Asus ROG B550-F doubts

[dja2k]

Can any one with this motherboard clarify if using both M.2 slots, will video card still run at full PCIE 4.0 specs? Also how many sata ports do I loose, 2 or 4? Thanks

Yes GPU will run at full bandwidth with 2x M.2s. You lose 2 ports.

Awesome, thanks 👍

For reference, the manual has this info.

Yeah I know, but was more curious about the PCIe full bandwidth. Never built one using 2 M.2 slots occupied.

The manual shares that info. It states on the specs table as well later in the document what is shared. In your case, you lose a pair of sata ports and some pcie lanes that are attached to CHIPSET PCIe. The primary gpu slot is connected via the cpu and doesn't lose a thing.
