You’ll find no SATA 3Gbps ports on this board; instead, there are six total SATA 6Gbps ports (two powered by the chipset, four by the ASMedia chip). The back I/O panel has five USB 2.0 ports in addition to six USB 3.0, and a front panel header supports another two USB 3.0 ports. The rest of the ports on the back panel include a PS/2 port, eSATA3 port, FireWire, HDMI, DisplayPort, optical SPDIF, dual LAN, five audio jacks, and a clear CMOS button.
One of the USB ports is the Fatal1ty Mouse Port, which works in conjunction with the Fatal1ty F-Stream software, a utility that lets you overclock and tweak hardware settings including RAM speeds and Fan Control. With a USB mouse plugged into the special port, users can adjust the mouse polling rate from 125Hz to 1,000Hz using F-Stream.
Other ASRock software and utilities onboard include the ASRock OMG (Online Management Guard) Internet curfew service; Rapid Start and Smart Connect utilities to speed boot times and enable email receipt and Web page refreshes while the system’s asleep; CPU EZOC for easy overclocking; ASRock’s XFast 555 technology to boost memory, LAN, and USB performance; and more.
For accessories, ASRock provided a manual, quick installation guide, installation disc, I/O shield, six SATA cables, rear USB 3.0 bracket, front USB 3.0 panel, SLI bridge, a pair of power cable adapters, and a smattering of screws.
