GIGABYTE Z77X-UD5H Review – Best Z77 Motherboard Feature Wise

Enthusiast who’s looking for a solid performing board and highly durable for their new Ivy Bridge platform, the Gigabyte GA-Z77X-UD5H is the best Z77 motherboard you can have. Gigabyte is well-known for years as they produce some of the toughest board and now giving you another state of the art motherboard loaded with new features.

The Gigabyte GA-Z77X-UD5H Is Built For Absolute Toughness

The Gigabyte GA-Z77X-UD5H belongs to Ultra Durable 4 series that built for its toughness. With this features you got a complete protection from your PC. This includes a double size copper PCB for optimum signal transfer at the same time power efficient and cooler that gives you more tolerance for overclocking.

In addition to that is the new Glass Fabric PCB, High ESD protection IC, Dual BIOS, Anti Surge IC, All Solid Japanese caps and lower RDS MOSFETs. As a result, rock solid boards that almost a failure free system. Gigabyte manages to put the board in a well package to protect it from any mishandling during shipping.

The Gigabyte GA-Z77X-UD5H Is Loaded With More Features

The Gigabyte GA-Z77X-UD5H is loaded with the latest state of the art features. The board is equipped with all digital power in four main zones such as the CPU, Memory, HD Graphics and VTT to deliver an optimum performance. Gigabyte introduces the 3D Power Voltage Control, 3D Power Phase Control and 3D Power Frequency Control. This aims to supply the main areas of the system to get the best overclock possible with superb stability.

The new Z77 7-series chipset supports the PCIe 3.0 GPU hence called Gen3, this improves the new generation graphics display by doubling the existing PCIe 2.0 bandwidth. This also includes a better integrated GPU display through the HD 4000 video coming from the new Ivy Bridge processor. A faster video conversion is expected via QuickSync technology.

Another great feature with the new 7-series chipset is the Universal LucidVirtu MVP. This feature firstly seen in the Z68 chipset, the new improved MVP version promises a better performance that eliminates the tearing effects caused by a mismatch between the display and the GPU.

Using the USB 3.0 port is the fastest and most convenient way to transfer files. Having the latest technology called the SuperSpeed USB 3.0 with Gigabyte 333 Onboard acceleration; it boosts the transfer speed up to 3 times. The results were stunning, as it seems like you’re transferring it in a SATA 6GB/s speed.

Let’s Take A Look At The Gigabyte GA-Z77X-UD5H

The Gigabyte GA-Z77X-UD5H looks great in all black PCB design with blue beefy heatsink on the chipset and voltage regulator to withstand any heat even at stressed conditions. The CPU socket leaves more space if you wish to install an oversize CPU cooler. Beside the CPU socket is the mSATA port, this is limited to SATA 3GB/s and works great if you want to take advantage of Intel’s Smart Response Technology. However, we have to take note that, it will disable two of your SATA II ports when enabled.

A typical 4-DIMM slot is provided in all black colors that come in duo to avoid confusion when installing the correct pairing. This supports up to 32GB of 2400MHz DDR3 memory sticks. The two PCIe 16x slots are nicely space with two PCIe 1x in between that provides proper airflow when both cards are being populated; the third one is closed with the Legacy PCI slot.

The UD5H is geared with on-board buttons that makes it very handy when testing the board. This includes the power, reset and the CMOS clear, there’s also goes the LED Debug display beside the power switch.

There are eight SATA connectors available on board; four of them are SATA 3GB/s in black and two SATA 6GB/s in white coming from the Z77 chipset, the other two SATA 6GB/s is being controlled by Marvell 88SE9172 chip. An additional SATA power connector is provided at the edge of the board that aim to supply the PCIe x16 card. Beside of it are series of headers for the front panel control LED, USB 2.0 and Firewire.

Moving on the back panel you can see a plenty of possibilities for you to take advantage of the new HD 4000 graphics provided by the Ivy Bridge processor, there’s the 15-pin VGA D-sub, DVI, HDMI and Display port. A total of six USB ports available in which four of these are SuperSpeed USB 3.0 and two USB 2.0. There’s also the eSATA, FireWire, two Gigabit LAN and six audio ports with optical SPDIF out.

Overclocking The Gigabyte GA-Z77X-UD5H

To find out how good the board performs it was put to test to see how far it can overclock the Ivy Bridge Core i7-3770K. The processor has a speed of 3.5GHz, the default setting for base clock is at 100MHz and the multiplier is set to x35. Hitting the turbo mode you can easily get a 3.9GHz speed; the system simply increased the multiplier by x39.

The GA-Z77X-UD5H is equipped with the Easy Tune 6 for easily overclocking your processor. By taking the Level 2 pre-set frequencies you’ll arrive at 4.443GHz with the base clock set to 103.33MHz and the multiplier at x43, the system runs smoothly without having any problems with an increase of 944MHz on top of it.

Hitting the preset Level 3 you got 4.693GHz after rebooting, the Bclk is automatically set to 104.3MHz and the multiplier is at x45. Although it fail to reach the 4.8GHz, the results was nearly 4.7GHz gaining a fairly 1.2GHz that improves further the system performance.


The Gigabyte GA-Z77X-UD5H is a solid performer; once you reach the final OC speed you got a blazing fast performance. Ivy Bridge processor reaches lower OC compare to Sandy Bridge. However, frequency is not always been the case for faster performance. The reason behind this is that the Ivy’s requires lower voltage.

If you’re into higher overclocking speed that goes beyond 5GHz you can always use the 2600K/2700K, this is where the beauty of this board lies as it fully backward compatible. If you want to take advantage of low power consumption, high efficient, fast transcoding and the new HD 40000 graphics the Core i7 3770K is a wise choice.

The board is currently available at $180, cheaper than the ASUS P8Z77-V Deluxe, considering the features it offers are almost the same but, a bit shorter on the OC side. On the other hand, the GA-Z77X-UD5H has a tougher design for optimum durability. By sacrificing some of its USB port to trade with additional video port is a wise decision for Gigabyte, making it a better choice for the best z77 motherboard.
