Hi Mdude,
I like your easy to use and usefull app. I run your latest version (4.1) with 20 Ant S4s. I have small issue with rebooting. After device is rebooted from monitor I have only 2/3 of usuall hashrate, but when I use cgminer restart everything is ok.
Would it be possible to add 3 new features?
One restart device on Xcount, second restart device on low/high hashrate alerts and third restart device by the uptime hits.
Reboot is fine once restart does not work.
Thx, Ivan.

Hi all, I was upgrading FW on S3 miners a few days ago. By my mistake I upgraded one S1 miner with S3 firmware. When I recognized this, I flashed back FW for S1 miner. But now I can not set miner to work properly. In ASIS status I see 4 chain and the miner have only 2. Could you help me someone? Thx, Ivan.   |

Hi, yesterday I received an email about sending 3 new PSUs and information that other 7 will be shipped ASAP. I was really happy because I have had 3 miners without PSUs, but not for a long time. Nowadays I have 10 pcs S4 B1 and 10 pcs S4 B2 and a lot of S3+ miners. Today morning when I arrived to work I smelled burnt stink. Employees were scared, called me and ran around. WTF I said for myself. I hoped that the reason for all arround was not caused by miners but I was not right. I looked at the miners and two of them were down. Immediately I switched off all breakers dedicated for miners. And yes, one miner had PSU burned down. It was very easy to find which miner was bad  It was the fourth failed PSU. I checked all breakers and only one was switched off automatically. When the smell disappeared from the building (after 2 hours) I started with switching on the breakers one by one. After that I switched on PSUs on S4s. But another one from B1 and also one from B2 could not start. Also fans were stopped. I tried to reconnect the power but nothing helped. I have not understood what happened. All miners were running more than one week continuously. The PSUs do have really some problems. I hoped that PSUs in B2 were good, but....or today is only bad day for mining  Today status is 5 failed PSUs from 10 pcs from B1 and one failed PSU from 10 pcs from B2. Truly sorry about that, Sir. This is Tim Shao from Bitmaintech. You may have received an email from info@bitmaintech.com asking you to specify the PSU type. And i wonder if you can provide some photos to show us the burned PSU, i'm not asking you to risk running the miner again. But it does help if we can glean some actual info from the affected customer and submit them to the PSU supplier, and this will also help us improve the product quality to prevent this from happening again. Thank you for your understanding. I have the following questions: 1. "I looked at the miners and two of them were down. Immediately I switched off all breakers dedicated for miners. And yes, one miner had PSU burned down. It was very easy to find which miner was bad" Two were down, and one miner had PSU burned down? Which one was burned down? And what about the other one? Stop running? cannot power it up? 2. And you mentioned in the following posts that your B2 has barcode on it and you are sure it's not from the defective batch, can you provide me your order id for this miner, or would you please send me a photo of it? Thanks. Hi all, yes I have received the email. I am sure that the PSU is from batch 2 (have sticker and SN). Answers for Tim.Shao19: 1. My miners are connected in pairs to single breaker(2xS4 to 1xC20 breaker). When one PSU burnt down and breaker for this miner went down also another miner switched off. Is it clear? 2. Order is 00120141014004349482tuQeQyd106EE from 2014-10-14 00:43:50.0. PSU SN:188A410120045 PSU don't have visible changes outside and also inside. Hi there, we may have sent replacement PSUs to you, have u received any tracking no for the replacements? or you can provide me your email address or order id, then i will double check and keep you informed. And can you please provide any proof on your burned PSU if possible? (i know it may be difficult to tell the burned PSU from the appearance.) we need to glean some real info from customers and feedback with the PSU supplier rather than just claim that we got bad PSUs. Thanks. Hi Tim.Shao19, I sent you video with burned PSU last Friday. I really do not understand the purpose of that video you asked me for, as the burned PSU is not feasible to switch on, the fan is out of order. If there was a visible black burned component, I would have sent you a photo. But on this PSU are not visible changes. Today I have received information from customs office that I have two shipments. One with 3 PSUs and second with 7 PSUs. I was really happy, but... BITMAIN encloses invoice for 3*140=420USD and 7*140=980USD. The customs officer asked me for 280USD tax and 133USD duty. Great help Bitmain!!!Now I have 5 days to submit relevant documents that the shipments include only "warranty replacement parts" and the invoices with ZERO values! TIM, if you want to help me send me ASAP the invoices with zero vales and RMA documents that will be a prove for customs office. I refuse to pay any additional money your products related. I have spent a lot of time by the resolving problems with S4 miners. |

I hoped that PSUs in B2 were good, but....or today is only bad day for mining Today status is 5 failed PSUs from 10 pcs from B1 and one failed PSU from 10 pcs from B2. Can you confirm that the B2 miner that failed had a sticker on it? Early B2 units were shipped out with defective PSU also. You can see it by removing the top, no need to remove the PSU. (on my B2 anyways, maybe the sticker is elsewhere on others) Yes there is a sticker. On the other hand I have to say this B2 has a bit different inside in comparison with B1. If there is no barcode sticker on the PSU, then your PSU is still from the defective batch. For the one's that died and have a barcode sticker on the PSU, did you overclock them or they all running stock? Wondering if the extra overclocking is putting stress on the PSU overtime. I am sure that this is new one not from defective batch. I have had default setting with cgminer from Ckolivas. Maybe when sticker went down the PSU had stress or something else... |

@ manitu
One of the reps will be in contact with you to expedite the warranty process for the PSU.
We now have your OrderID and the details. Additional items we need from you were sent to your e-mail.
We are still here... we didn't go offline yet. You may see us come online, offline time to time. may stay online status but may have no one actually online.
Yes, now I am writing with Yoshi some emails. But I have written 4 emails before. First on 2014-10-02 because first PSU burned immediately after first start. |

Hi all, I am very disgusted with S4 quality. I ordered 10 psc, 6 working fine (not well) 1 miner have a lot of xx in Asic status (more than 60 xx) and 3 PSUs burnt. I am really curious how bitmain will compensate ours losses! I do not recommend S4 for buy. I enclose pics of burnt PSUs.    Have you powered the unit(s) with the burned psu on 220-240V or on an ~110V line? I have powered all on 220-240V. |

Hi Bitmain when I started the device everything seems to be okay. But after 4 minutes a lot of (x) appeared in ASIC status. When I do power cycle the situation is after 4 minutes the some. What should I do?  Wow, this device has very short live with default settings. After 3 hours of running many chips crash. Really bad quality of the products. I hope that bitmain will send me a new device instead of this one!!!  Definately something wrong there. Is your voltage set to 0725? Have you tried flashing the new firmware? Yes, voltage on 0,725V. I am sure that this device is broken. Firmware is original. |

Hi,
I need to set higher difficulty for my miners. How can I do that? Now I have diff from 1,4k-1,8k and need about 2k.
Thx.
What software are you using? Could be possible to do in the firmware or possibly on the workers page in Slush's Pool Settings I am using Antminer S4 devices. How it is possible to change diff on Slush Pool? I can not find this setting. |

Does anyone know what username and password could I use for SSH access to S4? The device is freezed but SSH is live.
Thx.
Try root/admin. That's for S2, I don't have S4 but maybe it's the same. Same as you need to get into the GUI. They are usually root, root for Bitmain products. Unless you changed the password. That's only true for S1 and S3, but S2 has root/admin for SSH and root/root for GUI. Yes, I just verified that on all three. Thx people, but device is absolutely down. I am so far from device that I will do hard reset tomorrow. I tried root/root, combination with bitmain and antminer, but all was wrong. I dont understand why bitmain changed root account. Maybe they want something to hide  |
