X79 Motherboard Roundup: ASRock, ASUS, Gigabyte

ASRock X79 Extreme6/GB

The ASRock X79 Extreme6/GB is actually rather new to ASRock’s X79 lineup, but it sports the sexy black, silver, and gold (capacitors) look that we’ve seen from the company before.

The board supports the new socket LGA 2011 Intel CPUs and provides 12+2 Digi Power power phase, up to 64GB of DDR3-2400MHz (OC) system memory, and plenty of expansions options.  You can run up to 4-way SLI or CrossFireX with x8 connections. There’s also a PCI-E x1 slot, a pair of PCI slots, and note that three of the x16 slots are PCI-E 3.0 capable (though Intel hasn't specifically validated the platform yet).

There are five SATA 6Gb/s ports via the chipset and an ASMedia USB 3.0 chip, as well as four SATA 3Gb/s ports. Four USB 3.0 ports dot the back panel, while internal headers offer up another two, as well as six USB 2.0 ports. The motherboard itself has power and reset buttons, a Dr. Debug LED and a Clear CMOS button conveniently located on the back panel.

Other ports and connectors include eSATA3, seven audio jacks, FireWire, LAN, PS/2 keyboard and mouse ports, coaxial and optical S/PDIF outs, and an IR header.


There are plenty of extras in the box, including 2- and 3-way SLI bridges, a handful of SATA cables and screws, and a front USB 3.0 panel, but ASRock also included a Game Blaster. The palm-sized Game Blaster pops into a PCI-E x1 slot and has four mini jacks, a LAN port, optical and coaxial S/PDIF, and front panel audio and HDMI/S/PDIF headers on the back. In addition to providing Creative Sound Core3D 7.1 HD sound, the Game Blaster supports LAN teaming when used with the onboard LAN port.

ASRock bundled a lot of tools and utilities in the X79 Extreme6/GB, including Instant Boot, Instant Flash, APP Charger, SmartView, and Crashless BIOS, and of course, there’s the X family of tools (XFast LAN, XFast RAM, and XFast USB) that let you easily optimize the performance of each.

Overclockers have some toys to play with, too. The board includes the ASRock Extreme Tuning Utility, X-FAN (a fan over the southbridge that automatically kicks on only when needed), and Hybrid Booster, which is a suite of utilities designed to prevent you from overclocking your system to death.
