Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.
Firmware
Like other MSI BIOS configurations, the Pro B660-A starts you out with an informational EZ Mode that allows editing of some high-level functions, including enabling XMP profiles, adjusting 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 mostly 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, which lets you download 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. Though updates should fix this down the road, it’s worth noting that you cannot overclock the system with the version I had. But serious overclockers will want to do their tweaking in the BIOS anyway.
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 has been updated, as noted in the table below. We use the latest non-beta motherboard BIOS available to the public unless otherwise noted. The hardware we 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 G.Skill sent us a DDR5-5600 (F5-5600U3636C16GX2-TZ5RK) memory kit for launch day testing.
