"boards have serial numbers and will not mix and match from different cases" that i thought that was the case lol  Shocked Grin

 guess i have to trial and error to figure out now how to put everything together and what board goes to what miner...

 learning process all the way!!!

Hey!!, don't even worry about that, only the stock firmware cares about that, vnish doesn't read the voltage stored in the EEPROM and thus you can mix and match boards all you want, I tend to believe all other custom firmware do the same, I just don't have a good experience with them, but I know vnish works.

Obviously, since you will need to disable the fans and overclock the miner, you won't be using the stock firmware either way.

Also, you have got a loose heatsink shown in this image, you have to solder it back on, I highly doubt you can get away with no-heatsink even with Immersion cooling.

Thanks for keeping this topic updated.

Just now finding her telegram, couldve used this sooner. Feels sketchy but if people here have really used them, then what can i say.

Prices also seem real good??

In this industry you should assume by default that all resellers are scammers, it is the right thing to do.

With that said, Grace and her employee bella are among the minority of legit sellers.

As for the prices, you can find cheaper offers if you buy directly from farm owners or some other resellers, but you will need to depend on your luck that the gears you order actually work, grace charges a bit more but she tests everything before shipping, so it is up to you if you want to risk a whole miner just to save some money.

Mikey Would like to know more about vnish, was thinking to overclock using asic.to
my plan is to take them all apart and wash everything really good with iso propylic alcohol before put them in the liquid

Asic.to is vnish too, see vnish has many distributions, they all are the same, the difference is what you get from using one of the different versions, asic.to has a great own support for the firmware, AwesomeMiner lets you pay the monitoring fees using those built-in firmware fees so you don't have to spend more on monitoring license.

So all in all, it all depends on what would you need the most out of these "extra features", but Vnish as a whole is a lot better than mskminer IMO.

as for uploading images, use something like https://imgur.com/ and post the link here.
1765  Bitcoin / Hardware / Re: Imersion cooling project on: March 21, 2022, 10:43:40 PM
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.

و لكن يمكن لشعوب هذه الدول الإستثمار في مجال التعدين في بلدان خارج الإتحاد، لهذا يبقى قرار التصويت ضد منع التعدين إيجابي للمستثمرين مما يشجع على إنضمام أفراد و شركات لينتج عنه التبني الجماعي.

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.

ugly. +6%

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?

is it okay if i use exchange wallet as user? i mean is there any posibilities if i hit a block, the reward will gone if the exchange forbid mining reward?
thank you...

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.

how about online wallet for example trust wallet?

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.
1769  Bitcoin / Mining software (miners) / Re: cgminer - blockchain height in coinbase transaction on: March 20, 2022, 03:13:29 PM
Good question, I was thinking exactly the same. After a quick search through the Bitcoin core code, I couldn't find any reference of the height defined as signed integer either.

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.
1770  Bitcoin / Mining software (miners) / Re: cgminer - blockchain height in coinbase transaction on: March 20, 2022, 10:48:53 AM
Indeed it's a signed integer Roll Eyes Ofc, it's one bit less then...

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.

1771  Bitcoin / Mining software (miners) / Re: cgminer - blockchain height in coinbase transaction on: March 19, 2022, 10:08:22 PM
Could somebody please explain why the limits for the byte length have always been set way lower than what the little-endian encoding would allow?
E.g. length 1 would allow for 255

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.

Quote
The number of trailing zero bits in the first byte indicates how many subsequent bytes there are. This allows the number of bytes in an encoded integer to be efficiently determined with a single instruction (e.g., BSF or TZCNT) on most modern processors.

1772  Bitcoin / Hardware / Re: Just purchased an S9 Miner off Ebay and it has one heatsink missing? Still Mines on: March 19, 2022, 09:09:44 PM
Board 8 has a heatsink totally missing YET it is still hashing ok??

How can this be? I presumed chips were all in series, so if one goes down the rest/all do??

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.

لم أفهم تحليلك يا صديقي. هل تقصد أنه من الممكن حقا الالتفاف على طريقة التحيل هذه و النجاح بارسال المبلغ الذي بالعنوان الى عنوان اخر ليس خاصا بالنصابين؟

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.

1776  Local / العربية (Arabic) / Re: طريقة ذكية للنصب [تحذير] on: March 17, 2022, 06:31:31 PM
بما أن الضحية سيكون لديه المفتاح الخاص للعنوان حتى يطمع بارسال التوكن الى عنوانه الخاص، هل من الممكن تقنيا أن يقوم ببرمجة بوت جديد قادر على تعطيل عمل البوت الخاص بالمتحيل أو بوت اخر باعدادات تمكنه من استخراج التوكن؟

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.

Many thanks for taking time to reply, I just have my BTC address in the worker field in all my Miners, when I query the stats you are right it show the total hash rate of all of them and the total of workers. But when I look at each miner separately They have a different bestshare which made me thinks they are working independently for the same worker but this could duplicate the work and waste hash power. Angry

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.
1778  Local / العربية (Arabic) / Re: الاتحاد الأروبي و حظر التعدين on: March 17, 2022, 12:45:02 AM
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.

How u do the math sir

I am new ... when I check online
 It say 50 cents to $1.5 a day after electricity

Can u explain please I might be calculating it wrong

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.

Hi Guys when I point 3 workers to Ckpool do they hash as one or separate?

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.
