I believe the S5+ was three modules of 3 boards but I could be wrong.
S4+ I don't think had anything to do with S5 release. It came about four months after the S5, had a worse efficiency because it still used BM1382, and had a worse $/GH than S5 because Bitmain is greedy. The S4+ has four boards, each with I believe a 3x17 unregulated string for 204 chips total. Stock clock 200MHz, hashrate 2570GH at about 0.6J/GH
Thought is was something like that. Never got one but I do remember the s5 was an impressive looking beast. Also never got the s4+ because as you said, it came out around the s5 and struck me as Bitmains attempt to use up the older gen chips they had. edit: Bitmain still has a site for the s5+!!! https://shop.bitmain.com/productDetail.htm?pid=0002015081407532655504JMKzsM067B prolly only for the pic but nice for ref  Of course upon finding that I duly grabbed the pic for my pics archive. |

There was an S3++ at one time, limited distribution but they were testing the S5 string concept with S3 chips and already had an S3+ model.
I can confirm, a few aliexpress stores had it listed for around 265w power usage and around 100$ price with shipping to the usa. Looked slightly different compared to the normal S3, and I actually wanted to mess around with one for a bit to see how it worked; S5 was released shortly after it was released, hence limited distribution. Same game plan Bitmain used with the s5+ they did briefly just before releasing the s7 though the s5+ was just more blades (I think was 6) ran off of 1 controller and packaged in a bigger frame.. They also did the s4+ (think just had more chips on boards?) but not sure how that fit with the s5 intro . |

Does anyone actually make a 3840x2400? Besides the 15-year-old IBM T221, I mean. 16x9 kinda sucks.
I think that is what the mammoth HP 31" monitors provide as well. Not sure if still made and the 2 we have came with a now 5-year old Nikon inspection system.. I am now in love with the UHD aka 4k TV's... Got 32" one for the HMI on our latest laser test bed and it is -- marvelous!. Talk about real estate to spread out the various windows I have open... 4 mo ago it was like $380. |

Bitmain so far is the only Bitcoin miner maker that sells to the Public on a regular basis. Once again they are sold out. Avalon *is* taking orders and should start shipping their miners Nov 21st. In the past they have been trustworthy. There really are no other reputable Bitcoin miner makers -- but there ARE a lot of scammers so beware! 1st rule of mining: NEVER spend money you cannot afford to lose. If you have spare cash to spend then think of it like a vacation at a casino. Maybe you will make money, maybe not. 2nd: ONLY buy new miners direct from the manufacturer or their authorized distributor as-listed on the companies website. It is the only way there will be any Warranty on new equipment. It is also the 1st step in avoiding scams. https://Bitmaintech.com for s9's https://canaan.io for Avalon miners 3rd: If starting out 'to learn' then look for a used s7. Much more manageable in terms of noise and reliability. Also a helluva lot cheaper that the s9 is. On the heat: Plug in and run 2x 1,250w heaters in the room for a day. If it stays a comfortable temp you would be fine. |

Hey guys I read the posts here and am trying to piece together myself how to rig up my first S9 & APW3+ PSU. I also live in Canada, and have a 240 V Nema 6-30 straight blade receptacle in my garage (same kind used for ovens / washer etc).
I'm trying to figure out how to best adapt this receptacle to plug in the APW3+ PSU with the standard C13 power cord.
Any idea's on appropriate adapters? I would prefer not to have to rip out the receptacle, but I will if I have to.
Go to home depot or whoever and buy a male 6-30 plug. Take normal C13 cable, cut off the 5-15 (normal 110v) plug and wire cord to the 6-30 plug. Works but take care to use the heaviest gauge computer cord you can find since you are using a 30A outlet... Best/safest way is to search Amazon for a 4-outlet 208/240v PDU that can plug into the 6-30 and break out into 4 outlets each protected for lower current. While there also get a couple IEC-C13 male/female cords as that is what the PDU outlet sockets will be. |

The regulator will be able to safely handle at least 12V. There's no reason to build a device capable of drawing 50W and make it run on 5V only, that's foolish. Biggest problem with 5V power will be the fan.
Even better then. Dirt simplest is for user to size an ATX supply to fit the max stick farm load using the 12v leads and use the 5v part of the ATX to power the controller. |
|

Sure, if you want to rig it up to a USB port for power but then you couldn't super-overclock it to 50W if you wanted. Even a moderate hashrate of, say, 60GH would want 5A at 5V.
Agreed. Plus as long as the regulator can safely handle say 6-7v on the high side, 5V bricks/wall warts are readily available on Amazon, eBay, etc. to power them. Not to mention that any little ATX supply like say a 250w will have more than enough 5v power to run several 4-chip boards at respectable speeds... |

Has anyone had luck making the S9 a bit more silent? under powering them seem to help at all?
And does the antminer software have the ability to change it's hash rate based on time of day? ramp up during day when I'm away, be a bit better when I'm home etc.?
Read back in the thread. Been discussed ad-nauseum here. To all the above - no. Pre-autotune firmware you could tweak them a little for speed and fans, now that is impossible. |

Since Avalon gave us the finger by not accepting BTC  just ordered a B23 which will now put me at 10x of the s9's. Canaan/Avlon's loss as I would have rather spent the $1700 on 2 of their miners but oh well. |

DPOT adds a layer of complexity I would rather avoid for a quick-turn project, since that means tying a microcontroller into the signal path when a CP2102 would handle all the chip comms.
np. Then the dunkers just have to solder on extension leads to move the pot away from the fluid. Thinking about doing that to my Compac. Got a 1gal sample of Silicon based cooling fluid from Clearco so might spare a few oz to test stick-in-a-jar  |

So you want me to design the board to fit that form-factor? Or just that the general design is a good idea? Because I don't really feel like designing for an existing form-factor, or I'd probably pick something like the U3 instead.
Just as a suggestion for general design direction, certainly not specific. Really mostly depends on how reuseable you want the PCB layouts to be and you try to design around that with future designs in-mind Only other suggestion is just a bare open format so the DIY'rs can have fun making Lexan cases or dunk them in a fish tank full of oil to highlight the pretty flashing lights (meaning dpot to set vcore vs a real pot) |

Sorry to be terse, but this is just another incredibly busy day in a week of probably minimum 12-hour days. Those BFL giblets are a lot fancier than I care to make for a short-batch fundraiser.
I was thinking more along the lines of it sans cover. Is just a thick aluminum baseplate, circuit board and topsink/fan on top. Should fit a 4-chip board nicely. Pop one open a take a peek. |

ack.
Ask Luke Jr. about existing support would be best

I was thinking of just finding one of those cheap 4x4cm heatsinks with a built-in fan and tucking four chips underneath it. Probably just in case, put a temp sensor under there that kicks off the power if it reaches a factory-preset threshold. The whole thing would be fairly small, maybe 8x8cm to have room for power and node-level stuff. If anyone wants it, anyways.
I'm waiting to hear back from the codemaster about how hard it'd be to extend the Compac driver to handle multiple chips. I don't think it should take much, but then I don't have any data to back that up.
Heck if I know what BFG supports. Never really used it. And whether or not it's compatible with current BF will depend on how you interface to the chips - they don't exactly use a standard protocol. How does BFG talk to the 28nm, and how do you know that because I've never seen any of their 28nm in the wild?
I guess for a start, ask Luke Jr. directly.From reading his thread he seems more approachable than CK- is... Avalon and BitFury chips along with a slew of others are listed as having build-in code. The compac code uses same base as the Bitmain code per the docs. Start here for the list https://bitcointalk.org/index.php?topic=877081.0 - it's as long as yer arm... edit: I'll take a few pics of a BFL Cube inc the innards tomorrow. Is about 3" per-side. Very nice little package. Then nvm. Still gonna fire one up again to join the lotto address. |

no BTC payment - no deal
Agreed. If they directly accepted BTC I would pay the bit more in $/W/THs viewing it as a good and hopefully more reliable upgrade from my remaining s7's at work vs getting any more s9's. Too bad I ONLY buy miners with earned BTC. The last time I used Fiat aka 'real money' was in April 2014 to buy my first pair of s1's from an Amazon dealer (JonesGear) located nearby in Ann Arbor. Haven't spent a single cent since in Real Money. Currently that seed money has grown to >165THs all paid for in BTC from farm income. I am not about to pay the bit more PLUS the % it costs to exch BTC to dollars to buy them. Screw that noise. |

I'm not sure that question has an answer. The original Compac didn't have a "target" hashrate, that's the whole point of making it with adjustable voltage and frequency. Set it where you want it.
I can say that for the ~10W it took the one-chip to generate 20GH, this one should get closer to 30. The 5W hashrate, instead of around 13GH, should be more like 18.
Well damn you... That lil' Compac I bought from Phil works great. So far, with a very tiny fan wafting on it I'm running 300MHz, still almost cool to touch. Using Bfgminer is painless to run (driver built in) vs CGminer + Zadig. Brings back memories of the 2 lil 10GHs BFL Cube miners I started with in Feb 2014. Bought them through TigerDirect and the damn things got me hooked within a month. Again, with them CGminer was -- confusing -- but Bfgminer found them right away. Now that BFGminer is running anyway at work for the Compac might as well have 1 cube join my lotto instance on solo.ckpool.org  And... speaking of those BFL cubes: They draw 60w each for 10GHs vs what the Compac gen-1 provide. So, maybe the 4-chip version in a similar form factor? Already uses the barrel plug so that's perfect. Anywho, love the stick I got so count me in for at least 1 of the Gen-2 2x chip sticks. Finally -- BFGminer already supports Avalon (not sure about A721) and BitFury chips up to at least their last 28nm ones. Is BFG also plug-n-play with your samples? |

From what BitmainWarranty said further up this thread, there is short turn around time for the repair of most boards. This would surely indicate a common problem on most boards that is likely to fail. Surely making us aware of this common problem might help miners from losing hashing time sending boards for repair?
Been there, asked that of BitmainWarranty several times. No answer from them as to what fails, just a lot of excuses why the repair process and results are not documented. |

But it would be nice if they could get back to me about picking up another hundred or so samples, cash up front. The last reply I got from Punin was September 27th and I've only emailed three times since then with no responses yet. Might take a bit more badgering. Right now I can prototype one pod and two sticks; with another 100 ASICs and 15 comms I could prototype a TypeZero board, five more pods and another 7 sticks. That'd give me a lot of stuff to play with and some to send out for y'all to play with.
Agree 100%. BitFury has once again gotten a Golden Window of Opportunity here! They cannot afford to blow this with the Avalon horse (edit) almost but not quite in the gate yet. And now Avalon is out the gate but still far behind the stumbling Bitmain s9. Will BitFury make it a 3-horse race? |

Between the two of you and the cores I already have, that's about 12K chips. Heck, we should really figure out a way to get Bitfury's attention since Punin hasn't responded to my last several inquiries.
Would be nice if they would provide chips in growing batches on-consignment with an extended pay-before-by-date, say 2-3 mo or whatever you work out with BitFury for time needed after chip delivery. If they could start by sending you enough chips for say 10 or more full-up miners to use for proto/prove out and hopefully sell (I'd buy a working proto) it would be minimal exposure to them and one helluva show of good faith from BitFury. After that, as you've seen, there IS a sizeable market out there wanting to be served. hey that would work to he would sell a lot and make some profit but best of all he stays in business and second best we get what we want a very afford able usable miner that can be used in homes . I still don't get there reason behind not selling to homes . I mean i no there are some but i call them excuses. not that high priced miner bitmain passes off as a home miner, it may be but .' I'm sure side would pay them ASAP he seems very honest about that kind of stuff . be nice if they would . The only reasonable excuse I can think of is BitFury's supply of chips vs fulfilling prior demand for the chips destined as internal usage (for the mobile tanks they say they build/sell) and prior very-large external customer commitments. IF they are actually producing chips in volume I'd think the back order for chips should be more than enough to keep their Foundry (TSMC) happy with BitFury's monthly order quan. Yes compared to that, Sidehack's chip consumption would be 'small' but still by no means insignificant to BitFury's bottom-line. Throw in the PR value -- Priceless. |
