BA cards? BlackArrow perhaps? Yeah I see they're a bit cheaper, but the question is how reliable are they. Sad that they still use chainminer in rasp pi image they distribute. Chainminer is junk.

I use chainminer, mainly because I have no choice. I tried bfgminer (admittedly not cgminer yet) but due to the necessity of individually tuning the chips and bfgminer's poor auto-tuning feature I abandoned it.

A successful bitfur driver would have to allow for the manual tuning of individual chips. It is sometimes necessary to completely turn off a chip or a few chips in order for the rest in the chain to perform optimally or at least normally. The way chainminer does it (with a user editable table) seems logical.

Does cgminer even support these bitfury boards running on the rasp pi? I see a bitfury driver in the latest 4.0 release but I'm not sure if that driver handles these h-cards or if it's meant to handle only bitburner boards or usb bitfury miners.

Kano, if you want someone to test out any changes to Cgminer on bitfury setup fully populated (16 cards), I would gladly do that.

1.2 H cards.  The card # 5 is a more recent one.

Maybe too high for here, as others have pointed out this stuff sells much higher on ebay.   Below a certain point it makes sense just to mine with it.  Difficulty increase has slowed and these are quite power efficient. 

True, but typically it's the noobs that buy on ebay and bitfury gear (especially v1.2 hcards) are not noob friendly at all. They are finicky and sometimes unreliable with often constant maintenance required. Maybe you'd be just better off mining with it until it's "worthless." Having said that, if you have no luck selling it here or on ebay, I'll take it for a little over $400 which is what is required to at least break even in 2 months.

You could get 768G if you bought 256 rev2 bitfury chips and paid for 3rd party fab/assembly for 3k ballpark

Yeah I am not touching that stuff either. I am not only concerned about the legitimacy of the product, but also the quality of the assembly and components. A cheap miner is fine but one that fails within the first month is as good as useless.

ARRRGGHH!!  I dislike the word fair!
