ASRock Fatal1ty Z77 Professional

First up is the Fatal1ty-endorsed ASRock Z77 Professional, a fine-looking board sporting a black and red color scheme, set off by the gold capacitors dotting the PCB with the Fatal1ty logo emblazoned upon the southbridge heatsink. The heatpipes around the CPU socket are wrapped in black metal heatsinks that are reminiscent of an M16’s barrel grip.

Like all of the other boards in our roundup, the ASRock Z77 Professional supports socket 1155 2nd- and 3rd-generation Intel CPUs, and it also boasts a Digi Power VRM design and 16+8 digital power phases, and it can handle up to 32GB of DDR3-2800 (OC) dual-channel RAM over its four DIMM slots.

Though Intel's integrated graphics are nice for pedestrian tasks, the ASRock Z77 Professional is built for graphics expansion with two PCI-E 3.0 x16, a PCI-E 2.0 x16, a pair of PCI-E 2.0 x1 slots, and two PCI slots with support for up to four-way CrossFireX and SLI, with dual cards running at x8 each.

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.
