OP are you asking a question or stating a fact? If you managed to run S15 hash boards on a V9 control board then that is nuts!! If you are asking if you could do that i'd bet on a no.

What do you mean by power control output? Can you post some pictures?

Only the last couple weeks alone i read a handful of people asking for it, in many none "1st class" countries internet is very expensive and limited, also some farms are hosted in remote places and rely on limited cellular data, a simple package for newbies would be really really great IMO.

Would you be so kind and make a newbie guide for how to set the mining proxy? I see a good number of people having issues with limited bandwidth and using a proxy is probably their best option, there is a lack of documentation online in regards to that subject, or at least I have not found any article that explains the steps to the average joe, so if you could do that it will be huge and very highly appreciated.

What are the default settings? your gear on cksolo pool shows


Looks like 4-5th is the actual hashrate showing on your miner's status page, which is still strange, S9k running on E-LPM should mine at 8-9th not 4-5th, or at least this is what the other S9 models do when you use Enhanced LPM, when you activate only LPM it means enabling asicboost which doesn't affect the hashrate but gives you about 200-250w drop in power consumption, but the K version seem to have pretty different settings.

Phil, aren't we officially difficulty prediction experts?  

Jokes aside, diff.cryptothis is undergoing some changes, a nice copy to clipboard function, and seems like dark-mode is in the making.

So at current prices and difficulty, a lot of S9s are profitable, many S19s / M30s came online, I am not surprised seeing 88 blocks ahead in under 500 blocks, looks like the jump in difficulty for this epoch will be big, maybe big enough to wipe the -9% we had.

Some of us here take the time and effort to warn others about a scammy firmware/person and you just ignore all of that, and then a few weeks later you will come back to complain about it and look for solutions, don't be lazy, read the comments!! this firmware is SCAM, I have even left them negative feedback fairly visible on their profile.



STAY AWAY FROM THEM!!

There is really no way to tell unless you try, based on my experience most old S9 boards mix together well, this is specifically for S9/S9j/S9i, the newer models like the S9k is a whole different story, you can't mix different boards even from the same exact batch, there is SN on each hash board, the once I have are either labeled with an SN that starts with 1,2,3, so 1 will only work with 1 and so on, mind you that those were ordered and delivered on the same exact day, but for whatever stupid reason, Bitmain firmware won't allow me to run them on the same control board, so I ended up with a few miners that have a single hash board on them, which I can't mix.

Keep in mind that it's very unlikely that mixing boards will cause any damage, so you will lose nothing, you flash whatever firmware you want, and test it if it works - it works, if not - remove the incompatible hash board.

It is, everything about the S9k is bizarre.


Maybe it's mining the current block -1  


This is way cooler than immersion cooling, never seen a miner that run at temps this low, if you set 100% fans it will surely drop below 30c for chip temp, but I am not sure that will be good for the miner, anyway, 200w for 2th wouldn't be so great, 200/2.2= 90w/th, it would be cool if it was 150w or 70w per th, I doubt that anyways, but please post the results when you get them.

Those are great advice, however, none of them actually answers his question, regardless of using a different quieter fan, he would still want to set a fixed a static speed on them, OP a simple search would have answered your question, I wrote a complete yet simple guide on how to achieve fixed fan speed on almost all Antminer models.


Using the same tricks to show the fan settings, you get to see the LPM option on S9k and S9e, I have not tested it, but it does show, please follow the same guide to show the hidden features.

Just for the record, I paid $263.00 for those crappy S9ks, they weren't at $60 like now, so really nearly $300 for that gear doesn't give bitmain the excuse to send them with fallen chips and heatsinks, in fact, the QS measure should be same on all gears, cheap gears cost less to manufacture, which is why they can afford to sell them for so cheap, but QS is a different story, around the same period of time I bought S9js for $276, and they are a trillion times better, those S9js were probably stored from previous years batches, and given that all the new gears S9 or not have the same issue of chips/heatsinks falling, it shows that something went wrong in their QS department, something which all the S19s buyers should keep in mind, although Jihan Wu promised that the S19s will be robust after he admitted the 17 series were crappy, he, of course, puts the blame on Micree Zhan.

Ironically I tend to believe Jihan this time, not because I think he is honest by any means, but the S19s are their last chance, so it's very likely that everything about S19 is going to be a lot better in terms of quality, I am just not willing to take the risk until it's confirmed.

True, the system doesn't have to run 24/7, maybe just during the day and a few hours at night, remember you need to focus on winter's numbers since this is more like a winter space heater, so say 5 hours per day from solar, maybe add 3*100ah 12 volts battery, I guess they cost about $400 and can give you 6 hours of 300 watts, so you are getting 11 hours of free mining a day for about 4-5 years.

So you looking at about 1k for the whole setup including the miner, if you run it around the winter only, maybe 6 months, this gives you about 8-10 years of heat and a ticket in the bitcoin block race.

Looking forward to more details on your project.

I believe it has little to do with the outside temp when the miner is not running, also bad handling of packages doesn't seem to be the reason why those chips on my S9ks fell, I had a lot of them shipped, some for me and a lot for clients, they all arrived at the same time with the same environmental conditions, a few had heatsinks fall right out of the box, some did mine for a few days, some for a few weeks, some are still good to this point but overall terrible, so my guess is that alongside with the terrible quality of their solder paste, those S9ks don't go through a quality process, so depending heavily on your luck, you might receive a bricked gear as I did.

معظم اعضاء المنتدى متعصبين للبتكوين بصراحة, في الواقع بعضهم قد يترك لك تقيم سلبي في حال تشجيعك لعملات اخرى  , وبالرغم من اني مقتنع ان البتكوين افضل عملة من حية الامان والاستتمار الا اني اشك في قدرتها على التأقلم لتكون عملة قابلة لاستعياب جميع التحويلات المالية في حال ان وصلنا لنقطة انهيار الانظمة المالية وانظمة الدفع الحالية, وهدا بدوره سيؤدي الى ظهور عملات اخرى تتمتع بقدر مناسب من الحماية والسرعة, حتى وبعد مرور عشرة سنوات على الكريبتو لا يمكن الجزم بأن البتكوين ستكون دائما في الصدارة, نحن الان في سباق مع الزمن وكل العملات تحاول اعطاء افضل مالديها لتكون جاهزة عندما يحين الوقت لاستعمالها, البتكوين لديها افضلية الاسبقية وفي الواقع هي من خاض اصعب واهم اختبار وهوا الانتقال من العدم الى الوجود, البتكوين لديها كل الفضل في ظهور تلك العملات الاخرى وحتى وان فقدت ترتيبها في يوم من الايام.

More than a single panel for 300watts? when did you buy those? the lowest I see nowadays where I live is 300w per panel, up to 500w, running the space heater version of S9 might do, let's say it needs 300wh so that's 7200w per day, depending on where you live, say you get 5 hours of sunlight ,so all you need from the backup batteries would be  5700w per day, in batteries' language that's more like 5700*2 = 11400w since you can't really discharge a battery with more than 50% DOD, say your system is 12v so that will be 950ampH batteries, well, worse than I thought . I think 950ah will cost you about 1k,  say with you get an average quality battery with 1500 cycles at 50% dod, you are looking at about 4 years of running that S9 on batteries and solar alone, provided of course you have enough solar to charge the batteries to 100% in those 4-5 hours of sunlight.

I remember this story, you told me about it once, still interesting every time I read it, so free power in "great" America, let alone other countries, where I live we have access to free or nearly free power in most places, I know a few other countries, I know a country where people would set farms in the middle of nowhere, bribe someone in the power company because it's owned by the government, they hook up un-metered power line for you, let the farm run for a few months, maybe years, it's like hit and run, if the police where to find it, well it's a dozen of miners that belong to nobody, they will seize them, probably sell them for cheap on an auction for someone else to pick them up and do the exact same thing all over again, and since it takes a long enough time for the police to notice it ( if ever ) and with 0 power rate, those farms ROI in 2-4 months with the right gear in place.

This is really not just a bunch of miners running on free power, it's a TON of them, this makes mining predictions way less accurate, you can't say all S9s will shut down if difficulty gets to x and price get to y,  a huge portion of those S9s will only shut down if they fail, burn, or get seized by the government, which might be a few years from when mining with S9 is no longer profitable for anyone who actually pays for power, the same thing happened with V9 or S7, some people think nobody uses these gears anymore, but trust me, there are a lot of them still hashing their way in.

Congratulations g00dwin555, first solo block after the halving and first block on the new server, your years of mining finally paid off handsomely, I will also use this opportunity (not that I am an opportunist by any means ) to let you know and to notify the other solo miners that philipma1957 is holding donation addresses for funds of the pool's server and operations in case you want to donate some coins

I quoted what you wrote.


What I understood from "hands that don't have to sell BTC"  is that 0 BTC has to be sold by those "strong hands", anyway while in the process of searching for that statement, I remembered that I know Matt's business partner Mason (from their company name), it's been a while since we talked so figured out i'd ask him if Blockware S really think that, and his answer was that "Matt will never say such a thing', which means he also understands "don't have to sell BTC" as in 0 BTC to be sold,  but we will just call it a misquotation or a misunderstanding on my side and leave it there.

Now the fact that there are some people like phill or myself who don't have to sell BTC, or even Blockware who run about 10MW of mining gears, has nothing to do with halving, it's all about the power/business plan you have  (Mason also agrees to that), phill explained in details, as far as the halving is concerned it does have a positive impact on the minimum selling pressure but is only valid for a very short period of time (right after a difficulty drop) but it's only a matter of time before miners start adding more hashrate to compete against one another, without the price going any higher, miners will be forced to sell more bitcoin since they will be getting less of it.

Another thing to keep in mind is that the minimum sell pressure assumes that miners only sell enough to pay their bills, which is a good way to run the numbers, but if you think about it, there is no reason why wouldn't miners sell more or ALL of their BTC earnings, I am not claiming the research is wrong, I know Mason for a long time and he knows his stuff, I know and talk to many large miners, and all of them will tell you the same "we are speculating".

Do you want to hear a funny story? I personally know a guy who bought 10,000 S9s that will run on FREE power, this is only one person whom I happen to know, how many others? probably a dozen, who can count all of them and add those numbers into any research? nobody, so will the selling pressure really drop from now on (long term)? maybe yes, maybe no, IMO it's highly unlikely unless bitcoin increases in price and if we stay flat, miners will be in an equilibrium where mining revenue is too slim, and they will probably have to sell most of their btc earnings to survive for the long run.


.

True, but that's a lot of maybes, they could buy more mining gears, they could buy gold, or of course, hold BTC, what I think that at least the majority of large miners in China sell most of their mined BTC to hedge their funds, remember that investing in mining gears, is somehow investing in bitcoin itself, your profitability depends greatly on BTC's price and existence in the first place, if things go south, you lose everything, wise investors usually know how to hedge their wealth.

Do I have proof that 1+1 = 2? I really don't, I just know it is.  I don't know who that guy is but I am sure that anyone who knows the basic of economy and mining won't say



The bold part is 1+1 = 3, really it doesn't matter who says it, if Albert Einstein comes back alive from his grave and say 1+1 = 3, it will still be wrong, and since you mentioned that


Then I can only assume that you misunderstood whatever he was trying to say, could you please quote the part where he says, "miners don't have to sell BTC"? Because that statement is really wrong, I have no better way of telling you how wrong that sounds.

I am glad you got the issue fixed, sometimes the fix is pretty straight forward and simple but we fail to see it, it happens a lot don't blame your self.

I think $1400 for M20s is a lot, below is the average price in Shenzen

M20s > $1100
M30s >currently no stock
M31s> $1500

These are the average prices, you can negotiate and get them for slightly cheaper, you still need to take shipping into account, I am already into these MicroBt gears, my next upgrade will consist of at least 70-80% MicroBT, no more crappy bitmain gears for me.
