Just got the S2. Is this the symptom of a bad power supply?
If I have more than 5 boards running, the miner would start and when the screen goes to Antminer and starts hashing, it would last for only a few seconds and turn off. If I have only 5 boards in there, it would be hashing fine, and the pool stats show that it's hashing around 500.
Get a good Gold or Platinum 1200w or greater PSU and swap out that underpowered garbage Enermax.
No problem with my Enermax, all 10 blades work very well at about 980 Gh/s on pool cex.io.

http://img4.hostingpics.net/pics/650716cex2.jpgCould you and all reasonable people please stop using cex.io/ghash.io
or all your (and mine) bitcoins will turn into pumpkins-use Eligius or anything else for crying out loud
I don't understand why you tell me not use cex.io/ghash.io ?
Can you explain me what is the problem with cex.io/ghash.io please ?
Best regards
Yes, please get off GHash.io immediately.
Have you heard of a "51% attack". Well GHash reached 48% today, so do your part for the Bitcoin network and mine on Eligius, BTCGuild, or Slush's pool instead.
Ok, i understand, i get off GHash.io immediately, going to eligius.st
Links to understand :- Bitcoin Hashrate Distribution :
https://blockchain.info/fr/pools?timespan=24hrs- Bitcoin 51% attack :
http://learncryptography.com/51-attack/Finaly go back to ghash.io
On eligius.st, i have to wait 13 blocks found to be paid, so about 2 days.
On BTC guild, i have to pay fee.
On ghash.io, i'm instantly paid with no fee.
This explain why everybody mine on ghash.io !
Don't be a "me too" follower on the biggest pool with lowest variance with no fees, but poses the greatest threat to all of us in Bitcoin.
