I am having trouble with understanding what you are saying here? this modification is necessary, because bitmain chip voltage and data voltages are different, Serial chip feeding becomes need more stable voltage.
What do you mean by "bitmain chip voltage and data voltages are different,"? when chip goes down to under 0,61 Volt then chip fried. (under 11V) if overclock your miner you must to have a lot of amperes, otherwise your voltages goes down immidiately. i add 2200uF/16V capacitor each hashboard.
Agreed that if the chip voltage goes under 0.61V / 11V Supply there could be a problem, however this is a 135 chip system which at 12V gives 0.8V / chip and at 11V it's stiil 0.73V on the chips? This capacitors filter SMPS's peak and 500Khz 12V charge time. we are talk about more than 100A. This hungry machine suck 12V quicly. and ferrit inductor job is choke inductor too. this method is more stable for silly PSU's.  Are you suggesting that the Capacitors & Inductor in the picture are the only additions to that part of the circuitry and that there is no Buck Converter chip on the other side of the board as I am guessing? Rich - Yes there are absolutly different with data signals taking from schimitt triggered hex buffers. Look at bm1385 PDF.  -i dont know which chips series or parallel on this new 135 chip board. 15 series possible. if feed 12 optimum 0.8V, if feed 10 min 0.66V. but we know this is overclocked model, finally you cannot feed 10V for 700Mhz. -i dont know but i dont think so, this is not step up or down buck converter because this coil needs large mosfets and controller, i dont see them yet |

Very interesting and not what I had expected. They have got rid of the bottom 9 chips in the chain, as opposed to 9 out of the middle I had predicted. What I do not understand is what and why that additional component (Large Inductor?) and the additional capacitors are for? Unless perhaps there is a buck converter chip on the other side of the board & we have moved away from the string design? Need a Sidehack opinion here? Or perhaps it's a hybrid with a buck converter to a slightly lower, Adjustable? voltage & then still a string for the chips? Also a picture of the other side of the board would be great? Rich In some cases, inductors are installed to offset the affects of capacitance. Especially, when high frequencies are involved. Those round components near the inductor looks like capacitors. It has me curious as well. this modification is necessary, because bitmain chip voltage and data voltages are different, Serial chip feeding becomes need more stable voltage. when chip goes down to under 0,61 Volt then chip fried.

got my batch 5 today, all setup & running well... just wanna share & i think most would've noticed the slots on the sides of the miners.
slotted 2 x batch 5 with my batch 3, just like a lego block. makes it more sturdy. like the housing.
all of them hash as advertised, stock. all pcie's connected from 4000W psu. not gonna touch anything till the 90 days warranty passes.
temps are at mid 50's. very low HW error. 0.0001%
the hashrate does jump around quite a bit but avg's out to the advertised hashrate.
1 of the batch 5 has a woong woong woong fan sound if fan is above 60% .. tried to loosen & tighten front n back fans, no fix.
another batch 5 controller has no green LED light but it works fine so i'm not gonna make a fuss or touch anything. the LED next to the red LED near to LAN port.
other than that, pretty happy. no warm cables (16 AWG custom made) or so.
can't wait to see more ideas when the 90days warranty passes. i'm sure lots of guys here are trying something & doing innovative stuff yeah ?
FW is stock sep 15. i think i saw some guys updated the OCT FW. any difference ?
waiting on the data cable to save a controller board. hooking up 2 in 1 when cables arrive.
regarding ROI .. yes it's tough & NOT impossible at this stage but later, yes but depending on individuals .... i;m gonna mine the the chips, board, etc melts away so i think i'm gonna hit ROI & prolly a lil' profit.
buy BTC or miner almost the same imo, we all want BTC go up !
you can do that too (S7 Twins) https://bitcointalk.org/index.php?topic=1165628.msg12982754#msg12982754 |

keşke o chiller in beyaz kablosunu powerin yeşil+siyah yani on-off pinine bağlasaydın. boşta görünce içim cızladı. bu durumda su dönmezse minerın yanabilir. ben verdiğimde 1000W power vardı sanırım sen 2x750 ile overclock ettin |

Garantili ve temiz uygun fiyatli 750w civari psu ihtiyacim var . 2 adet 8 pin cikis lazim. Moduler olmasi tercih nedenidir.
ne amaçla kullanacaksın ? 8pin çıkışlar CPU beslemesi bildiğim kadarıyla. |

612 mhz üzerine çıkılması güç kaynagi açısından mı sakıncalı yoksa s7 nin kendisi için mi sakıncalı ? örnek bi 700w lık psu sadece bir karta baglanıp bu guc kaynagıda diğer iki karta baglansa ve mesela hiz 625 yapılsa bi sakıncası yok heralde...
psu ların eksi kutuplarını ortakladığınız sürece problem çıkmaz, ancak PC psu ları çok çıkışlıdır(3,3 5 +12 -12 Vs..) bunlardan sadece 12V kanalını kullandığınızdan üzerinde yazan değere aldanmamak gerekmektedir. örnek vermek gerekirse sizin 700W psu yalnızca 480w 12 volt 40 amper olarak iş yapar. Bizimkilerin ise tam gücü 12V olarak çıkar, örnek 1200W sa 1200/12=100 Amper. 600mhz de S7 100A civavarı akım çeker, her bir blade 33-35A civarı. 612 mhz hem cihaz için hem de psu için yıpranma noktasıdır. 162 çipli s7 çok ısınır bu ısıyı atamaz, psuya çok yüklenir kablolarda 50Wlık kayıplar oluşur tüm sistem ısınır. s7 içindeki bonding yapışkanı ve soğutucu kayar, yandaki soğutucuya değer ve gümm. 1 hafta sonunda kucağınıza overclock sevdası yüzünden tüm sistemi alırsınız. benim şahsi tavsiyem çinlilerin söylediği değerlerde asla bu makineleri çalıştırmayın. 1-2 kademe aşağısında çalıştırmanız, gürültü ve ısı olarak hem sizin için hemde cihazınızın uzun ömürlü kalması için önemlidir. |

Mevzu delinin attığı taşa döndü arkadaşlar, netleştirim;
ithalat masrafları çok yüksektir ve tümünü son kullanıcı üstlenerek öder.
saygılar.

Selam arkadaşlar,
Şahsım tarafından elektronik olarak modifiye edilmiş ve verimliliği arttırılmış,
hiçbir zaman 200Mhz ve üzeri frekansta kullanılmamış S4 lerimi satıyorum,
piyasada bulamayacağınız kadar az gürültü ve %15 daha az enerji harcayarak 2 Th üretir.
Normal S4 1400W çalışır. 1.95 Th için freq:193 Voltage:0695 ayarında 1150W harcar.
Tüm mekanik aksam tarafımca yenilenmiş, dandik çin montaj problemleri giderilmiştir.
tüm vidaları değiştirilmiştir. tam 1 senelik Rock Solid üründür.
fiyat adet başı 2500TL ciddi alıcılar PM atabilir. Sorusu olana buradan yazabilirim.
Saygılar.
Selam arkadaşlar, iş yoğunluğundan dolayı ocakta satışını yapacağım son kalan S4 ve 3küp KNC için ancak fırsat bulabildim. S4, 225Mhz de 2,25Th ve hatasız çalışmaktadır. Ancak 2 sıcaklık çipi aldığımdan bu yana hatalı, istenirse yenilerini takarım. KNC 3 adet küp hiç hatasız 475Mhz de 2Th iş yapmaktadır. Psu ile birlikte verilecektir. Ayrıca KNC antminerlardan daha kolay kullanıma sahiptir kormanıza hiç gerek yok. 2 si için 2500TL düşünüyorum. Ciddi alıcılar PM atabilir. GG SP vadeli vs.. satış değildir. Bursa içerisinden nakit ve çalışırken verilecektir. Çay-Çorba-Yemek müessesedendir. (fakat on kişi gelirseniz sadece çay içersiniz) Saygılar. |

5 e al 8 e sat temiz
bak güzel kardeşim hesap yaparken bir sürü parametreyi de değerlendirmezsen böyle ufo gören masum köylü gibi yorum yaparsın. ben firma olarak İzzet beyin cihazları için PSU ihtiyaçlarını karşılıyor ve bazı teknik konularda kendisine nacizane destek oluyorum. aramızdaki her alışverişte kendisi hiçbir zaman borçlu kalmamış ve ödemesini peşinen yapmıştır. Bu binbir güçlükle getirdiği cihazlar için gümrüğe-devlete(kkdf-kültür-damga-kdv)-müşavire-upsye(ordino-ardiye)-nakliyeciye-gitgel yaptığı esnada kendi harcadığı benzine ve efora ve son olarak bana yaptığı ödemeleri de hesaba katarsak ve hele bir de bunları alan CAHIL ADAMLARLA cebelleştiğini de düşünürsek, SEN bu cihazı bu fiyata alamıyorsan HİÇ KONUŞMA ! |

My Internet went down before i woke up this AM.
My S5s came back online when the internet came back up...but my S7 (batch 1) didn't. I can still see it when i check it thru my LAN. All the ASICs are there and have all 0's but there is no hashing. The fans are running too.
I rebooted. No change. I switched PSUs - still no change. I did a few reboots- no change. Then i reset it to factory settings- still no change. Finally, i called Bitmain in Denver. The tech guy used chrome remote desktop to look at my kernel log , miner status etc. Then he shh'd into my rig. He couldn't find a problem either.
So I will be contacting Bitmain to see what can be done.
Has anyone else had this problem?
power up your s7 wait until 5 minute, login to your s7 copy all kernel log and send to me via PM. (include eye exmine-beeping-red led near the eth cable-blade Red leds lit??) i can resolve your situation. |

as i promised i share  J7 Chain1 Problem Solving Procedure - TURK isi - By Turgan You can see pic12F1822 mcu purpose is adjusting I2C voltage tree from the controller FPGA serial data, but our FPGA program is buggy and it cant send voltage data to J7 connected board. Now we make a trick and we take it a clean data from right board and put it on to left board. Using P1 ICSP connector pin 5. Remove R25 jumper resistor on left board then make a jumper wire between P1 pin5. Connect Left board to J7. Others not important. this is simple. Finally we can controll all of hash boards and we make s4's profitable (look at my oldest s4 posts for voltage settings)    Have a nice day |

i found and solve my beeping problem. Problem is; i modified my s7 and make a single fan so, stock s7 firmware hasnt got a Fan connection control but new firmware 23/10 has. we must to connect min. 2 fan (fan1-fan4) for new firmware finally beeper works his job and beeping very loud. i found my solution on my kernel report. then i decied to make a single device with 1 controller. but i would make a trick for controller 1 fan send to twice controller fan plug pwm signal. i dont do that.    you can configure missing beeper checkbox like this. open miner configuration page press f12 then find id=beep then double click style="display: none;" delete it leave it "" press enter finally beeper ringing appears on your page.  do what you want and save apply. (but this is not only 1 bug, another bug is this config is resetting with your frequency change. i said this 1 years ago for S4) i dont recommend disabling beeper but when a pool down this ring like a hell. beeper works this problems: -pool down -internet down -fan down -temp high (over 80C) (this issue is over 79C, everyone says my device is not hashing or stopped because it is.) and also some lm75 temperature chip send faulty temperature data to controller.   this unit : 9.1Th 562Mhz Fan%54 170A 12V - 2250Watt from Wall and i also shared S4 J7 Chain1 Problem Solving Procedure, like i promised, sorry for delay https://bitcointalk.org/index.php?topic=796839.msg12983094#msg12983094 |

hi everyone, finally my s7 4.66 came. i remove all and inspect everything. but chips has a bonding glue, i couldnt see any. so there are 18series 3parallel chip on each hash board. 12/18=0,66V ok i am working at 11,75V(0,65V each chip) 512Mhz %50fan speed > 4,1 Th at >1020W stable 60degreesC (room condition is 27dC) but i upload new firmware, hashing stopped, beeper always beeps and 360W idle power, red led lit. i solve beeper problem from config page, but still NO HASHING. then i checked hash boards my other S7 controller ALL FINE with stock firmware. i do not recommend this new firmware because it has alotof buggy.(23-10-15) i think bitmain do that willful. we are test subjects.  when i found a solution i share here. did bitmain create any page in here for S7 problems like S4 support thread ? anyone has a packed old firmware image? because everyone talk different threads in here and hard to find who is faced with same S7 problems. can you take a picture of controller board for me? maybe it can be different (my hash boards labeled 550 before but another sticker put on 575 after. |

hahaha harikasınız çocuklar yaa  bir de şunu düşünün adamlar 3 günde 1 amerikan dizilerini bedavaya çeviriyorlar, isimleri orada yazsın düşüncesiyle bu nasıl... Emin misin? Dizimag eskiden, şimdilerde dizipub vs bölüm başı dakika x 1 TL'ye ödüyor genelde Eğer dizi popülerse bu fiyatlar daha da artıyor. inan gençlerin bunu karşılıksız yaptıklarını sanıyordum. dizi başı 50tl hiç fena değilmiş. tabi benim verdiğim örnek bu gavurun işini bedavaya yapın anlamında değildi. asla.. |
