Will you take 55BTC? Escrow?
I'll have to leave it open at that price as there are a few others interested - give them a chance to respond. I have no problems with the concept of escrow however in this case I need to transact quick and there is no physical handover. And in effect HorseRider is acting as escrow agent anyway. |

No need to post a sum or something - just a simple x(@)y will do to avoid confusing the poor bot.  Would you open source the bot? Seems like interesting code.  John makes enough off this community so that 'bot' is probably code for internsittinginthecupboardinthedark.  |

I never asked for the pci-e 2.0 spec. I stated a fact and it remains fact that the pci-e 2.0 slot is capable of delivering 150 watts. Your ignorance must be bliss.
Pci-e 2.0 is capable of delivering 150w not 75.
What you've suggested is the standard is capable of delivering 150W. So if I took any PCI-E 2.0 motherboard off the shelf, I could power a 150W graphics card from it. You can't, the standard isn't and you're wrong. You can't say the slot can supply 150W if it can't. Why do you think the Malta 7990 is 375W? 2x150W PCI-E 8 pin connectors = 300W. 375W - 300W does not equal 150W. Here we go again, you're forgetting TDP is not max capable power draw. The specified TDP is only what the stock heatsink is required to dissipate. What do you think happens when you overvolt and overclock? Same goes for cpus. An i5-3570k has a tdp of 77 watts but overclock it and power consumption can easily double that number. No shit its not, but those 2 numbers happen to line up in this particular case. |

You can cool the oil...
Does anybody know the measurements of the heat sink? I will let myself manufacture some water cooling elements, maybe I also offer them for sale.
You can cool the oil via a heat exchanger, but then what is the point of using the oil to substitute air if you then have to use a heat exchanger to cool it and a dissipation system to move it? |

I would suggest that as a US company, BFL is 'more' bound to be FCC approved. Avalon would only be being naughty when it sold units into FCC zone countries, where as say its domestic China units can probably do what they want.

By that logic there is no "work", only "heat". And that's simply not true. The useful work performed here is in moving heat from one place to another through convection. This is not complicated.
Next we'll be arguing that there's no useful work in the entire universe, only heat....
In the use of a fan, electrical energy is converted to work which is very quickly and consistently turned to heat. Why do you think a fan makes a room hotter? Because it is converted electricity to heat. -anyway, this is fans. In electronics there is zero work as the cycle happens so fast. Apart from the tiny portion of energy required to 'start' the cycle, all the conversion is from electricity to heat. Again, in case I was not clear. By your logic the Saturn V "did no work". But there is a more profound error you make, which is in asserting that a fan, in moving heat from one place to another, "does no work". That's wrong, of course it does work. In fact, that's the very definition of work in a thermodynamic sense. I replied to this conversation because it seemed interesting, but if you continue to stand on ignorance, this will get dull quickly. What I was trying to point out is there is a difference between temporary and permanent work. Compare lifting a weight on a ratchet and our fan. While lifting the weight, work is done and stored in PE. When you stop putting in work, it stays and there is a clear and stored outcome of the work. With the fan, as soon as we stop the fan, everything has returned to pre-fan conditions. The air is a fluid so regardless of how you move it, it will still settle to a [now hotter] equilibrium and your work was converted entirely to heat. In the case of your rocket, it clearly did permanent work as maybe 5% of the energy consumed is stored as PE above the earth. The rest was consumed as heat. Well, since you want to look at the rocket in that fashion, I also, will use your method. By way of the virial theorum, the additional heat I added to the atmosphere by way of my fan has caused the gas envelope of the planet to become hotter, and thus it has expanded - admittedly, quite slightly. We can show that of this expansion, 50% is a potential energy increase, and 50% is a kinetic energy increase. When you look at it in more detail it doesn't work that way. The air will give up its 'additional' heat by convection and interfluid diffusivity to EVERYTHING else, to the point the 'gas envelope' is unchanged. |

With regards to power throttling, there's a powertune +20% option. I believe that should let you mine without trouble, as it allows for 375W*1.2 = 450W. Furmark is indeed not a good benchmark, it is considered a 'power virus'. Even if power is a problem, slight undervolting should take care of that.
Temperatures and cooling may be a problem, but it's a matter of ambient temps and airflow. If you have an open air rig with extenders and plenty of space for the cards, I'm sure you'll be fine.
The question is more about whether it's a good idea to buy a $1000 card for mining now, instead of getting multiple 5xxx/79xx cards or an ASIC. Or just buying coins directly. The time of GPUs might be coming to an end.
The limit is the cooling system and power DELIVERY in this case [same as you'd have on a high end SINGLE 7970 with a little more beef]. It doesn't matter if you tell the card its allowed more than designed as in this case its hard limited by the power delivery system. 75W PCIE and 2x150W PCIE 8 pins = 375W. Can't 'force' more due to the onboard hardware without seriously seriously risking card death. ... Still not caught on that power consumption is equal or very near to heat output? Pci-e 2.0 is capable of delivering 150w not 75. About the power consumption yes you're right. I was thinking of something entirely different. Are you sitting there constantly refreshing the screen? I cannot fathom how you can reply so fast unless you have nothing better to do. blah blah blah Try looking for a more updated revision next time. Why in the world do you think some motherboards have molex connectors near the pci-e slots? The slot is capable of delivering 150w. There are even bios settings on some boards that allow you to change from 75w to 150w. It would be impossible to overclock some cards without having that extra power from the slot. You asked for the PCI-E 2.0 specification, I gave it you. If you want to argue they made the specification wrong then go argue with them - your insolence is incredible. |

My 7970s at 901 MHz core / 1512 MHz RAM / 937 mV core pull about 170w AC (140w DC) per card while getting 630 KH/s. This is without touching the power limiter. I seriously doubt Malta will have a problem mining litecoins. The 2x 8-pins themselves can give enough power to run the card at low clocks/volts, let alone the PCI-e slot. The reference 7970 I have, by the way, runs at <60C load next a bunch of 6950s that run at 85C load. Tahiti is insanely energy efficient when it comes to scrypt.
I believe there is a difference between being FORCED to mine on low clocks and having the option to mine at low clocks. This is after all a $1k card. |

I cannot fathom how you can reply so fast unless you have nothing better to do. Look at the time stamps, same goes for you. I have 42 tabs open while im writing technical reports and they auto refresh every 20 minutes. Obviously you call 'tryhard' when you finally realise you were wrong, rather than telling me I 'need some lessons' or 'get your facts right'. PCI-E 2.0 is capable of 75W, as I've said time and time again. This is from electrical specification document by PCI-SIG for PCI-E 2.0: http://www.doc88.com/p-90922403627.html.

Check in GPU-Z what you can see - rules out a pure software cause.
If its not showing much its at a driver level. Try a CLEAN install = uninstall, restart, restart, uninstall default, restart and install actual.

The Malta would certainly have trouble IF it used the exact same chips used in the Powercolor version. But the Malta uses higher binned chips that are more efficient which is why they can give the Malta a 375w TDP
Looking at the data, I don't believe they are. Stock clocks less than 1GHz chips, max overclocks seem similar to my PC boards and less than decent 7970s. Power consumption was 15W less than the PC, no where near enough to make up for the lack of power headroom. I'm not sure how you missed this in the Anand review you were touting so much about But perhaps the most defining aspect of AMD’s 7990, and the thing that sets it apart from unofficial 7990s that came before it is the TDP. AMD’s 7990 has an official TDP of just 375W, which although common for official dual-GPU cards, is quite a bit lower than the TDPs of the unofficial 7990s. As the GPU manufacturer AMD has the ability to do finely grained binning that their partners cannot, so while Asus and PowerColor have essentially been putting together cards that really are two 7970s on a single card – right down to the TDP – official 7990s get the advantage of AMD’s binning process, significantly reducing power consumption. Third paragraph below the spec comparison table http://www.anandtech.com/show/6915/amd-radeon-hd-7990-review-7990-gets-officialNo, its like me offering you a bet as to how many cups I have on my desk right now. Regardless of the true answer, I can easily fake it and there is no way to prove otherwise. I'd have to be well, you, to accept that bet.
I'm not sure how I could possibly fake pictures of the setup and cgminer running. I'm sure it can be done but it is certainly beyond my ability to do so. I've read that, looking at specs tells us nothing other than one heat system can remove 375W and one 525W - that's not an indication of actual performance. If you look at the actual power consumption in Anand's review you'll see the cards aren't more than 15W apart. The 'bet' is surrounding cooling and power solutions. How am I to know if you put it next to a 5C AC and go "oh look not overheating". No I don't and I don't trust you enough to even believe your name. Now you bring in ambient temps ha! You're full of excuses aren't you? I'll leave it at that. .... Yes? As already discussed ambient is going to affect power usage and actual TDP of the cooling? Really, this is why you're what, 35, and still running a piddly little computer store trying to sell usb cables to diddy old grannies. |

I think I'm intermediate with Linux, Ubuntu in particular, I've been using it for about 9 years, usually I'm very good finding solutions and following directions.
I'm trying to get xubuntu working. Here is an initial guide: https://docs.google.com/document/d/1Gw7YPYgMgNNU42skibULbJJUx_suP_CpjSEdSi8_z9U/edit?pli=1#I suggest you join ubuntuforums.com and read up. You'll also have to get that USB Wifi adapter working, and it might be a pain depending on the company/model. Thanks for the advice, I think I had that bookmarked somewhere. I think going Linux saves me about $200, because I don't have to buy a hard drive or a Windows copy. I do enjoy a challenge once in a while. Refurbished hard drives literally cost $15-20 off ebay, not sure about US pricing but in the UK they're dirt cheap. And windows can be err, you know.... |
