Gigabyte Z97X-Gaming 7 Motherboard Review

Firstly, we are pleased to report that our Leetgion Hellion mouse worked to its usual standard in the Gigabyte Z97X-Gaming 7 motherboard’s UEFI BIOS.

Gigabyte's DualBIOS UEFI implementation used on the Z97X-Gaming 7 is identical to that used on the Z97X-UD5H-BK motherboard, with the exception of a different colour theme. As such, pictures from the previous review are used and our analysis and recommendations are largely identical, with the point of reference adapted to the requirements of gaming users.

Gigabyte greets users with an entry page that resembles the Windows Metro UI. Tiles provide users with quick access to certain features and settings.


A UI based around Gigabyte's old style of BIOS is present on the Z97X-Gaming 7 motherboard. Users with experience in the old interface may welcome the BIOS-style layout.

UEFI-Skin frequency3 frequency-2 frequency-1

Upon entering the 1920×1080 (dependent upon your monitor's resolution) UEFI, Gigabyte opens the frequency page. The interface packs large amounts of information into a single screen by virtue of its 1920×1080 resolution. Voltages, frequencies and other monitoring parameters are consistently scattered around the outside of each page.

A number of speed parameters and performance boosts can be selected via the Frequency page and its subsections.

The Z97X-Gaming 7 uses an orange skin by default, although the theme colours can be adjusted via the UEFI.

Frequency and timings configurations can be adjusted via the Memory section. Gigabyte includes pre-set profiles tailored for high-spec RAM kits by overclocking professionals such as HiCookie.

voltage-5 voltage-4 voltage-3 voltage-2

Power and voltage settings can be adjusted in the relevant subsection. Some of the parameters, such as CPU VRIN Loadline Calibration, open a graphical display to assist a user in making an appropriate choice.

Oddly, Gigabyte situated the all-important CPU voltage controls in the second column on the Voltage subsection, not the first. If one does not like the slider approach of applying voltages, users are able to key in the relevant values.

HW-monitoring-3 HW-monitoring-2 HW-monitoring-1

Fan and warning settings can be accessed via the PC Health Status column of the Miscellaneous section. Fan speed controls can be set to a user's preference, albeit with a limited range of input.

Gigabyte uses a drop-down list to outline the relevant fan speed curves, which is a less user-friendly approach than the graphical interface used by competing motherboard vendors.

BIOS-Home-3 BIOS-Home-2 BIOS-Home-1 BIOS-custom-1

The Home section provides an area where users are given a degree of freedom as to the interface's layout. By default, key component parameters are displayed on the Home page, but this layout can be tweaked to a user's preference. And if you'd rather not tweak the interface, Gigabyte allows you to create four custom pages from scratch.

The Recent section displays recently used settings while the Favourites tab can provide quick access to frequently used parameters.

OC-Profiles OC-Profiles-2

Up to eight OC profiles can be saved to the motherboard's internal memory, while many more and more can be exported or imported via USB.

We noticed that, for some reason, Gigabyte's UEFI likes to overwrite saved settings profiles when trying to load them. I loaded my stock-speed saved profile, only to find that it had been overwritten by the current settings.

This is a fundamental error that will frustrate many users, especially those who have spent time fine-tuning their overclocking profile only to see it overwritten.

BIOS-preferences-2 BIOS-tools-1

Control adjustments for the UEFI and the Q-Flash BIOS updater can be accessed via the Save & Exit section. I would prefer Gigabyte to have given the many of the control parameters their own section titled ‘Settings' to make them easier to spot in the UEFI. Save & Exit typically implies saving and exiting, not adjusting control options and updating the BIOS.

Some useful additions to Gigabyte's UEFI are the ability to change the visual theme, background wallpaper, and resolution.

BIOS-tools-2 BIOS-tools-1

The Q-Flash updater is able to access folders in a USB flash drive, allowing users to manually seek a BIOS file.

Gigabyte has made some key improvements on its Z97 UEFI over the version used on many of the company's Z87 boards. The most noteworthy upgrade comes in the form of organisation; Gigabyte has optimised the layout to make sifting through BIOS settings and sections a simpler task. It is indeed a more pleasant experience working in the Z97X-Gaming 7 motherboard's UEFI, although there is still clear room for improvement.

The use of a Full HD, 1920×1080 resolution is excellent. Additional information relating to operational recordings can be displayed on a page without interfering with the parameters that users intend to tweak. And there's also the old style of BIOS for people who have extensive experience with Gigabyte's motherboards from previous generations.

There are still a few issues relating to overlapping content and generally poor layout. Many parameters for frequency and voltage are repeated multiple times causing the UEFI to seem more crammed than it actually is. Fan speed control is also a negative aspect; a list outlining arbitrary (to many people) values and units is less user-friendly than a graphical interface displaying the fan speed curves.
