The Ultimate MSI Z270 Gaming M7 Motherboard Build Guide (Page 5)

UEFI Overview


MSI's UEFI is called CLICK BIOS 5 and offers two modes of operation. An "EZ Mode" is for novice users who have never really entered a BIOS before, and an "Advanced" mode is for more experienced users. To switch between the two BIOS types, press F7 or click the top-center portion of the screen. MSI's UEFI allows both mouse and keyboard selection of most settings, and you have the option of changing boot priorities through the bar below live system status in EZ mode, or through a traditional menu in Advanced mode. Hardware Monitor (fan control), can also be accessed through either of the two modes.


Hardware Monitor offers excellent control over fan speeds and is very easy to setup. I will dive into the details of Hardware Monitor in the next section of this guide. The settings menu in advanced mode allows you to control advanced system settings, such as disabling ports or configuring integrated graphics.


Board Explorer is a neat feature of the UEFI, and hovering over a port or object will bring up details. Board Explorer is capable of recognizing individual USB devices and even the SPD of the individual DIMMs, so you know exactly what is connected to your motherboard.


Other than overclocking or setting up fan control, most people enter the UEFI/BIOS to choose the boot order of their drives and devices. If you are installing Windows 10, I would stick with UEFI installation mode. Once you have installed Windows 10, you will notice that a new boot device pops up called Windows Boot Manager, and that is what you want as your first boot device. Windows 10's installation can communicate with the UEFI and makes things quite simple.


Overclocking can be done automatically through the GAME BOOST knob at the top left-hand corner of the screen, or through manual overclocking in the OC menu. One nifty feature of MSI's UEFI is the list of changes made when you try to exit.

Manually Updating the BIOS


I made a nice little step-by-step image for you to follow to manually update the UEFI. There are many ways to update the UEFI, but I prefer using the UEFI's built-in BIOS flashing tool. You can recover a corrupt UEFI by using MSI's USB Flashback+, and the manual has good instructions on using that feature. For manual flashing, you can download MSI's latest UEFI/BIOS version from their official website and load it onto a USB drive. Then you will enter the UEFI, click on M-Flash, and the system will reboot and enter into M-Flash mode.

In M-Flash, the utility will scan your USB stick for a BIOS file and ask you if you would like to update using the file. Click yes, and the system will attempt to flash the UEFI. Do not, no matter what, interrupt this process. If the flash is interrupted the BIOS will become corrupted, and you will have to use USB Flashback+. One thing I always like to do after a flash is load optimized defaults and then save and exit the BIOS and proceed as usual.
