Gigabyte GA-EX58-UD5 X58 Motherboard Review

Subject: Motherboards
Manufacturer: Gigabyte

Introduction and Specifications

The X58 desktop chipset exploded onto the scene last year triumphantly proclaiming itself the lone chipset solution to support the 45nm Intel Core i7 processor family. Not only does this chipset flex its muscles with the equally-impressive i7 CPUs, but it also struts around the playground with dual x16, triple x16-x16-x8, or quad x8 PCI Express 2.0 graphics card support.

Many vendors have taken advantage of the X58 chipset craze, and Gigabyte is no exception.  Their GA-EX58-UD5 offering is targeted toward PC enthusiasts and gamers with aspirations for overclocking their components. Check out the specs list below to find out more.

    support for Win9X/ME. If some vendors still has Win9X/ME drivers
    available, we will publish on website.
Note (Note
1) Due to Windows Vista/XP 32-bit operating system limitation, when
more than 4 GB of physical memory is installed, the actual memory size
displayed will be less than 4 GB.

(Note 2) For Windows Vista/XP 32-bit operating system only.

(Note 3) For optimum performance, if only one PCI Express graphics card
is to be installed, be sure to install it in the PCIEX16_1 slot; if you
are installing two PCI Express graphics cards, it is
recommended that you install them in the PCIEX16_1 and PCIEX16_2 slots.

(Note 4) The PCIEX8_1 slot shares bandwidth with the PCIEX16_2 slot.
When PCIEX8_1 is populated with a PCI Express graphics card, the
PCIEX16_2 slot will operate at up to x8 mode.

(Note 5) A JMB322 chip supports two SATA 3Gb/s connectors, so the four
SATA 3Gb/s connectors are divided into to two pairs: GSATA2_0 and
GSATA2_1 as a pair and GSATA2_2 and GSATA2_3 as a pair. (Refer to
Chapter 2, "Integrated Peripherals" and Chapter 5, "Configuring SATA
Hard Drive(s)," for how to enable the Smart Backup function.)

(Note 6) Whether the CPU/system fan speed control function is supported will depend on the CPU/system cooler you install.

(Note 7) Available functions in EasyTune may differ by motherboard model.
