I would have to agree with you. I have 16 S3's and 1 S4 at the moment. 4 more S4's are on the way.
I did notice something that caught my eye when you said, "no X's"
I know this is an S4 forum, but one of my S3's has a dash at the end of the zeros. what does that mean? "00000000-0000000-"
Not sure actually. X non-responsive? - dead. Just a guess. But a hard reset usually does the trick. Okay I'll reboot and see what happens first before doing a reset. EDIT: REBOOTED AND IT"S STILL THERE May have to do a hard reset like you said. |

My S4 ran perfectly for a few days but is now getting x's and significantly reduced throughput. e.g. 3 x's is costing me about 10% hashrate. This is happening at stock speed, at both .720 and .725 volts, with the same chips dying. Takes a few hours by the way for the chips to go offline. http://puu.sh/d0D9J/338e2c960e.pngAny suggestions? I'd like to see 2TH again. Cassey LOL I Just noticed I quoted YOU, Cassey LOL |

I'd like to see 2TH again. Cassey You might have to do this and settle for 1.8 Th/s: If you read a couple of posts before this one I quoted, you will see the reason why. Others perfecly normal only J7 connected hash board is unconfigurable, if you want to proof of that disconnect this board power cord and you will see chain 1 is gone and look at your power wattage. or try to configure voltage and repower again. i have 2 S4 and all of them have same problem.
and i found best configuration and best efficiency = 187.5 Mhz at 0.685 Volt (you can add this value like that = 0685)
this is the best...
Wow! So, you recommend all of us with batch 2 to switch to 187.5 Mhz at 0.685 Volt? Will doing this lower my hash rate? If so, by how much will it lower the hash rate?  of course that is lower than 2Thash but also eat lower energy  and also lower Temperature and lower noise like 1800Ghash 1060W i think that voltage adjust problem is master reason of psu's blowing because developers unexpected situation like that. they put a 12V 120A top limit psu and they expect 1200w power usage but not, some of hash boards still working warning limits... NOTE: He said 1800Ghash @ 1060 watts. I think he intended to say, "12A and 120V" instead of "12V and 120A" but I could be wrong. |

are the new batches of s4's still having issues? I was hoping to order with the coupons they issued for $400 off but now I am having second thoughts and thinking of going with the other guy starts with an S idk gotta look them up.
I've ordered 1 already and got it on the Nov. 14th. It's been doing great for me. I have 4 more on the way. I've mounted 3 PDU's today on the wall. About to install a cutoff switch and run three 240V/30A circuits to it and then into the closet once the S4's arrive. I will keep mining off my 120V/20A until then.  Cat6 cables waiting to use. Mounted PDU's with a gap from the wall to allow power cords to go behind them. A blue cord is already behind one for show. I did accidentally unplug it while installing the PDU's approximately 6.5 hours ago. However, what concerns me is best share is ZERO EDIT: Switched from Slush to Eligius and immediately I have shares.  EDIT: I went back to Slush and still best share is ZERO. I get paid for the TH/s at Slush. However, the best share is always ZERO at Slush. I may switch to Eligius as soon as other S4's arrive.  |

My miner perfect work at a frequency of 268.75 - 275, and outputs the 2500-2700 ghesh
WTF? that's pretty good. Did you have to change the voltage too? Does yours run stable with no X's for a long time? dont believe some like this, without powerful psu thats meanless.. There is absolutely no way to push the mhz to 275 on the supplied PSU. Hell, I can't even get it to run 250mhz and I'm on 220-240v (lower amp draw) in Singapore. The best I could get it to run stable is 231.25mhz at 0725v. But watch the tempreture. Mine goes up to 63-65C which I believe is still ok (there must be a reason why the cut off is at 80c). As long as you do not switch pools, or restart (not hard reset), the X's don't appear. I would have to agree with you. I have 16 S3's and 1 S4 at the moment. 4 more S4's are on the way. I did notice something that caught my eye when you said, "no X's" I know this is an S4 forum, but one of my S3's has a dash at the end of the zeros. what does that mean? "00000000-0000000-" |

I don't mind but others might. If you feel you should create a New Topic, please post the link to that topic here for me please.
Thank you.
Well, to avoid causing any stress, I posted it here: http://asic.usertalk.info/index.php?topic=159.0 (that is a lightly used forum I maintain) Cassey Thank you! Sorry late thanking you... I'll have a look at topic tomorrow. Still involved with trading coin... |

Static or dynamic (DHCP) shouldn't matter - networking routing, firewalls, etc. will.
If you can connect to the IP address displayed on the unit while on the same subnet, BitMain has delivered. If the unit is not displaying an IP Address, then you either don't have dhcp running on that subnet, or the unit does not have a valid network connection (bad cable perhaps?), or the unit is broke - in decreasing order of probability.

Thank you for your contribution to this discussion, Cassey. Like I said, I'm not a specialist. I used YouTube videos to help me learn what I wanted to do with mine. David Sorry if I came across too strong there. Networking can be complex - like learning to swim. Tough to learn the basics, then it comes naturally. If the groups wants, I can post the basics - should only be a mildly long post... I don't mind but others might. If you feel you should create a New Topic, please post the link to that topic here for me please. Thank you. |

I could be wrong on this: I would believe your network the S4 is connected to would need to be set up for DHCP and you know the address assigned to it [whether it was assigned automatically or manually as in my case] in order to connect to your S4.
Bitmaintech is not responsible for what you do with your network set up and whether you want to connect remotely or not. They are only responsible for the unit. If the unit had problems connecting to it remotely, THEN I could see bitmaintech coming into play.
However, I honestly believe you need to set up your S4 to connect to a DHCP network NOT static in order to connect to it remotely within that network.
I'm not a network specialist. I'm just telling you how I have mine setup with my Airport Extreme Base Station from Apple.
The DHCP server issues the static IP to the S4. Learn something almost everyday on here. Thank you! Nothing wrong with 60C, I'm almost permanently at 55-60C due to a 35-40C ambient.
But it is in a shopping centre with air-con and an ambient temp of 24C, so going by your temps it being 46C (coolest board) to 51C (hottest board) seems normal. I don't think the 61C is normal at that ambient temp of 24C. It was only 1 board that was reaching high temps, not all 4. The other 3 boards were still running at around the temp they normally are. I monitor this miner several times a day so I do know what my average is for my miner. It is currently stable with the hottest board at 51C now and hashing at 2TH. This is a software problem. Sometimes i have it too, after power failure.
You can stop function - Stop running when temprerature is over 80℃ - only thing you need restart miner with PSU manually. Hope this can be addressed with some kind of software update soon. Well the first time it was running hot, it was not responding to via HTTP or SSH. It just crash and continued to run hot. So if it has crashed I'm not sure it would be able to monitor the temp and stop at 80C.
Could be a problem with board J7; as a previous contributor of this forum mentioned earlier. |

I had a situation with my S4 2 days ago where I was changing pools and after I clicked save & apply it crashed.I could not access the web interface nor was it mining to any of the pools. It took me about 2 hours to get to where it is stored and it was running quite hot and roaring like it was trying to take off on a runway. I did a hard reboot and monitored it for an hour. Everything seemed to be running better than before since it was now hashing around 2.1TH instead of 1.9TH so I went back home. After about 3 hours running I noticed the temp rise on 1 board from 49C to 61C. I was not able to get to the miner to reboot it again so it ran all night like that with me stressing. As soon as I could get to it I hard rebooted again and monitored it for about 4 hours this time. Every thing seems to be running normal again with the boards at 51C and hashing at 2TH now. I would love to know what could cause this so I can try not to do it again...  How can I remotely stop the antminer? I know I would only be able to stop it if I can connect to it, but when it is running hot and it seems like something is wrong I would like to be able to stop it so it does not damage itself. First off, your IP Address provided to you by your IP needs to be a static IP instead of dynamic. Mine was dynamic with charter communications. I had to upgrade to a business line with them to get a static IP. I'm paying $21.00 higher each month for it. The plus side is if my internet goes down, they are supposed to have me up no more than 4 hours later. They give business subscribers higher priority over residence. Once you have a static IP, I would recommend you going to youtube to see what you need to do to connect to devices (your S4) through your router and/or switch that are connected to your modem. I'm saying to go to youtube because of so many different OS's out there; versions of that OS; routers, etc... I'm assuming you are set up for DHCP. You would need to know what address was assigned to it or that you manually assigned to it in your settings so you can connect to it after you connect to your router via the static IP address. The router would have to be set up a certain way, etc... That's why I'm saying go to youtube after you get static (same IP address all the time) instead of dynamic service, which changes the IP address all the time. For instance, this youtube video tells me what one would need to do in a similar situation you're in with an Apple Airport Extreme Base Station: http://www.youtube.com/watch?v=gpeRdji4BmMYes, they talk about connecting to other "Mac's" within your house or business. You can also connect to any other devices assigned addresses in DHCP in Airport Extreme Base Station. However, you first need a "static" IP address to connect to the Base Station so you can connect to other devices through the Base Station. As for what could be wrong with your S4, I have no clue. Not my expertise. Good Luck! Wait until others wake up and head to the forum to read new posts. Then you may find your answer. I have got a static outside IP as this is a business premises and I have set the S4 to have a static inside IP. I have port forwarded to 22 (SSH) and 80 (HTTP) of the S4 IP. I can assure you there were no network problems as I run my own servers for hosting, so I hope I know what I am doing there.  I'm just hoping someone who has played around with an S4 a lot or staff from BitmainTech would be able to shed some light on this matter because so far this has not been easy to manage remotely with the issues I have been having, for example with 1 board randomly over-heating when compared to the other 3 and hash rate changing after reboots. After reading the posts about the voltage regulators not functioning like they should I am a little worried this might be a similar problem or the same thing. And with the stock power supply already close to max it's not good if it is. I could be wrong on this: I would believe your network the S4 is connected to would need to be set up for DHCP and you know the address assigned to it [whether it was assigned automatically or manually as in my case] in order to connect to your S4. Bitmaintech is not responsible for what you do with your network set up and whether you want to connect remotely or not. They are only responsible for the unit.

One more question:
In your opinion, is there any harm with leaving it at the default configuration as is?
thanks a lot. answer is simple, if device havent got any problem default config is useful but you can see my pics i replace all stock screws too, because all of stock screws is big for this pcb and these are not tight. if you open this case you can remove with your bare hands. poor fabrication. not torked. I'll need to get my multi-meter out then and do what you did. Thanks again. |

Others perfecly normal only J7 connected hash board is unconfigurable, if you want to proof of that disconnect this board power cord and you will see chain 1 is gone and look at your power wattage. or try to configure voltage and repower again. i have 2 S4 and all of them have same problem.
and i found best configuration and best efficiency (0.52 but not stable) => 187.5 Mhz at 0.685 Volt (you can add this value like that = 0685)
this is the best...
Curious: Does this also mean board J7 will remain at 0.725 Volts while the others are at 0.685 Volts? Cause I think you said J7 was un-configurable? This would mean we can expect this one board to probably be considerably hotter than the other boards. Yes thats right. i can measure stable results, only after i found a master problem and solve it And the way to solve it [for now] is to reduce to 187.5 Mhz at 0.685 Volt? Just making sure you did not do something else as well? No... that is not a solution. this is my best working parameters. not a solution........ That's what I thought... I was just making sure. Thanks again for your patience; time; and hard work. |

of course that is lower than 2Thash but also eat lower energy and also lower Temperature and lower noise like 1800Ghash 1060W I was just about to ask you for the actual hash rate and wattage. Thank you... |

Wow! So, you recommend all of us with batch 2 to switch to 187.5 Mhz at 0.685 Volt? Will doing this lower my hash rate? If so, by how much will it lower the hash rate? |

Hi everyone, i have got a strange problem with my Antminer S4 batch2, i listed founded problems: 1-my S4's has different connections with FPGA controller, one of them is top left hash board connected to J7, other s4 same board is connected to J6. this is very strange or poor assembly. 2-this J7 connector is going to the first hash board i think, but other hash boards red led is off except this J7 connected board led blink. 5 minutes waiting then this board getting hot and another five minutes all boards leds are on. then all of them is hot but THERE IS NO ETHERNET CONNECTION. 3-i worried power comp. and i changed 0720 to 0700 then i measured all hash boards voltages on 1500uF/2,5V capacitor.. wouuwww THERE WAS A PROBLEM! because we can never change 1 hash board's (j7 connected) voltage. this is allways 0750V. than i read confidential pdf of CSD95372B and TPS53641 this is i2c controlled buck converter and this is controlled by pic12f1822 on every hash board. So this 0,750 Volt i measured is over voltage protection limit. i am an electronic engineer by the way. I ASK TO BITMAINTECH, WHY OUR HASH BOARDS HASHING SOMETHING STANDALONE (or why warming up) AND WHY 3 HASH BOARDS VOLTAGE CONFIGURABLE BUT 1 IS NOT ? thanks, any ideas ? Dogie said to me "paste pictures to forum" then i did. Now any ideas for this?  when i did sniff controller->buck i2c communication, i will make a seperate or online live voltage changer ): software bugs are minor but we have got a major hardware bugs.          Any symptoms prior to this other than ethernet going out? Such as 1 or 2 boards much warmer Celsius than the others, etc...? |
