Yellow (that 'third wire') is sense. You can use the ASUS fan safely as long as you don't botch the cablology. That cooler is not necessarily crap, be advised that heatpipe orientation can make one hell of a difference. I actually have two 5870 with same/similar cooler and it only cools the GPU well with fan @ 85% (only ~3.2k RPM, they aren't fast), VRAM modules and VRMs get pretty hot. but thanks for the link, I did notice a difference of several degrees with different orientation, even though the card now gets a bit of warm PSU exhaust air and gets probably slightly warmer inhaust air because there are cables close to the fans. In a seemingly better position (-90deg) the temperatures were worse (5-6C). |

I'm wondering if someone can help me connect to Slush's pool through Tor. I have the Tor client set up and running, and am able to download the blockchain in the client by setting the client to use a sock4 proxy. However, I'm having no luck with setting up GUIMiner to connect. I get a "Problems communicating with bitcoin RPC" error when trying to connect to host pool57wkuu5yuhzb.onion on port 8332. Are those the correct settings, and do I have to edit some kind of config file to set guiminer to use a socks proxy?
No idea but are you using poclbm or other miner? BTW. Why did slush go down just now? EDIT: ok, it is up running again. |

So who do you think has been more open and honest so far? |

The thing is, they probably don't have 300 units available, more like, 300 in queue to be set up from parts, tested and shipped to customers whose money were necessary to produce/buy them. 6 month warranty suggests they themselves don't believe in their product lasting too long. Waiting for (mini?) rig box and competition. |

I assumed that people on this forum--who use a decentralized currency--would appreciate a book on privacy.
I was wrong.
I might be wrong, but I think a lot of people here already know this stuff. Maybe you could try selling it on Amazon? If I could get my hands on a paper edition of your book and spend 30-60 seconds on skimming through it I would know if it is worth (for me at least, I'm not sure how much if any of the information provided in your book is new to me) those $25. I'll be watching this thread and see if any reputable forum members posts reviews of it. What I would do if I were you would be to give it for free or with a discount to one of the mods or admins on this forum and ask them for thorough review in return. |

I have tried a couple models on HD5770's, HD5830 Extremes and HD6950's.
What max. temperature did you get on each cooler and fan on each of those GPUs? What's your ambient temp. and which paste did you use? |

If you do decide to invest money into making use of you PCI slot definitely use a powered extender. Doesn't matter if it's x1-x1, x16-x1, x1-x16 or some other, power comes only from x1 pins: http://en.wikipedia.org/wiki/PCI_Express#PinoutWhy powered extender? AFAIK PCI slot can give max. 25W PCI-E - 75W Doesn't mean it won't work, only it is safer to use a powered extender. |

Maybe try with another network controller (PCI ethernet card)? |

You are still trying to sell it.. at that price xD

its lubuntu 11.04
thanks, is it 32 or 64 bit? |

first time I've ever heard of monitor on/off effecting hash rate. try swapping GPUs around so a different one is gpu 0, maybe will go away.
Just had time to check bamt with fat16, boots and works flawlessly now, will toss you a coin first thing in the morning  EDIT: Tossed. |

Run the numbers again. Sure it is fairly bad pricewise, but it has the potential of being actually quite efficient, both on electricity and more importantly on space. Instead of having a CPU/RAM/mobo for every 8GPUs, I have 2 CPUs (could be 1 if I wanted), some RAM, and a mobo for up to 36 GPUs (including dual-GPU cards).
I assume CPU cycles will start to become significant with that many GPU's and miner threads. Will a single core CPU be enough to run all of that without becoming a bottleneck? I would say that it wouldn't become a bottleneck. the BFL singles can be stacked up to 100 units on 1 machine. That'd be more than 80GH/s with 1 CPU. Rjk will have to choose a set of OS, drivers and SDK without the 100% CPU bug, otherwise it is possible that the GPUs will not be utilized in 100% (that's what I have with 12.1 and 2.6, where I have to make the miner use all 4 cpu cores (got 5 gpus), if it's 1-3 then the GPUs will work at 70-95% of their proper speed. |

I had a monitor hooked up to a rig for some time because I was testing lowest energy consuming BIOS settings (no way to do that remotely I think at least not cheaply). Didn't get any problems after turning it off but I did once I unplugged it (bamt crashed, but it was more driver-related as far as I remember), I remember another user here having the same problem but the solution is to unplug the monitor after saving the BIOS settings (before booting bamt). But this is really not much of a problem  Once you have everything set up, boot the rig without the monitor and see throught web gpumon or ssh if everything's correct. It happens for you with all gpus, regardless of the slot used? |

Is this a hoax? Can someone post a pic of the actual article?

The singles have a 6 month warranty, which is longer than any other similar product with the exception of Ztex's 2 year warranty.
GPUs have 2 years to lifetime warranties. |

Some error, I doubt they will actually ship it for this much.

Sorry but I don't speak russian; which Linux did you use? 11.6 and 2.4 looks like bamt to me..
|
|
|
|
Which drivers and SDK versions did you use? EDIT: just saw that russian thread, 11.6 and 2.4, anyone can tell what was the OS (linux thats all I know, is it bamt perchance?) |

Hello Everyone,
We wanted to evaluate the market and ask our fellow customers whether a Mini-Rig operating
at 25 GH/s and priced at half price (15K$) and consuming around 1.2KW would be something they
consider or not.
All suggestions/ideas/opinions are welcome.
Reagrds,
BFL
If this is the price after taxes/duties/shipping to EU countries (or you manage to ship from EU) I'll be interested. EDIT: You HAVE to provide decent warranty. That means at least 24 months, this is the min. what GPU manufacturers provide. Note that GPUs are possible to resell if bitcoin crashes again or to use for other tasks apart from mining. You need to design something that is below 1500w current draw, so it can be used on a normal household circuit. With the 5x more power usage per hash than your original specification, "rigbox" can't be plugged into anything beyond a specialized circuit with a high-amperage nema plug.
Sure it can, depends on where you live. We have 16A 230V household citcuits here. |

Shouldn't you adher to full disclosure policy? This would actually encourage people to update.
If you look a discussion about full disclosure you'll see that much of the discussion is completely moot when the "vendors" of the software are also the discoverers of the issue. There also isn't much more that could be disclosed right now.  |
