Gigabyte Z68X-UD5-B3 Motherboard

Introduction

Gigabyte released 11 motherboard models based on the new Intel Z68 chipset. With prices ranging from USD 120 to USD 350, there is a model for any kind of user. Let’s take a look at one of the most high-end models, the Z68X-UD5-B3, which can be bought today for USD 270.

The Intel Z68 chipset is basically a P67 chipset with two new features added. First, the Intel Smart Response Technology (SRT), allows you to speed up disk performance by using an SSD unit as a cache unit for your conventional (i.e., mechanical) hard disk drive. This technology works by storing in the SSD the programs and data you access the most.

The second technology that was added is a video connection between the CPU and the chipset, called FDI (Flexible Display Interface). This connection was previously available on the H67 and similar chipsets but not on the P67 chipset. Socket LGA1155 processors have an integrated video processor, but the P67 chipset won’t allow you to use it since it is targeted to consumers that will have a physical video card. With the Z68, the use of integrated video processor is possible if the motherboard manufacturer added video connectors on the motherboard. This way, Intel won’t be releasing an “H68” chipset.

The big reason for this change was that Intel licensed a software from Lucidlogix called Virtu, which allows the computer to dynamically switch video cards depending on what you are doing with your computer. In a typical scenario, this software will make the system use the CPU’s integrated video engine when you are not playing games, turning your add-on video card completely off, and then turning on your add-on video card and turning off the CPU integrated video when you run games. By keeping your video card completely turned off when you are not playing games, you can save a lot of energy. For this feature to be available on a given Z68 motherboard, the motherboard manufacturer must have licensed the Virtu software.

The Gigabyte Z68X-UD5-B3, however, doesn’t support Virtu, mainly because it doesn’t have video connectors. On the Gigabyte motherboard line-up, only the models that have an “H” on their product name have video connectors and, thus, support the Virtu technology. Unfortunately, Gigabyte decided to add support to the Virtu technology only on their entry-level Z68 motherboards, because only these models have video connectors. It is a pity that the most high-end models from this manufacturer don’t come with support for Virtu, as we believe high-end users are the ones that would benefit the most from it.
