Since you are using Awesome miner to monitor/control, try editing the Miner Offline rule to use 'Start Miner" Instead of "Restart Miner. I just started trying that and so far it seems to give the miner a kick in the pants without doing a full restart/warm boot.
Sometimes a miner shows offline in awesome and I managed to kick start them through putty: reboot -f -p That works in many cases when miner shows offline in awesome and even when you cant browse the miner through the GUI. How do you make this start command in Awesome you are talking about ? Be on the Main tab, select Options > Rules. You get a menu with pre-defined tick boxes as well as an area below to write your own rules.. From the pre-defined list double click on Offline Detection to edit what it does. Same applies to Dead Device Detection -- you can edit how many chips report bad before choosing what to do about it. Like I said, for Offline the default was restert which rebooted the entire miner. Changing to Start miner I think just restarts cgminer itself. There is prolly a description of what the API calls do in ck/Kanos github... So far looking at the logged stats, since changing Offline Detection to just Notify and to Start Miner (vs Restart) none of my miners have rebooted since! Ja the Notifications are logged but looking at the performance loge for times involved show no hash rate lost and miner uptime reflects happy running as well. With the 8 s9's I have and several s7's as well I'd see at least one per-day reboot due to offline timeout. Now - zero  |

I wonder how much it would freak out if you used an external PWM fan driver and piped through the tach line so it would still see the fan spinning?
Yup, I am thinking of something like that. Right now I have noticed that the tuning process can complete with only one fan online, while the other is unplugged. But bmminer stops immediately after tuning completes, and puts out an error message, when it detects a single fan. Since other folks have mentioned the fan speeds change from time to time, my thought is that the firmware might be trying to maintain a specific 'best' chip temp to keep it stable. IF so... |

I will say there was some delay getting me updated datasheets because the manufacture batch had been changed from the sample batch. I don't really know what the changes were but presumably they were improvements. So if Bitfury took an extra couple months stepping things up a notch I'm pretty sure that's a good thing.
No doubt. And since BitFury has their own massive private perfect test site, I'd think all the various iterations of the chips that they got from TSMC got a pretty decent amount of testing en-mass to work out the wrinkles  |

i replaced the psu to another one used on B600 and they both work correctly now!
i hope this issue wouldn't return
Cool. Query: what PSU's are you using? I've pretty much have mostly used Bitmains 1,600W ones and some are getting very long in the tooth... At least one that was powering a s9 b3 had to be swapped out with a bit newer one (previously used on a s7). Miner seems more stable now although even at worst dropouts were maybe 1 every5-6 days. |

As far as Bitfury goes, I'm not really sure what (from the little I know) I'm officially authorised to say or not. Pretty much all I will say is they got me samples and datasheets and I'm already started working on new stuff. I figure that PR can't possibly hurt them within the community, because it's about the first real effort any major manufacturer has done proactively to help the community in about a year. I agree 100% esp. about the PR. Truth be told, I'd leave current information to what you've released so far. Too many unknowns lie ahead for now Ja for whatever reason(s) BitFury massively missed their mark on matching chip delivery with Bitmain but OTOH that has also given them time to see what problems Bitmain have with the 16nm node and then apply that information to BitFury's chip. Since I believe historically BitFury chips were mainly used for their own let-us-build-you-a Farm sales/projects they were the only ones really hurt by the delay. It will be interesting to see how the chips work in the Real World. |

I was thinking more of maybe reusing the buck inductors from the old miners more than anything. That is assuming they can the deliver the needed currents of course. Fairly easy to remove with near-zero chance of damage.
Und ja, I'm one of those who these days would prefer buying pre-built. I did 2 of the s1 > s3 upgrades and it was a surprising PITA... Mainly removing the old heatsink compound and re-pasting with new. Not mention having to wear armored gloves when doing it 'cause damn those fins are sharp! For your production I highly suggest making a frame/jig to hold the heatsinks for cleaning/re-pasting...These days, it's just not worth my time/effort/blood and I am happy to pay for someone else to do it.

If it is by the AC power inlet on the PSU I believe it means the PSU has a fault. Been a long time since I've ran my s4's so could be wrong...

i went to boot loop now
every 20 minutes and before the machine start it restart by self
As others said - contact Bitmain to start the RMA process. For now -- and document all of this with screen shots --, At the bad hashboard, swap the data cable with a hashboard next to it. Restart the miner and take screen shot. Did the problem chain move? If it did the hashboard is bad. If it did NOT then either the cable or controller is bad. Odds are it's the board. Once the problem is identified I'd disconnect that 1 board/cable so the remaining 2 can work properly. DO NOT BREAK THE WARRANTY SEAL UNTIL BITMAIN SAYS YOU CAN!**TIP** unplugging the data cable can be -- difficult. You need to squeeze the long tab very firmly to disengage the hooks, then rock the connector back and forth as you pull. |

What software is this?
If you are referring to the monitor software -- it is Awesome Miner from Awesomeminer.com. I also use it and gotta say - it's great and well worth the 1-time cost when controlling >4 miners. 4 or less is free! |

Faboo! Glad to see that at least BitFury has started to open the door for 3rd party miners using their chip. In 1 respect it suggests that the chip should be at least reasonably stable. a cgminer driver for a 14nm Compac I won't be able to mass-produce because the chip supplier has decided not to sell to third parties.
I assume you are talking about BW's chip. In a way it doesn't surprise me that BW is keeping it to themselves or at best sharing with a very few select mega pharms. Given the problems that Bitmain has with their 16nm chips I'll bet ya BTC to beans that the 14nm chips are even more temperamental. At least this way BW gets to eat their own dog food -- and keep any issues the chips have out of the Press. ayout work has already been started on a "pod" miner that I would like to see hit 700GH, and the same framework can extend to S1 refit boards that, I'm just spitballing here, could see 4-6TH per pair depending on the chip specs and final configuration.  I assume you still have that pile of s1's I set out to pasture with ya? Makes for a nice stable supply of cores to use. Any of the VR parts to be used from them or just the frame & heatsinks? |

What does the HW mean, on one chip it seems higher than the others??
HW means Hardware error. As to what it can be --- many possibilities. Best to just Google "bitcoin HW error" |

Along with the ASIC strings on the board running different frequencies, the gods forbid, is EACH ASIC's speed different as well?? Sure looks like it to me otherwise what's the point of recording per-chip speeds? Is it even possible to do that (different speed per-ASIC)? I'd think that it would raise hell with timing the data xfrs... If this is the case then the boards reported speed is the average of all speeds being used on the board. |

@ patrike Just got a s9 batch-17 and... Bitmain has changed the firmware, is now BMminer v2.0. I will post in detail tomorrow but for a summary of changes: - They have changed the hash board channels and therefore die temp reporting channels. Now using channels 6, 7, and 8. Might need to come up with a routine to scan the die temp channels and only use ones reporting something...
- Looks like changing the frequency may be gone. In the Bitmain GUI that choice is gone. On startup, the firmware goes through several checks per-board and sets the best freq and possibly Vcore as well. When all is done, the boards report different frequencies.
Looking at the Kernel Log it shows several lists of freq and voltage it tries for each board. A note at the beginning of each list says that freq is now stored in the PIC. Now does that mean that a warm boot bypasses the testing -- dunna know but hope so. I'll post the Kernel Log tomorrow. Also fan speed no longer has a setting on the BMminer GUI. Log says is set as needed starting at 40% Oh, the fans are on different channels as well. Think fans are now reported in positions 6 an 8. I'll verify tomorrow. edit: fans in positions 3 and 6. Due to the time it takes for the new rebooting process -- around 4 min -- better set dead miner/offline/etc to wait at least that 4 maybe even 5 min before trying to issue another reboot call to the miner... Other than that, everything else works fine inc the Web access and info to it. Thanks for the update. Could you please send me an API report for one of these new miners? Then I can compare it in detail with previous batches. Many thanks! The miner is in my farm at work so will have to send the API report on Monday. I do have the Kernel log posted https://bitcointalk.org/index.php?topic=1645898.msg16564008#msg16564008and at the end of the log it shows many things I never seen reported. Thinks like range of freq's per-string and even best speeds per chip. |

Frankly, I think the performance checks are a good solution to the fact that due to 16nm process variations the chips and therefore boards have a 'butter zone' that can be substantially different from one wafer to another. It also leads to an idea of looking over a stock of miners then taking the best boards and putting them in 1 'Super' miner... Wonder what a single 3-board miner could hit if all boards can run at top speed? mebe say >16THs? So far after nearly 24hrs the miner works great  |

Please inform us if it is better than the previous batches because I am really considering to buy one that is reliable
For the most part with the S9's it seems it is a crap shoot. I have 8 of the s9 miners spanning batch 1 through 17 and most run fine. Yes 2 of them, a batch-1 and a batch-11 had a hash board die (which were repaired by Bitmain Warranty) but so far it looks like no single batch is better than another. |

Just got a s9 batch-17 and... Bitmain has changed the firmware. I will post in detail tomorrow but for a summary of changes: - They have changed the board channels used and so the temp reporting channels. Now using channels 6, 7, and 8.
- Looks like changing the frequency may be gone. There is no longer a GUI option to change it. On startup, the firmware goes through several checks per-board and sets the best freq and possibly Vcore as well per-board. When all is done, the boards report different frequencies. This could turn out to be rather -- interesting.
- Looking at the Kernel Log it shows several lists of freq and voltage it tries for each board. A note at the beginning of each list says that freq is now stored in the PIC. Now does that mean that a warm boot bypasses the testing -- dunna know but hope so.
I'll post the Kernel Log tomorrow. Also fan speed no longer has a setting on the BMminer GUI. Log says is set as needed starting at 40% Oh, the fans are on different channels as well. Think fans are now reported in position 6 an 8. I'll verify tomorrow. edit: Fans in positions 3 and 6 Due to the time it takes for the new booting process -- around 4 min or more -- better set dead miner/offline/etc monitoring to wait at least that 4 maybe even 5 min before trying to issue another reboot call to the miner... Frankly, during the setup process for miner name and pool assignments the reboots needed were taking so long that I thought the miner was going to be a DOA!  Folks, keep in mind that much longer time needed to come to life before you start to get miffed/worried like I was. A couple times when it was taking A LOT longer than was normal with the earlier batches I forced reboots trying to get the miner to respond. thankfully it didn't brick. |

If you have hard rebooted it a few times and it still comes back, you just have a bad chip. No way to fix it.
Well, yes and no. Quite often dropping the miner speed down a notch or 2 will bring a weak chip back to life. It just doesn't want to run at full speed. Only drawback is that the new total hashrate will probably be less than having the 1 chip offline, so.... I'd leave it as-is. |

@ patrike Just got a s9 batch-17 and... Bitmain has changed the firmware, is now BMminer v2.0. I will post in detail tomorrow but for a summary of changes: - They have changed the hash board channels and therefore die temp reporting channels. Now using channels 6, 7, and 8. Might need to come up with a routine to scan the die temp channels and only use ones reporting something...
- Looks like changing the frequency may be gone. In the Bitmain GUI that choice is gone. On startup, the firmware goes through several checks per-board and sets the best freq and possibly Vcore as well. When all is done, the boards report different frequencies.

Other than that, everything else works fine inc the Web access and info to it. |
