نعم وصلة مباشرة من الباور الى الرايزر, يمكن استعمال كابل واحد لتشغيل 2 رايزر.



لا اعتقد انه يوجد باور سبلا واحد من شركة معروفة قادر على تشغيل 8 كروت ويحتوي على كابلات كافية بسعر مقبول فاسعارهم ستتجازو ال  300-400$, نصيحتي لك ان تبقي حجم rig عندك بما يتناسب مع باور سبلاي واحد مثل الذي تملكه الان وتجنب استعمال اكثر من باور سبلاي وايضا تجنب زيادة عدد الكروت على نفس ال rig , من وجهة نظري افضل عدد هوا 6 كروت, يعني باور سبلاي يكون 1000-1200 وات , 6 او 7 كحد اقصى  ومن تم تبدا في تجهيز rig اخر, سبب نصيحتي هدا لايتعلق فقط بالباور سبلاي والكابلات بل بالنظام وبرامج التعدين ومدى تبات النظام ككل, بناء على تجاربي وتجارب الاصدقاء في السابقي بمجرد تجاوز عدد 6 كروت يصبح النظام عرضة للمشاكل والكراشات و غيرها.

That makes sense, this also answers a part of the question by the way, thanks for pointing that out.


I am aware of this, I am also aware of that fact that things now are different, hence the reason why I said



Everyone has a different point of view, I can't speak for those who still mine on Cksolo and even went to as far as paying for the server, to me personally I have good memories with the pool, and I trust CK, he explained exactly what went wrong and he made sure he corrected it, and what's more important than this are MANNERS, something some people lack, CK has been respectful and nice to most of us, I would go to the extent of paying solely for the server and point a good portion of my hash rate to Cksolo, this is more of a culture thing I suppose, I am sure many people don't mind dealing with people who show no manners, and all that matters to them is the business itself, to me, respect and attitude matter, will I lose a block on Cksolo pool? no problem, I still wouldn't mine to a pool whose owner calls someone who is probably at the age of their father "stupid".


You too.

I don't know how you arrived at the conclusion that I think you were attacking me. I never said that. you misunderstood my previous post, so did NFW, surprisingly and ironically only Kano understood it, so I had to explain myself, I am not attacking anybody either, all good. 

The rest of my reply is general information for everyone, not pointed directly to you.

Thanks.

I never said i had no way to tell, I said I don't care, there is a difference.

When I mine solo I set awesomeminer to send me 2 different emails when a block is found but I don't do that when I mine to a pool (mostly fpps/pps+) I don't bother, most people don't I suppose, and that was my concern when NotFuzzyWarm said that pool never lost a block, anyway the answer is now clear, as for pps pools, I am pretty sure they operate on the right server and with the proper code, highly unlikely that nowadays pps pools lose a block for any reason but "bad luck", despite the fees running a pool on fpps has a lot of risks, losing blocks is something they would never want happen.

Also, one thing to keep in mind that losing a block due to bad luck and not technical deficiencies has to do how many blocks a pool is subject to find in the first place, Kano pool hardly finds any blocks on the grand scheme of things, I even saw him brag about not mining an empty block in my empty blocks analysis topic , I didn't want to comment on his post in that section to not trigger him there and make members of that section suffer reading his disrespectful replies, it's enough that members of mining board are suffering.  

what Kano seems to don't know or ignore is that the probability of him hitting an orphan/empty block is directly related to his chances of hitting a block in the first place, given the tiny hashrate he has compared to the large pools it makes sense why he is unlikely to hit an empty or orphan block, of course, with all technical aspects like having the right code, server, and connection being equal.

Think about it this way, what is the probability of a coin landing on its side when you toss it 1 time vs 1000 time?, Kano said the time to verify and construct a block is less than 2 seconds, so applying "cumulative distribution function aka CDF of the exponential distribution" on his numbers we get:

exp(−1/60)−exp(−2/60) = 0.016 or 1.6%, all miners combined are expected to hit a block between 1 and 2 seconds at a probability of 1.6%, what is Kano's hashrate % compared to the whole network?

90,000,000TH vs 10,241THs ? 0.011%, the chances of collision with another pool and hitting an empty block are close to 0, so not finding orphan or empty blocks is fairly based on his tiny little share of the total network hashrate.

To be fair, of course, this doesn't negate that fact his pool's infrastructure is good enough to maintain his tiny 0.011% chances at 100% whereby he doesn't lose the blocks he hardly finds, so that's good overall, but it doesn't make his pool better than those pools that lose blocks due to "bad luck", and regardless of anything I highly doubt he runs a better code or owns a better server than those multi-billion $ pools, but it's good to have a few small pools around, in fact, if he wasn't such a jerk - I would point at least 2-3ph to his pool, but with his attitude, not a chance in hell.

This one line answers the question, the rest of the wall of text was nothing but a waste of the forum resources and more proof of your terrible attitude for everyone else to see.

@nNotFuzzyWarm , @Stryfe

Both replies didn't answer my question, it is safe to assume that most people mine on pps pools (given the hashrate of those large pools), people pay 4% in fees to mine on Viabtc, why would they waste time or even bother if the pool loses a block?it is the pool responsablity to ensure blocks go through.

The point i was making is that many non-solo pools could be losing a ton of blocks, but because miners don't care those blocks go unoticed, now based on kano's answer (assuming he is telling the truth) miners will know if a block was stale or rejected, and without providing such features, one can't say (i never lost a block) because they could very well lose blocks and nobody would notice.

Hope i made myself clear, Thanks both.

First thing you should post the kernel log, the complete kernel log while chain 0 is plugged in, use the code function to paste the kernel log like so


A wild guess based on what I already know, you have one or more heatsinks/chips with bad soldering which has lost contact to the board, it causing a problem in the electricity flow within the board and stopping the temp sensors from working, the control board "thinks" all 4 temp sensors are bad so it does not allow the chain to mine for safety purposes.

What to do and how to fix it is a different topic, i will guide you through it once I see the kernel log.

اعتقد ان الاعضاء المذكور اسمائهم يعتبر نشاطهم متوسط في القسم العربي ( بما فيهم انا طبعا ) يوجد الكثير من الاعضاء الاخرين النشطين او اكثر نشاطا ولكن نظرا لاننا في موسم العيد فمستوى النشاط منخفض.

طبعا كم المنشورات هنا نسبيا ومقارنة بغيره من الاماكن يعتبر صغير، فنحن نركز على الجودة وليس الكم، وايضا لان ترقية الحسابات لا تعتمد على عدد المنشورات بل جودتها فكثير من spam يختفي تلقائيا.

على العموم شكرا على كلامك الطيب.. ومرحب بيك في المنتدى.

You have just explained 'scientifically' what I have been trying to tell everyone for months, dude we need more people like you around.

So, since the soldering melts at fairly low temp, will under-clocling these miners give any improvement in the lifespan of that tin before chips start falling? Or should someone just overclock the heck out of them because they will melt either way? Or leave them at stock?

Also what soldering flux do you suggest to use? A product link from Amazon will be great.

بما ان ال riser التي تسخدمها تدعم 6 pin فالافضل ان تستخدم وصلة 6 pin مثل هدي

https://www.amazon.com/gp/aw/d/B072MYWQ8D/ref=sspa_mw_detail_0?ie=UTF8&psc=1

اما بخصوص الطاقة فمن المستحيل ان تكون هده الارقام حقيقية، البرنامج يقوم بحسابات تقدرية والطريقة الصحيحة هي قياس الامبير باستخدام multimeter او killawat.

ال 7 كروت التي تملكها تستخدم مالا يقل عن 850 وات على القورتيم ال ethash..

باضافة كرت اخر ستصبح تقارب ال 1000-970 وات.. يجب عليك متابعة اداء الباور سبلاي..لمس الكيبلات باستمرار لتفقد الحرارة وغيرها من الاحتياطات.

استخدم الموبايل الان..البحت عن رابط الكيبل لن يكون سهل ولكن ساقوم بذلك غدا..السؤال المهم ان كان الباور سبلاي لا يحتوي اكثر من 5 مداخل6 بن..كيف تقوم بتوصيل 7 كروت شاشة؟
انسى الرايزر اخبرني كيف تغدي الكروت بالكهرباء.

بخصوص التعريف نعم يجب عليك تنزيل الدرايفر الجديد يعني اصدار 17 ومابعده لتتمكن من تشغيل اكتر من 8 كروت.

على العموم لا انصح باكتر من 6 كروت لكل rig كحد اقصى....

ومن تم ان الباور سبلاي لن يستحمل كل هده الاحمال...
1200*0.8 = 960w
960/6  = 160w

6 كروت amd 570-580 هي العدد الاقصى الذي يتحمله الباور سبلاي لتشغيل امن.

هل قراءت الموضوع الذي ادرجه الاخ اوميجا؟ الموضوع مليء بالاثباتات, هدا اولا, اما تانيا, لا يوجد اي موضوع ضدهم بعدم الدفع لحملات التوقيع, لذلك انا اصدق انهم دفعو لك بدون حتى ان تضع دليل على ذلك, المشكلة تكمن في كون ان اكثر من عضو قدم الادلة الكافية التي تتبت بدون شك ان منصة يوبت منصة نصابة, وسمعتها في هدا المنتدى سيئة جدا جدا, لذلك بانخراطك في حملات توقيع تتبعهم قد تعرض نفسك للحصول على تقيم سلبي نظرا لانك تدعم النصب بطريقة او باخرى, وهدا قد يؤتر ايضا على فرصتك في الدخول في حملات توقيع اخرى في المستقبل.

انا اشارك الاخ اوميقا في توصيته بعدم الانخراط في هدا التوقيع على المنتدى, وطبعا كل شخص حر في خيارته فقوانين المنتدى لاتمنع النصب اصلا!, وعلى العموم شكرا لك على مشاركتك الطيبة واتمنى ان تزودنا بمزيد من المعلومات حول حملات اخرى لكي يستفيد الاعضاء.

Maybe bad wordings on my side, i edited that, i obviously don't mean the board is useless and we should delete it, i am saying it has been allocated the resources it deserves and it is not worthy of getting more mods to moderate it, larger boards with more importance are moderated by a single moderator.

Also when i say reputation that should not be mistaken with "scam accusation", anyhow, that is just my opinion, and the decision will obviously be theymo's.

That will be a waste of resources given that the board of reputation adds only a limited value to the forum and it has become more of a place of personal attacks between 5-10 members repeating the same thing against one another for years, one of the reasons why we have self-moderated topics is the fact that the forum will never have enough resources to babysit every topic.

فمت بتخطيط وصلة molex في احد الصور التي ارفقها انت



شكل الكابل من الباور سبلاي يكون هكدا



وصلة ال 4 pin طبعا.

طبعا انا لم افهم طريقة تصويلك لان الشرح غير واضح والصور ايضا ليست واضحة ولكن بالمجمل دائما حاول ان تبتعد عن وصلات sata بقدر الامكان وقم باستبدابلها بوصلة molex كل ما اكمنك, لان مولكس تععطي 132 وات بينما وصلة ساتا 45 وات فقط تقريبا.

How can you be so sure? "Absence of evidence is not evidence of absence," no?

The reason why people were aware of ckpool losing the 10th of May block for an example was the fact that the miner was mining solo, in other words, I own a lot of mining gears, I only care about the shares of 2-3 of them that are mining solo, the rest of them could be finding blocks and pool is losing some of them and I am totally unaware of it, I don't pretend to know more than you do about this subject, not making any claims, I am simply asking you a question because I can't ask Kano due to his obvious filthy attitude.  


I also think his attitude has a lot to do with this, I rather mine to a pool whose operator would respond to me with total respect and patience regardless of the risk, rather than mining on a "better" pool owned by someone who is disrespectful., but that is just me.

The problem is, inflation is relevant to the host and it's a risk for him but not to miners, in other words, if for whatever reason gas prices increase and say it now cost him 7 cents per kWh while he is bound by a bunch of hosting contracts where he is obliged to offer 10MW worth of power for 5c per kWh which he got paid for upfront, and his cost is 4 cents so he makes 1 cent of revenue, say 0.5 cents per kWh of net profit, and then out of a sudden it starts to cost him 7 cents, so he loses 2 cents per Kwh on 10MW that is a ton of money to be losing.

I have noway to confirm this claim, but it doesn't matter, 100%  or 10% doesn't matter, you are still making money of Bitmain mining gears, and if you are honest about these numbers, why don't you just block bitmain gears?


To prove that you are not a hypocrite because you said:



No proof of finding blocks is the only reason you block them, you don't care about cgminer license as long as you get to make money, you curse bitmain but you don't mind thier gears mining to your pool because they make $$$.


Stop your hypocrite nonsense, stop quoting me, and i won't be commenting on any of your future posts.

Regards.

I know very well what violets the cgminer license, I know and you know that Btmian does violate the license, you said that your self, yet you have no issue with earning money by your pool which makes nearly 100% of its profit of firmware that violates this very license, hypocrisy?

@kano

So does Bitmain firmware, and so does your mining pool by allowing firmware made by Bitmain and Microbt which refuse to release the source code, there is no difference between all of these firmware versions as far as Cgminer license is concerned.

On a side note, refrain from posting twice in a row as it's against the forum rules, and your second post will be deleted or merged with the first one in the best-case scenario, and then you will likely accuse the mods of having a biased approach towards your posts which break the from rules.  

A message was signed from 145 address which CW claimed to have access to, user @Zectro on twitter was the first to report it on the twitter platform, looks like he got it from the BSV subreddit post by u/bit_LOL

I randomly verified a few addresses and all of these address seem to be correct.

The next step was to get the list of addresses that CW claimed to have, I managed to find it this article where they had a link to the PDF file which contains all addresses submitted to the court by Craig Wright, I randomly checked a few addresses and they all match.

So it looks like everything about this is authentic, by randomly checking the time of the coinbase transactions on some of these address, they revolve around 30,000 blocks height, this person was mining bitcoin around  Nov-Dec 2009.
