i didn't make it up, but you're totally right.. people don't seem to complain when they've bought inefficient old chips, as new. but you're absolutely right, people seem happy with buying AM's old stock 'as new'.

Please show me a single person who complained about receiving used hardware.

I've seen people in these forums praising AM to the stars for shipping 'excellent' products that consumed for some reason significantly more power than any other system available by a large margin, and calling them rock solid and fantastic systems. even those that consumed multiple watts per gigahash.

How many asics were less than 10w/gh before june?

Do the specs really matter when every single person who bought from AM turned a profit in USD and many even in BTC?

(promised to be 0.35 watts/GH in the spec, and ended up consuming a lot more).

Please stop saying it was promised because that's just not true. It was an estimation and as we all know estimations are wrong.

ok, so maybe promised is the wrong word. All power and performance specs that are stated in advance are an estimation based on simulation using asic design cad tools and data provided by the fab.

whether it was promised, or estimated isn't of issue. Just as much as any other asic company can predict in advance its performance and power consumption, so can asicminer, and to be honest, so did everyone else. we shouldn't be holding asicminer to any standard thats different from any other asic company. they suffered pretty much the same fate that others have done before them and will no doubt do after them.

read the spec that asicminer posted on their first post... it doesn't say estimated anywhere. it doesn't leave much room for doubt. it says what they expected the spec to be, and the reality, when the chips arrived back, was far from the expectation - perhaps as much as DOUBLE the power consumption of what they expected. Not, that any other asic company got it any more right. BitFury expected their chip to hash at 5 GH and even labelled it on the top and the chip can do approx 2.5 GH. Cointerra expected their system to be 2 TH (using four 500 GH chips) and it ended up 1.6 TH (four 400 GH chips). Spondoolies has also pre-warned us a few days ago that we should expect their spec will not fully live up to their expectations, etc. in short, its not uncommon for asic companies to say what their expected performance and power requirements are, in advance - with their best will and best intentions - and when the reality sets in (after the chips arrive) then they have to announce what it actually is, rather than what it was predicted to be, and there's often a disconnect.

anyway, the first post in their thread shows what asicminer expected their perf/power of their chip to be...
