FAQ:

Q: What do the junction boxes on a PCI Express card represent?

A: white “junction boxes” represent PCI Express device downstream ports, while the gray ones represent upstream ports. PCI Express ×1 card containing a PCI Express switch (covered by a small heat sink), which creates multiple endpoints out of one endpoint and lets multiple devices share it

Q: What is the difference between a ×16 and ×4 PCI Express slot?

A: Its specification may read as “×16 (×4 mode)”, while “×size @ ×speed” notation (“×16 @ ×4”) is also common. The advantage is that such slots can accommodate a larger range of PCI Express cards without requiring motherboard hardware to support the full transfer rate. Standard mechanical sizes are ×1, ×4, ×8, and ×16.

Q: How much bandwidth can a 32-lane PCIe connector support?

A: Consequently, a 32-lane PCIe connector (×32) can support an aggregate throughput of up to 16 GB/s. PCIe 2.0 motherboard slots are fully backward compatible with PCIe v1.x cards. PCIe 2.0 cards are also generally backward compatible with PCIe 1.x motherboards, using the available bandwidth of PCI Express 1.1.

Q: Can a single-lane PCI Express card be used with multiple lanes?

A: For example, a single-lane PCI Express (×1) card can be inserted into a multi-lane slot (×4, ×8, etc.), and the initialization cycle auto-negotiates the highest mutually supported lane count. The link can dynamically down-configure itself to use fewer lanes, providing a failure tolerance in case bad or unreliable lanes are present.
