Can someone let me know what the Antminer S3 status showing -o-o-o-o -o-o-o-o -o-o-o-o -ooo-o-o means? Only one chain is showing this. The other is oooooooo oooooooo . Reason I ask is my Hash rate is 345 average. Should be higher.
that is a bad chain.
fixes may be:
1) lower freq setting 212.5 has helped
2) reboot via gui may help
3) make sure you have a good psu
If the above are not working, go back to this thread and read last two days posts.
Your problem will get solved.
My Guess is power supply. It's a cheap 520 watt from Best Buy. Will try a Corsair 750w later today.
How do I lower frequency? Currently at 218.75.
Highly recommending to immediately replace your power supply with a new good quality one like you said.
I will recommend you to buy an 800Watts power supply unit for you instead of the 750Watts PSU. Keep and eye on the single +12V rail.
Why you want to lower your mining power? Some do for some particular reason like placing in office and so.
Underclocking is simple, uncomment lower frequency lines(3) to select lower frequency.
Ok got the new power supply. Corsair 750M. Still getting the same -o-o-o-o -o-o-o-o -o-o-o-o -ooo-o-o for Chain 2. Any other tips? Can the Antminer be a bad one?
Post a screenshot of your S3 Miner Stats page.

It seems like a thermal paste issue. But before doing anything do a firmware update or factory reset and check.
If its not working, open up the cover of your Antminer S3. Look for any loose cables.
Then swap your cables which run from control board to each blades.
After 5 minutes check the miner stats page, if its working, you are lucky.
Else if, there are any changes from your previous image post the new image.
This time if its not working next step is to try a thermal paste replacement.
I expect this will solve your issue.
