49 degrees C a little too close for comfort especially if overclocking. Might want to keep blades at or around 40-44 C for optimal runtime, as well as, keeping the blades and/or PSU from shutting down. Too close to what limit? cgminer on an Ant is set to shut off at 70c. Burning out your unit. Check through the antminer troubleshooting and setup threads. 40-44 is optimal temperature. 70 is bye bye investment. I think you need to stop believing what you read on these threads and do the research. The datasheet for the product is here https://github.com/AntMiner/AntGen1/blob/master/datasheet/BM1380_Datasheet.pdf and states that the BM1380 chip has a maximum operating temperature of 125c. The temperature monitoring chip is in the middle of each board and to allow for the temperature difference between hash and temperature monitoring chip the /etc/config/cgminer has been set at option target '60' option overheat '70' |

I am around 0,03% HW then?
Edit: It was a stupid question indeed. Thanks for the help!
0.03% is a good error rate for an ASIC, other vendors would love to get it that low and at that wattage. You temps are low, your fans at half speed, your chips are good, sit back and relax! PS: It wasn't a stupid question, just a lazy one  |

One of my antminers is overclocked to 400 Mhz and it is hashing stable around 200 Gh/s / 41-43C°. Btcguild is showing average of 200 Gh/s as well. The only thing bothering me is HW errors. How can I check what % HW do I have. Thanks!  It has been said many times in these threads, search is a wonderful thing  HW / (HW + DiffA + DiffR + DiffS) = % |

You can't owe Bitcoins because you can't owe which is not owned ... Then by your own statement Bitmain owes you nothing. Not really... They are selling a product for Bitcoin and their own contract states they must deliver Yes really... You owe people BTC that you will not pay back on the assumption that you can't owe which is not owned Bitmain owes you BTC that by the same assumption they do not have to pay you as they cannot owe which is not owned Nice Work Captain Obvious Destroyed your argument though  |

I'm EXTREMELY DISAPPOINTED that out of the 8 I ordered most of them were used! Two of them are already past their warranty date and don't even have PCIe plugs on them (past generation out of warranty hardware). One of those was DOA, the other one's fan is noticeably louder than the rest. Has anyone that ordered from Bitmain received used equipment? Sushi has some serious explaining to do!
Can advise how to check warranty date? Thanks! The warranty date is the date the order was sent not the date of boards manufacture. |

Could someone PLEASE help, again:
I have an issue with a unit where it wasn't connecting to Wifi At all I have my others setup correctly so it was no issue beforehand. But for whatever reason this specific unit wouldnt detect any wifi so I decided to press the reset button on the controller board. Now I cannot detect it at all. I've tried to do the reset procedure a couple times and its still the same result. I have it connected to a switch that is connected to the router. All the other units are fine, its just this one unit giving me trouble...any ideas or suggestions?
Reset button is what caused this to happen, I cannot connect to it at all even if its directly plugged into my computer. I do see activity on the controler with it being plugged into a switch that is plugged into the router. This device had worked okay before. Someone on IRC said at this point the only thing I could probably do is JTAG but bitmain says "not possible for the avg user" If that is what I need to do, fine, lets do it, but could someone walk me through that?
I've tried to:
Reset miner as FAQ states.
Do the full 30-30-30 power cycle with the reset button pressed down
SSH into the miner with the default .99 IP
SSH into the miner while connected via ethernet to the default .99 IP
Unplug the device. Download a decent IP scanner, famatech's IP Scan will do. Display your IP address details, and write them down. 192.168.x.x mask 255.255.x.x, Default Gateway, DNS. For the purpose I will assume your PC's IP is 192.168.1.11 but just replace it with yours Set your PC's IP address to be 192.168.1.11 Set your PC's IP Subnet Mask or NetMask to 255.255.254.0 Run the IP scanner and take note of all addresses Plug in the Ant to the switch and wait for the lights on the ethernet port to come on. Run the IP scanner and find the new address that was not there before. Connect to the new address and set the WAN IP address to one that has the same first three set of digits as the IP address your PC, for example 192.168.1.x where digits in bold are the same and x is a number that is not on the list of address in the IP scanner. Apply the changes on the Ant miner, the display will never, ever get past the point where the wait circle keeps on spinning, just leave it as it is. Set your PC's IP details back to the original that you wrote down. Power the Ant off, wait 5 seconds, then power the ant back on. Wait until the lights on the ethernet port to come on. Now connect to the ant using the browser on the IP address that you set on the ant. |

Mt Gox, is a rehash on the old market maker confidence trick that happens all the time.
Step 1: Offer to buy something at a higher than average price, pay out quickly, build confidence
Step 2: Slow down the payment for the thing being brought, sell some of the things to pay sellers and pay off original stake
Step 3: Claim xyz has happened, gone to hospital, cat's died, tech failure, etc and that you cannot payback now but will when the problem is fixed, out of hospital, etc allowing time for even more funds to flow in and for funds to be sent elsewhere.
Step 4: Bring new staff on board to run the outfit.
Step 5: Offer the things for sale at a lower price than market but delay sending things claiming again a re-occurrence of 'xyz', plus new staff are untrained, illness returned, new cat has kill the dog, etc allowing time for even more funds to flow in and for funds to be sent elsewhere.
Step 6: Put distance between yourself, the sellers, buyers, authorities and let new staff deal with the problems.[/li][/list]
The same trick has been played many, many times and until Step 6 occurs, the confidence trickster can just claim incompetence, lack of business knowledge, pet shop owner, etc and get away with it.

... Would love to get it down under 40C.
Why, what do you base your reason on? |

OK, I just checked and it is not selected.
Thanks for the reply.

Something you are running is trying to change the clocks, you have going to have to go through a process of elimination to get to the solution or use a different toolset/BIOS combination. I had a similar situation with Gigabyte cards and the catalyst driver set that I could only cure by using MSI Afterburner and getting it to force a constant voltage. In the end I swapped the BIOS for one with a set voltage and removed the problem that way. |

I have several units that don't have working fans. Which is not actually a problem with the fans but with the units. I just wired the fan's directly to the psu. Neither of the fan connectors seem to work on the problem units. Anyone know the cause of this?
Let me know if you find an answer to this, I've got one ant that's just blowing its fan at max RPM, the controller doesn't seem interested in controlling the speed like my other ones. Interestingly I noticed the fan looks like a different model compared to my other ones that are working. So I'm not sure if it's the fan or if it's the controller. The later Ant's do not turn the fans until they have been hashing for a while, and the earlier fans will sit at 400 - 500 rpm lower. If you think you have a problem and multiple Ant's the just swap the fan and see if the problem follows. |

Make sure you have disabled AMD Graphics OverDrive in the Performance Tab of the Catalyst Control Centre

Where is the reset button. I am having the same problem being unable to connect to the miner ip
On the controller board. |

Love my ants but the noise is going to piss my gf off, can anyone recommend any slightly quieter fans? Will any 4 pin silent 12cm fan work? Maybe if I put one on each end?
Get a quieter GF  |

PIC32MX250.hex and antMiner_openwrt20140207.bin . Is it enough flashing antMiner_openwrt20140207.bin ? What is the purpose of PIC32MX250.hex and how/when do you flash it?
Does the cgminer miner included finally support bfgminer proxying ?
Just flash the antMiner_openwrt20140207.bin The PIX32 is for the microcontroller. |

So if the new firmware targets a lower temp, does it make the fans run louder?
The firmware target the same temperature option target '60' option overheat '70' It is the hardware fan controller that is different |

I did 2 days ago, no issues so far.
Aside from the cgminer version change, any other improvements or changes? Also, when you update the firmware does it lose any of your settings? You get the choice to keep your settings or overwrite them. |
