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?

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

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?

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.

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

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

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.

I made it work, i'm only getting 1 TH/S

Seems like 1 board is not working right ?
This is why my 1 TH/S ?
Any ideeas why it is not working ?

BTW: I only have 1 prisma it's supposed to show 8 boards ?

Four physical but opt logical boards.
How long did you let it run before checking the rate?

If we look at the test status all chips seem to be working fine only that board 08 and 24 won't start mining

I compile cgminer for raspberry pi

try both

https://github.com/ckolivas/cgminer
https://github.com/blockerupter/cgminer

can only get 1T speed

use their controller can get 1.4-1.5T speed

compile is quite easy

i just git clone https://github.com/ckolivas/cgminer.git

and cd cgminer

./autogen.sh
./configure --enable-blockerupter
sudo make

i try ckolivas's 4.7.1 , 4.7.0, and blockerupter's (which is 4.6.1), no luck, only 1T speed

It seems like one of your boards isn't hashing. Make sure all your boards are connected and the power supply cables are snapped in.

Yes, you are half right

i'm along with AM's guy testing it, confirmed it's a firmware related bug(can be fix with a cgminer update, and not affect every units), sometimes boards #0 #1 #2 #3 recognized as #1 #2 #3 #4, so only #1 #2 #3 is woking, lost 1/4 hashrate.

When it’s happens, cgminer will show tons of error like this: BET0: Unexpected value 00 received

AM's guy are fixing it, stay turned

Can anyone explain to me how to set-up the PRISMAS ?
How do I use that BE controller ?how many wires from controller has to be in 1 miner and in the controller ?
How do I chain connect them ?
Honestly I have no ideea, please help !

From Segmining: Since AM can not be bothered to reply of course

If you have multiple Prisma the "to Controller" goes to the next board etc..

You have to chain each of the Prisma's 4 boards together and then one wire to the controller. Each board must have a distinct address.

Crazyguy has an explanation of how to configure the switches https://bitcointalk.org/index.php?topic=795477.0

Also the BE controller might not be set up for your domain. The controller comes with a default IP address of 192.168.0.254 and the port to connect to the web interface is 8000. To connect to the web interface you will need to make sure the system you are using has an IP address in the same subnet as the controller (192.168.0.x) and once you connect you can change the default address of the controller in the settings dialogue.

Go to Dogie's setup guide: https://bitcointalksearch.org/topic/guide-dogies-comprehensive-asicminer-tube-setup-hd-769570 (I know it's for the tube but trust me...)
Scroll down to section 5a Configuration and follow the "Alternative Subnet Change" instructions to set up the controller for the proper domain.

Hope it helps

I'd like to know how loud it is.

Could someone post a video of a Prisma running ?

Agreed with the other post..sounds like a hair dryer. That fan is amazingly strong, and moves some serious air. You would want to run this somewhere isolated not in your house.

So it's meant to be run in datacenter, So much for incentivizing decentralisation. Sad

I like that I can heat my place and live nicely next to 6 antminer S3.

By the way, you should probably check the signature campaign thread and adjust your signature accordingly. Or you will not get paid at all.

I've had two running on my RPi for the past two and a half hours with no issues. One thing I did notice is that ASICMiner's build of cgminer does not handle the frequency parameter well. When passing "--bet-clk 23", I received a ton of "BET0: Unexpected value 00 received" errors. Starting with no parameters fixed the issue. I will test with the official cgminer branch later.

On the official CGminer 4.7.0 on both the RPi and on CubieTruck I got those errors on both options. As I said in an earlier post, pulling the USB controller and putting it back may have cleared it up.
