Upgrade Antminer S9 Pro (6 board) 21Th S9Dual 

And where is the advantage? Why not mine in parallel with two unmodified? Or if you want it to be more quiet, why not slow it down from 13.5TH/s to 10TH/s? From the calculations, with an original one you get $ 90.72 today, and with a modified one you get $ 133.97, excluding electricity. Why would I care about life time? These ASICs are obsolete anyway. Can I use the 6 boards version at maximum power 27TH/s, with additional cooling and double power supply? Does anyone know in this case what would be the consumption at the outlet? Thank you.

I run a S10 (s9 dual) as well. I added the extra 2 fan headers so i have 4 fans and run it off a 2800 watt server power supply so i get the full 30th + out of them. i also run another with 2 bitmain power supply's. Less configuration is really the only benefit.

Whoa. That's like a 60% increase in hashrate with the same wattage. Dude, that's awesome. So you're getting about 68 watts per TH. Normally an S9 is around 98 watts per TH. So I could do something similar with two S9j's and get closer to 23TH/s.

Muito legal, mandou bem

Thanks for the instructions, it worked 👍

Why did you change the PCI cables are they any different or just putting fresh one? Thanks for the amazing video

the s9 is 13t / h because with the 6 plates it didn't work at 26t / h? on the stamp you put 20th?

what voltaje do you use ? the only difference from a normal underclock is that u use a single computer for 2 ants basically ?? my opinion is that what you win by using just one computer you lose by using just one psu . ( the psu has the best randament when using only 50% ) , have u tried using the same configuration with 2 psu's ? haw much does one computer consume ? thank you very much !

may i know where can we get the bitmain S9 Pro sticker?

Can I disable the fan entirely to run in an immersion fluid?

You can get 25TH but not like this. To overclock you need to change the firmware for liquid cooling and custom power tuning. Tin the tops of the chips. remove all casing and fans. Install one piece giant heat sinks to both sides to increase chilling surface area. stack all six boards in a wafer and drop into Dielectric chilled fluid taking consideration for a heat convection current. Its silent, you can run it on HP power supplies and for about 3000w you can have 12 boards pushing close to 50TH at sub 45C. Now The benefit of that rig is its very stable, its silent and it costs about 400 bucks all in for 12 boards. The enemy is still power consumption but its a good way to get into the game to flip a little cash into larger amounts.

Wait a sec... So you're running 2 units together but getting lower combined hash rates than if you just ran 2 units separately? Is this because you limited yourself with power by using a small/the original PSU and don't have 1/3rd of the hashing board powered?

Does this need to be apw7 instead of apw3?

Wait. You took two 1500w units and ended up with a final product that still only pulls 1500w?... also the bump in hashrate was much smaller than I expected.

A question. To join both, do you have to do some configuration? Or do they automatically lower their consumption? because when connecting 2 the original power source would not support them

What are the cable for powersupply that you need to get? the yellow and black cable

Hey, can you upload correct picture? The old link dont work

Hello, is the power supply sufficient for two devices?

Can you please send a link to the power cords

I see 9 slots on the control board. Looks like you can connect 3 together and control them with one control board. If so would you please make a video conducting that procedure and would you also put new overclocking firmware in the description? (If that's possible.) Thank you for your time and knowledge have a great day.

Does it overheat losing 50% of fans ?

What model s9’s does it take to make this? I heard ya can’t do it with the k model

Good morning, just 2 fan ? And why change the power wire from power supply?

hello, what do you recommend to mark the hash board? It is so that they are not confused with other people hash boards. the issue is that my customer needs the mark not to be erased with the cleaning maintenance, he thinks his hash boards are being changed. Thank you

why only connect 12 power connectors to cards? and not all 18?

I tried the pro firmware you linked , everything works except the manual config in the auto tune. When ever i set a manual settings instead of a pre determine profile it says wait 30 sec over and over and never starts the auto tune . How can i fix that ? Thank you

at 4.46 resistor are not mounted on the correct chain. the lower resistor should be on the top

will this work with braiins+ like this?

So theyre "0402 SMD" resistors at 4k7 value?

i already foollow as instruction for antminer s9 modification on video but the all hashboards connected to the new 3 socket all error of set PIC flash addr how to fix it

Только мне интересно зачем это все надо ? Взяли 2 асика по 14 хэшей и превратили его в один на 21 хэш. ГЕНИАЛЬНО!!! А нельзя было просто в прошивке поставить по 11 хэшей каждому ? Или лёгких путей не ищем ?

Can the S7 run in dual mode, it has the extra ribbon slots on the control board, but I can't find a dual mode firmware, could you use S9 dual firmware ?

Awesome!

Чи можна приєднати 9 хеш плат на одну контрольку? Роз'єми додаткові є.

what is the liquid you used before soldering the 18 pin connectors

Now overclock this!

Does anyone sell these modified boards? I'd love to purchase a couple from someone who knows how to perform the upgrade. My soldering skills will not allow me to do this work.

Вы видео исправили уже? Ребята сказали что у вас в видео неправильно показано что куда паять.

what kind of cables do you replacing from original cables from power? because original cables are 10 males, but looks like you have 13 males on new cable. where do I get those 13 pcs cables?

really works with only 2 pci-x each?

Is there any modification in the power supply unit?

Здравствуйте! Где взять косы для бп с нужным количеством разъёмов?

Is it possible to order the modified control board

where do you get the sticker L9 pro

Firmware and grill drawing links don't work

Теперь схема в видео верно нарисована? Ошибок нет с резисторами..

Why not just use low power mode on two S9?

It will work with s9k??

Can I buy one from you plus any extra cables I might need

такой вопрос а блок на 1600 ОБП пойдет если по одному разъему на ХЭШплату подсоединить проблем не будет?

вопрос S9+S9J можно соединить два разные

where can get 13pc 6pin cable.

Its possible to boot from the network? instead of sd card

что за прошивка у вас стоит

Can s9k do this?

Hi master can t9+ do this too?

Why do they have to be the same

I just realized that you didnt reply to any comments of your own video.

Any way you can solder my board for a free? I really want to do this dual setup. Let me know

does this still work?

Asic L3+ реально повторить???

amigo que puedo hacer si el minero me muestra una temperatura que es totalmente falsa, es decir tengo dos s9 y mientras uno esta en 75 c el otro esta en 86 c. pero en una sola placa. aconséjame

Will L3+ Do this too?

Здравствуйте,подскажите,пожалуйста из какого металла изготовлена решетка на выдув?

а разьемы не в обратную сторону защелками надо устанавливать ??? или без разници

Can you sell a modified board?. Can i use a s9 13.5Th and another s9 14Th?. Thanks.

подскажите пожалуйста при пайке что вы используете как называется(жидкость, и металл) ? буду сам делать не разбираюсь в этом

Приветствую, решетку на выдув сами изготовили?

Do you need a custom firmware to make this work? Is there a dev fee?

I don't get it on not applying power to the back of the hashing boards, Can you please explain to us?

One good way to waste 7TH😂

Добрый день, а какие элементы идут в обвязке к разъемам на контрольной плате? откуда брали?

Здравствуйте. Прошивки что вы выложили они с devfee?

Any chance u sell the s9 pro control board??

Mmmmm.... i get about 15 th from each s9 this sounds stupid unless you use a much bigger psu or 2 of them wich will defeat the purpose just ducttape them together then

Is antminer s9 still worth getting today?

Чето я нихрена не понял ) для этого не нужно по три пина на плату соединять ? достаточно по два ?

Приветствую! 3 s9 пробовали объединять?

bratuhan, is it also possible with 2 antminer s9j 17th ?

Is it possible to do this with 2 x A9 Zmaster?

hello teacher, take it easy, I'm new to this hasbord repair business and I live in another country, can you help me with this repair business.

I would like to buy a couple of those boards if you can make me two.

Work on s9i?

Prefiero 27th no es lógico hacer eso

i see no advajntage other than less ethernet cables its good but not quite carling lol 😆

done that with a V9

No useless, S9 13TH x2 = 26 TH, you make 2 S9 13THx2=20 TH?, if your modified low fan quiet for, just set your miner for 10TH is more quiet and low electricity consumption. LoL but nice try to make content.

и это на родной прошивке?

Скрытый процент есть?

А какая прошивка?

Что за флюс?

И еще вопрос. А третий файл это что?

Удали ты эту фотку с видео!!! Там не правильно указано куда надо резисторы паять!

bratuhan, is it also possible with 2 antminer s9j 17th ?
