BIOS

MSI's X299 Gaming M7 ACK's UEFI is almost identical to that of their other X299 motherboards such as the Gaming Pro Carbon AC. It's very similar to MSI's other motherboards with both and Easy mode and a more advanced mode for experienced overclockers. I found that MSI has auto overlocking up to 5GHz on the 7900X (crazy), but I doubt you can do that without some sort of chiller.

Fan control has been improved over Z270, and now you have the ability to add more temperature sources for reference. MSI's overclocking settings are solid and plentiful, and you still have the ability to work in fixed or dynamic frequency mode.

Software

Software includes MSI's APP Manager (which seems to replace Live Update in some sense), Mystic Light, Gaming APP, DPC Latency Tuner, Command Center, Fast Boot, Live Update 6, RAM Disk, Smart Rool, Super Charger, and X-Boost.
