- Which CPUs does this B550 board support?
- It supports AMD Ryzen 5000, 4000G and most 3000 series chips on socket AM4. Ryzen 1000 and 2000 are not officially supported on B550.
- Does it support PCIe 4.0?
- Yes, on the main graphics slot and the M.2 slot, but only with a Ryzen 5000 or 3000 CPU. The chipset's own lanes stay at PCIe 3.0.
- Can I install 64GB of DDR4?
- Yes. Four DIMM slots let you run 64GB or more, though check the board's memory QVL for the kit you plan to use.
- Is Wi-Fi built in?
- Usually not on B550 boards at this level. Plan on a wired Ethernet connection or add a PCIe or USB Wi-Fi card.
- How is it different from a B450 board?
- B550 adds PCIe 4.0 from the CPU and generally better power delivery, while B450 is PCIe 3.0 only. B550 also drops support for older Ryzen chips.
- What comes in the box?
- Typically the board, SATA cables, an I/O shield if it is not pre-mounted, and a manual. Cooler and CPU are not included.
- Where is the AM4 DDR4 64G SATA3 M.2 PCI-E4.0 Motherboard cheapest?
