3.3 Frequently Asked Questions

Question: What type of memory does my motherboard support?
Answer: The X11SAT/X11SAT-F motherboard supports up to 64 GB of DDR4 ECC/Non-ECC
UDIMM memory up to 2133MHz. See Section 2.4 for details on installing memory.
Question: How do I update my BIOS?
Answer: It is recommended that you do not upgrade your BIOS if you are not experiencing
any problems with your system. Updated BIOS files are located on our website at http://www.
supermicro.com. Please check our BIOS warning message and the information on how to
update your BIOS on our website. Select your motherboard model and download the BIOS
file to your computer. Also, check the current BIOS revision to make sure that it is newer
than your BIOS before downloading. You can choose from the zip file and the .exe file. If
you choose the zip BIOS file, please unzip the BIOS file onto a bootable USB device. Run
the batch file using the format FLASH.BAT filename.rom from your bootable USB device to
flash the BIOS. Then, your system will automatically reboot.
Question: Why can't I turn off the power using the momentary power on/off switch?
Answer: The instant power off function is controlled in BIOS by the Power Button Mode
setting. When the On/Off feature is enabled, the motherboard will have instant off capabilities
as long as the BIOS has control of the system. When the Standby or Suspend feature is
enabled or when the BIOS is not in control such as during memory count (the first screen
that appears when the system is turned on), the momentary on/off switch must be held for
more than four seconds to shut down the system. This feature is required to implement the
ACPI features on the motherboard.
