Why the increase to 2.65? 2.4 is where it should be right now... possibly lower for previous customers.
Because people are buying them. As buzdave is saying it is demand and supply. The only one to be blamed is US we are the demand. This was th best deal, but at 2.65 it will never pay out. good Luck to everybody. |

I am jealous because this fans are not on mine  You won't be after you catch your finger on one. One slight touch and it's slice-slice! Picture don't show it well but it put 2 slices in the end of my little finger.  It wAs not pleasant experience for sure. You should be more careful next time But any way I still do want them badly |

I hear the rumor is 1W/GH and 40GH per chip. (similar to Black Arrows numbers) This looks like it's gonna be 8x 40GH = 320GH/320W If this is true and you have Hex16B on order 28nm only looks to be around 40% more efficient. 1w/1g will be the case up to 20gh I think Power usage* of 0.35 W/GH in low power, 0.6 W/GH in nominal and 1 W/GH in Turbo mode. turbo mode is 40ghash per chip. buy specs We will know exact numbers soon. But i do not trust specs completely. besides for the wall power draw we shall add at least 10% for dc/dc losses + 15-20% PSU loss if turbo specs is correct it will be at least 1.3W at the wall i do expect about 1.8  |

I just removed a fan and holly crap the fans on my second shipment are 4.7W 4500RPM 75CFM 47dBA!!! http://www.alliedelec.com/search/productdetail.aspx?SKU=70226025#tab=specsThey were only 2W 3000RPM 51CFM 34dBA Sunons on my last Hex16B. Seriously these fans are dangerous at 4500RPM without a guard. Watch out for your fingers! Noisy as hell too. UPDATE: Just set all the 4500RPM fans to 5v. They probably still do 1875 RPM 31CFM. Seem to be keeping things cool enough for now. Got some Arctic F9 on order, just the regular 1800RPM 43CFM ones without temp control, cheap as chips. I am jealous because this fans are not on mine |

Just info: currently available patch afe7710858e4ce28bb60f6ae6e167a18d687634f.patch is for cgminer3.8.5, will not working with cgminer3.10.0. Soon it will + some nano optimisation |

oh... so you are just dumb. Obviously not, instead of you. Simple math: Bough for 2.4BTC and earn MAYBE in 280 days 25% <> compared to exchange 2.4BTC and hold for 280 days. A simple RISK calculation. As i wrote is not rocket science, maybe i was wrong. For someone it is. The risk to lose money (Fiat) with buy BTC and hold instead of lose money (Fiat) with buy a miner and can't calculate the difficulty clearly. You get it now? If not, never mind. i have time... okay, here we go: SITUATION 1: BUY NOW 2.4BTC bought at current exchange rate and held for 1year -----> 2.4BTC as of Jan 11, 2015 2.4BTC bought at current rate and used to pay for antminer -------> ~2.4-3.0BTC as of Jan 11,2015 (the antminer probably is turned off before september though) SITUATION 2: BUY LATER 2.4BTC bought at current exchange rate and held for 1year -----> 2.4BTC as of Jan 11, 2015 or (assume BTC=$1000 right now for simplicity): In 1 year, buy $2400 worth of BTC -------> *unknown amount* as of Jan 11, 2015 (my guess is you will only get about 0.5BTC at that time for your $2400) I'm still not sure why you say that holding will make more, or gain some sort of 'interest'. its easy to estimate how many BTCs mining will produce, and that calculation appears to show it will produce more than its own cost. there is some risk involved because of 'sunk funds' if you had to ever transfer BTC/USD before making back the full miner's BTC price, but you also get a valuable (or maybe just 'collectible') piece of hardware with resale value Please show me what i am missing, because it seems that if a mining device has a good chance of returning 125% BTC of what you paid for it in BTC, that is more then you would get by simply having a cold storage wallet with the same initial BTC in it +1 on that but when I see some reasonable deal (smell like sell off) from china (no irony) here I expect a big technology jump and diff raise of which we are unaware That is why I prefer to sit on my btc as long as it takes and waait for a day when producing ASIC chip will not pay off. Then diff will settle so we can spend again for mining hw The good news is that china new year is nocking at the door so we will probably take a breath with lower diff jumps during china holidays |

I have two miner and already prepared to molex adapter - one for each miner.
Is it safe to just plug them in?
The question about the black was: Which black should I shortcut to the green one as there are 7 black cables.
It does not matter whichever you like. They all go into one place inside psu Make sure you use separate wiresto plug molex into. As gator advise be sure to spread the load |

Ok, so it has to be a PSU. hmm X_X I have a spare Xilence 550W. Unfortunately it has 7 black cables and 1 green one. The label looks like this.  I am counting 9 fields per row (2 rows) The connector to the mainboard hat 10 connectors per row (2 rows) How do I identify the correct black cable? Every black is correct. How many boards do you have. If one just use two blacks from PCI-e and two yellows It is not single rail as gator ( he is a pro also) advise so be careful. |

Best option would be to use any cheap psu with green and black shortcuted.
(...)
Thank you for the reply a) What do you mean by "green and black shortcuted" b) How would I actually power-on the PSU? That is exactly what I mean  You need to shortcut green wire with black wire on 24 pin mother board connector otherwise it will not start And additional advise make your wire connections tight otherwise they can melt http://m.youtube.com/watch?v=6xLy8rZRjU8&desktop_uri=%2Fwatch%3Fv%3D6xLy8rZRjU8They melt because you load too much power onto one wire. Try to spread the load out to as many wires as you can. Never take the PSU to it's max box wattage, some of its watts are for the 5v and motherboard. Try an get single power rail PSU if you can as that helps avoid some loading issues as well. I know dude, but they also melt when molex is crapy with bad pin contact or you are in a hurry and just spike two wires and tape them That was I what I tried to explain S |

Pci-e wires are thicker |

Hi mtbitcoin, we do want to setup an evaluating program in near future. Since you are the 1st senior member of the forum asking for evaluation, we will ship you one unit to perform your independent evaluation once we receive our batch shipments.
As to your question of timeline, we are expect to receive our 1st batch of 50 units either next week or week after next.
Super! Any info about bulk chip orders? I am interested. 10X |

Congrats BITMAIN!
This is the only offer from ASIC vendor (chip producer) which can make ROI. Other ASIC vendors shall learn from you. I wished our communication over PM about chips to be continued in same manner. But unfortunately after initial pm exchanged almost a month ago you never responded.
Good luck
Once again Congrats for the reasonable price even for limited quantity

This has been removed in latest builds. However all you need can be found under cgminer-api-log via web interface Best |

I also had a few crashes - core dump. Maybe because of weird system. Try to figure out on weekend.
System load seemed much lower with the version of main.
This is due to nonce checking. For sure Con version is doing it faster. I am sure that in new technoit release this will be tweaked also |
