2x 5850 and a BFL Single = 1.6Gh/s The original plan was to have the two 5850s stacked on top of each other using 50mm motherboard spacers, like the icarus boards were done, but it turns out two of the PCIe slots (one is actually UIO or something) on the motherboard are meant to be used with a proprietary riser, which I don't have. The BIOS/OS freaks out about IRQ assignment if I plug a card in either of them. So... I had to put one GPU on the other side :/ The server is used for game hosting and general messing with, I figured why not bitcoin mine on it too  I took a CPU and its RAM out while trying to figure out the PCIe slot problems, but I'll probably put them back in a few days... 2x 1.8Ghz 6-core shanghai Opterons 16GB RAM https://i.imgur.com/X1uwy.jpg?1?2848 |

here are 2 pics taken from one of my rigs..
5x5850's in the left motherboard and 3x5850 in the right. 2x segotep GP1100G power supplies, each powering 4 cards:
What speeds are you getting out of that? 2.8 GH? around 340Mhash / card, oc'ing them to 825/200. running stable with uptimes 10-30 days on my other places. this one was rebooted today after an 8 days uptime. |

CUT THE ZIPTIES! Haha, that's an inside joke on my robotics team that nobody here will get.  The inside joke that goes on between my friends is "Green is bilge." So, I don't ever use green wire when I personally do anything unless it's what we would call as "always-on." |

 Simple GPU miner with 1x 5850 and 1x 7970. Pulls 370 watts at the wall with some tweaking of the GPUs. 59C for the 7970 and 68C for the 5850. 850 Mhash/s P.S. Picture was taken by Potato 2000 |

If you're not excited by the idea of being an early adopter 'now', then you should come back in three or four years and either tell us "Told you it'd never work!" or join what should, by then, be a much more stable and easier-to-use system.

One 7970 can do ~700, one 5850 can ~320 easy I don't like to mess with overclocks, it would get quite hot in the garage, instability issues, temperature issues, and high power consumption. The higher hash rate vs power consumption isn't worth it. In the end you'll have accelerated electromigration and dead cards. |

You can increase GPU speed and reduce Voltage in same line. When you go to set a Formula1 Race team, you can not start with a Golf R36 and hope to win.  |

The problem is racing cars have constantly burnt out tires, while graphics cards have electromigration and total errosion of GPU long term |

Here's my Lego mining rig  2x5850 still under construction (a third 5850 is on the way).

Or smuggle a new toy into the kids' room because all other rooms are already full with overheating rigs. Not sure if the EMR is healthy though. |

For a proper analogy, I'd equate worn tires to a burnt out fan, and electromigration to a blown engine. Great analogy But if any "parts" in the actual engine break then you're doomed. Anyways it's much better for me because I wouldn't gain much and it helps keep the temperatures low and my power consumption down. |
