bigmykeI can replicate a warning in my event viewer on windows 7. It gave me 15,000+ errors in the last 24 hours. I have 680s in SLI and both are running in 16x with a sound card on the bottom slot running at PCIE 2.0. I get this error if I have pcie 3.0 enabled in the bios. If I enable the video cards to pcie 2.0 in the bios I can get the error to go away. I'm also experiencing stuttering during gameplay in a simple game such as Counter strike global offensive. I've never experienced such stuttering with my x79 setup. A corrected hardware error has occurred.Component: PCI Express Root PortError Source: Advanced Error Reporting (PCI Express)Bus:Device:Function: 0x0:0x3:0x0Vendor ID:Device ID: 0x8086:0x2f08Class Code: 0x30400The details view of this entry contains further information.
