I was going to post new pictures today but there has been a problem. Motherboard failure! New board tomorrow. New thread tomorrow. No need for a new thread, just keep it in this one. Grant Darwin NT |

The mb was only 2 weeks old. Had problems from the start. I ordered a new mb last week cause i really, really hated this one! There was no OC on the mb or the 480 cards. Jon |

What you want to do? :-) 7x GTX480 on one mobo? What a monster machine this will be! If 2+ WUs/GPU, then maybe a 2x CPU (8 (or 12) threads each) mobo or a 12 threads CPU for single socket mobo would be well for well performance/support? You have maybe infos about the PCIe cable connectors/connection? To now I didn't found infos about. All 16 lanes of a PCIe x16 slot are connected and will be transferred? They have a speed limit? PCIe 2.0 is possible? |

What you want to do? :-) Slots: Seven PCI Express 2.0 x16 slots (first, third, fifth and seventh slots working at x16 when up to four video cards are installed, and speed reduced to x8 when five or more video cards are installed) That price in my link is Australian $. Average price in the US*: USD 595.00 Here is a link to more information about the board. |

AFAIK, at least PCIe 2.0 x8 (or PCIe 1.0 x16) speed is needed for well CUDA crunching. So if Jon's GIGABYTE mobo support this also he could let run 7 GTX480. WOW! EDIT: But maybe faster PCIe speed is needed if 2+ WUs/GPU? |

Good news and bad news. Th new mb came in installed. Everything was good until the fire. Not really a fire but smoke coming from the wires. The wires are from the Dual Power Supply Adapter Cable http://www.frozencpu.com/products/5637/cpa-167/Lian_Li_Dual_Power_Supply_Adapter_Cable.html. Small part of the Adapter and the 24pin plug melted. Pulled apart when it cooled but not sure if i want to use that psu. have a 1000W psu i can use in place of it. |

Here's hoping it's the PSU and not something to do with the new MB. PROUD MEMBER OF Team Starfire World BOINC |

Maybe too much wattage for the adapter? Some infos in the specs? |
Jon Send message Joined: 12 Aug 09 Posts: 157 Credit: 139,063,241 RAC: 0 |
I think it was the adapter. More damage to it that the 24pin plug. At the time there was the i7-980 and 3 cards. BTW i changed to i7-920 to a i7-980 from another computer. |

A 12 thread-CPU is a very nice thing.. :-) |

When I tried 2 power supplies I stripped a bit of the green and black wires going to the MB and ran a wire from green to green and black to black and they both started at the same time and ran fine...Had to use a second PS until my 1250 watt arrived.

AFAIK, at least PCIe 2.0 x8 (or PCIe 1.0 x16) speed is needed for well CUDA crunching. I crunch for S@H with a 16x and a 4x pci-e slot as I have a GTX295 in each, So I don't know where You got the 8x requirement, As 4x or possibly even 2x would do just fine. Savoir-Faire is everywhere!

That cable is only supposed to allow the 2nd psu to turn on or off with the 1st psu, That's why the Green wire(power Good) and a Black wire(Ground) are only included. Savoir-Faire is everywhere!

"only suppose to" is the key, kind of like painting on load direction arrows on aircraft structure so the load knows where to go, lol. so please explain why that was the wire that melted? |

What if you would just turn the psu into always on ? I remember reading about that when I planned to turn one of my old power supplies into a poor mans lab psu. It only takes a power resistor. Here is the link to the page. You might have to dig a little. http://www.wikihow.com/Convert-a-Computer-ATX-Power-Supply-to-a-Lab-Power-Supply |

"only suppose to" is the key, kind of like painting on load direction arrows on aircraft structure so the load knows where to go, lol. Well I'm not an electrician, Black carries no voltage as It's ground, It should only be carrying the signal for power good, Too small a wire gauge is My guess It's not the two small wires by themselves, It's the ones that carry the voltage, Like the Yellow(12v), Red(5v) and Orange(3.3v) wires. What I would like to know is which wire on which cable melted? The two wires, the Green and Black shouldn't do anything, If they did a metal paperclip would get warm and I've never seen that happen even once. http://mail.ultraproducts.com/product_details.php?cPath=12&pPath=584&productID=584 http://www.performance-pcs.com/catalog/index.php?main_page=product_info&products_id=21193 Frozencpu Savoir-Faire is everywhere!
