Overclocking:
I am getting 465GH at 237.5mhz with 0.6% hardware error (not exactly 478Gh) and 441GH at default 218.75mhz
Did anybody had a situation when at 225mhz S3 performed better than at 237.5, providing that miner is overclockable in principle?
well mine were so bad at 225 or 237. I quickly gave up. the 212.5 is now giving me 429 each with almost no errors .001% what is interesting is that same 429 on my gui and my m's ant monitor is about 433-435 at btcguild. Since btcguild pays me that seems like a good thing I made an interesting observation: at the default frequency, you get high GH numbers first, then numbers drift down to steady level. Paradoxically, when overclocked, numbers are awful at first, then slowly (over an hour) drift up. Perhaps, you did not wait long enough. I almost did as well, but noticed that my 5s hash was always much higher than average, then average was drifting up continuously. |

Try user name Wolframio.1 instead of Wolframio.worker1
Very dumb recommendations. Wolframio.worker1 is right. |

I want to report in on my findings, running a pair of S3.
One gets consistent 430GH over 1 day, 6 hours. Default clock speed
The other one gets consistent 410 GH over 1 day, 6 hours. Default clock speed
I've rebooted the slower one several times, and all chips show OK status. They are on independent power supplies. Only one miner per 700W power supply.
Only upside is temperature is consistently below 40.

did you try to ssh into it and change to 212.5 (as philipma did)? (comment on 218.75 with # and uncomment 212.5) |

So ... what is this random beeping all about from the S3's?
Every now and then I hear a beep, not sure if it's always from the same miner ... and neither of them ever switch over to a fall-back pool, so connectivity seems OK.
It's just a single beep, so contact with the pool/internet doesn't seem to have been lost.

I don't think anyone has nailed it down yet. There have been some theories ranging from expired DHCP leases to HW errors causing it, but nothing concrete. At this point, I just accept it as them telling me they're still working. Now, if Bitmain releases an update that fixes it, I'll be constantly wondering if they're still working properly  |

out of four that I have there are three "beepers" and one "silent type" that beeps only when restarted. Among beepers, two beep only once in a while (like once or twice a day) and the last one beeps once in a hour. |

Lol, Bitmain made a bitcoin miner clock strangely, but the beep does not bother me one bit since it is in one of the bedrooms upstairs. |

i am wondering how much power the S3 will use on the server style power supplies anyone check the power usage on these? the cheap ones. i just wanna know it worth paying more for a gold or plat.

^depends. If you can do server gear for <1/2 the cost of a gold supply its worth it IMO. But if you can get a good deal on an ATX supply it might be a better long-term investment |

I have a question.
Why did Bitmain put 4 power connectors on these S3's if you dont need them ?
Usually they try to save every nickle they can, why engineer something in that's not needed. ?

here is my guide to reducing the sound of the beep https://bitcointalk.org/index.php?topic=701338.01) reboot = beep - yes 2) pool switch via gui = beep -yes 3) auto pool switch due to a pool crash = beep - yes 4) hardware error = beep - ? 5) other reasons = unknown at: bobsav2121 if you over clock you need 4 pcie connectors. the reason is a 6 pin pcie wire is not rated to carry 200 watts many s-1's melted pcie wires when over clocked |

Very dumb recommendations. Wolframio.worker1 is right. "worker1" for bitcoin.cz - sure. And don´t wonder if we start to laugh. We are just a happy crowd here  #facepalm |

Well I guess since these cant overclock ( yet ) it's a mute point,
Thanks
Has anyone identified the sub par part that they used ?

People who say anything about not meeting ROI are ignorant. How can you comment on ROI when you have no idea what the cost of bitcoin will be next week, next month, etc.
mpark the proper way to factor ROI on any miner actually doesn't involve the conversion price of BTC to some other random currency. If you pay X BTC for a miner and in it's life it generates >X (plus costs) then the miner profited. If you buy a miner for 1 BTC when it's at say $500 and it makes .5 BTC but the coin doubles to $1k have you broken even? If you believe you have you are allowing yourself to be blinded. ... is there anything that ROI in BTC?... dont see much of a future for home mining... just for manufacturers. |

I'm sure someone will start a cottage industry soon to modify these things and get them back on track. After all everybody that bought them was planning on starting their overclock from 478 |
