Just a quick note catfish, so that you are aware - these devices have their own microcontroller and flash, and come preloaded with "a" bitstream, but as you well know cannot be updated to a faster version outside of Windows. But they don't need to be reprogrammed each powercycle, since the firmware/bitstream is stored locally.
However, making it updateable within a *nix OS is definitely preferable, even if the bitstream remains encrypted all the way to the device. That would make it much better.

Which of these is the most profitable?
Here is a quick comparison of various offerings that DiabloD3 whipped up. You may wish to do some research on each device before potentially getting stuck with something you don't want or like for some reason; https://bitcointalk.org/index.php?topic=77469.msg887606#msg887606BFL's mini-rig looks to be the most profitable and efficient of the FPGA options, but hasn't shipped yet. The X6500 is the most efficient, but is a bit expensive per mhash/s so has a longer payback period as well as limited availability. If you get in on the cheap pre-order price, the Enterpoint quads are a good bet, and they should ship within a few weeks, but don't have final software support (yet). The BFL Single is the least efficient outside of GPU mining, but also relatively cheap and fast. Various ASIC based solutions have not shipped yet, and command a premium because of their novelty and efficiency. Reference Largecoin, and possibly SHAlab. The BFL single looks like my best bet. Where do I get them, and what setup do they require? You may wish to do some research on each device before potentially getting stuck with something you don't want or like for some reason;
Butterflylabs.com Each of the options I pointed up has a minimum of one thread on this forum devoted to it and I would recommend that you read them. This is a link to the FPGA sub-forum: https://bitcointalk.org/index.php?board=76.0 |

I see that too on W7 x64, and additionally another display anomaly: Clicking the icon once pops the window into the foreground, and clicking again puts it back down in the tray. This isn't a bad thing, but it is different from how it used to work. It used to require a double click to open, and X it out to minimize to tray.

since a TPB link isn't ideal to ever post anywhere  Not sure why not, but I edited my post accordingly. Unfortunately Mr. B can't edit it out. Haha so that's what you are calling me. Mr. B epic too bad my posts can't be edited. TPB link is banned in most western countries like the Uk. Yeah, the oppressive governments with communistic tendencies. And that law was passed by a corrupt judge. Fuck them. |

The whole "second hand chips" thing is mind boggling. Mem's lies not withstanding, I have seen their chip shipments first hand (and hefted a 500 ct package of them) - if they are second hand, they are fine quality second hand goods. The whole second hand chip thing is a baseless claim. If anyone with more than a passing familiarity with the industry thought hard about it for more than a few minutes, it's fairly obvious how they acquire their chips.
SO you DO work for BFL then ? Might be wise to state a disclaimer when you promote them so fervently ! No he's just the parcelboy that ran off with one of their shipments.  Grow up dude, and quit trying to make yourself look stupid. |

I laugh in the face of all those thinking BFL is legit. Second hand chips, lies, deception ... what more do you need ? Just wait till the orders stop coming in and they pack for Barbados !  I laugh in your face at all your contradicting statements. You can't seem to decide whether you are for or against them. Reference the following quote, and compare it with the one above: Why do you consider BFL as being "shady"  I really don't understand. They have 10 years experience in FPGAs too. Only disadvantage is high UK VAT import duty cost ... Get your shit together, man. |

Basically everyone sells for paypal, because of a nonexistant risk of getting scammed.
If you're in Europe though, you can't easily send money from your online bank account to any other person in Europe, because it costs so much (so that's more expensive than paypal).. If you're interested, send BTCurious message.

Out of curiosity what is the absolute highest hashrate you've gotten out of these units? Now if someone was to build a waterblock for the babies we could push them to the edge 960 MH/s has been confirmed, although the unit throttles every 40 seconds. Running at that speed needs special cooling (it may work in the freezer however, without throttling). Regards, BF Labs Inc. BFL recommends putting your singles in the freezer!!! lol, that's only with an unreleased test firmware. Although it would be fun to try. |

I c wat u did thar, trying to get the top post errytime. EDIT: Now I'm on top shiet |

Hmm. I wonder if I can slide in a comment disguised as another thread?

Doesn't anyone have a farm optimized to run Vanitygen yet? They could sell their services. For optimizations, you just need to overclock and make sure your memory is clocked up as well. It should run very fast on a 7970.

I just want a working unit, I'll handle the bird training Well I guess what he is pointing out is that the machine is supposed to handle the training, and that part of it might be annoying to create. However, an easy one would be to just make the machine work on step 4. Or maybe the machine could handle all 4 modes, but would require manual intervention to switch between modes? |

Meni Rosenfeld did a writeup on how you could balance your hash across pools and reduce your variance. But I'm not sure I would bother with only 1 Single. You should of course have failover pools, so that if the main one goes down you can back up to a secondary or tertiary server.

Could you make a webpage to generate a cgminer config file? I could make it, but it'd be in excel or something. I'm only good with VB lol.
That would be really cool. Maybe like an easy to read set of forms, or a wizard perhaps. |

Not this again. Just let this thread die.
