To give you a sense of the Firmware, we’ve gathered screenshots showing most BIOS screens.

The BIOS on these Supermicro boards do the job and have improved since they first came out. However, they still aren’t as refined as the others. It still feels like a server BIOS, in that the look is relatively simple. In EZ Mode, you’re able to get an idea of where the system stands and change a couple of options. Using the Advanced mode, you’ll see headers across the top (Main, Overclocking, Advanced, H/W Monitor, Boot, Save & Exit and BIOS Update) with options listed below.

Although the BIOS works just fine, POST takes a lot longer than most consumer-facing motherboards. The way your selection is highlighted works differently, so it takes a bit of getting used to. In essence, you have two things highlighted at once and have to hit enter to select the field to get it to move. Typically, the highlight follows the cursor without making a selection.


Supermicro has the SuperOBooster application on the software front, an all-in-one monitoring and adjustment tool designed for its motherboards. The software is easy to read and maneuver around and controls the CPU and memory, fans, voltage, and updating the BIOS. SuperOBooster does a good job of presenting system information as well as being simple to use.

Test System

As of March 2021, we’ve updated our test system to Windows 10 64-bit OS (20H2) with all threat mitigations applied. On the hardware front, we’ve switched to all PCIe 4.0 components. We upgraded our video card to an Asus RTX 3070 TUF Gaming and the storage device to a 2TB Phison PS5-18-E18 M.2. We’ve also updated the games to F1 2020 and Far Cry: New Dawn, along with the hardware changes. We use the latest non-beta motherboard BIOS available to the public unless otherwise noted (typically during new platform launches). The hardware used is as follows:
