Do BitFury rigs overclock well? Is it reasonable to expect 500 GH? Are they reliable? I read a good number of horror stories on this thread from folks who had a lot of trouble getting all 16 boards to work correctly due to board wobble and poor connections. Does the SD card still get corrupted when the machine is powered off?
Do not expect more than 400. The systems are quite stable, but there is a lot of variance in each card's performance.

My v1 m-board/h-cards are running at 505gh/s. I'm not sure if I was just lucky or not though so I would base all ROI on 400gh/s just to be safe. A lot of people posted about corrupted SD cards, but I have not ever had this problem either. I have lost power 2 times (once my house almost burnt down... damn power line falling and starting neighbors shed on fire) since I had this v1 bitfury and my SD card handled it like a champ. Same with my other SD card on my RPi for other mining devices. Knocks on wood that they keep lasting like champs and that no more power lines fall close to my house and start stuff on fire

Yes, yes (510-515), and yes. To prevent wobble order a really nice case from spotswood: https://bitcointalk.org/index.php?topic=267713.0The newer kits have the v3 m-board with newer chain miner software, which includes a proper shutdown button on the web interface. Otherwise ssh into the device and issue a 'sudo halt' to cleanly shutdown the RPi. No corruption.

V1 H boards, V2 M board Ordered an 8 board miner yesterday and it's being delivered tomorrow. That's how the world is suppose to work!

I have had mine going at 620 stable for weeks now. The cards are good they just need some attention to get them happy.

0.47BTC H-Card, time to buy  This...the price drop is appreciated. Cheaper (by about a third) than AntMiner, and more power-efficient. Please explain how you arrive at this conclusion. Bitfury 200GH set is $3200 = 3.9 BTC at current coinbase $822/btc Antminer 180GH is 3 BTCBoth shipping now. How is bitfury 1/3 cheaper than antminer? Bitfury is more power efficient - that is understood, but i dont understand why you think bitfury is 1/3 cheaper. New price is actually 2.65 it says $3200 for 200GH, am i not looking at the correct website? http://megabigpower.com/shop/index.php?route=product/product&product_id=69A Bitfury 200GHs kit easily does 240GHs without doing any overclocking of your own... the cards come out of the box doing 30GHs+. Also, Antminers are not currently for sale from stock. And wasn't the 2.65BTC price just an introductory offer from the new BitMain website and limited to only the first 30 units sold? Why does Crypsty kick it's customers out of the site several times a day?
Wow, this couldn't be more off-topic! Lol.

Some advice for the new Bitfury virgins...
- always power-off your rigs by "sudo shutdown now -h". I haven't had a corrupted SD card since I started doing this.
- buy extra high-quality 8GB SD cards and pre-burn backup card images... just to be safe. I had terrible luck with the cheap-ass 4GB SD cards that MBP use to supply with their rigs.
- get an extra rPi. I had two die. They're absolute crap!
- buy 2 half rigs (or even 4 quarter rigs) instead of 1 full rig... for two reasons. One, it's nearly impossible to get a 16 board rig to run stable. Two, you'll want to have an extra M board (or two) on hand.
- keep your rigs cool and well ventilated. Some guys use a bunch of heat sinks. I just use 120mm or 140mm PC fans and cool the boards push-pull style.
- H boards need to be stabilized in some way or else they drop offline or cause errors if they wiggle or vibrate. Some stick packing peanuts between the boards. I run two strips of electrical tape across the top of the boards. Spotswood's custom cases also have stabilizing devices included. I have one but haven't assembled it yet, lol.
- stay away from cheap and/or under-powered PSUs. With PSUs, you really do get what you pay for.

No, first 30 units were priced at 2.40. At current price and BTC/USD ratio, a full rig will not break-even. spiccioli

I've pulled updates a few times since first setting it up; it says it's now at 3.8.1. It also has a Klondike K16 slaved off it in addition to a couple of Jalapeños.

Bitfury is more power efficient - that is understood, but i dont understand why you think bitfury is 1/3 cheaper. Four H-boards will do 140 GH/s with mild overclocking (the two I already have are doing 70). I paid about BTC1.87 yesterday for them. Five (for 175 GH/s) would've been about BTC2.34. "1/3 cheaper" may have been a little bit of an overstatement, but Bitfury hardware is now cheaper. Until recently, it wasn't; that's why I also have an AntMiner. I'll build out my mine with whatever will give me the most bang for the buck for what I have available to spend. One other thing I noticed: the 4-, 8-, and 16-board kits appear to now be shipping with M-boards at no additional cost (though without the Raspberry Pi and SD card). That's a nice change from when I bought my kit, where the M-board (and RPi and SD card) added $800 to the cost. Allowing $40 for a RPi and $10 for an SD card, there's no way there's $750 worth of parts in an M-board.

If I had heeded that advice I wouldn't currently have 2THs of mining gear with another 4THs+ preordered mining gear. All of this has been paid for (with the exception of the first 200GHs or so) from the BTC I mined. And I still have approximately $20,000 worth of BTC left in my wallet. And no, I wouldn't have even more if I had bought and held BTC instead. I tried doing that and I failed miserably. Like most people, I panicked at the first dip and lost a good chunk of my modest investment, lol. "Buy and hold" isn't in my nature. I'm a miner and proud!

Me too, but this is not changing current statement. My point of view is if i spent x BTC for minig gear i should be able to make x+y btc in near feature. In current situation it turns out that you will be making x-Y btc and Y will be about half of the X btc invested. Near feature means infinity! Are you getting the idea now?

I honestly have no idea what you're saying. I'll just keep mining BTC and buying more gear. And when I've had enough, I'll sell my ASICs for even more profit. But thanks for trying!
