Table 1: When only one of U2_32G and M2M_32G is populated
Due to the limited number of lanes provided by the Chipset, the availability of the SATA connectors may be
affected by the type of devices installed in the U2_32G and M2M_32G connectors. The following tables provide
details on the availability of the SATA connectors when one or both of the U2_32G and M2M_32G connectors
are populated.
When M2M_32G is installed with a SATA-based SSD and U2_32G is empty, the SATA3 0 connector becomes
unavailable.
Installation Notices for the U2_32G, M2M_32G, and SATA Connectors:
