Thread: PCI SERR with AMD but not NVIDIA
Post: RE: PCI SERR with AMD but not NVIDIA
| Sounds power-related to me. How big are the power supplies in these systems, and how many GPUs per system?
Most of the boards produced by Supermicro and Tyan have a clause buried deep in the docume... |

Thread: PCI SERR with AMD but not NVIDIA
Post: RE: PCI SERR with AMD but not NVIDIA
| That's a sufficiently large PSU, but I'm still kind of leaning towards power. Here's why:
With two cards that violate the PCI-e spec, you receive errors. With a card that adheres to the PCI-e spec,... |

Thread: PCI SERR with AMD but not NVIDIA
Post: RE: PCI SERR with AMD but not NVIDIA
| Just looks like an ASIC hang. +225 clock offset is rather aggressive (depending on the factory clocking), try reducing it to 200. |

Thread: PCI SERR with AMD but not NVIDIA
Post: RE: PCI SERR with AMD but not NVIDIA
| Ah yeah, +225 would put you at well over 1500 Mhz. Should be just fine at +100, and you could probably go up to +200 without issue. But for testing purposes +100 is a good number. |

Thread: PCI SERR with AMD but not NVIDIA
Post: RE: PCI SERR with AMD but not NVIDIA
| The 6990 draws like 125-150W more than the 290X, so yeah.
Yes, we have had several such cases, which is a big reason why we've moved away from AMD and are no longer going to sell any GPU that has a... |

Post: RE: PCI SERR with AMD but not NVIDIA
| The PCI-e slots get burned up from continually pulling more power than they can handle. Slots start dropping off one-by-one. |

Post: RE: PCI SERR with AMD but not NVIDIA
| Then I'm afraid you do not know your history. I have a stack of burned motherboards and power supplies that were once running HD 6990s that says your doubts are seriously misplaced.
