Generally speaking yes. Given a PCIe 3.0 x16 slot, your PCIe 1.x and 2.x cards will be compatible. And yes, a x16 slot will support x16, x8, x4, x2, x1 cards. Have a look at this: https://www.pcisig.com/news_room/faqs/pcie3.0_faq/#EQ6


The answer is #1. The reason that there are two slots is to accommodate large expansion cards that may take up more then one slot. Typically this is video cards. They used to just leave an empty space beneath the pci express x16 slot, but then they started releasing cards that took up three slots. And then everything got complicated with SLI and ...


A good explanation can be found on the Wiki page itself here: A key difference between PCIe and earlier buses is a topology based on point-to-point serial links, rather than a shared parallel bus architecture. As well as here: Conceptually, the PCIe bus can be thought of as a high-speed serial replacement of the older (parallel) PCI/PCI-X ...


A PCIe 'lane' consists of 2 differential pairs of signals. One differential pair is used for sending and the other is used for receiving, which allows simultaneous bi-directional communication. Each lane is point-to-point. That is, each lane directly attaches a single host to a single device. PCIe switches can, however, be used when a host lane needs to be ...


You’re confusing “PCI” and “PCI Express”. They are not compatible. Your board does not have a PCI slot at all. So you cannot use this NIC.


I think you don't understand what 1 PCIe lane is. Many devices use more than 1 lane. For example - gaming graphics cards use 16 lanes. Some powerful gaming computers have two graphics cards - thats 32 PCIe lanes (two x16 ports). Intel i7-5820K can't handle two x16 graphics cards. For some gaming enthusiats or some engineers that may be a serious problem. ...


You can use "PC Wizard 2012" tool available in Hiren Boot CD. The PCIe version is shown in the Motheboard information.
