Physical connector counts do not guarantee simultaneous use. Check processor and lane-sharing limits in the specification.

The single M.2 position supports SATA and PCIe storage, with processor-dependent limits. The listed Athlon and A-series processors are restricted to M.2 SATA. Use V2 documentation rather than the original DS3H model.
