Just throw a reminder here to power the control board after the hash boards are up if possible.
The bitmain wording was recently changed to something more along the lines of apply power to the power supply feeding the hash boards first, and then the control board.
Many have suggested this has to do with the issues people are seeing with low hashrates.
Personally, I follow their instructions to the letter, and even to the point of using a different power supply to power my control board on my S5+ so there is no doubt about my hash boards being powered first. I am not wasting the leftover power on the power supply I use on the control board, as I am also powering a couple of S5s from it was well.
To comment on the low hash people are experiencing where the soft boot seems to pickup, I have this exact same experience with some S3s where it is truly exaggerated behaviour. Literally a hard boot shows a hash rate of a few ghs, where a soft restart allows them to operate correctly. I have seen some of the same but not as bad behaviour with my S4s, and once I knew what to look for I see it with the S5 as well. I have no doubt there is an issue across the board which causes this scenario, but as for it being tied to when the control board is powered on, I cannot say. Whether this has to do with the S7 as well I cannot say as mine is late.
Good luck to you!
Have ONE s7. I'm running it on one bitmain 1600 watt psu. I'm going to try using two corsair rm1000 psu's with one on two hashboards and the other on one hashboard and the controller. I'm going to fire up the controller psu first and then the 2 hashboard psu and see what it does. Then I will do a soft reboot and see what THAT does. Ok here we go. I have a batch one running 575 as shipped. Has been 4600 for days (5 or so) Power on corsair with controller and one hashboard. Wait 5 seconds Power on corsair with two hashboards. After 15 minutes 4600 Soft reboot After 15 minutes 4600 I don't understand the hashboard first thing. Maybe 15 or 30 second delay between power on? I think there are two separate things being discussed. 1. There is an issue with the S7s where they will not hash higher than 4600 ish. It has been suggested that slightly low input power may cause this. I recommend checking your input load at the psu connection at the miner. If you are handy with a meter you may have meter leads with needle points and you may get in the back side of the connector, or, if you have a single going to a Y cable connecting to the miner, measure the unused end on the Y connector. Phillip shows pictures of this in a couple of threads and he has presented this theory regarding the voltage. 2. Phillip also brought up the fact that a soft restart may help this issue, and I believe it has for one or two people with the S7. I was commenting in this thread to the other gentleman that I have seen this issue with S3s where it is pronounced. IT is usually the worst if I have a quick power outage, just long enough for the miner to know it was off for a second. on some of the S3s it literally shows 3 or 4 ghs for the main average, not the 5s average, it usually shows a normal number for the 5s. I do a soft restart and it begins working correctly. I saw some of this with my S4s, but not the literal 4 or 4 GHS on hard boot, just poor performance until I performed a soft boot. The same with some S5s. I cannot say on the S7 as I am waiting. 3. Then of course the power on the hash boards before the controller. This is an instruction bitmain began passing with the S5+ and has now continued with the S7, but unfortunately we have been unable to get any clear indication from bitmain as to why so we understand their intent. In the latest statement I read, I cannot remember if it was their website or the S7 manual, but whichever states to the effect of if using multiple power supplies power on the hash board power supply first and then the power supply for the controller. The way it is worded it It didn't seem to be an issue if you happen to be powering hash boards and controller if it happens to be on one power supply, but if it is separate power on the controler last. I am sure their engineering team have a good reason for this, but because we have experienced issues with translation along with the fact bitmain has a poor record of communication we are left to theorize and try to interpret what they mean by these things. I know my input power is strong to the power supplies, and to the miners, and I have no issues with #2 because I began seeing that issue with my first S3 purchases and have been soft start everything after a hard start anyway. Hell I like to be up close with my miners after I boot them. I have shortcuts setup to get me there quickly so I can look at everything. I'm a bit anal like that so it works. I think your main point here would be to check what Phillipma mentioned regarding power at the pci connector to the miner. Feel free to PM if I can help in any way. |
Transaction fees go to the pools and the pools decide to pay them to the miners. Anything else, including off-chain solutions are stealing and not the way Bitcoin was intended to function.
Make the block size set by the pool. Pool = miners and they get the choice.

I think your main point here would be to check what Phillipma mentioned regarding power at the pci connector to the miner. Feel free to PM if I can help in any way. I can tell you when I managed to get my shit numbers my pcie cords measure 11.69 volts . when I unplugged and replugged every connector and used nine 2 plug cords did the soft reboot after the hard reboot my cords went to 11.96 volts vs 11.69 volts my errors dropped to 0.015x vs 0.11xx and hash went to above 4800 with power used at 1200 watts. So I really think you absolutely must know that your pcie cables are over 11.9 and not under 11.7 when under full load to be sure it is bitmaintech's fault. I have been able to duplicate good hash at 11.9 or more volts after soft boot everytime I have been able to get bad hash at 11.69 volts every time. It is late and I am tired and showing on one machine is not good enough. I am getting a batch two machine soon I will test it and see if I can manage to get it to do proper hashing with proper volts. or if it fails to hash correctly with say 12.01 volts at the board and after a soft boot. I can use this psu https://www.trcelectronics.com/ecomm/pdf/hrp600.pdf run 1 board and be sure of power to the boards. I can even go to 12.5 volts at load to see if it does proper hash I truly suspect that this issue is a: voltage problem and a soft reboot problem blending into lower then normal hash. |

Dear loyal customers,
We're sorry to inform you that we didn't make the shipment of some orders today as promised. When we did the last spot check, we found some issues which cannot be delivered to you directly, engineers are working on it now and shipment should be arranged before end of next week.
Due to this trouble, we'd like to offer you the compensation following 97.5%*PPS payment according to the total hash rate of miners in order, starting from Oct. 11 Hong Kong Time, till the real shipping out date(which is not included), with electricity cost deducted at the price of $0.098/KWH.
The accounting unit is Bitcoin in the calculating, while USD is considered as a foreign currency. The day to day exchange rate will be get from Bitstamp daily average.
The final payment will be after we have collected your payment address, and we will inform you the way to confirm your receiving address with us.
After collect all the necessary info, we'll process the refund by batches, please wait for update patiently.
Apologize again!
How do we take advantage of this? |

Makes you wonder if they would be better with say 12.5V? Rich |

Just checked my Bitmain account and my order from 9/8 is marked shipped but UPS shows no such item in their system. EDIT: wondering since they are talking compensation for being late if they have done just what someone else said about just printing labels. will watch my UPS account closely to see when the package enters their system. Sounds as it very well may be another week before they ship. Dear loyal customers, We're sorry to inform you that we didn't make the shipment of some orders today as promised.

I just checked mine. I ordered 09/03/15 at 06:05am. It is marked "shipped."
I too have a UPS account but nothing is shown as being shipped.
My 9/4 and 9/6 batch also now show shipped, however, UPS does not show them scanned inbound yet. We create shipments out of our warehouse all day, but none of the UPS trackers will show up in thier system until we close end of day and upload those shipments from our terminal, so it ulikely any of the shipments Bitmain is doing today will show up on UPS until close of business Monday China time. If I were them Id be marking those orders shipped as fast as possible in their system even if they were not going to physically leave the warehouse for half a day. I imagine we'll have trackers by Monday afternoon EST. If we don't, we'll know what they did. By the way, all 4 of my batch one rigs are running 4.86 at 600 two weks solid now. I do have to softboot them after powerup to get them to run at100%. We're running them with brand new EVGA 1600 Golds each with a dedicated 20amp circuit from the panel, and it makes me wonder if these units are not particularly power sensitive and voltage issues are mainly causing some peoples underhashing problems, especially with all the talk of running them on two, maybe three power supplies, some different brands and many used and possibly worn out. Check those voltages at each lead as per what some of the other users are posting here as good voltage levels. Finally, I cannot fathom why anyone would buy a $2000 miner and try to cobble together some cheap power solution out of what they have laying around. A brand new EVGA 1600 is around $320 and will be consistant, rock solid, and will allow a desirable 25% power overhead for 100% uptime. After a year it will still be worth $200, so what is anyone really gaining by trying to run a smaller PSU up against the wall or powering the unit from multiple smaller units. I'm just saying this because I run 32 S5's and have all but 6 of them on their own EVGA 750's. Those we do run 2x each 20amp circuit, and have had zero iasues even when it was 80 frigin degrees in the warehouse all summer. The other 6 run split off of 3 EVGA 1300's, and those 6 are the only ones that have had hash boards go bad (2) running about 9 months now. I think there has to be something to that so when we ordered our S7's I made sure to get each one a new 1600 PSU rather then try to recycle our old ones or run them off of 2 smaller units. Time will tell, but just a thought. |

8-)
was not such a big temptation for me at 13.5c kwh and 100 amp service (2 titans at 2500w already) ie poof goes the panel in a puddle if I'd plug one of them S7's in  also the RMA to china w/o a pay and swap components option (ie you pay for say controller board to be shipped soonest and you get credit when it arrives off credit card) also not thrilled by 90 day warranty so yeah ...would be an evil temptress thou .if they had like a 'store front' of them like too blocks over thou (I've done dumber stuff impulse buying) but alas home mining is all over for me (sits in bleachers watches the asic parade go buy) |
Old Style Legacy Plug & Play BBS System. Get it from www.synchro.net. Updated 1/1/2021. It also works with Windows 10 and likely 11 and allows 16 bit DOS game doors on the same Win 10 Machine in Multi-Node! Five Minute Install! Look it over it uninstalls just as fast, if you simply want to look it over. Freeware! Full BBS System! It is a frigging hoot!:) |

Perhaps, but getting new PSU every time you get new miner could eat into your ROI. Granted, if two EVGA 750 are worse than one Evga 1600, than OK, but I don't think that you or someone else knows it yet for sure. Regarding running 2 S5 on one EVGA 1300-haven't done this, but I did run two S3 on one EVGA 1300 for months, so maybe the problem was with those machines and not PSU, but I digress. |

I planned on ordering a second unit but definitely not happening until the one I paid for already arrives and some sort of compensation is provided whether it be coupons or whatever. The lack of communication is the most frustrating part.

Curious, does it have a date marked for shipped date? I just checked my account and it says my order is shipped, but with no tracking number. There is a date placed in the send details of: Date 2015-09-28 00:00:00 No, it just changed to shipped in the past 8 hours - definitely NOT 9-28 and where is the tracking? I hope they don't attempt to compensate based upon this supposed ship date. |
