I’m trying to interpret the technical details on the Asus TUF Gaming B660m-Plus D4. The specs mention several PCIe slots and chipsets. The part about "supports x4 mode" suggests compatibility with faster data lanes—likely allowing it to operate in both 16 lanes (PCIe 3.0 x16) and 4 lanes (PCIe 4.0 x1). This means the motherboard can switch between higher bandwidth configurations depending on the needs of the system.
PCH stands for Peripheral Component Interconnect, a type of bus used in some Intel chipsets like Optane. It’s relevant here because it indicates the chipset is designed to work with Intel Optane memory, and the support for PCIe 3.0 x16 implies compatibility with that technology. The mention of PCH being "attached" suggests it’s a dedicated expansion slot, not just a general connection point. So, in short, the "supports x4 mode" means it can handle higher performance scenarios while still being able to connect Optane memory via the PCH interface.
4X mode refers to a compact, short slot within a lengthy PCI-E port. It allows you to fit an M.2 x4 SSD into the same space.
Yes, that's correct. The PCIe slot works with a 3.0 x 16 configuration by default. When you connect an M.2 or SATA expansion card, it switches to a 4-lane setup instead of the 16 lanes. For Gen 3 x 4 cards, it remains at 4 lanes.
