There are two main reasons i am doing this for. First is the prospect of being better able to overclock and second,  the much lower noise in my small appartement. I set up two big radiatosr with much more fans, instead of the four strong ones of the two antminers. This is just my first test setup and if it works well, i will plan up two three of those exact same setups.

Well, now it makes sense, see I don't have a problem with immersion cooling (except for the initial setup cost), but if it's done for the purpose of noise reduction, then it makes sense, keep in mind that you will need a custom firmware (usually 3% fees) or fan simulators to be able to run the miners without a fan, too early for this information, but you will eventually get there.

... my test results right now with the rising price show me an actual higher income, even with the ever increasing hashrate.

I would love to see your test results, mining profitability is in a downtrend, it has been since the beginning, so on average your profit today is better than that of tomorrow.

There are exceptions to this trend of course, but overall, 90% of gears I owned throughout the years have always made the most profit when I have first got them.

Maybe I should send 1/2 and hold the rest  for six or seven more months.

Works for me, I don't think anyone will have a problem with this wise decision, sending 50% of the funds now is a great idea, should price tank - we won't go below the upgrade requirements, if the price goes up we can pay for a few more years.

What pool exactly telling that it's rebooting every 5min?

I think he means the hashrate reported on the pool appears like the miner reboots every 5 mins, not like he is getting an email from the pool which states so.

Try to mine to another pool like ViaBTC or try the ASICboost pool on Nicehash it looks like this.

I think at least 90% of btc mining pool are Asicboost compatible, Poolin is indeed (based on personal experince) Asicboost "friendly".

stratum+tcp://sha256asicboost.eu.nicehash.com:3368

This will only fix the connectivty issue where pool shows dead, which doesn't seem to be the case here, also nothing has changed on poolin and nicehash so whichever issue is related to the miner itself because OP mentioned.

So this is unlikely to be caused by the pool/firmware/network or anything that hasn't changed, I am still leaning towards physical problems with the miner, I am almost sure that if he leaves chain chain 7 alone, the pool will report 1/3 of the total hashrate and it would be consistent.

في حال كان الحل الخاص بي صحيح, علينا الانتظار حتى يقوم شخص اخر بحل البلوك ثم تقوم انت باضافة رقم عشوائي و ننتقل للصعوبة الموالية؟ ام يكفي ايجاد بلوك واحد؟


احسنت خالد, وقت قياسي لهاش يبدا ب 3 اصفار,  بالنسبة للانتظار فسوف يكون بعد كل بلوك بغض النظر عن تغير الصعوبة من عدمها, يعني اننا الان سناخد هاش البلوك الذي وجدته انت وهو

00013f069a05d13d613c8851a67170147fccf1004610b25c3e971ebac06d00c9

وسوف اقوم باضافة رقم عشوائي له لاحقا, بالنسبة للصعوبة لن اقوم بتغيرها بعد, سوف انتظر واحكم بناء على الوقت الذي سوف تحتاجونه لحل البلوك القادم..



Khalid = 1+1
icy3 = 1



أجل هو فعلا كذلك على ما يبدو فهذه المسابقة ستزداد صعوبة بعدد المشاركين الذين سيوفقون بايجاد الحل قبل غيرهم و بالانتقال الى بلوك جديد بصعوبة جديدة ستصبح المسابقة محاكاة فعلية لفكرة التعدين بنفس درجة الصعوبة.

احسنت اخي وهدا هوا القصد, مايبدو صعب لشخص واحد سيكون اسهل لعدة اشخاص, وهده النقطة هنا تفتح نقاش عميق اخر اود طرحه وسماع اجاباتكم.

السؤال: ان كان خالد وحده يحتاج لي 5 ساعات لحل بلوك ب 000 , ولو فرضنا انه انظم له 4 اشخاص (اصبحو 5 بخالد) وكلهم يجربون بنفس السرعة, كم سيحتاجو مجتمعين لحل البلوك؟ وهل يوجد اي عامل اخر باستتناء سرعة التجريب والحظ في تحديد المدة التي يحتاجونها؟

Like i've written. I do not pay electricity, which makes it easy for me.

So, your electity is free, and your default is ROI is short, but you want to extend it with extra expenses for immersion cooling? I am not being sarcastic, but why "immersion cooling"? air cooling works just fine, do you have a specific reason for why not stick to the default cooling?

That's a little bit over five months until i paid off the initial investment and after that no variable costs to produce the output.

5 months is somehow the best-case scenario, the hashrate is going to increase big time in the coming few months and if bitcoin price doesn't push a lot higher then all these numbers will not be met, please read this post of mine for further understanding of how these mining calculators are far from accurate.

I'm not sure what you would consider a good business model, but i'm right now learning at uni that, for example, investments in renewable energy that only break even after 7 to 9 years and turn in an interest of 4 to 5% interest rate over the whole runtime of the project are considered good investments.

A good investment as far as mining goes is super fast ROI, you should try to reduce the initial cost to overcome the difficulty increment and any potential price drop which leads to the overall extension of ROI, I don't know about renewable energy investment but I know that those solar panels have a warranty of 15-25 years and you are not competing against other people (there is enough sunlight for everyone), with mining, however, there is no guarantee that the used miner you buying is going to mine for 5 months straight, and if the price doesn't spike while difficulty does, the 5 months ROI could very well be 2 years.

Excuse me if I sound mean, but really, you are making a mistake thinking that just because you have free power you can beat the odds, I have free power myself, and I have lost many times, I lost a large amount of money, time and efforts into learning how to stay profitable when it comes to mining, it's nowhere close to the theory that says ( if you have free power, you are guaranteed to win).

With that being said, if this is just a learning process then I would invest in immersion cooling or anything else without doing the math, knowledge is power after all, but if this is a business plan, I would re-run the number twice.

Good luck.

Could you unplug chain 5 as I don't seem to like this part in the kernel log, only chip [29] and [57] are reporting hashrate, which isn't how it should be.

get RT hashrate from Chain[5]: (asic index start from 1-63)

Chain 6 doesn't look that healthy either, but chain 7 looks perfect, so I would start by removing chain 5, run the miner for 10 hours, see how it goes, if all good, then chain 5 is bad, if not - remove chain 6 as well and re-test.

I would also set a static ip address just to make sure, and reboot the router/switch.

3070  Local / العربية (Arabic) / Re: مسابقة Chipmixer 7 on: December 18, 2020, 03:35:41 PM
حسننا تكملة لمنشوري السابق, يوجد مشكلة في طريقة عمل هده المسابقة وهنا وجب التوقف وشرحها, وهي في الواقع جزء من مفهوم التعدين الحقيقي, لذلك يجب علينا ان نفهمها جميعا لتكون هده المسابقة مزيج من الفائدة الثقنية والقليل من الكسب.

المشكلة هنا انه يمكن لشخص ما مثل الاخ خالد ( علي سبيل المثال نظرا لانه اول من وجد حل) انا يقوم بالتعدين في المستقبل, او مايعرف ب pre mining يعني قبل ان ينشر حل البلوك رقم 2 بعد ايجاده يبدا فعليا في العمل على البلوك 3 وبمجرد وضع حل البلوك التاني يقوم بعدها بثواني بنشر حل البلوك ال 3 قبل حتى ان يبدا اي شخص في العمل عليه (طبعا انا لا اقول ان خالد سوف يعمل هدا ولكن هده احتماية نظرية قابلة للتطبيع حتى في البلوك تشين الحقيقي للبتكوين)

كيف يتم التغلب على هده المشكلة في العالم الحقيقي ؟

نظرا لان مكافاءة البلوك قيمتها عالية وتكلفتها عالية سوف يستعجل من يجد الحل لنشره لانه يعرف ضمنيا ان كل ثانية يتأخرها يعرض نفسه للخسارة حيث انه ان وجد شخص اخر حل للبلوك سوف يخسر البلوك الذي وجده الا لو تكمن ان يسبق كل المعدنين الاخرين ويكون البلوك تشين الاطلول ويفرض سلسلة البلوكات التي لديه, وهده النقاط قد ثم شرحها في موضوع الانفاق المزدوج.

هناك ايضا بعض الاشياء الاخرى المتغيرة في البلوك مثل مايعرف ب Merkel root فهيا عبارة عن hash الخاص بكل عمليات التحويلات الموجودة في البلوك يعني انه من الاستحالة تكرار هدا الهاش, ايضا وقت البلوك يدخل في الهاش وبعض العوامل الاخرى التي تجعل من هده المشكلة محلولة ضمنيا.

ولكن نظرا لطبيعة المسابقة هنا ولكي نكون عادلين يجب علي ان احرص على ان الجميع يبدؤن حل البلوك في نفس الوقت, لانه  بعدم فعل هدا سيكون للشخص الذي يرا منشور الحل الاسبقية, لذلك لنحل هده المشكلة سوق اقوم انا باضافة مدخل عشوائي بعد كل بلوك يعني بعد ان يقوم شخص بايجاد حل بلوك رقم 4, يجب على الجميع انتظار الاضافة مني التي ستكون في العادة 4-6 ساعات بعد منشور الحل ليتمكن الجميع تقريبا من البدء في نفس الوقت.

مثال , اخر بلوك لدينا هوا بلوك رقم 3 والذي قام بحله الاخ icy3 وهالش الخاص به هوا
 
Code:
00d720a088324db567a54d23e67746c25fd2f0b41051e3abf45e83944c91b9d9

الاضافة العشوائية لهدا البلوك هي

Code:
1235

مما يعني انه الان يجب حل هدا الهاش

Code:
00d720a088324db567a54d23e67746c25fd2f0b41051e3abf45e83944c91b9d91235

لاحظ اني قمت باضافة القيمة العشوائية 1235 على يسار الهاش, عندما يجد احد ما هاش البلوك القادم, سوق اقوم بضافة رقم عشوائي اخر عليه.

الصعوبة الحاية: 000 (هاش يبدا ب 000)

اتمنى ان تكون العملية مفهومة وواضحة.



فقط سؤال هل الهاش يجب ان يكون فيه عدد احرف او ارقام معين او فقط بشكل عشوائي والمهم هو الحصول على 3 أصفار كنتيجة؟

يجب ان يكون المدخل هوا هاش البلوك السابق + الرقم العشوائي الذي اضيفه انا, يعني تقوم بنسخ كامل النص مثل ماهوا مبين في الصورة


لاحظ ان هدا هاش البلوك الذي وجده الاخ ichy3 + الادخال العشوائي الذي وضعته انا وهوا 1235, وسوف يكون البلوك 4 على نفس النسق

أظن يجب تستخدم الرمز التعريفي للكتلة الي وجدها ميكي بالموضوع الرئيسي كما فعل خالد.
Code:
0aed8d5fab38911b26acbb5f5d47857c25268170c5de9bca5a0392c92cf007de

لا اخي Kavelj22 يجب ان يكون الادخل عبارة ان اخر بلوك تم ايجاده, بالاضافة الى القيمة العشوائية المضافة. سعيد جدا بمشاركتك.



النتيجة الحاليا:

khalid = 1
icy3 = 1

سوف اقوم بارسال الجوائز عند وصولنا لعدد لاباس به من البلوكات.

Also, X17 and X19 do not share same control board afaik.

It's stated other wise on thier website:

For the S19 series control board purchased from our official website, please upgrade to the correct and latest firmware as you will notice that the S19 control board has been pre-set with the S17 firmware. There are two methods to upgrade from S17 firmware to S19 firmware: Online upgrading and SD Card upgrading.

No matter which method you choose, the control board needs to be restarted after upgrading. Please wait for more than 30 seconds to turn on the OTP function. It can't be powered off during this process. Power failure will cause the OTP function to fail to turn on which also damage the control board.

Even though they sell them separately on their website, they do seem pretty similar if you ask me, but I don't trust Bitmain so ya, could be another mistake.

السلام عليكم ورحمة الله تعالى وبركاته

سنقوم في هده المسابقة باجراء عملية تعدين افتراضية, يعني اني سأقوم بصنع بلوك تشين "افتراضي" والشخص الذي يقوم بحل اللغز سوف يفوز بمكافاءة البلوك


مبدئيا لنتعرف على كيف يتم حل البلوك باختصار شديد, ولنسهل العملية سوف نفترض ان ال block header يحتوي فقط على

- هاش البلوك السابق
- ال nonce


nonce هي Number used once وهي "حل اللغز"

مايحدث هوا ان المعدنين يأخدون هاش اخر بلوك "حل اخر بلوك" ويقومو باستخراج hash digest باستخدام sha256 ويضيفو له nonce عشوائية ليحاولو الحصول على رقم اصفر من الصعوبة الحالية,لنقل ان هدف العصوبة الحالي = 00111 يعني ان النتيجة يجب ان تكون اصغر من ذلك الرقم,



مثال عملي:

هاش البلوك السابق 1
الهدف= رقم يبدا بصفر

الان يمكني ان اجرب تعدين هدا البلوك ,  بالدخول على هدا الموقع https://emn178.github.io/online-tools/sha256.html

وكتابة رقم 1 وثم اضف اليه ماشئت لكي تتحصل على هاش يبدا ب 0 وعدنها سأكون الفائز:

مثال على محاولة لي:



لاحظ معي هنا انني قمت بادخال هاش البلوك السابق هوا (1)
 وارقام وحروف عشوائية وهي (vofgh5g5df45) وهي ماتعرف ب nonce
 وتحصلت على هاش يبدا ب 0 وهوا (0aed8d5fab38911b26acbb5f5d47857c25268170c5de9bca5a0392c92cf007de) يعني اني قد حللت البلوك.


الان المسابقة:

باستخدام هاش بلوك 1 وبنفس المثال في الاعلى حاول الحصول على هاش يبدا ب عدد صفرين يعني 00 وباقي الارقام ليست مهمة, اول شخص يقوم بكتابة ال (nonce)التي تعطي نتيجة 00 او اكثر سيفوز بهدا البلوك وجائزته 10$



هدا حرفيا مايفعله المعدنين باختصار شديد, يكون لديهم رقم تابت ويقومو هم باضافة مدخلات عشوائية للحصول على رقم يبدا بعدد معين من الاصفار, كل المحاولات عشوائية والشخص التي يحاول اكثر لديه فرصة الفوز اسرع, وهدا تماما ماسوف تقومو انتم بفعله.





اتمنى تكون المسابقة واضحة, في حال يوجد اي استفسار لاتتردد بالسؤال




-يجب ان تكون رتبتك Member او اكثر
- لايمكنك تعدين بلوكين متتالين, يمكن حل بلوك جديد بعد ان يقوم عضو اخر بحل البلوك الذي يلي البلوك الذي قمت بحله.

Can i expect the same drop in power consumption with immersion cooling for ASICs like the S9?

Not really, well it's a tricky question, with immersion cooling you could save some power while on the other hand, you could actually use more power compared to air-cooling.

As far as the hash boards go, they don't care if they are in the water or anywhere else, whichever volts and frequency there is, the same power consumption will apply on all cooling methods, the only direct cut you get will come from the 2 fans on the S9, or the 4 fans on the 17 series, the average consumption of these fans is 5amps at 12v, assuming they run at 100% which is 60w each, so NFW figure of 50 seems perfect since it's unlikely that the fans will go full blast.

On the other hand, you are going to need to move the cooling liquid, if the power required by the pump and/or the radiator fan is < the total fans consumption then you win, vice versa, you lose, so if you use a pump that consumes 200w and use it to cool a single S9, then well, air-cooling wins, if the same pumps can run 10 S9s, then immersion cooling wins, I have no clue about which pumps are available and their power consumptions, I am simply showing you the proper way of doing the math.

You should also consider the initial cost for immersion cooling, it adds up to the gear cost and makes the business model look terrible.

Everything looks ok in the kernel, all three hash boards show 63 Asics (which is how it has to be), although chain 5 might be the cause, but too early to judge.

Sadly I just came back from weekend trip and I'm still having hashrate issues after leaving it on the entire time.

You forget to mention a very important thing. When you came back from your trip, was the miner run time equal to the time it was left to mine? in other words, did it reboot?

Yes you are right, I forgot to add the link, I also changed some of the settings to get a better view/representation, changed from linear to log, and limited the duration to only 3 years, the default chart is a mess.

I estimate gear at 45 watts now.

My guess is that the average is a bit more than that for now, I would take T17 as the average market gear for 2020, which puts us somewhere around 55 watts, what makes you think 45 watts is the average network efficiency?

But in the end, only 1 message is realy important: "solved and confirmed"

Exactly, I know it's hard for some people to understand ( i was trying to explain this to someone else IRL a few weeks ago), the chances of finding a block are independent of everything else including how close you were to solving a block, solving 5 blocks in a row doesn't increase the chances of solving the 6th block, just like how some people are mad because some blocks are being mined empty while their transactions are stuck, they think that empty block effects the confirmation time, the whole thing is completely random so why would anyone bother unless for the sake of some research or self-learning.

The idea is very simple, Profitblity = USD income per TH of hashrate, the worst it has ever been was on 18/10/2020 (exactly 2 months ago), a TH would gain only 0.063$, we are now kind of doing a lot better at 0.14$.

July 2019 it was about 0.5$ per TH, that will be 70k and not 30k, can you double-check the maths on your side?

The bestshare you see on your Cgminer is the share that had the highest difficulty value since your miner came online, target and difficulty represent the same thing in a different manner, the lower the difficulty the higher the target and vice versa.

Think about a scenario where you are blindfolded, I give you a box that has 1000 small pieces of paper, each has a number on it starting from 0 to 1000, I will tell you that if you pick any number that is smaller than 900 you will win the prize, in this case, the challenge will be very easy and thus the difficulty is very low while the target is very high.

On the other hand, if I want to increase the difficulty so that you can't win easily, I will say the number you pick has to be less than 5, so lowering the target increases the difficulty as it's more difficult to pick only (5,4,3,2,1 or 0) as opposed to picking any number from 900 to zero.

So the lowest share has the highest difficulty, your best share is the lowest one which is also the most difficulty and the one that was the closest to solving a block.
