That's exactly what it is and it cost less than $40 to mass produce.  They probably spent more on marketing realizing that they needed to make their first catch their big catch because after that the word would get out fast that this is nothing more than $80 of parts with a bunch of hype.  You can buy this kit on Amazon for $60, another $20 for for a flash drive for the block chain and that's about it.  I mean its cool and all, but at $400 I would be sending it back building one for a 1/5 of the price. 

These are all good points Rich

Regarding the power supplies I stick with the same kind of power supplies up until just recently when I changed over to EVGA for my last 5 S7's.  I don't really factor my power supply's voltage bouncing as a reason for the difference variations in miner performance.  If I was have voltage problems then I would think my problems would be much bigger than what I have previously described.  (which by the way I do not consider a problem) I would lean towards mass produced miners over high end power supplies but that is just me.  Regarding HW errors, yes I do get them, we all get them and that is something that would take forever to watch over a long period of time.  The truth is there are several things you can look at to monitor your minors.  The most obviously thing that people look for is how fast can it hash.  Now if I can get it hashing fast but the results are garbage and I am getting a lot of rejects, hw errors, etc then of course that is when I am going to dig deeper.  I wasn't trying to go quite that in dept as the question was regarding frequency settings.  I am pretty sure if you polled people on the forum they would all agree that not all minors behave the same and they doesn't mean we need to start to digging into power supplies/PCIe connections over a couple Ghs.  However that is just my opinion, and please note I completely respect what you had to say it is just not something I would do if personally as my farm is running great.  Some of my miners are over achievers and others are a little under achievers(very little) but overall I am averaging a happy 105TH.  Thanks for your feedback. 

You can build it yourself for around $80 with kits that have everything need on amazon and I am sure those folks are making money on the $80.  So 21.co buying and making in bulk probably made these for around $40 each I would imagine.  Of course there is money in marketing and if they were smart they dumped a lot into marketing early to make a fast push to get the early crowd because I think now that people can see having already figured out how awesome it is to own one, but it is no where near $400 they are putting on it.

Now that they have put the target out there you better believe as open source goes you will have developers working around the clock to provide free payments libraries that will run just the same.  In fact if I understand what 21.co offered was just the tools that are already free to everyone else and then it is up to the purchaser to go and develop.  (I could be wrong there)  But I cannot find anywhere on their site where there is an out of the box payment solution that runs right off their node.  If there is, then my goof and and I missed it, but like I said there are going to be several solutions,  very soon and by soon I bet within weeks for people to start using.  Then you will have the opportunity for people to build payment stations (just like credit card machines but without the banks) such as what 21.co is doing but at a fraction of the cost. 

I think they had a great idea but came out of the gate way too greedy.

Honestly for me every miner is a little different.  With the exception of the 2 batch 7's the firmware is on those factory installed and on one of them I left it at 625 MHz and it mined at the advertised 5TH, the second batch 7 at 625 was performing poorly and I was only getting around 3.8TH so I dropped the freq to 600 and then is jumped up to 5TH.  The 19 others I have are batch 2 (which were advertised to run at 4.66TH at 575 TH), I flashed them with the most recent Bitmain firmware that supports the 600Mhz setting.  When I had the time I found that really going through them slowly and taking my time tweaking with the frequency (and not always up) making small changes has made an incredible difference.  For instance, I have some of mine set at 606MHz and some set 593Mhz.  I do not think I have anything set over 625 but you can certainly try.  Just make sure you are monitoring it closely when you make changes like that. I guess the whole point I am getting at is there is not perfect setting for every single miner out there.  You can have rough guidelines that work for most but if you are trying to dial in your farm, then you need to play with the settings to see what works with your farm.  Also keep in mind not all miners are going to perform at the highest Th rating possible.  Some of my miners no matter what settings I have changed and close I think I have dialed it in, I have had to settle for 4.5Th when I should be getting 4.8  and that ok, its just the way it goes.  If you are interested you can check out my mining set up here

If you like it, subscribe as I am always adding new content and I love audience feedback.  I look at bitcoin as a group learning effort.  In fact your thread has kinda of inspired me to create some kind of video addressing this very issue because I have seen this question or variations to this question come up before where people have had performance issues when dealing with several of the same type of bitmain products.  They are frustrated why two or more of the exact same product do not operate the exact same way. 

I hope this help!

Is Anyone else having this problem?

My rollover is Ghash which is better than nothing, but antpool was on a roll this afternoon and then it when down.  I am not sure if it was scheduled or just crashed.


Bitmain, can you provide any feedback here??

If you want to make crazy fast BTC then you need to go out and buy as many hashlets as you can.  It is the future of mining.  You cannot lose 

I had quite a bit a feed back and also did some testing of my own but I came up with this setup which has made a night and day difference

I am assuming that since you are moving you miner around between different networks that you are leaving it set to DHCP right?

I totally agree with you, I maybe misunderstood your earlier post.  I thought you had the firmware that bitmain was using for the 625 rigs.  However, I have no problem running my machines at a lower setting as I am fully aware for what overclocking or pushing these units to hard can cause damage wise.  The financial risk is not worth it.  That is why I am so against bitmains batch 8 with the 135 chip and them pushing the chips to 700 MHZ.  I think that has failure written all over it and driven by greed.  Just my opinion. 

Absolutely, I would never do that, I was talking about getting the firmware for the other 19 that are not batch 7 to bring them up to batch 7 standards.  I am very happy with thew two that arrive tonight. 

What are you wondering about, how awesome it will be  or what?  Lol, I have 21 S7's 17 of which are powered by COOLMAX ZPS-1600B and the other 4 are powered by EVGA SuperNOVA 1600 G2 80+ GOLD, 1600W Big Daddy's.  What are your concerns or questions?  

Yes,  I just got my batch 7 in tonight and whatever firmware that is on there is amazing.  Of course it is only going to work on batch 7 I am assuming (162 chip version)

Let me know.

Thanks!!

Well I just checked and with the firmware that is on the controller card that is my S5+ it only goes to 500 Mhz.  Which leads me to my next question, could an S7 controller card work on an S5+ card.  I sent the OP a PM to see if he got this straight from bitmain or 2nd hand.  I have a funny feeling about this but kind want to leave it at that until I get more information.  If he tells me 2nd hand, I am 99% certain I know who it is.

Well I am actually running a center piece of an S5+ right now in my farm so that is how I know on the chip count.  Yes, I did miss the  , I thought you might be referring to the the 135 chip unit that bitmain is putting out now(sorry about that).  They put out 135 chip units in batch 6 as well batch 8 which has not shipped yet.  I can tell you one thing, the image that the OP shared is not that of an S7 card.  When I get to my office here in a couple hours I will look at the frequency options to see if 600 is available.  What I do know is that if he was have issues with chips not working then they would simply be x'd out but I do not believe that they would completely disappear.  If he had a 135 chip S7 you would see 45 chips on each line, and one 162 you would see 54.  Like I said, 48 chips is not an S7 board.

Just so I understand, you are using 3 650 Watt power supplies for 1 S7?  I want to save further comments until I understand exactly what your setup is.  However I did get the 11.2 volts you mentioned and yes that is not going to be enough to initiate or boot the chips on the hash boards.  These miners are very finicky about the power.  Even it you were able to get it to come up you would run a lot of errors.  I am surprised by this because thermal take is not a bad product.  It is not my top pick, but I have run one before in my computer with no problems.  For the money you spent you would have been better off buying a couple corsair or evga units and again I am assuming you are talking about powering just 1 S7.  Let me know if I have my facts straight.     

There is no rare 144 chip version, there is only a  162 chip version and a 135 chip version.  This is not an image of an S7.  This is the single section of an S5+ which had has 144 chips on it (obviously the one with the controller card on it which can be moved). 

Well since it serves dual purpose as a space heater I say good job, however if it wasn't, doing that with that rate that the difficulty is climbing it is hard to justify dumping too much money of any into any S3's at this stage in the game IMO.  Unless of course you have super cheap power and are looking to hang on to any bitcoins you earn, but the space heater is a the bonus in this story.  Good work!!

I do appreciate your reply and regarding youtube it is not teach and I make that very clear but it is a place to share.   

33 S7's in your House???  That is an incredible amount of power for a residential location.  However I would love to see the pictures of your miners and the in action the way you have them described in your post.

I am sure you heating bill in next to nothing in the winter.

Have a nice evening!

 

Thanks man, I appreciate the feedback. 

Lol, I don't even know where to begin with your feedback.  So I am going to keep it really simple.  Based on your response you clearly do not understand what a swamp cooler is and the direction of air flow it provides.  That was evident when you kept referring to it as a ceiling fan.  There were so many assumptions in your in your critique that were incorrect it was not even worth trying to correct them to give you a proper response, and with that I had to chalk up your initial introduction/insult of "worse set up ever" and toss it in the trash.  Even if half of your assumptions of my setup were correct I don't think you would be saying that, unless you were just trolling.  Either way no biggie to me.  I love feedback I can use, but yours was useless, and again I don't know if it was a trolling effort or just your lack of knowledge with my particular setup. 

At any rate your signature line leads me to believe you do this for fun and because you had enough insults in there to try empower yourself.  This was a weak effort to troll as there were so many facts that where wrong which makes makes me think you don't know as much as you think you do.  Just a thought. 

A more constructive approach rather than your tear down method which doesn't work on me would be to show me you set up.  If you have all the answers then lets see your set up.  

At any rate thanks for the response and have a Happy Thanksgiving!!
