Don't use hashfast. They're just another US based scam company using fairy tale delivery dates to sucker people into dramatically overpaying.

Are you able to price products in BTC Dave? Your service is light years ahead of the competition. You guys say you're shipping and the fedex dood is knocking on the door next day , but the current exchange rate makes your products tough to take. H cards were right around .42BTC last time I bought, but they're now around .53BTC with higher difficulty. It's a bummer.  

Load balance works fine on chainminer. I haven't checked the cpu load on the wimpy raspies since adding more pools, but they seem to be holding up fine with a modest overclock. Bitminter has been going down recently and the idle hashes were sent to the other two pools like clockwork. 

HW errors are not included(noncerate vs hashrate). The reject rate hovers around .03% on bitminter so I doubt it's much of a factor either. Hashrate gyrates between 4900ish and 5400ish according to bitminter with 138 cards, a little over half of which are modded(voltage & aluminum). BtcGuild seems to be spitting out very similar numbers now, though the cards initially had stability trouble there. I dunno if a proxy update patched up the trouble or what, but they work fine on BtcGuild now.

Listen, I'm not looking to be the bitfury spokesperson, I think the gear is horribly overpriced at this point. They should at least come with heatsinks at these prices, but they are fun to tinker with and you can finesse a decent hashrate from them with some patience. Well lots of patience. It's not a very polished product to be sure.

Love cgminer btw, so thank you.

They're capable of 40+ with some coaxing.
