220?

once i quit using the BE controller and went to the PI using minera from crazy all has been good if when making pool adjusments your log shows a ton of bet0 errors simply load the rockminer fork then back to CGam fork and all stays clear even thru failovers as i experienced with my pool going down to ddos today but do the fork loading trick as a simple reboot of minera does not always solve the bet0 errors

Shall we make our PMs public to see where I said something is your fault and where I told you to fuck off??

[wasikidding]

I will agree the setup is a bit of a pain in the ass especially the dip switches since the very nice diagram is accurate but reversed of the actual numbers on the boards hence 12345 is 54321 on the boards themselves and with the BE controller you have to reboot sometimes many times for all boards to come up hashing I believe it also causes a heating issue with the prisma as well as cutting your hash to 300gh/s with no notice over a few degree Celsius change as night turns to day etc

  I got the feeling the Prisma was a little rushed to market.  I don't understand how they can be so problematic - I mean this isn't their first miner... it's the 4th or 5th?!  

[Blazed]

To me it feels like they just send them out the door without testing... I think they look nice, and for the price do not expect them to be as nice as say Bitmain or others, but shipping bad boards and controllers is just pathetic. I really have no idea why they are like this
