  • The USB 3 or USB 4 port used for the Apollo Twin X USB connection should be natively built into the motherboard.
  • USB 3 adapters (such as PCIe-to-USB 3 expansion cards) have not been extensively tested with Apollo Twin USB.
  • Apollo Twin X USB requires a USB 3.0 SuperSpeed cable when connecting to a USB3 port. USB 2 cables cannot be used.
