3.3 Frequently Asked Questions

Question: What type of memory does my motherboard support?
Answer: The motherboard supports UDIMM DDR4 ECC memory. To enhance memory
performance, do not mix memory modules of different speeds and sizes. 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
www.supermicro.com/ResourceApps/BIOS_IPMI_Intel.html. 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.
Warning: Do not shut down or reset the system while updating the BIOS to prevent possible
system boot failure.
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 the 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.
