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.
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.
[We did not participate in group buys, this is our own experience]
Hi, so, this has been a total nightmare. But, I found this information posted by CrazyGuy to be reliable
https://bitcointalk.org/index.php?topic=795477.0 and he points out flaws with the dip switches and notes on the "virtual boards".
Also, 3/16 of the prismas I've received had caps rattling around the boxes. I have 5 of our own I've yet to open, 4 from a customer I've yet to inspect. These all came straight from AM. Also the Tube we received, I'm guessing as compensation, had components that had fallen off in the shipment. This has been a total disaster.
