The GA-Z77X-UD4H is one of GIGABYTE’S
newest Z77 chipset motherboards. Here, you’ll find support for PCI-E 3.0 GPUs
running in SLI or CrossFire, as well as Intel’s 3rd Generation Core processors.
Overclockers will like that the GA-Z77X-UD4H comes with onboard voltage read
points for accurate, real-time information about the processor and memory’s
power consumption. There’s also an onboard BIOS switch, so you can move between
overclocking and regular BIOS settings or you could try out a new BIOS without
losing any of your original settings.

The graphics subsystem looks like this: The
first PCI-E xl6 slot works at full xl6 speed with one card, and it moves to x8
when a second graphics card is connected. The second PCI-E 16 slot runs at x8
speed no matter if one card or two cards are connected. There’s also a third
PCI-E xl6 slot, and it supports PCI-E 2.0 devices. This bottom PCI-E xl6 slot
shares bandwidth with all the PCI-E xl slots and runs at x4, which makes it
useful as a slot for a dedicated PhysX card. Note that the board’s three PCI-E
xl slots will be unavailable if you install any add-on cards to the bottom
PCI-E xl6 slot.
Note
that the board’s three PCI-E xl slots will be unavailable if you install any
add-on cards to the bottom PCI-E xl6 slot.
For memory support, GIGABYTE provides four
DIMM slots that are capable of handling up to 32GB of memory clocked at up to
2,800MHz. The dual channel architecture supports Intel’s XMP memory profiles
for quick setup of optimal memory speeds and timings. For storage connectivity,
you’ll find a total of four 6Gbps SATA ports and four 3Gbps SATA ports.
GIGABYTE utilized a Marvel 88SE9172 chip that adds two 6Gbps eSATA ports to the
rear panel, but these ports will be unavailable if you connect devices to the
SATA ports 6 or 7. There are eight USB 3.0 ports (six on that rear panel, two
internal) and six USB 2.0 ports (all via internal headers).
For
storage connectivity, you’ll find a total of four 6Gbps SATA ports and four
3Gbps SATA ports.
The GA-Z77X-UD4H comes with GIGABYTE’S UEFI
BIOS that provides native support for 3TB hard drives, as well as an
easy-to-use GUI. Support for Lucid Virtu GPU helps to optimize video processing
and media playback with Intel HD graphics, and it lets you switch between
Intel’s HD Graphics and your discrete graphics card. To quick-charge your phone
or tablet, GIGABYTE includes it’s On/Off Charge software that recharges your
mobile devices, even if the PC is turned off.
This board put up benchmark numbers similar
to what we saw with GIGABYTE’S high-end GA-Z77X-UP5 TH, which we reviewed in
the October issue. We saw an overall mark of X3875 in 3DMarkll. Our test
system’s Intel Core i7-3770K delivered a good result of 7.53 points in
Cinebench 11.5. You get a lot of value for your money with the GA-Z77X-UD4H, as
it provides features necessary for both gaming builds and overclocking
enthusiasts.
