Are you planning Breakout boards for these as well ?
I'm currently checking how to make a batch of the 2 chips miner. And maybe if I can find more than 24h in a day and more than 7 days in a week, I'll have a look at an 8-10 chips board, but it's unlikely for now. |

Price is already released. 1.290,- $ each
let's see how much they can sell at that unrealistic price I'll get at least one to play with, as I try to do with most of the miners. |

How much do you want for the 3 of them (shipped to France)? |

@OgNasty: i used the sp30 to dry my hair!
it's almost as good as my future tumble dryer project. Space heater... done Swimming pool heater... done Hot water heater... done Next step, the hand dryer.  Beware bitfury, your lightbulb won't stand a chance against us  |

0.65 BTC INC SHIPPING TO UK ? make it 0.5 and you provide a shipping label ? if he doesn't take it, I'll take the lot at this price + shipping label |

Technically, 5MH at 3W/MH is possible using the upcoming SFARDS chips. But you'll only need 2, maybe 3 chips. 2A * 5v = 10w. 3w/MH * 5-6.9MH = 15-21w They didn't even bother to do some math. And don't expect to draw 15w from your standard USB port... Afaik, the "minion2" chips they are supposed to use doesn't exist. Their SHA2(5)6 usb miner is even better: SHA26,
Hashrate: ~100GH/s out of the box, up to 120GH/s overclocked,
Power usage: ~0.75W per GH,
Dimentions: 28x60mm without usb plug,
Voltage: 5V
Power requirement: 2-2.5A 0.75w/GH * 100GH = 75w 5v x2A = 10w It seems that besides hashing, those USB stick are even generating the extra power they need to run pictures are simply some old Block erupter USB with a photoshopped logo on it. Don't waste your time with them. For in stock scrypt miners, you should search some second hand Gridseed blades/G-black. I'd avoid Zeus/Gaw miners since efficiency is worst than Gridseed, and they don't like undervolt to acheive better efficiency. If you can afford and find them, Alcheminer 256/MAT excalibur could be a good choice, but they don't work weel on all pools. KNC TITAN is overpriced, and it's KNC, but the most efficient option available right now. |

^^^ Looks like a Gridseed case.  I still have a bunch of my gridseed accessories. I look forward to updates J4bberwock. I'll be keeping my eyes peeled for a group buy thread.  The board is an upgrade kit for the gridseed pods. |

I don't know for the G black (still haven't got one in hands), but the heatsinks on the G blade are designed to dissipate something like 200 watts.
From what I can remember, my first fully overclocked G-Blade was drawing 350-400w.
With SF3301, 200 watts would be 5-6 chips hashing at a total of 400-500GH SHA, and 10-16MH scrypt on each PCB.
The number of chips on board is probably not high enough to make it economically interesting for the end user, but it can be done.
My dev board is 150x100mm
How about 8 chips, running at .6 volt 450 Mhz (BTC about 570 GH/s) .8v 450Mhz (LTC bit over 9 MH/s) option? Should be easy to fit on a 4"x8" PCB (perhaps a bit of overhang on one end to fit taller caps if needed kinda like the original GBlade boards), and the common clock in theory should make the board design a bit simpler and less expensive? Might be better to have non-common clocks kick the LTC side up to the .9v 700Mhz (15ish MH/s) option. Current pricing on the SF3301 chips might make this a bit hard to keep to a reasonable price though - $300 or so would be competative with anything currently available IF doable but the SF3301s alone would be $240ish.... What you are asking for is one panel of the SF100 miner. You have an estimate of chips price, then, add the price of the voltage regulators for both sides (BTC + LTC), heatsinks, and your final price won't be too far away from the unofficial SF100 price. I'm waiting for a few informations regarding the 2 chips boards before I can confirm that it'll be a viable miner that's worth manufacturing. The design isn't fully fixed yet for the voltage regulator. The first board uses a converter with integrated MOSFETs to save some space on board, but the definitive one may use a standard pair of MOSFETs like the old gridseed pods/blades to reduce cost for the end user. |

thanks for the replies to my queries the nova has single rail pcies and same problem i enjoy collecting power supplies so im open to a suggestion or a definate to the BEST psu in terms of single rail and watts budget in the area of $150 £100 ish as my £350 paper weight is annoying me
cheers
Cost effective option for mining will be server PSU + breakout board. Wherever ou buy them, they will always be more cost effective and reliable than ATX PSUs. For a single S5, or 2 underclocked, a DPS1200 FBA off Ebay or similar places will cost 25-30€ Breakout board + 8 cables will be around 60€ shipped. But if you already have several single rails PSUs over 450w, you can use a separate one for each panel of the S5. I assume you don't have a second S5 available, or you could try to swap controllers. Also, you can try to start with only one panel at a time connected for the data cable (16 or 18 pins depending on revision). If nothing works, check if it's still under warranty and send the whole miner to the address Bitmain will give you. If it's not under warranty, and depending on how much you'd want for it, I may be interested to buy it to salvage some components for my projects, (assuming you'll ship from UK, and I'm in France). |

Don't message me about price, delay or anything, but here is something that may be available sometime in august:  Can I pm you for specs? would love to know what the gear can do. It's not fully working yet. Because it's BGA (you can't unsolder them and use them again), new chips are needed for more testing on another board. They should be delivered on monday. It'll be on the high side of the specs for LTC (max hashrate) and low side for BTC (best efficiency). |

So .. I have heard a lot about neoscrypt, however I came a doubt, euu a friend and we were talking about buying a asic of innosilicon a2 terminator asic, however I have no idea if this works with neoscript .. could they tell me for sure if it is possible to mine neoscrypt with this kind of asic or only with GPU ??
no neoscrypt with asics, GPU/CPU only, at least for now |

I just connected my 4-cube Titan incl. Controller to a DPS2000 PSU. Well, not hard to imagine that the PSU is getting hot. How do you cool your PSU? Any recommendations are welcome  Just going to raise this question again. How do you cool your PSU? I tried to power an Antminer S5, but unfortunately after ~20 Minutes the PSU switched off and was hot like hell. How do you solve this? Sorry, I totally missed this message. here is the way I'm doing it with 6x 60mm medium speed fans in push/pull configuration: http://imgur.com/a/4UWcr#6http://imgur.com/a/4UWcr#73 stronger fans can also be used on a single side for cheaper/louder configuration. The metal spacers I used in this setup can sometimes short a component to the case (it happened one time to one customer), so I switched back to plastic ones:  |

Hi:
Is it possible to solder the cables directly to this kind of PSU with out the need for breakout board like other lower server PSU ?
thank you.
Here are some pics of how we made the harness. My buddy owns a cable manufacturing company and even using $120,000 of equipment, the time and effort was not worth it. I only made these because of the delivery time to get J4bberwock boards for the first 52 Antminer S5's. I highly recommend not even consider doing harnesses and just buy the boards. The equipment we used to do this project was an auto feed wire cutting and stripping machine that did all the 10 gauge black and reds. Then we used an automatic stripping machine to get .6" on the pre-made PCIE wires we got from klondike_bar. An ultrasonic welder was use to join the wires. Had to use a 150 watt soldering iron to join the welded pads to the power supply. There is also a shot of the power meter when the room was hot and the fans were at max, it was drawing 3785 watts.     I put in bold letters the advice from the only guy that did it to my knowledge. |

Almost there:
so all this is in that case is a updated version of the first Gridseed , wonder if we can upgrade the Gridseed g- black with this all we would need is boards that fit those Heat sinks ). if it Plugs in the same way etc .or some one fits boards for those heat sinks etc.. That boards looks about the same size as the Gridseed g- black boards, i know that's just a test board. I don't know for the G black (still haven't got one in hands), but the heatsinks on the G blade are designed to dissipate something like 200 watts. From what I can remember, my first fully overclocked G-Blade was drawing 350-400w. With SF3301, 200 watts would be 5-6 chips hashing at a total of 400-500GH SHA, and 10-16MH scrypt on each PCB.

$1,499 for Alcheminer including shipping to Russian Federation. Are you agree?  They are completely sold out. and they did 599$ + shipping (was almost 300$, if I remember correctly) on a batch of used units That's the price to keep in mind when buying used ones from forum members |

Looks good, does it use the same communication as gridseeds? Pretty much want to know if new software would be needed or a pi with minera would be ready to go with this? the current software can be found here: https://github.com/sfards/ASIC-SF3301/tree/master/miner_codeBut there will probably be implementations in CGminer and/or bfgminer as soon as the hardware is shipping. Sounds good, what quantity of these do you plan on making if you do even plan on making a batch? I really like the design and well not the price of sfards main product. This is just a dev board, it's not economically viable as a miner. Even with a chip price way lower than the 100$ for one sample. I'll have a look at my BOM, but without the chips, I'm probably already over 150$ for one board. |

Hey J4bber, you forgot to include the Overclock switch:  Lol No, it's software activated:  |
