Op, i would chose vnish (awesome miner) as that lets you use the monitoring software without extra cost, since you will be overclocking the miners, you need something like that.

Also, be careful with the PSU rating, some profiles on those custom firmware require a custom PSU, the solder on those gears is bad so make sure the fluid you use is of a very high quality.

Like willi i am also interested.

حسب فهمي للقرار انه لم يكمن يشمل استثمار المواطنين الاوروبين في الخارج, مما يعني انه لم يكن ليغير شي بخصوص هده النقطة بل كان فقط سيوقف عمليات تعدين البتكوين داخل الاراضي الاوروبية والتي تكاد تكون معدومة من الاساس, والقلة المتبقية سوق تغادر مجبرة بدون اي قانون نظرا لان السوق الامريكي افضل بكثير, فمثلا تتحصل بعض شركات التعدين هناك على سعر تكلفة للكيلو وات تصل الى 2.5 سنت, هدا السعر لاتملكه حتى الشركات المنتجة للكهرباء في اي دولة في اوروبا, يعني انتهاء التعدين هناك هوا شبه شي اكيد ولكنه مسئلة وقت فقط.

Yup, those U.S large players don't play around, while everyone is busy with all the shit going on in the world they are adding exa hashes worth of hashrate faster than we are adding tera hashes, it looks like 300EH this year isn't too far fetched, I can't imagine what is going to happen if BTC price takes another huge hit and drop to 20k or so, what will these companies say to their investors? I assume the money they are spending isn't theirs, so how is it going to be?

This will be a risky move taken for nothing, the exchange can just freeze your account and claim that you were doing money laundering shit, even if you were to prove that you got those 6.xx bitcoins sent to you from ckpool, they can still claim that you rented some hashrate using stolen money or anything like that, this is just 1 out of the so many excuses an exchange can come up with once you make a sudden deposit of about a quarter-million dollars.


Trust wallet is a million times better than an online exchange, although, IIRC, only the IOS version is open-source, so if that matters to you, make sure you read about it, if you want to be more careful about which wallet to use, check the wallet software section and pick one.

Maybe there are other ints in the code that have to signed and they wanted to avoid mixing both signed and unsigned ints in the same function as that would be slower than using either one on it's own.

Anyways, one of the folks who wrote that code is still somehow active in here, he 'might' be able to answer your question via PM if you really are eager to know.

But why? What is the need for a signed integer in this code? It is not like val can be negative in the first place, I know some operations are performed faster with signed ints in c but with todays hardware the difference is likely nothing, in fact, a few operations like division will be faster with unsigned ints.

Maybe they benched marked the code back then and so happened signed was a bit faster, which might have changed with today's hardware.

That is just the number of combinations of bits you can have in 8 bits, so if you start with 0000-0000 all the way without duplicates, you should have a total of 256 (including 0) different sets.

That is called an unsigned 8 bit which can be represented by 2^8 - 1 = 255

The value in the code you posted is a signed integer and one bit will be used as a flag so now you have xxxx-xxx1 which can be represented as 2^7 - 1 = 127, anything above 127 will be 2 bytes and 2 bytes of unsigned int should be (2^15)-1 = -+32767 but the code says 16511 is the limit which means according to this 1 bit is used to determine the number of extra bytes which is represented in 0 in the above ( xxxx-xx10-xxxx-xxxx) and that will give you 2^14 +127 = 16511, next will be 3 bytes or  2^21 + 16511 = 2113663 and so on.

Edited: added more details.

You are confusing terms here, heatsink is only used for cooling, the miner can run without any heatsink attached (well, not for a very long time, but you get the point!), a missing chip on the other hand will stop the miner from running, but according to your image, it seems that the 63 chips are there, also judging by the temps, it doesn't seem like there is any missing heatsink.

My guess is that you are counting the empty slots or the heatsink at the backside of the board, the S9 has a few "missing" heatsinks at the back by default (IIRC it's a total of 12 missing) and the front side has 63 heatsinks.

So -0.35% after seeing -4% somewhere in the middle of the last epoch, despite the war and gas prices difficulty managed to stay almost, we know that there is a good possibility that a large number of mining farms in Ukrian had to shut down, but it seems that the large U.S players compensated with the gears they keep bringing online.

It must have slipped their minds, why not send them an email?

اعتقد انه يقصد ذلك فعلا, وهدا ماقد اشرت اليه في منشوري السابق, ولكن اعتقد ان الاخ GxSTxV "يتوقع" ان شخص اخر قام بتحويل العملات الاخرى وهدا مالا يمكن معرفته لانه يمكن ان يكون نفس النصاب الذي نشر تلك المفاتيح هوا من قام بتحويل العملات.

نعم بكل تأكيد, البوت عبارة عن برنامج مثل المحفظة يقوم بارسال الاثيريوم فور وصولها, يمكن للضحية او نصاب اخر برمجة نفس الكود وسيكون الرابح بينهم هوا الشخص الذي يتملك القدر الاكبر من الخبرة حيت ان تحديد ال gas سيكون مهم, ايضا سرعة عمل الكود وعامل التوقيت والحظ سيكون له دور كبير في هده المسئلة, فيمكن ان يتم تحويل اموال كل ضحية لاحد النصابين وليس كلها من نصيب النصاب الاول.

If you want to see each miner on it's own just follow what phill wrote, ckpool will still show the best share of all miners at the top of the page.

As far as duplicate work goes, do not even worry about it, it won't happen no matter how you configure your miners.

بالنسبة للتعدين في اوروبا فهو شبه غير موجود في الاساس نظرا للتكلفة العالية للكهرباء, لا اعتقد انه دول الاتحاد الاوروبي مجتعمة تمتلك اكتر من 10% الهاش ريت الاجمالي الموجود في العالم, حظر التعدين في دولة مثل امريكيا الان او الصين سابقا يمكن ان يكون له تأثير اما اوروبا فهي ببساطة خارج المعادلة.

اكبر دول للتعدين في اوروبا هي ايرلندا التي تمتلك حوالي 4.6% يليها المانية ب 4.4%, وباقي الدول لا تمتلك الا القليل.

مصدر النسب هوا دراسة جامعة كامبردج في هدا الرابط https://ccaf.io/cbeci/mining_map

طبعا اخر تحديث للدراسة يعتبر قديم نسبيا, وبناء على اطلاعي المستمر على عمليات التعدين اتوقع ان هده النسب انخفضت الى النص تقريبا.

If you don't want to do the manual calculation as phill did, you can always use something like https://whattomine.com/miners, just make sure you enter your power rate in the top-right corner and hit enter, and then search for the miner you want to check and the results will be fairly accurate based on current price and difficulty.

**keep in mind the power cost must be entered in dollars not cents, so if you pay 5 cents per kWh you must divide it by 100 and type 0.05.

It depends on how you set them up, if they use the same exact worker name they will show as one miner with all the hashrate combined, if you change the worker name after the (dot) they will be separated in the pool details but still workers under the same wallet address will show a combined total hash rate at the top of the status page.

All that these fine gentlemen said is true, it's simple physics which nobody can argue about, but (a big one) the effect of removing one hash board isn't exactly that huge, the impact on temps isn't all that bad, the two boards will run cooler if a 3rd dead hashboard is there (better airflow + the heatsinks on the head board will absorb some of the heat from the other working hash boards), but the two boards will still run cool enough regardless, they do get less airflow compared to a full miner, but the heat that was generated by the 3rd board is no longer there which helps to balance things out.

I tried that on tens of S9s, the effect on temps is little to nothing, nothing major that had me modify anything, so really, the only way to know would be to test your miner, do a before and after test, I highly doubt the temps will vary widely, but just to be safe.

الرسوم منخفضة منذ فترة, العامل الرئيسي في اعتقادي هوا السوق الهابط الذي نمر به, الرسوم ترتفع في حال كان السوق صاعد وكان هناك العديد من العملات الجديدة و ال ICOs او IDOs والكتير من البيع والشراء على Uniswap وغيرها من المنصات, وايضا ترتفع في بادية انهيار الاسعار حيث يهرع الكثيرون لبيع عملاتهم ويدفعون مبالغ ضخمة للخروج حيت تصل الرسوم في تلك الاوقات الى 500 Gwei واكثر, اما في فترات "الركود" فمن الطبيعي ان تكون الرسوم مابين 10 الى 15 Gwei.

افضل الاوقات لعمل اي تحويل يكون حوالي الفجر بتوقيت قرينيتش, وافضل ايام الاسبوع يكون يوم السبت, في حال الارسال كان غير مرتبط بوقت زمني مثلا (تحويل مباشر خارج نطاق المنصات للامركزية) يمكن وضع 10 Gwei كرسوم وسوف يتم تأكيدها في فترات الليل المتأخرة بنسبة كبيرة جدا جدا, في حال كنت تنوي شراء او بيع والتحويل يجب ان يتم بسرعة استقيظ في فترة الفجر ودع المحفظة تحدد قيمة الرسوم وعلى الاغلب ستدفع اقل من 15 Gwei.

لا اعتقد ان الخدعة تتم ,عن طريق العقود الذكية, حيث ان الضحية سيرسل عملة ايثيريوم على layer1 وهنا لايوجد اي امكانية لبرمجة اي شي داخل اي عقد, المحفظة يكون رصيدها من الايثيريوم صفر ولكي يتمكن الضحية من نقل العملات الاخرى التي وضعها النصاب الضحية يرسل عملة ايثيريوم لاستخدامها ك gas والبوت يكون مبرمج باي لغة برمجة وتكون وضيفته نقل عملة الاثيريوم نفسها لعنوان اخر يمتلكه النصاب فور وصول المبلغ, حيت يقوم البوت او الكود بعمل سكان على كل التحويلات الواردة في كل تانية او جزء من التانية ويقوم بتحويلها مباشرة قبل ان يتمكن اي من الضحاية من استخدام ذلك المبلغ ك gas لنقل العملة الاخرى.

طبعا يمكن ان يستعمل النصاب عملة لاقيمة لها او عملة قام هوا بانشاءها ويكون في عقد العملة قاعدة شرطية معينة تمنع ارسال العملة الى اي عنوان الى عنوانه يملكه النصاب نفسه, ولكن هده الحيلة من الصعب ان تنجح لان معظم الضحاية سوف يركزون على نوع العملة, وفي العادة تكون عملات مشهورة ومعروفة وذات قيمة, احد المحافظ التي اذكرها كانت تحتوي على تقريبا حوالي 10 الاف دولار usdt وكان الضحاية يرسلون قيم صغيرة من الايثيريوم لاخراج ال usdt ولكن كانت العملات المرسلة تتحول مباشرة الى عنوان اخر ولم تتحرك ال usdt من مكانها.

 

I am not sure why you think I have anything against you or your company, you were probably the first company I listed, I merited your previous post for the efforts and to help you rank up to bypass the post limit.

The goal of this topic was and still is to connect people with dead miners to people who fix them, but that does not mean I should not talk about some companies that have 6 months delay, but again, if you are not happy reading the negative reviews here, either improve your performance or create your own topic.
