M.2 Sockets
This motherboard has three M.2 sockets. M.2 was formerly known as Next Generation
Form Factor (NGFF) and serves to replace mini PCIe. M.2 allows for a variety of card sizes,
increased functionality, and spatial efficiency. Refer to the table below for more information.
Sockets
M.2-P1 (from PCH)
M.2-P2 (from PCH)
M.2-C1 (from CPU)
SATA Ports
Six Serial ATA (SATA) 3.0 connectors (I-SATA 0 - 5) are supported on the motherboard. These
I-SATA 3.0 ports are supported by the Intel Z790 PCH chip (supports RAID 0, 1, 5, and 10).
SATA ports provide serial-link signal connections, which are faster than the connections of
Parallel ATA.
Note: For more information on the SATA HostRAID configuration, please refer to the
Intel SATA HostRAID user's guide posted on our website at
support/manuals/.
Front Panel Audio Header
A 10-pin Audio header at AUDIO FP is supported on the motherboard. This header allows
you to connect the motherboard to a front panel audio control panel, if needed. Connect an
audio cable to the audio header to use this feature (not supplied). Refer to the table below
for pin definitions.
