Frequently Asked Questions
Does the B550 Tomahawk support Ryzen 5000 CPUs out of the box?
It supports AMD Ryzen 5000 Series and 3rd Gen Ryzen processors, with MSI noting that future Ryzen processors require a BIOS update. Confirm the shipping BIOS revision on the listing before pairing it with a newer chip.
How much RAM can this motherboard handle?
It supports dual channel DDR4 up to 128 GB, with rated speeds up to 4866 MHz across its four DIMM slots.
Does it have 2.5 Gbps networking?
Yes. It uses on-board dual LAN: one 2.5G port plus a separate Gigabit port, so you can run two wired connections at once.
Is there PCIe 4.0 and a fast M.2 slot?
Yes. The board runs PCIe 4.0 for graphics and includes a Lightning Gen 4 M.2 slot covered by an M.2 Shield Frozr heatsink to keep drive temperatures down under load.
Can I use the HDMI and DisplayPort outputs?
Only with a Ryzen processor that has integrated graphics, such as an AM4 APU. Ryzen 5000 X-series chips have no iGPU, so those builds need a discrete graphics card.
