X79 Motherboard Roundup: ASRock, ASUS, Gigabyte

Gigabyte GA-X79-UD5

Although Gigabyte has always made a fine motherboard, its products have occasionally been more subdued than other board makers’ offerings, recently lacking amenities such as onboard power/reset buttons and a UEFI BIOS. With the X79-UD5, those days are apparently over.

The company’s line of X79-based motherboards are the first to feature Gigabyte’s new 3D BIOS, which is based on Gigabyte’s DualBIOS and finally gives users a UEFI in which to tweak and tinker instead of the outdated AWARD BIOS.

The X79-UD5 also sports a big red power button and a reset button, and a clear CMOS button and OC button are on the back I/O panel. The board itself is black with a black and metallic gray color scheme with metallic blue accents. The DIMM slots are color-coded for easy installation, which is always a welcome feature.

The X79-UD5 has eight DIMM slots supporting up to 64GB of quad-channel DDR3-2133 memory. It has six expansion slots, three of which support PCI-E 3.0, and of those three, two can run at x16 when in a dual-CrossFireX/SLI configuration and all three can run at x8 in a three-way graphics setup.

Between the chipset and Marvell, Fresco, and VIA chips, the board has six SATA 6Gb/s (including one eSATA) and six SATA 3Gb/s connectors with support for RAID 0, 1, 5, and 10; four USB 3.0 ports (two of which require an attachment) and fourteen USB 2.0 ports; and two FireWire ports. The back I/O panel also has an optical S/PDIF connector and five audio jacks.


Gigabyte’s X79 motherboards are the first to utilize the company’s new Digital Power Engine for controlling the CPU and memory. The hardware and software tool provides steady power to the CPU and memory under all conditions, giving users better overclocking capabilities. It includes a new 3D Power utility that gives users an attractive graphical interface for adjusting voltage, phase, and frequency.

Speaking of overclocking, Gigabyte built in OC-DualBIOS, which lets users use one BIOS version for overclocking while keeping another stable BIOS separate for if (when) you take your overclock too far; even better, OC-DualBIOS is controllable via a button on the back panel.

The X79-UD5 also feature Gigabyte’s 333 on-board acceleration technology, which promises to speed data transfer over USB 3.0 and SATA, as well as On/Off Charge for quick-charging iOS devices even when the system is powered down.

The rest of the software and utilities we’ve come to expect from Gigabyte are here as well, including EasyTune6, Q-Share, Smart 6, XHD, Cloud OC, and TouchBIOS.

For connectivity out of the box, Gigabyte included a Bluetooth/WiFi card and an antenna for each; the card occupies a PCI slot and connects with one internal header; it’s up to you to find somewhere to mount the two antennae.
