also: how about modifying the design files to include a micro-usb port or full-size USB port? Its silly that you ship these without a $10 component that must be ripped from a pc or ordered online from amazon. (this is causing bargraphics a 24hr delay on the first unit VMC shipped out to anybody)
Yes, it was my fault that I did not include the cable. However, I was trying to ship it fast, my bad. and what about the other question? @Sebastian yeah, it's "upside-down," and ken has explicitly stated that it's a dev board. If you look either in this or the "UNmoderated" thread, MrTeal points out that the boards in the bags are probably a different revision (and he posted a pic of that rev.)
Yes, this is the board that we are building 5,000 in April. Bulshit plastered over with more bullshit. You were asked for photos of products being shipped now. You posted a pic of a dev board which you claim you'll be making in April (it's April already, BTW). Edit: Crop from the pic posted by Bargraphics. Ken is reselling HashFast boards -- the "reference design" story is just that, a story. These boards were made by HashFast, on their production line. Unless the revision stickies are integral to design. HashFast FastHash  We manufactured these boards, we purchased the the parts, we purchased the PCB, and we paid the CM to assemble the boards. We have 3 different CM's working on this project at the current time. One of which is the same CM Hashfast uses.You bought pre-fabricated PCB (presumably from hashfast since it has their stickers), hashfast chips, and used a hashfast assembly house.

This is my legitimate question, since it went unclear for weeks what type of chip you would use and it was hashfast. Now, it almost seems like the boards were purchased from hashfast as well, rather than your own PCB fabrication with Hashfast design files as you previously implied. Whats the production cost per board?having boards for sale is a step forwards, but I hope a custom ASIC is still the focus. |

Marcel/aka lambchop you objectionable sad little man here are the facts for your small brain: 18 miners sold this week at a price of $2,000 each. 18x2,000x365 = 13,140,000 (there are 365 days in a year and 52 weeks) So that's an annual turn-over of over $13 Million dollars - from a side project of ACtM's. Go back to your cave Troll-boy.  sorry what? Why did you multiply the weekly sales by the number of days in a year and not number of weeks? Here's the real number you were trying to get: 18*$1,500*52 = $1,404,000. Thats about 1/10th of your estimate |

That PSU actually has 720W of 12V power - that is good for a pair of stock units that should draw about 300-360W from the PSU (and 10-20% more at the wall). The issue primarily lies in smaller power supplies, generally anything thats not 80+ silver or better while being <600W has a cheap 12V rail or multiple 12V rails, and 12V is often 11.8V at higher loads. I run 3 overclocked units (393,387.5,393 MHz) on a AX1200 GOLD Corsair supply with no problem, pushing about 90+% load on a PSU that uses quality components capable of being pushed to the limits. A 500W PSU is designed for a windows XP system that will only idle at 30% load for most of its lifetime |

Even located in Canada, mining a european pool and registered in Belize, the IRS might want taxes because Ken is US citizen.
+1. The company would probably not be taxed for mining if mined outside USA, but selling Bitcoins/miners, and even ken's personal income would all be subject to taxes since they take place in the USA. (You can register the company in belize, but if ken is answering questions and accepting orders while in the states he will surely be subjected to the relevant taxes - otherwise every unscrupulous company would base themselves in a low-tax country like belize |

Does the S2 have wifi?
I received an email direct from Bitmain indicating that the S2 does not have WiFi. Cheers makes sense. The S2 is designed with serious miners in mind - and that means the grreat majority of users will have ethernet connections available to connect (or can get an adapter/AP router) |

I believe the price per GH/s will drop below 0.5$ after a few months. We won't see 1600PH at a price >=0.5$
Why not? We won't have much competition. Knc will have chips of equal performance but 20nm means it will be much more expensive and slower time to market. I think our biggest competitor will be spondoolies with their next gen 28nm chip but I doubt even they can match our $/gh. the competition is the fact that the 40nm chip isnt on sale yet - gen1 is worthless. Once the chip is put into working boards in a few more days/weeks then we can say there is no competition  |

thats skeezy to call some guy's parents.
IMO - he was paid to ive people information about pump and dump schemes. He told them it was going up (it actually went up a bit), and then it got dumped before the suckers could sell theirs off first.
1) caveat emptor - dont give someone your money just because they claim to know the future
2) abusing the kid's innocent parents to get your money back is just as terrible. Maybe i call your mom and tell her that you are ganging up on some 20yr-old and his family?
hopefully a few people will go forth a bit smarter.
...oh, and FTC is going to the moon at 2:30 PM EST. if you send your bitcoins to me i will personally buy in for you at that time, and even sell for you so that you don't have to do any work yourself

And . . . with my latest 4.2.2a binary, you can do something a little better if you are technically able to: If you instead edit /etc/init.d/cgminer And a few changes: $APP --lowmem --bitmain-options ... to: #$APP --lowmem --bitmain-options ... And: start-stop-daemon -S -x $APP -p $PID_FILE -m -b -- $PARAMS -q to: start-stop-daemon -S -x $APP -p $PID_FILE -m -b -- -f http://mywebsrver/ant.json -q And on your web server you can put a file ant.json that is the full cgminer configuration for your ant Make sure that you include all of something like this: {
"pools" :
[
{
"url" : "http://pool1.com",
"user" : "user1",
"pass" : "pass1"
},
{
"url" : "http://pool2.com",
"user" : "user2",
"pass" : "pass2"
}
],
"lowmem" : true,
"bitmain-options" : "115200:32:8:40:350:4d81",
"api-listen" : true,
"api-allow" : "W:127.0.0.1,R:192.168.0/24",
"quiet" : true
}
And if you ever want to change the config it's just the one file on your web server. (which is useful if you have lots of ants ) anyway to have it give a different clockspeed to different units? most of mine ll run at slightly different top speeds |

Just for fun.  I'm will buy a new PSU and try it again. I really hope it is not a broken blade. And i know what you mean. I don't know how it looks inside the PSU. Just because the cables are separated doesn't mean they are not splitted. thats your problem there. That looks like it came from the 'used' bin at a salvation army. Its pretty important that you use a quality power supply (single rail, brandname, modular if possible, minimum 600W) in order to get good results. I expect you are either tapping multiple wires off a single rail or the rails are generally poor build quality. Its not at all uncommon in PSUs not rated 80+ bronze or better. You can try the 2x2 pin ATX MOBO cable. these usually have thier own rail in a multi-rail supply since the mobo is expected to draw lots of power |

Cooling questions folks:
Given my limited knowledge of thermodynamics, does anyone have some insight on second fan placement? If they are of differing RPM, I would assume that you want the faster one blowing out of the end of the machine, thereby pulling slower fan air and environmental air through the machine as smoothly as possible?
Any other setup (the reverse of the above, each fan blowing inward) seems like it would create turbulence and not cool very effectively. I'm wading through this thread now, if anyone has any specific links to posts.
Thanks again.
there is a lot of openings for loss of air pressure across the unit. the second fan help ensure airflow at the exit side that may otherwise go out the top or bottom edges. secondary fan is not really necessary IMO unless you really want to try and bring down temps and noise ever-so-slightly |

Hey Folks,
Can someone please do me a favour? I'm on a restricted computer for the next eight or nine hours, and I can get to direct links, but not main domains, oddly enough.
I have the Corsair CX600. Can someone please post a direct link, on either Amazon or Newegg, to the PCI-e extenders I need to cut to power S1s? I would really appreciate it.
the newer models all have pci-e ports. Only units bought in december/january did not have those |

Klondike bar my power source is antec earthwatts 650w I bought used....mabye its the problem and is it my router up default gateway to put in the default gateway for the miner or is it the router ip?
ok - so your network IS 192.168.2.1 thats good - did you clear the ipv4broadcast box and leave it blank? your PSU could be an issue if the PCIe cables both run on the same 38A rail (there are 2 38A rails) - but it seems like there are a few ae-650W devices in various configurations of rails and efficiencies (1 type actually has 3 12V rails) unplug power to the secondary blade and disconnect the data cable from the blade also (so that your unit is only going to run with one blade) and try booting up like that. I dont think its the issue, since power problems typically show up once the unit is hashing but is either rebooting randomly or hashing slowly. |

Many thanks for a guide. I see that yous are modifying S1 left and right  I have one spare blade with half of the chips not working and was wondering if there is any way I can use this half broken board ? It's the board which didn't have controller board attached to it. Is there any way to connect that board to RPi or even to existing and working S1 ? Thank you very much there may be a way to connect it to an upcoming S2 unit if they simply modified the voltage/clocks on the current blade design. Many thanks for response Klondike I'm incapable to try anything like this on my own so thought it might be useful to ask on here. So many gurus on here Well I will keep board just in case Yeah, i cant think of anyway that you could connect it to an S1. AFAIK neither: a) cgminer settings are capable of detecting more than 2 boards b) 2 cards cannot share a dataline for double hashrate. you would either see a lot of duplicate throwaways or HW errors. I do not think it is a 'shared comms' type of connection where multiple boards in parallel would be capable of sharing instructions or hashing 'n-times' faster |
