To answer my own question in case anyone else is wondering, I just got my tracking #.

Well, I'd rather have a buggy unit ASAP as opposed to having them test them and drive the difficulty up in the process before I get my miners. To be honest when it works it works very well. Happy to have it so quickly after ordering.
Well, I'm happy you're happy  Myself, for that price, I'd prefer not to be treated like a guinea pig beta tester on a miner that might work on certain pools if I'm lucky while hoping my hash power is going where it's supposed to go......  Hindsight and all that jazz. Here's hoping by the time/if you decide to buy one you'll get a bug free miner. |

Can anyone comment on whether they received a UPS tracking number once their order was marked as "Shipped" or not?

3.12.0
As I feared. Your S4's are working fine - it's just that someone is stealing your hash.......  Bitmain fail. Can this be prevented in any way in the mean time? Use of a proxy, or something? Why doesn't this happen with all pools? |

Hmmmm, could someone tell me what version of cgminer these come with? Also, if someone wouldn't mind telling me how they fair on p2pool - that would be cool. Even better, point one at my node for 10 mins using a wallet addy as your username: stratum+tcp://iyftech.zapto.org:9332 .....just so I can see how they perform with p2pool & weather I should get one or not.... Thanks in advance Someone? Maybe p2pool is the only pool they work with...... 3.12.0 |

I did a buy on the S4's and their hashrate locally is 2th/s or greater (awesome!) however, when connected to BTCGuild NONE of them show anywhere close to 2 Th/s. They show more like 200 Gh/s. I have 2 that are over 1 Th/s, but the rest between 0 - 278 GH/s. WTF Bitmain?  BTCGuild and Ghash are the only 2 pools which I've tested that actually work. You may need to power down the miner (not a reboot in the miner's web settings) to get it hashing properly. Any changes to the miner's settings without a hard reboot can cause the issue you're experiencing. Very frustrating. |

Ah, that makes sense. Thanks. |

Ok, got it going again after 2 more hard resets. Hope I don't have a bad unit and that this isn't a sign of things to come. This thing needs a firmware update ASAP. Yes? |

Great, my S4 just woke me up with it's annoyingly loud beeping. It's dead! I'm able to log into it just fine, but nothing shows up under status. Tried 3 software reboots and 2 power downs. Nothing! Just hard reset the miner following their instructions in the S4's manual, and now the machine isn't getting an IP address. Display is showing IP as 127.0.0.1. Anyone know what the button above the reset button does? Edit: Nothing. It's just a hole with no button. S4 was running at stock speed and voltage. Time to see if Antminer provides good support or not, I guess. Of course they're on holiday.  |

Looks like my scrap metal has shipped. Did you guys receive tracking numbers for your KNC hardware?
Nope. #201xx, paid March 21 I meant people that have received hardware, ie status changed to shipped. Can't find a tracking number anywhere. |

Only pools working properly for me are Btcguild and Ghash.io. Even then, Ghash.io sometimes needs the S4 to be powered down and restarted to work properly. Use Btcguild until firmware fixes these issues.

Yes, they were captured within 2 minutes of each other. There is a backup pool set, but it hasn't received and shares at all if that's what you're wondering.
May I ask what the formula for calculating hashrate from the diff 1 shares is?

Just took delivery of my S4. Cost an extra $220 at the door for customs in Canada.
Nice looking box, kill-a-watt is reading 1308w on 240v.
Going to have to reverse the fans as the airflow won't work for my setup.
Why wouldn't you just turn the box round I could, but then I wouldn't get to see the screen.  |

Can we get actual proper specs on the included PSU?
Is this close?
1400w or 116.66A continuous 12v output? Assuming 88% efficiency, that should read as about 1591w at the wall if the miner is consuming 1400w DC correct? Who manufactures the PSU? I get a little nervous when I read "custom PSU".
It's 1400w at the wall. No, I'm pretty sure the PSU can output 1400W DC. PSUs are never rated with what they draw at the wall. Its a 1400W DC PSU, ie 116A @ 12V. Any idea who manufactured the PSU? |

There's an issue with Antminer S4 and Eligius, Eligius isn't reporting the hashrate properly:   Pretty sure the issue is with the ASIC, but I figured I'd post this anyways. |

I don't get it, Eligius just won't report the hashrate properly.  |

Testing 225MHz @ 0.725v right now. Power draw = 1525w
What is the hashrate? It's advertised as 1380w at the wall at 2000GH/s. * Hash Rate: 2,000GH/s guaranteed
* Power Efficiency: 0.69Watt/GH/s at the wall
200MHz/0.0725v(stock): 2010GH/s @ 1305w = 0.65Watt/GH/s 225MHz/0.0725v: 2243GH/s @ 1505w = 0.67Watt/GH/s That's using Eligius. Nicehash doesn't work for shit, was only getting about 1650GH while overclocked. I'll post more as I test, likely tomorrow. Edit: Seems like Eligius' stats are messed up? Hashrate average over the last 256 seconds is only 48GH/s Edit 2: I'm trying to find a pool that reports hashrate properly, as Eligius isn't. For some reason the miner won't connect to BTCGuild... Pool is showing up as dead. eligius is fine for me right now. thats a nice 10% overclock, any signs its too much for the psu? 1505W at the wall with ~89% efficiency near peak power = 1350W from the PSU Really? I'll try switching back to Eligius then. PSU seems to be handling it just fine. I cranked the voltage up a bit a while ago to see how it affected consumption, and drew as much as 1640w (over 1400w DC) at the wall before backing down. I don't feel like being the guinea pig to find out if this thing has OCP or not. Running at 225MHz:  |
