still after 25 hours in status start showing a few x oooooxoooo example...
Can somebody explain why , still after 24-25 hours and oboth same :-(
Alarm bells should be ringing if you dont see hashing after 5 minutes never mind 25 hours. There must be something wrong with your setup.
You think bad oc ? Or low psu ?
low psu = bad oc
what psu do you have?
[edit] establish whether it's harware or psu - run 1 miner not overclocked on 1 psu - you should see 180G
500 watt is probably too low - I think you need at least a 750 - amazon sell a corsair 750 for 62-70 UKP. You'd need one of these for each of your S1s.
What rate do you get with just one un-overclocked S1 connected to the 500w psu?
