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 under UEFI Shell?
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. To update
your BIOS under the UEFI shell, please unzip the BIOS file onto a USB device formatted
with the FAT/FAT32 file system. When the UEFI shell prompt appears, type fs# to change
the device directory path. Go to the directory that contains the BIOS package you extracted
earlier. Enter flash.nsh BIOSname#.### at the prompt to start the BIOS update process.
Reboot the system when you see the message that the BIOS update has completed. Refer
to Appendix D UEFI BIOS Recovery and/or readme file for more information.
Warning: Do not shut down or reset the system while updating the BIOS to prevent possible
system boot failure.
Note: The SPI BIOS chip used on this motherboard cannot be removed. Send your
motherboard back to our RMA department at Supermicro for repair. For BIOS Recov-
ery instructions, please refer to the AMI BIOS Recovery Instructions at http://www.
supermicro.com/support/manuals.
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.
