You won't get any rewards mining to cksolo unless you find a block and then you get 6.25 btc + transaction fees - pool fees, but your hashrate shows 50 something GH, which means you will probably not make anything even mining to a PPS pool, what device are you using?

Sorry, your calculation is not wrong, bad wordings (as usual) on my end, excuse my English.


Then you have 277v*280a * 3 * 0.8, that's roughly 185kw in total, but you have bigger problems to worry about, most mining gears won't work on 277 volts, IIRC someone mention 255v was good on some T17 but not all, I think most folks who have 277v use Microbt gears, of course, not all Microbt gears support 277v but they do have a few options like the models that use p21 PSU, I had this voltage conversation like a year ago, and I am a bit too old and my memory isn't so great, so take the voltage info with a spoon of salt and do more research in that regards.

Sadly, both BOs and Vnish have not finished the S17e and T17e firmware (they have been saying it's coming soon for a very long time) which probably means it's not coming at all, but thierry4wd has a modded version, you might want to give it a try.

I am not from the U.K nor have I  seen a 480v transformer but I have strong reasons to believe that you made a mistake in your calculations, I am almost certain that you can't have 480v between each phase and neutral, 480V is between phases, and 277v or 240v if it's high leg delta between each phase and a neutral.

This means the math has to change to 240 or 277 * 280 = either 67,200kw or 77,560kw if it's 277v, and since you can't really go past 80% load, I'd guess the transformer will only be happy with at a 20% reduction, which is either 53kw on 240v or 61kw on 277v, that will be a total of 159kw or 183kw.

Now if I am wrong, i.e you really get 480v between each phase and N, then the number of miners you can run on this transformer is exactly ZERO because no miner on planet earth works on 480V.

ِAbonded is for the whole project, it simply means they are no longer maintaining the project, ignore that. but judging from the code on issue #16 I see no reason why it shouldn't work, your code, however, which you posted here > https://imgur.com/v7hu2lm is missing a for loop and doesn't seem to be passing the worked id, is the screenshot outdated or you modified the code?

What error does it through? do you get err-msg?

I think your userlist code is incomplete, the count function in php only returns the elements count of an array and not their assigned values, I am not sure how are you passing the user id in the code you posted the screenshot for, could you paste it here so I can have a better look.?

I believe you need to use a for loop to go through workers, can you just use the exact code that SwimmingTiger posted here > https://github.com/btccom/btcpool-ABANDONED/issues/16d

Did you check on zeusbtc.com? I think most suppliers are facing chips shortage, it seems like thousands of gears were sitting on the sideline doing nothing until BTC took off and everyone wanted to fix those gears, I think you can actually extract the chips from one of the boards you have, say you have 10 bad boards, you sacrifice 1 to fix the other 9, makes any senes?

if this works, it will add an extra step or two on the process, but at least you don't have to wait forever to find the chips.

I really have no personal experience on this but most set-ups I have seen do remove the fans, and then you will need to use a fan emulator to trick the miner into thinking that fans are spinning at the needed RPMs because the miner won't start before the fan-check is passed, or you will use custom firmware like Vnish where you can disable the fan-check test, but of course, you pay 2-3% fees for the firmware.

I have seen a few videos on youtube before that look solid, the majority are people who do it for the views where they put a miner in a fish tank and stuff like that, but some solid operations do it professionally, just dig a bit deeper and you will find examples.

I would add https://service.myrig.com/ to the list if someone I trust can vouch for them, NFW I do trust your judgment but since you mentioned that you used them "long long ago" things could have changed, and the quoted post below makes me doubt they are still as good as they used to be:


Their account was last active on "March 06, 2019, 09:42:34 PM".

Can someone in the U.S reach out to them to the new phone number they have on their website ( a different one from the one posted above which is disconnected) to see if they still offer repairs?

This number +1 720 744 30 90

The general thought is "the cooler the better", although as one member here tested before, if your miner runs too cool it will increase the voltage to keep the miner warmer and that will increase the power consumption, to me personally, I believe the S9 doesn't give a fudge, I have seen people run them above 100c for a very long time, I believe the 70-80c range is good overall, and anywhere below 90-95c is acceptable, don't worry much about the S9s, when they work, they are rock solid.

Here is the problem:


S9 hashboars have 63 asics on each, if 1 or more is missing then the control board will shut down that hashboard (there are a few expectations as to which domain the asic belongs to but that's nothing to be concerned about for your case).

There isn't much you can do, you need the tools and skills to physically identify the bad chips and replace them, you could try this version (Antminer-S9-all-201711171757-autofreq-user-Update2UBI-NF.tar.gz)as it might bring one of them back to life if you are lucky, if not - then well, too bad you have two dead hashboards.

Since the hashboards on T17 suck a lot of power, they had to use busbars instead of wires, of course also to improve the efficiency, your method will work as long as it's just a theory, but when applied in a real-world, it will probably fail, you see the output of that PSU is DC, and it outputs anywhere from 14.5 to 21 volts, DC connections are meant to stay as short as possible and it's hard to transmit, well the main reason why Edison lost the war of the currents 140 years ago.

If you measure the voltage on the furthest hashboard which is usually chain 2 ( in 0,1,2) you will see that it has slightly less voltage than the other two, by lengthening those busbars you will cause the voltage to drop even further, and since you want the miner to be inside a box and the PSU outside, then we are talking about a quite a bit of distance which could result in a very low voltage output which would indeed cause problems.

Now depending on how smart your design is, and say you won't add much distance, you might get away with it  


They are plated copper busbar, which is exactly what you have to use, you could use any plated copper bars you find but when you will have to tin/plate them after you make the wholes for the screws.

Honestly speaking, I would ditch the idea altogether, just throw the whole miner inside the liquid.

NotFuzzyWarm and HagssFIN would probably add more info and/or correct me if I made a mistake somewhere since they know about electcity much more than I do.

Sorry for causing confusion, I tried to be detailed ended up making things a bit hard to understand, but you kind of got it anyways, to put this in even a simpler form, just plug the second PSU into an outlet, take 3*6pin cables and plug them in the 3rd board which now is unplugged.

You could also connect the control board to the second PSU instead of connecting it to the first one since the second PSU will have a lot more room, the control board doesn't consume much but still worth it IMO.

تاريخ اعلي قمة: شهر مايو
قيمة اعلي قمة: 134 الف
نسبة التصحيح المحتملة: 70-80%
السبب: طبيعة دورات الاسواق الصاعدة التي تتكون من فترة تجميع, صعود وتم انهيار.

التحليل الذي اعتمد عليه في هده النظرية الخرافية  هوا هدا



كل شمعة من هده الشموع تمتل ربع سنة اي 3 اشهر, نلاحظ ان حوالي 80% من الوقت تكون البتكوين في المنطقة الخضراء وهي مناطق تجميع ومن تم تدهب المنطقة الصفراء استعدادا لانهاء الدورة وهده المنطقة لا تتجاوز شمعة واحدة اي 3 اشهر كحد اقصى وتمتل حوالي 20% من الوقت التي تقضيه البتكوين, اما المنطقة الحمراء فهيا نهاية الدورة والتي لايبقا السعر عندها لاكتر من 10% من الوقت, ويكون فيها الصعود سريع والهبوط اسرع.

نسبة التصحيح ستكون مرتبطة بالوقت التي تستغرفه البتكوين للوصول الى القاع, ولكن لو كان التصحيح سريع جدا فسيكون اقصى تصحيح ممكن هوا 35 الف, اما متوسط التصحيح من وجهة نظري سيكون في حوالي 40-50 الف دولار للبتكوين.

انا لا اختلف معك في الارقام ولن اتفجاء بصعود البتكوين الى 100-150 الف, ولكن ما اقصده اننا في نهاية الدورة هوا من حيت الزمن وليس السعر, عندما قارنت مايحدث الان ب 2017 فهو بكل تأكيد ليس مبني على الاسعار بل بمؤشرات قرب القمة من حيت الزمن, اتوقع ان نصل لنهاية الذروة قبل منتصف العام على عكس المعتقد الشائع وهوا نهاية السنة,  يوجد الكثير من المؤشرات التقنية التي تبين قرب نهاية هده الدورة ( يمكن مناقشتها بتعمق ان اردتم ذلك وربما تكون في موضوع منفصل).


لازلت اعتقد ان اغلب المستتمرين هدفهم الربح السريع, ربما يكون البعض يبحت عن التقنية ولكن هدا لا يغير حقيقة الاغلبية, على العموم سوف نكتشف كل هدا بمدى التصحيح عند نهاية هده الدورة, ان كانت عقلية المشترين قد تغيرت عن 2017 يعني اننا لن نشاهد تصحيح بنسبة تصل الى 80-85%, وان حصل تصحيح بهدا الحجم يعني ببساطة انه لم يتغير شي عن 2017 باستتناء "حجم" الامول لهدا العام. وطبعا انا اتمنى ان اكون مخطاء وان يكون التصحيح مشابه لتصحيح اسواق الاسهم وغيرها.

اما بخصوص الاستتمار في البتكوين بشكل اساسي فنعم استحواذ البتكوين الان حوالي 60% الان, وهدا رقم جيد نوعا ما, لازالت هناك مليارات الدولارت يتم استتمارها في Defi and NFT ولكن يبدو ان بعض الناس تعلمو من اخطاء الماضي وان معظم العملات الجديدة تنتهي بالزوال.

You could try, you lose nothing, thierry4wd said he could extract the hex for the basic S9 version in this post, try to reach out to him.

The APW7 puts a decent 1.8KW at 230-240v, so the max you can achieve on a 110v would be under the 900w mark which is not enough to run 3 hashboards at least not on the default settings.


I don't see why not, as long as every hashboard is connected to just one PSU, so every 3 6pin going into a hashboards are from the same power source, and I assume you will need to power the PSU that does not power the control board first.

Phill as I said earlier, I do like the theory and I see the logic, but with Bitmain stuck in a few contracts to deliver tens of thousands of bitcoin mining gears which they have not delivered even half, don't you think that will make it difficult for them to focus on something else, at least the size you anticipate.


Nicely put, and $ to hashrate is the backbone, no?

Not to discuss the effect of heat on plasterboards, but this makes no sense, if your mining room is hot enough to damage anything, it will simply damage your miners first, if you design and build a farm with proper ventilation the place can't get too hot, I used gypsum board on one of the smalls farms I built and had zero issues.

This is normal, the hashboard is dying, it will work for a while, then stops, sometimes a reboot brings it on for a while, and then it sleeps for a while, and so on, eventually, it will just die forever.
