Hello fellow bitcoiners, Since BFL singles are flying out all over the world to eagerly awaiting purchasers, I wanted to start a thread to find and list the best settings to use with the single. So if you have a single and have tested some settings, share them! Thanks, gigavps * Looks at Fred0  |

I would never let girlfriend/wife interfere with my business investments, if i see something is going to bring X % ROI annually, all she'd need to know is that it's going to bring the bacon on table. Lots of american men are pussies when it comes to their women. The men bring in all the money yet still let their bitches tell them what to do with the money. Can you believe that? American women are spoiled cunts. On another note, my wife knows all about the mining adventure and has approved ever since she saw the first $1k hit the bank account. She even put up with the house being 86 degrees when there was 5Gh running here. on that same note, i was giving my wife a quick overview of bitcoin, and told her i was going to be investing in it. she still had the glazed over look in her eyes from the bitcoin explanation, but she didn't miss a beat with the, "i trust you to do whatever it is you think you should do." Good woman you got there. Mine did the same until the bank account bloated up a bit. |

They also want me to come out make threats so they can report me/sue me and have me hurt again.
The only thing that hurts is my eyes from reading what you have so say. |

Rig box should get 20Mh/w and was priced (when I bought them) at $25k each. That's $0.50/Mh which is pretty darn good unless you are really bargain hunting for GPUs and the other items needed to run them.
How can you tell that rig boxes will get 50GH and use 2.5kW? I wouldn't be surprised if it turned the same as with singles (1.05GH, 19W if I remember right..). Of course I hope this time they will go along a different route, I might buy one myself then (once I raise enough money ofc, $30k, even 25, is a bit steep). BFL has already adjusted their original estimates on the Rig box based on their finding from the single and are quite confident this time around. |

I have 2 issues I am trying to figure out...
1.they guys making the fpga's can sell them, but for every one they sell, they keep one, and mine with it, eventually drowning us all out.
2.the reasons you give for guys with gpu's dropping out will eventually be the same reasons you guys drop out, your buying the least efficiant fpga.
The jump from CPU to GPU along with a huge price spike will be quite hard to replicate IMHO. Bringing on 1Th of FPGA/sASIC equipment will not raise the difficulty significantly and will take quite a while. It will take something like a custom ASCI chip sold in mass to duplicate the jump in difficulty we had from CPU to GPU. As for buying the least efficient FPGA, I believe it is the jump from GPU to FPGA which matters most to my bottom line. A rig box, as proposed, is so much more efficient than my GPUs that it will pay for it's electricity costs in 1 day of mining whereas it takes my GPUs 15 days to pay for the electricity they use. If I tried to purchase equipment that was twice as efficient as the rig box, it would pay for the electricity in 1/2 day. This is a diminishing return and not the only thing to consider as I would like to make my original investment back. |

ok....why will miners quit?
Mining will become unprofitable. |

whats the reasoning you guys are using to buy these instead of ICARUS fpga's.
just curious.
Rig box should get 20Mh/w and was priced (when I bought them) at $25k each. That's $0.50/Mh which is pretty darn good unless you are really bargain hunting for GPUs and the other items needed to run them. When the subsidy halves, we will see a lot of GPU miner become unprofitable with 2Mh/w to 5Mh/w unless the price rises substantially. I doubt the price will jump like this in lock step with the halving (I've been wrong before) so we should see the same thing we saw when the price went to $2. Miners will quit. |

Lol as far as I know they arent sending out any!
You guys are kind of ridiculous. I know a guy with a 30Gh mining farm who doesn't have an account on the forums. Why do you assume that if 100 people don't all post at once that no one is getting singles? With all due respect, I think it was YOU who said that their first batch is entirely sold out (and, by implication, now they have to wait till they receive batch #2 from China). So, if someone draws the conclusion that for the next few weeks, no one is getting singles, I cannot blame them, because I arrived at the very same conclusion (without publicly crying a river, however). Hi Inspector 2211, If you look back I edited my post to say "Rig Boxes" and not singles. That was my fault. Best, gigavps |

These FPGA boxes are cool, but has anyone here considered the impact to their mining business when the mining reward is cut in half? That's happening later this year at current mining rates. At that point if you're currently making say 1 BTC/day, you'd suddenly be making 0.5 BTC/day for the same hash rate. See https://bitcointalk.org/index.php?topic=67387.0Hmmmm. Maybe you should think some more about this before posting. I could be wrong, but the WHOLE POINT of more efficient miners is to be able to make money when events like the halving of the subsidy happen. Just a thought though. |

can you use pocblm gui with the singles?
No. cgminer or ufasoft. I would recommend cgminer. |

WHAT SICK MAN SENDS BABIES TO FIGHT ME
*om nom nom*
It's cold on that lower rack. Best place for the most highest hashers with lowest power draw to be. |

The only reason why we haven't banned him yet is because we find him amusing. Well, that and a lot of interesting facts about shakura have come our way.
I would rather have peace than be amused. Hey, no depriving us of our entertainment  Well, now that I have figured out how to ignore PMs from this idiot, you may continue to verbally harass and abuse him to your hearts delight. |

I am definitely ready to start this up again! LET ME IN ALREADY!!!!!!!!!!!!!!!!!!!!! |

forrestv or meni likely could provide a more mathematical analysis, however anecdotally even a change in intensity from 9 to 8 on a 5970s (0.05 sec to 0.025 sec) shows improvement in stale rates (~7% vs ~3%). I could try increasing intensity to 10 (2^25 hashes) to see how much worse that becomes.
That being said I would imagine it would be a case of diminishing returns. i.e. 0.5 sec is 80% better than 5s but 0.1 sec is only 90% better and 0.05 is only 95% better, etc. Average LP interval is 10 sec so unless results can be returned in <0.5 sec it likely isn't worth modifying. 1 sec may be better than 5 sec but both are likely so bad as to be ineffective.
Maybe I am wrong, but isn't it always a good idea to return work as it is found even if you are not mining on p2pool? This way if a long poll happens in the middle of the BFL single processing work it could have already returned proper hashes for submission to the pool? |

Kano (others?) is there any possibility of a miner change to make Bitforce more compatible with p2pool? I personally have little desire to mine with the large pools again and am taking loooong looks at this platform as my next upgrade/purchase.
My understanding is that it would require a firmware/bitstream change on the BFL Single and since BFL hasn't opened up the bitstream source and/or provided any details on the chip used that will require BFL releasing a new one. The issue is that BFL single processes an entire nonce-range (2^32 nonces) in one big "chunk" before providing any results. 2^32 / 800 MH/s = ~5.4 seconds. With LP interval of 10 seconds you will have roughly half the hashes stale between the time they are found and the time the Single finishes the nonce range. GPU work in smaller "chunks" and finish one chunk in a fraction of a second. How long depends on intensity and even too high of an intensity (9 in cgminer on a 5970 is an interval of 0.0105 sec) can cause a high stale rate. The single is working on an "intensity" 500x as high. Making BFL single compatible w/ p2pool is possible but it would require the single to handle work completion differently. There are a couple of options but they all involved internal changes to how the single processes and reports found hashes. As it stands right now there is nothing Kano or any other miner developer can do. @BFL-Engineer: Has this been brought to your attention and are you working on a solution? |

I stand corrected.  |
