My 5970s are all running stable at 920mV and 680Mhz.
Of course, YMMV.

This is a thread to discuss the hardware and performance of the Bitforce Single and Bitforce Rig Box
So far, I get 0 hashes per second from the Bitforce Single and 0 hashes per second from the Bitforce Rig Box. On the other hand, they also used 0 watts of electricity to produce 0 hashes. The hardware is very photogenic. At least, it appears to be so in pictures seen so far. |

Unless the idle draw of the cards represents the same amount of logical work done, you can't just subtract them out to get the "mining" power consumed.
If one card idles hot doing tons of work that is not mining related, subtracting that from the final mining number misrepresents how much power that card actually draws in order to mine. Especially if it stops doing that work while mining. Conversely, if one card idles cold it won't have any idle wattage to subtract making its mining numbers seem like they draw more power.
The only numbers that can be compared are 100% mining vs 100% mining. Unless someone wants to map out exactly how much logical work each card does while idle and pro-rate their wattage for the extra work done...
Idle card does no work. i.e. 0 mhash/s. Look at it this way. System at load: 300W System at idle (including GPU idle wattage): 100W GPU idle wattage: 10W The reason we wan't to subtract the GPU idle wattage is to get the true GPU load wattage. 100W - 10W = 90W (system idle w/o no GPU). 300W - 90W = 210W (GPU full wattage at load). Now we have apples to apples comparison, the GPU wattage at load. We can also predict other system values. system w/ 1 GPU = 90W + 1*210W = 300W system w/ 2 GPUs = 90W + 2*210W = 510W system w/ 3 GPUs = 90W + 3*210W = 720W system w/ 4 GPUs = 90W + 4*210W = 930W system w/ 5 GPUs = 90W + 5*210W = 1140W system w/ 6 GPUs = 90W + 6*210W = 1350W Idle cards do no hashing related work. But it consumes watts. Therefore it does work. Explain exactly all of the instructions executed (like monitoring and answering driver polls, DMA channel, etc). If this work is accomplished only on an idle card and not on a mining card, then we need to account for that. Once those are accounted for we can compare to see if one card is providing say "full service with frills" to the OS, and the other card is "self service" while idle. That condition can skew the measurements. Especially with a card designed to go very cold while idle vs one that runs hot with idle cycles. Apples to oranges. Edit: A concrete example follows. The AMD Phenom II X6 1100T (3.3GHz) consumes 20w while idle, and 109w under full load. The Intel Core i7 2600K @ 4.4GHz consumes 5w while idle, and 111w under full load. While under full load (in theory), the CPUs are not executing any idle cycles. Also, voltage may be stepped down while idle and parts of the chip shut off further skewing the comparison. Subtracting those 20 from 109 & 5 from 111 will not give you anything useful. |

At least label your wattage numbers so we know if they are total or not  And if they are not total, write the total watts in there too. |

I would not count much on the accuracy of the voltage and current sensors, it would be better to calculate a rig with onbard graphics and then this same rig with a 7970 @ 100% load. That's assuming the CPU had same load in both cases. Did you even read what I said? It's within 5% of my calculated figures, so it is more than likely more accurate than what I calculated. Or they are inferring it from other sources instead of measuring it directly. Totals watts from wall / total hashes from rig = gold standard. Sure, but I measured all possible sources now. :p You should buy beg borrow or steal a 5970 and do a head to head with the same rig. 100% vs 100% mining flat out under various voltages & core speeds, with MH/s and watts in a pretty spreadsheet. Mmmmm...spreadsheets.  |

Now solidcoin.info is down
So is solidcointalk.org. Another DMCA takedown? I doubt it. Usually DMCA takedowns results in a DMCA takedown notice. Maybe he just forgot to pay his monthly bill. |

You got chicken entrails to work with tea leaves on an Ouija board? I get a BSOD every time I try that.
You must be running Windows.  I have to run Windows, there is no Linux driver for tea leaves.  |

Is there a point to this calculation other than the academic exercise? Using the terms 'bitcoin' and 'per year' in the same context is meaningless. We all know what has/can/will happen to $/BTC and network difficulty in the span of a year.
Forecasting forward even a month is challenging enough even with the benefit of a crystal ball, tea leaves, chicken entrails, and a Ouija board. Let's not forget the halving of the block reward come December ... but that is a separate issue.
If one had that much money to risk, it may make more sense to buy BTC directly and trade it opportunistically throughout the year.

If those numbers are correct, these cards are double in term of efficiency.
Not really, more like ~0% stock and ~ +30% undervolted at stock clock vs. my old 5970 numbers here. Guess we'll never know why on earth AMD decided to go with 1.175V core at 925 MHz, so far all cards seem perfectly happy at 0.95-1.05V at 925 core for mining and 3D. While at stock V they seem to OC to 1050-1120 MHz...  Now the big Q: if those aren't cherry-picked chips, what will 7990s be able to reach? A little bird told me AMD is kicking themselves for clocking them too low. |

After being idle for 7 days in #solidcoin (the last time I spoke was before the DMCA takedown) I noticed this little gem: * ChanServ gives channel operator status to RealSolid * RealSolid sets ban on *!*@..snip * You have been kicked from #solidcoin by RealSolid (k9quaint) I guess I will have to read logs of the channel instead. |

I don't think BCX actually started the hammering here... wasn't it in fact RS/CH/Douchebag who started whining that he had been banned? Wasn't this conversation more of a reflection on the absurdity of that little simpleton complaining about this forum?
Actually, I think BCX has demonstrated quite capably that she has a life, and if she chooses to use a very minor fraction of that life keeping a public awareness of the infantile, dishonest and simply pathetic foolishness that spews forth from the land of the ShortBusCoin, maybe she is just doing us all a favor.
While RS/CH/Douchebag just continues being a sociopath attacking for no reason other than his own self gratification. He really should be banned from any discourse between intelligent people, he brings down the tone, the intelligence and the quality of any venue he enters.

Americas or Europe's copyright laws do not apply where I live.
It would be funny to see asshat go to court and have 90% of the bitcoin world go offline while this is sorted.
Would this not be an effective attack on bitcoin. Someone just say they own the code and have SOPA take down everything? Sure it will come back but just think of the damage. I would guess we should all be working on trying to get as much of this p2p as we can.
Those laws may not apply, but all I have to do is claim you defamed the Thai monarchy. Then you and your website go *poof*. (I might have to bribe one or two judges) Thailand does not really work in the same way as the west. There would first be an investigation (yeah crazy!) and if the claim is false you would end up in jail. One of the advantages of being in a kingdom. You didn't read the part where I paid the bribe. Hope you are poor so the magistrate doesn't come back wanting more cash to squirrel you away. |

Fuck I hate solid coin (shit coin) but I think I might just support him in court... This little boy goes and calls 911 when he thinks his money/time will be lost and then claims he is doing the work of Jesus. Ignorance is bliss I guess. LOL
You should probably learn a little bit about copyright law before you spout off about it. By asserting ownership of code in bitcoin, Coinhunter now has the ability to sue anyone who uses that code in their projects. Unless that ownership claim is contested he can claim copyright infringement by every person using the Bitcoin client. Coinhunter could have pointed to his license.txt and claimed that Bitcoin infringed on it and issued a DMCA takedown of the bitcoin github site. He can send the same notices to ISPs who host the major bitcoin pools and claim they are running infringing code. Ultimately, Coinhunter would lose in court (since he does not in fact own the copyrights) and the bitcoin pools would be put back on the internet and the bitcoin github site would be restored. However, while it was decided in the courts, large sections of bitcoin could be offline. It could take weeks or even months to decide the issue, which is why nobody wants to take that risk. The current state of copyright law is such that "infringers" are guilty until proven innocent. This is why you should invade Washington D.C. and Brussels. |
