The maximum system memory multiplier is 41.33 (4133 MHz). The only difference is that the CPU upgrade option brings out a drop down menu that is listing the end frequency of the CPU, probably for users who are not aware that the CPU clock ratio multiplied by the base clock is the exact same thing. Strangely, there is both a manual control of the CPU's clock ratio and a 'CPU upgrade' option, both of which are virtually doing the same exact thing. The frequency submenu allows for the adjustment of the CPU and memory clocks and ratios, including FCLK. The first tab is the M.I.T., by far the most complex section of the BIOS, as it includes all of the frequency, memory and voltage settings of the motherboard. The 'classic' or advanced mode reveals the entirety of the motherboard's capabilities and options. The few options that a casual user might need, such as boot sequence and fan speed adjustments, are accessible from this page.

The 'easy' mode can be initiated by clicking at the appropriate button, reducing the entirety of the BIOS into a single screen that mostly provides system information and monitoring.

Oddly enough, GIGABYTE has the advanced mode enabled by default for users that first enter the BIOS of these motherboards. As such, we are presenting them together in this page. There are very few exceptions, such as the RGB LED support for the former (one extra BIOS option and one simple app). At the time of this review, the Gigabyte GA-Z170X-Designare and the GA-Z170X-Ultra Gaming are sharing virtually the same BIOS and Software.
