just contacted by the seller - will post progress as I am still waiting for the prize

you could be doing a bit better. 6 H-boards with some small pencil modding can give you ~34*6= 204GH + 197GH for an antminer running at 387.5Mhz = 401GH

its worth squeezing a little more out while the difficulty is low

good luck. when they shafted me three days in a row by not putting it for pickup and instead sending it for delivery attempts that never take/took place (9:45pm? seriously) on some of the first auctions they did not care one ounce.

you would need to order today i imagine. the 25th in china is basically friday night in north america

calm down. re-quoting yourself a dozen times adds absolutely no value to your complaint. none at all - in fact some people put you on ignore now.

I would no be surprised if the UPS told bitmain they would/did try to reach you. Ive had several experiences where they say they will call back within an hour and a day goes by without a call.

Bitmain just gave me 2 tracking numbers for packages that should deliver today. no word on the third tracking number, but i was told the package should be with the others (still waiting on the number though to make tracking/pickup easier). screaming for a refund is probably not a realistic request if the packages are already halfway to you, but you just dont have a tracking #

so what is the problem? It sounds like the antminer is powered on and you can access it...

As this project begins to seem clearer in my eyes - it appears two distinct sides must arise: miner colocation ('collective') services for hosting the equipment of existing miners; and a mining farm backed by a few investors with clearly set out contracts for agreement on sunk costs (initial equipment like racks and networking), equipment type, location, and defining the 'profitable lifetime' for equipment (based on the ratio of [mining income]/[power/rent/upkeep costs]).

With asic power requirements rising i think there could soon be an opportunity to have very profitable machines as long as you can supply enough power to them - and in my mind making the commitment to a larger facility makes more sense considering that >20kW will soon be a minimum necessity for larger mining clusters or 3kW KNC devices

In my mind, I hope to have a few locations scouted out by mid-february, and actually start a rental contract for March 1st - by which point 6BTC/Terrahash/kW will be the market price for 28nm and 4BTC/Terrahash/2kW for 55nm. With a few investors it could be quite profitable to control a 10-25 Terrahash mine with clearly defined agreements on equipment type, monthly costs  including power, and some definition of the anticipated lifespan for profitable operation and/or re-sales. (I can tell you that there is a large local market that will pay 30-50% over market price for in-hand ASICs)

If a commercial power rate can be negotiated, it could allow hosting options (including power) to be competitively priced in comparison with mining-at-home on residential rates

I am still looking for input- everytime a question is asked, a suggestion is made, or someone looking to be involved reaches out- the project becomes a little closer to a reality

they are paid 20% for 20% of the pool's hashrate. without them your income would be the same but with higher varience

exactly   its for the antminers prior to pci ports. with the ports, using pci for one blade and the atx mobo tips in the picture for the other is perfect

I have the same hub - 3.5A runs 5 antminers at 1.8GH each.
just added a 6th and am testing with 2.0GH - seems like it wont work though as only 3 detect and the rest throw port detection errors

snip theheads off the 4-pin ATX mobo cables. I ran an overclocked antminer using 2 pairs of 12V line from the ATX for each blade (wires did get a bit warm but not dangerously). Using just a sinlge PCI-e for both blades will be a problem and danger though

bad idea - 400W on a single pci-e plug may cause fires and melting on some cheap PSUs

snip the 4-pin head off the ATX mobo plug and you will have 2 more pairs of 12V wire to use

yeah that likely wouldnt be an issue. It would take at least 20TH of equipment for a private pool to make much sense, likely far more

I will be at the Toronto Bitcoin meetup tonight to try and network if anyone here is looking to connect

how are the antminers sitting on that metal rack? is the 'frame' placed right on the rak rails, or do the PCBs suport the weight (and not ground out) on the metal bars?

i have paperclips and short 3mm lengths of wire if anyone wants them!

3 orders (2014-01-19 21:05:45,   2014-01-19 19:51:42,   2014-01-19 15:35:07) have no shipping cponfirmation yet. Im hoping bitmain has them in the mail and just hasnt yet passed on the tracking info (in the past, i often got the info 12hrs after the boxes were received by UPS, if not already out of the country)

crossing my fingers they come this week, but without a tracking number soon I just dont know

I get 45-48 at stock speeds on some units and 43-46 on others. I generally overclock to whatever speed keeps the temps in the 50-53 range (387 or 400 on most units)

so because one brand thats not the topic of this thread made a profit, a $30,000 loss is negligible?

fools and thier money

They use 12V DC - so you need some power converter/supply. Server PSUs can provide lots of efficient 12V power for cheap. $5 for a 835W PSU, $10 of wire/solder/heatshrink, 30minutes of my time, and I have 835W over fat 14AWG cables meaning only one wire pair per blade

seriously, go fuck yourself. you should not receive a bitcent of that payout considering the garbage you've filled this thread with over the past 3 days
