Like all ASUS boards we've looked at recently, the M5A99X EVO carries with it the UEFI BIOS. Unlike the ROG boards from ASUS, when you go into the BIOS here you're greeted with EZ Mode instead of advanced mode. From here you can do a few things, but nothing too major. The fun really begins when you get out of EZ Mode and get into Advanced Mode.
In advanced mode you won't find anything too out of the ordinary. The overall BIOS looks pretty similar too other UEFI BIOSs we've seen from ASUS. The main section you'll probably find yourself in is the AI Tweaker section which lets you do everything related to overclocking. Apart from that, most of the other areas are of course fairly self-explanatory as you can clearly see what's on display.
