Firmware

Like the other MSI BIOS configurations, you start with an informational EZ Mode that allows editing some high-level functions that enable XMP profiles, adjust fan speeds, and more. The main menu is informational up top, while the bottom two-thirds is where the adjustments happen. You select the section you want on the left or right sides, and the details show in the middle. You don’t have to dig down several screens to reach the overclocking options as they are chiefly found on the main page. Some digging is inevitable, but overall we find this BIOS full of options and easy to read and get around.

Software

For software, the theme these days is to place a lot of the functionality in one program. MSI’s take on this is called Dragon Center software. This application allows you to download all or individual applets. Some of the programs include Mystic Light (RGB control), LAN Manager, User Scenario (overclocking, monitoring, and fan control), Super Charger, MSI Companion (help record games), and many more.

Test System / Comparison Products

We’ve updated our test system to Windows 11 64-bit OS with all updates applied. We kept the same Asus TUF RTX 3070 video card from our previous testing platforms but updated the driver to version 496.13. Additionally, our game selection was updated, as noted in the table below. We use the latest non-beta motherboard BIOS available to the public unless otherwise noted. The hardware used is as follows:

EVGA supplied our Supernova 850W P6 power supply (appropriately sized and more efficient than the outgoing 1.2KW monster we used) for our test systems, and GSkill sent us a fast and good-looking DDR5-5600 (F5-5600U3636C16GX2-TZ5RK) memory kit for launch day testing.
