This thread is for support related discussions of the BITMAIN Antminer S2 hashing device
How to overclock your miner to 400MHz / 205GH/s. My suggestion is to clock them at 375. 400 is a bit too harsh on the voltage regulator.
All clock speeds including 375MHz work on both revision of boards.
The miner will draw 500 - 525Watts at the wall (110V mains) after this setting
....
Please donate if it works for you: 1FrW5ka9CRVWdL9EM4Jut9eHWU1a1biyy5
Hi, Is there a special Btmain Antminer U1 support thread for Wndows users? Thanks The operating system on your pc is irrelevant to the antminer as you access it via a browser or ssh |

I haven't managed to control the fan yet, but for those who don't care about noise and want better cooling you can just remove the blue wire from the fan connector (or cut it, if you're lazy). Just use a small precision flat blade screwdriver and push in the little locking tab at the back of the 4 pin fan connector. In the absence of a PWM signal the fan just spins up to full speed, which the Antminer is reporting as 3900RPM. Doing that dropped my temps from 47 to 35 at 400MHz.
Thanks for this! Lowered my temps 10 degrees with just this. |

Anyone think it is ok to run the whole antminer off one PCI-E cable? I ordered a power supply I thought was coming with two PCI-E cables, but it just has 1 with two PCI-E connectors on it. Don't want to melt the cable...
Anyone suggest a decent cheap 80 plus Bronze or better PSU with two PCI-E cables?

1 PCI-E cable is just fine. I have 4 miners running for over a month each on a single pci-e rail. Alternatively you can power each blade with its own PSU. It draws even less W that way and you can go pretty cheap. |

It draws even less W that way and you can go pretty cheap. Bad advice if the wires are anything less than 8 gauge. At default clock you are pulling about 30 amps minimum over the PCI-e cable. If he has a cheap-ass cable and connectors, could be disaster. |

Thx for advice all. Think I found a good Seasonic 550W Gold with two PCI-E cables, will try ordering one of those. It's going to run around $90 though, any good cheaper options for an overclocked S1?

in my tests, 0780 & 4f81 yielded the same result - so I think they are both very close, if not 400mhz
I can confirm that my overnight test seems to be a success... averaging 197GH @ .59% HW ... which is higher than the 375mhz setting, but lower than 400mhz
I dont know what the exact equation is for figuring out hashrate based on clock but the numbers match up with 512*mhz = mh/s
Based on that equation, 5e82 seems to clock in right around 384mhz
Also, if someone wants to experiment w/ the xx83 ranges ... I imagine the values will start in the 6x83...
Don't if this could help http://www.mathsisfun.com/binary-decimal-hexadecimal-converter.html |

MrTeal please invent a "universal" server PSU interface doohickey, and take my money If there was a universal server PSU connector, I would. I like the idea of a ~500W PSUs since then I can use short wires and make one PSU per unit, and I can buy the proper mating connectors for the one I linked at Digikey for $5. http://www.digikey.com/product-detail/en/51741-10002406CCLF/609-3637-ND/1490627Toss in less than $1 in wire, and you're good to go. |

Does anyone know how to get the getwork protocol working in the antminer S1? Want to solomine some altcoins but when i try it with RPC connection directly @ my wallet it only gives rejected blocks and when it has to accept 1 it goes standby . With my knc miners i didn't had any problems at all. I know this is an getwork issue... anyone a idea about this? Thanks! |

Personally, I would not damage the modular plugs that came with your power supply. You may want to reuse your power supply when the ASICS are just paperweights in a few months. Go to your local computer store or electronics shop and get an extender cable that can fit into your CPU plug. Butcher that extender cable to extract the 12 v wires. Cheers! |

Hello Fellow Miners, Yesterday I received my new AntMiner S1 v.1.4 (2013/12/1) hooked it up to a new Corsair 1050watt PSU and powered it up, pointed my browser to the IP listed on the miner, set the settings and boom I'm mining!   However, when I SSH into it, to OC to 375MHz, I get "alias: -1 not found". I log into the miner via SSH with my username and password yet I not able to bring up "cd /etc/config" to edit or make changes to 'asic-freq'. This is the new Ver. 1.4, any help will be appreciated. Thanks, jesse11 |

'vi /etc/config/asic-freq'
pressing 'I' enters editing mode
pressing 'ESC' exits editing
':wq!' writes the file and exits back to the command line
reboot
