280 day and 25% profit is for this ambiguous future not that big deal, even if bought 2.4BTC now and wait 280 days bring the same profit imho.
I'm sorry, you need to clarify how holding 2.4BTC for 280days will magically earn interest - I think 2.4BTC is a fair price where the unit should make back its cost so long as there are no extraordinary circumstances |

Am seeing a lot of HW errors when i overclock it to 400. I also see a lot of X's but the my pool shows that it is hashing atleast at 188 - 190 GH/s. Any suggestions what might be the issue.
But at 375, it works like a charm with Fan speed at 2300 and temps (45 / 48). No X's at all.
My setup consists of :
I have added a 60 CFM fan at the other end of the S1 to pull the hot air.
Corsair CX 750M (powering just the S1 + 1 X 120 MM Fan)
Have you tried blowing a fan directly on it. The over clocking isn't very stable anyway but temperature would be the biggest factor that you could control. My temps are in the 30s but it's not over clocked. TEMPS: they seem fine - my units run at 48/47, 51/50, and 54/53 (the last one is from the very first batch) at 400MHz FAN: adding the second fan is good, sucking air out is ideal PSU: plenty of power, +12V@62A is far more than enough to run at 400MHz (roughly 500-550W) my suggestions: 1) what is your pool? check if its sending high/low difficulty that isnt optimal to your 200GH 2) enough power wiring? you should use 3+ and 3- lines per blade. more is overkill for a corsair wiring and less may cause issues 3) add small heatsinks to the large grey inductor blocks. they get fairly hot and a little bit of extra cooling for them may help prevent ripples or other 12V power effects 4) sometimes the unit puts things to 'x' arbitrarily or deactivates chips during config changes or during any outtages. REBOOT the unit at 400MHz and see if its fixed. You shouldnt be having issues at 400MHz imho |

I just looked and it seems GHASH is around 31% now, and as a result eligius went from 11% to 17% almost overnight

Yes indeed I am coming close to hitting that home miner limitation wall. I am in the process of looking for a commercial space to lease. Right now seeing how it's -19 degrees C outside heat extraction is not the issue, but come summer I won't be able to add any additional hashing power.
As far as electricity costs for me it's 0.09 per kWh which is not bad, but damn 0.02 is amazing.
where in Canada? I am hoping to look into hosting options for mining in the next few months because come spring I will be approaching my electrical capacity (apartment) and also seeking to deal with the heat. It would be pretty nice to set up mining collectives for industrial space with large mains and cooling capacity In Southwestern Ontario. If I find something suitable and you are willing to co-op with me we can definitely do that. Having more purchasing power will also allow us to get a higher quality space. agreed. I would love to see/create some sort of space in the GTA or toronto itself - Im sure it wont take long before a lot of peole start looking for someplace else to host thier several kW of mining rigs In the GTA yes, in the Toronto city core or periphery I'm not so sure. The lease costs will likely be high as might the electricity costs. What do you pay on average per kWh? I'm in for a good hosting place in GTA. Please let me know if you found something. I need to look into details - I dont see the idea being viable *yet* per-se, but come march and the warmer weather and lower profits I think there could be a lot of energy-hungry, hot equipment that people no longer want in thier homes/apartment/offices and a centralised location (maybe even private pool) could be the best way to go. I persoanlly will be trying to relocate >2kW of equipment by then |

one more picture   that still shows a cluster of 'thermal resistors' rather than an ASIC what a clusterfuck by BFL, and a demonstration that given a second chance, they still cant meet any sort of deadline |

nice USb, but i dont understand why - it draws far too much power for a USB port, so for the effort of getting it to work it seems like a much easier idea to go with the one-string or other design that uses 12V and holds more chips

received mine today - mixed opinions on my side:
1) actual coins are very nice, and very similar in size to a 1oz silver coin
2) would be nice to see actual silver coins and bitcoin versions in various denominations as well - the make your own coin approach is nice for gifting
3) the coins were wrapped in a page from the obituaries - surely using something besides the local newspaper could be a tweak in the future
4) similarly, the holograms were in a folded peice of cardboard small enough i almost discounted it as garbage or part of the shipping box.
5) the holograms would be nice if a little more detailed than just an 'L' - once that just says 'cryptovest' could be quite nice
update: it's worth noting that i put a hologram on a coin and removed it 10 min later using a small amount of rubbing alcohol as a weak liquid solvent. The hologram still became 'voided' from removal but not because the 'void' patches stuck to the coin as expected. only 1 or 2 tiny bits of hologram were left on the metal, and I feel like using another solvent like naptha may have worked better - Im not totally confident in the hologram tamper-proofing (but i guess thats not the purpose of these DIY coins), maybe future versions can be improved

GENERAL QUESTION: what pools and settings do people use? ghash.io has become dangerously large and I have moved my 600Gh of mining to eligius to do my small part. Right now reported hashrate seems on target, but just curious if people have opinions on best pool or settings w/ regrds to antminer
I've been using BTC Guild for a while to minimize variance, which may not be quite as good from a network-security standpoint (though they're currently less than a third of the network). P2Pool would be the ultimate in decentralization. I've used it in the past, but started running into performance issues on the hardware I had available. I think I'd need to at least throw more RAM and/or an SSD at it to get bitcoind to respond in a more timely manner to the queries P2Pool throws at it. I moved to eligius and am seeing 590-600GH average from my 3 antminers (375,400,400 MHz) Everyone seems to be getting very good hash rate out of the units, yet to see any dead chips. one unit has a single chip with an x (it had about 4 that seemed caused by the pool switch but cleared by a reboot) and is at 200GH. If the chip is actually not working, the hashrate loss is minimal. i plan to reconfigure some of the power lines and cooling soon and that should help bring temps down from 51-53 to 50-51 |

With much respect to Bitmain, am I missing something here guys? Even at 2.4 BTC @ 819 USD per BTC = 1965 USD and 20% difficulty increase (even thou I've been generous, some show up to 30%) that will be about ~ 587 USD overall profit by 280th day. Sure, plus price and difficulty flactuations, we might even add up to 10-20% there. But is it the max you are aiming to get from your devices? Calculations via http://bitcoinwisdom.com/bitcoin/calculator so 25% profit? I don't understand your confusion, 2.4BTC is a perfect price IMO |

Guys, I have an antminer with an antec 450w psu. 360 is the specified power draw as per the initial group buy page? Has anyone had any good results with overclocking within this limitation?
Thanks.
a 450w psu probably has only ~350W available on 12V so you may have difficulty obtaining 180GH stock speeds. overclocking is out of ht equestion (if there was 450w of 12V, 190Gh might be possible) |

Per the PR ..
~45% of GHash.IO hashing power is BitFury ASIC based miners ..
~55% of GHash.IO hashing power is independent miners ..
So, the problematic bit is the 45% of hashing power in the "cloud mining" product ??
Because that hashing power is under the direct control of CEX.IO/GHash.IO ??
Are we not individually; by either participating in the "cloud mining" product or as
members of the GHash.IO mining pool; causing the very network hashing share issue
you all are ( over ) reacting to ??
Triff ..
is the 45% bitfury just thier own private mining facility (which is bitfury based) or does it also include all the pool members with bitfury systems (which is what im hoping) Im not sure how they would determine this though, besides looking at worker names (ie: username.Bitfury1 vs username.Avalon1 vs username.mydamnfineminingrig) |

And remember in reality you need to pay some pool fee and/or some downtime due to various reasons so remove 5 % at least
are you serious? 5% less?  downtime?!?!?!?! lol... now I'm starting to understand why is better sells miners than mine with them...... 5% may be high for downtime, 1-2% is more likely (in a 24hr day that assumes the miner is not mining for 15-30minutes (internet outages, setup rearrangement, tweaking/tuning, etc) as for the calcs, assume the miner arives at the end of february if lucky, not at the beginning |

May I know does Antminer comes along with Wifi antenna ? If not which wifi antenna is suitable ?
it does not - basically any screw-on antennae will work, including the kind for wireless routers |

Can anyone offer advice on a Antec VP450p psu which has only 1 pci-e connector. It seems the second rail is only for the cpu power and everything else is on rail 1.
It's a 4+4 atx12v connector for the CPU - How should I connect this to one of my boards? Each connector has two yellow and two blacks. The PCI-E cable is on the other board.
Thanks.
I am using a 600W PSU for an antminer, with 1 of the 4pin ATX connectors per board (only 2+ and 2- per blade). The wires have almost no warmth on my setup but i think they may be 16AWG rather than the typical 18AWG or 20AWG |

I know I'm jumping in on this halfway and I'm going to get caught up ASAP, but all morning I've been wondering the same thing... What have the OTHER pools been doing to make it more attractive for miners to leave GHash.io? Why are all the efforts focused on getting people to leave?
eligius has 0% fees, a simple structure, NMC merged mining, and also shared the tx fees. I moved 600Gh there already |

Just got my miner (from group buy #6) up and running a while ago. I don't know if it's a typo or if something has changed, but the Ethernet port on the router is its WAN interface, not a LAN interface. I needed to switch the WAN interface over to DHCP to get it to play nice with my home network. Other than that, it was pretty straightforward. Power is from a Corsair CX600M; the Kill-a-Watt says the rig is pulling about 400W, and the miner status page says it's doing about 179 GH/s.
It looks like cgminer's API port is only listening on localhost. I'd like it to listen on the WAN port so the stats script I have on another box can see how it's running. Where would this be configured? I've not dug too deeply into the software just yet.
I'm using the exact same PSU for 200GH/400MHz setting, using 4 wires per blade (ie: 14pin ATX mobo connector each) GENERAL QUESTION: what pools and settings do people use? ghash.io has become dangerously large and I have moved my 600Gh of mining to eligius to do my small part.

worth putting here:
I took my new S1 unit (with PCI sockets) and a PSU with 630W available on the 12V line
at 400MHz its running a little over 202GH and 46-49C
at 425MHz it still falls to ~191GH
it seems the cooling is not the issue, and the issue cant be the regulators (that would act differently) - The chips simply need more voltage in order to achieve this clockrate.
anyone familiar enough with the TPS53355 or the antminer schematics to identify how this could be achieved? I imagine a pencil mod similar to with the bitfury ystem could be used to slightly increase to 1.20V and allow the unit to push past 210GHash
According to Bitmain, you will need to change the resistor for higher voltage. https://bitcointalk.org/index.php?topic=330665.msg3580902#msg3580902of course. however, the question is an issue of what the actual PCB schemativc is. if the R1 and R2 (if there is an R2) values for the TPS53355 are identified, a pencil mod would not be very difficult |

Okay, so I logged in with SSH via putty and gained access as root.
How do I edit /etc/config/asic-freq ?
It says permission denied.
'vi /etc/config/asic-freq' |
