Yeah if it were me to go back and rethink my farm I'd just go with higher hash cards on less per rig though. Nothing sucks quite like a ton of noisy 5770's compared to a couple of 5870's.
Noise isn't an issue for me. I run reference 5870 and 5970 fans at 100%. It's all in the basement sucking electricity from a dryer socket where I can -barely- hear it and I'm directly above the rigs. |

I apologize to op,\was drinking last night and didn't mention I use a pci to pci-e adapter on my 2 790FX-GD70's. Last time I browse the interwebs on hard liquor. lol
Yeah I have one of those. They're expensive though about about $20 per PCI-E slot added. |

Personally I think they've taken notice from 6xxx series and made gpu computing power one of the main priorities. Just look at the jump from the 6970 to the 7970 in terms of hash rate. Following on the rise I predict 800mhash from the 8970 maybe 8950
The increase in hashrate was because of the new GCN architecture of the 7xxx cards. IIRC, the 8xxx cards will also be using the same GCN. I actually don't expect to see any massive improvements in BTC mining (think 5xxx -> 6xxx improvements). IMO, I blame the increase from 1536 shaders to 2048 shaders |

I am sorry if this is not the right thread, I am just getting frustrated searching the internet and coming up empty. Certainly someone here has had the same problem, since this is a cheap PSU for 850 Watts. DOes anyone know where I can buy extra PCI-E 6 and 8 pin cables for this model PSU? (TR2 RX 850W) I cant find anything anywhere relating to extra cables and the thermaltake website does not seem to support more cables for this particular model, although they only include enough for 2 GPU's. Any suggestions would be helpful.
Thanks All!!
If you dont get them, you can always go for sata->pcie power adapter. Usually people have spare sata power I'd be careful with molex/sata to PCI-E. You're supplying 12v power and ground over only 1 wire each. PCI-E uses 3 wires each, plus 2 extra grounds for the bigger 8 pin. I would be very careful and not apply a load greater than 75 watts per 12v wire, or you risk burning out the terminals/melting the wire like I did. |

would be nice to get in on this, but I consistently sell my BTC for 6-10% above market value, so selling them to you for about 5% above market is still a loss on my end. I could do something something else though as long as it isn't bitcoin.
How do you consistently sell your BTC for 6-10% above market value? personal deals? otc. Should be enough details there for you to figure out. check my sig |

Z77A-GD80 + Intel i3-3225 + stock HSF + 2GB Samsung low-profile DDR3 1333
$270 shipped
Out of my price range, sorry. Keep the offers coming though. MrB was selling combos for $100 a while back, so I'm hoping to get a similar price.  |

work on that focus. too much blurry
Any photos in particular you'd like to see? Take a well focused pic of OTHER SIDE if the "Unknown processor - 0.25BTC" Added a photo of the other side sure is a lot of thermal paste gunk on that. Looks like an LGA775. If you take some rubbing alcohol or goo gone to some paper towel and rub the thermal gunk off, it'll show a bunch of info including the processor model. just trying to help |

Got the tracking number. Feb 9 and still nothing, tracking info says its still stuck in Idaho...
What a bizarre deal. I am calling the USPS on Monday. Thank you. I also ordered a rosewill from newegg because I am in dire need of one. |

A few 790 boards accept 6 gpu's with extensions. I have 2 myself.
Mind saying? |

Hi
I have a Butterfly Labs Single that I want to sell.
Hashing great at 832Mh/s firmware.
I am looking for 50 BTC.
PM me if interested.
You want over $1200 for a BFL single? LOLOOLOLOLOLOL |

Looking to buy a combo that can fit 6 graphics cards, with or without PCI-E riser cables, either intel or AMD, and preferably either gigabyte or MSI but might take others. Preferably very low end, power efficient CPU's. Only need 2GB RAM at the minimum. Heatsink + fan is mandatory. List of motherboards that accept 6 cards from what I can tell.
AMD Gigabyte boards.
GA-990FXA-UD7, GA-990FXA-UD5, GA-990FXA-UD3, GA-890FXA-UD7, GA-890FXA-UD5
AMD MSI boards.
990FXA-GD80V2, 990FXA-GD80, 990FXA-GD65V2, 990FXA-GD65, 990XA-GD55, 890FXA-GD70, 890FXA-GD65
Intel Gigabyte boards.
G1.Sniper 3, GA-Z77X-UD5H, GA-Z77X-UP5, GA-Z77X-UD4H, GA-Z77X-UP4, GA-Z77X-UD3H, GA-Z77X-D3H
Intel MSI boards.
Z77 MPOWER, Z77A-GD80, Z77A-GD65, Z77A-GD55, Z77A-G45
I personally have 2 MSI Z77A-g45 boards that are verified to run 6 cards (Has 7 PCI-E slots. One 1x slot shuts off though when the adjacent one is populated.)
Looking for $100 shipped to 54501, USA. Payment type negotiable.

If someone can find one of these too, I need one as well. I have ziptied 2 80mm fans to my gigabyte 5850, and I can't resell it for a decent amount of money unless it looks original.

Thanks for the offer... I keep spare fans around though.
Have you tried starting the 5970 at very low clocks (600-650ish) and waiting for it to heat up? I've got 3 cards that do this (they need reflowed). Once they are up to temperature though (60c+), they run flawlessly at higher clocks.
this is kidna whats happening to one of my 5970, but one of the cores wont accept any load at all (mining) unless the adjacent core heats it up to about 65-70C, then I can start it at normal clock speeds. It's a crappy card anyways though. Master maxes out at 740Mhz @ 1v, slave maxes at 755 @ 1v. Most of my other 5970 get about 770-800ish. |

Re-organized my miners for making room for more GPU rigs (yup, still GPU mining) as well as proper electrical sockets. Click pictures for bigger version. Electrical box before.. No faceplate, 16awg wiring, plugs into a 3 prong dryer socket. 250 volts and 30 amps.  Electrical box after. Faceplates, duplex sockets, internally wired with 10awg wiring. Much thicker and safer.  And the miners themselves. Before (Was posted in this thread once already)  And after with metal racks. Easier to remove graphics cards, lower profile.  |

Nah the pool URL didn't fix it. Must just be incompatible with CGMiner....Oh well, thanks for the efforts bud.
I assure you cgminer is compatible with slush. Do you really have 4 GPU's in your system? |

I'm not sure why BFGminer would be maxxing out your CPU (its a GPU miner).
Also CPU mining is disabled in the binary. You have to enable it yourself in the source and compile it yourself to CPU mine with bfgminer. |
