BIOS Settings & Test Setup

BIOS Settings

The UEFI BIOS Utility of the MSI Z77 MPower was identical to the MSI Z77-GD65 and navigating it was a no-brainer. We did appreciate the large navigation tabs on both sides of the UI which helped categorize the different functions of the BIOS.

The MSI UEFI BIOS utility has a pleasant black-and-blue hue and we like its well-organized menu layout. The temperature readings for the CPU and motherboard were very helpful especially during our overclocking exercise.

While most enthusiast class boards these days have way too many overclocking related settings, we've decided to compile the available voltage settings of the various Z77 boards we've tested. As you'll see later in our overclocking efforts with the MSI Z77 MPower, we decided to manually adjust the voltage of the CPU PLL to determine how high we can push the CPU Base Frequency. In the case of this particular board, base frequency values can be adjusted by 10KHz for finer tweaking.
