Universal Serial Bus (USB)
The motherboard supports up to 8 USB 2.0 ports and 2 USB 3.0. The port arrangement
is a follows:
Four USB 2.0 ports are implemented with stacked back panel connectors (black)
Four USB 2.0 front panel ports are implemented through two dual-port internal
headers
Two USB 3.0 front panel ports are implemented through one dual port internal
header.
All 8 USB ports are high-speed, full-speed, and low-speed capable.
NOTE:
Computer systems that have an unshielded cable attached to a USB port may
not meet FCC Class B requirements, even if no device or a low-speed (sub-channel)
USB device is attached to the cable. Use shielded cable that meets the requirements for
high-speed (fully rated) devices.
SATA Support
The board provides four 3 Gb/s SATA connectors, which support one device per

NOTE:
By default the SATA mode is set to AHCI in the BIOS to improve system

AHCI drivers. Both Microsoft Windows Vista and Microsoft Windows 7 include the

RAID drivers using the F6 switch in the operating system installation process. It is
advised to install the latest AHCI drivers to improve system performance.
