Question regarding PCIe speeds Tags: Asus Intel PCI Express Motherboards Product Last response: December 19, 2011 11:47 PM in Motherboards Share gjarnos December 19, 2011 10:10:24 PM ASUS Maximus IV Extreme-Z LGA 1155 Intel Z68 SATA 6Gb/s USB 3.0 Extended ATX Intel Motherboard Obviously a popular motherboard. I'm having trouble trying to figure out how each of these PCI ports operate. http://www.newegg.com/Product/Product.aspx?Item=N82E168... It says under the PCI specification: PCI Express 2.0 x16: 4 (x16 or dual x8 or x8, x16, x16) PCI Express x4: 1 PCI Express x1: 1 I am confused as to what this exactly means. Do the 2.0 ports operate at dual x16 speeds for SLI? I want to use two nVidia cards for SLI and I want to make sure I am getting dual x16.
