What uses PCIe lanes on motherboard?
Other devices that use PCIe lanes are expansion cards such as sound cards, networking cards, USB expansion cards, and raid controllers. If a CPU that only has 16 PCIe lanes is configured with a graphics card and an M.
How are PCIe lanes allocated?
Since PCIe lanes are scalable, more lanes connected to a device will multiply the data transfer speed. Therefore if an x1 device works at 1 bit per cycle, an x4 device will work at 4 bits per cycle but will also occupy 4 PCIe lanes. A typical graphics card is an x16 device and hence occupies 16 PCIe lanes.
Is it better to have more PCIe lanes?
Yes, choosing the PCIe slot closest to the processor (usually the topmost x16 slot) is recommended as it guarantees a full 16 PCIe lanes are wired to the slot, providing your graphics card with the best bandwidth and lowest latency.
How many PCIe lanes does SATA use?
Each of the X99’s SATA Express ports requires two PCI Express 2.0 lanes provided by the chipset, while the M. 2 slots can use either two 2.0 lanes from the chipset itself, or up to four 3.0 lanes taken directly from the LGA 2011-v3 CPU.

What are PCIe lanes?
What are PCIe lanes? A PCIe lane is a set of four wires or signal traces on a motherboard. Each lane uses two wires to send and two wires to receive data allowing for the full bandwidth to be utilised in both directions simultaneously. Each CPU can only support a limited number of PCIe lanes.
