Frequently Asked Questions
Which CPUs are compatible?
This board supports AMD Ryzen 3000 and 5000 Series (AM4 socket). Ryzen 5000 Series (e.g. Ryzen 5 5600X, Ryzen 7 5800X) may require a BIOS update — most units ship with an updated BIOS already applied.
Does it support PCIe 4.0?
Yes — the primary M.2 slot and x16 GPU slot run at PCIe 4.0 speeds when paired with a Ryzen 5000 Series CPU. PCIe 4.0 drops to 3.0 with Ryzen 3000 Series.
Will my existing DDR4 RAM work?
Yes, as long as it's DDR4. The board supports speeds from DDR4-1866 up to DDR4-4600+ (OC). DDR5 is not supported.
What does "Renewed" mean?
Renewed means the board has been professionally inspected, tested, and restored to full working condition. It may show minor cosmetic wear but is functionally equivalent to new.
Does it have onboard Wi-Fi?
No — the B550-A PRO does not include built-in Wi-Fi. You'll need a separate PCIe or USB Wi-Fi adapter if wireless connectivity is required.
What's included in the box?
Motherboard, I/O shield, SATA cables, user manual, and driver disc. CPU, RAM, cooler, and GPU are not included.
