You only (potentially) need this if you are using 2 PSUs on one machine. The PSU thats only powering GPUs is only loaded on the 12v rail, which can be a problem. I assume you are using only 1 PSU, so you are powering the motherboard with it; in that case, there is no point in wiring light bulbs or resistors.
I am using 2 PSUs on one mobo and I need to load up the 5V line to put some stress on the PSU that is only delivering through the 12V line etc. |

Sorry to bring up this old topic but the resistance is 10 ohms.
They are 10W 10 ohm ceramic resistors.
The PSU is a Corsair AX1200 with 30A on the 5V line as far as I can see.
What is the amount of resistors needed and the wiring ( series or parallel ) ?
Thank you !

Gents, I'm going to fall on my sword I think and order a couple of these. Not sure if anyone else here has a standing order, but regardless you can use me as a test case to follow from preorder, to delivery, to product testing.
...
Again, you no doubt think I'm an idiot, but that's not your problem, and I don't need to hear it. I'll post again once I've ordered.
FWIW, I don't think you are an idiot. You've obviously weighed your options and have reached a valid conclusion for your situation. I would be very interested to follow your test case. Please keep us informed. I believe gigasvps has also posted that he has placed an order and would let us know his experiences. Haven't heard from him since, though, but honestly I doubt there will be anything to report until BFL actually starts shipping. True enough, and I'll definitely keep everyone well informed. Thank you for stepping up like this and keeping us in touch. Just what we needed right now ! |

I'm worried about running my video card at full for long periods of time because I don't have any kind of cooling other than the chasis fan and the fan in the card itself. When I run the ocl version, it gives me a timeframe until the probability approaches 100%.
My question is, can I run it for a bit, then quit and run it later, or will it re-find the same old tries? Do I need to let it run until it finds it, or can I for example close it at 1% and then just look for 1% each day until I find it?
Sorry if this is a stupid question. I understand what probability means and that it's just brute force guessing, but the fact that it gives me a time frame makes me wonder if it has a certain starting seed, which would mean re-starting it over and over, doing a little each day, would not be effective in finding a solution.
So, do I need to run it all the way through or can I just do a little bit each day?
Interested in this too. Hope we get a comprehensive answer. |

OK. How about Electrine ?

NEWS: Fee to be re-introduced
How are you enjoying mining with ABCPool so far? It's thanks to you, our loyal miners that we have got this far! Without your constructive input, your kind words and of course your hashpower we would probably not have been here anymore.
As you may have seen on the account details page, running a pool is not free.
When ABCPool just started out 5 months ago, there was an introductory fee of 2% for a short time. ABCPool was not always stable in the early months, and we did not feel justified to charge you at that point. Therefore we soon lowered the fee to 0% and paid server costs, stale shares and invalid blocks completely out of our own pockets. Now that ABCPool has proven to provide a solid mining experience we feel that the moment has come to re-introduce a fee, 4%, sometime in the first week of 2012.
Charging a fee is necessary to keep on providing you with the service quality you have come to expect from us. Any pool that does not charge a fee will eventually disappear, because it will inevitably cost the ops money. Many of you already donate 2%-4%. With the new scheme, you don't have to worry about others not paying for their part, because other users will pay the same..
The fee will enable us to pay for the server hosting, motivates us to keep on improving ABCPool, and helps to offset the risk we take by offering PPS rewards.
From your perspective, you might consider the fee to be a 'risk premium': by being payed per share you know exactly what you'll earn every day. How much is that worth to you? In addition we shield you from invalid blocks and stale shares.
In the new year we will continue to provide the best service we can, to ensure that you'll continue to enjoy mining at ABCPool!
Happy hashing,
MC & Chlorine
Please modify the thread title so as to not confuse users now there is a fee. Thanks ! |

I am very concerned that this service serves NO legitimate purpose except enabling people to purchase attacks against bitcoin.
Asking on IRC about it on I'm told:
< pirateat40> gmaxwell, you can't blame someone for building a way to do it.
Pools have to build up trust in order to get enough hash power to be viable, but some guy who pushes "buy hash power now" has no trust at all.
I sure hope like hell a significant majority of the bitcoin hash power isn't stupid enough to fall for this... otherwise bitcoin is done.
Maybe this is the establishment's way of bringing down BTC. Oh noes ...  |

I was referring to the 'proprietary implementation of ASIC and FPGA technology' that BFL is currently wowing us with...except there is no ASIC.
<troll> USB UARTs are ASICs right? </troll> Yeah. I am pretty sure they will be responsible for doubling the performance in the rig box. It's all in the USB hub, holmes. It is issues like this that still make me think there is something extremely dodgy about this BFL folks. Kind of hard to think they can scam $25k at once though so maybe there is an explanation. |

It would be interesting to see how well the 7970 can mine but IMHO until some months after release we will never really know. We need optimized kernels and OC.
One person can't bring all that I think. Maybe make a common fund and buy a card so that each dev gets some time with it etc. ?

Nice concept ! Great job spotting a gap in the leasing marketplace. Hope I get invited for being first to post  ! |

Don't tell me: another 1.05GHash/s, 20W, $499 preorder miracle box? Seems we're coming full circle.
No stated ghash, no stated wattage, no stated price, no pre-order (that I know of, yet). However, also no website or announcement either. Just wait a few months, keep your money to yourself, and watch the magic unfold. Lots of things are possible when you have plenty of money. So it is indeed them that have been unloading the BTC on Gox to fund this crap ASIC ? No wonder. |

I didn't think 6970s could hit 395 MH/s out of the box, unless they (Tomshardware) did some tweaking to theirs just to make it benchmark slightly above a 5870. Total BS in that article. Most of my 5870s can EASILY get a maximum of 440 Mhash/s when slightly overclocked to 960 MHz. 6XXX sucks compared to 5XXX. Even a 6990 sucks compared to the 5970 king ATM. A 6970 can almost never beat a 5870. Nobody really knows how the 7XXX will perform or behave until some months after release to allow for optimizations and OCing. |

Who do you think would have done this?
 That was my idea at first, too. It is a bit far fetched that someone intentionally burned down your house. Most likely the rig did all that since you have a lot of flammable material in there like books etc. |

I can make Gabicoin if you wish
Last thing we need is more CrapCoins right now. Focus on the existing wretches. |

Great work mate !!! So this should be pretty ideal for 5870 cards right ? What is the best setup for owners of 5870s right now in terms of SDK version, kernel, miner etc. ( software ) ? Thanks ! |

Just a rumor that will probably never become true. |

You guys didn't give BFL a chance. From day one on the original thread you were accusing them of being scammers.
Because we didn't believe their claims. And we were right. There is no 1GH/s, 20w, $700, miner. From BFL that is. Maybe someone already is using the 28nm tech and getting those figures. We can never be sure. |
|
|

Let us pray they don't literally ship a brick ... or at least something that will turn into a brick in 4 months etc. Some scammers get away with shipping a brick and claiming to have proof of delivery too and the buyer loses out. |

I highly doubt we will see any FPGA board based on 28 nm FPGA in the near and midterm.
Currently the Spartan 6 is becoming widely avaidable for low volume customers.
Spartan6 has been available in qty 100+ for over 1 year now. 28nm FPGAs are already sampling and will reach production in 1H2012. Spartan6 today is around 2X the MH/W of BFL, and the 28nm FPGAs should be 3X+. I know it can be argued both ways but, in the long run, MH/W determines how much profit a large miner will make, much more so than MH/$. The only way to remain profitable is
to have a MH/W that is significantly higher than the network average, and the only way to
do that is to adopt the most power-efficient technology as early as possible
(hosted in an area with the lowest possible electricity costs).-rph Exactly. +1 The 20W -> 80W fiasco is a big dent on BFL credibility. I can understand when you go maybe 1.5 times wrong but 4 times wrong is just laughable for respected engineers with 10 years of industry experience like BFL claim to have. Maybe they simulated that power draw too and that 19.8W is what the simulator showed ? |
