3-3 Frequently Asked Questions
Question: What type of memory does my motherboard support?
Answer: The C7X99-OCE supports up to 64GB of unbuffered Non-ECC/
ECC DDR4. See Section 2-4 for details on installing memory.
Question: How do I update my BIOS?
Answer: We do NOT recommend that you upgrade your BIOS if you are
not experiencing any problems with your system. Updated BIOS les are
located on our website at http://www.supermicro.com/support/bios/.
Please check our BIOS warning message and the information on how
to update your BIOS on our web site. Select your motherboard model
and download the BIOS ROM le to your computer. Also, check the cur-
rent BIOS revision to make sure that it is newer than your BIOS before
downloading. You may choose the zip le or the .exe le. If you choose
the zipped BIOS le, please unzip the BIOS le onto a bootable device
or a USB pen/thumb drive. To ash the BIOS, run the batch le named
"ami.bat" with the new BIOS ROM le from your bootable device or USB
pen/thumb drive. Use the following format:
F:\> ami.bat BIOS-ROM-lename.xxx <Enter>
Note: Always use the le named “ami.bat” to update the BIOS,
and insert a space between "ami.bat" and the lename. The BI-
OS-ROM-lename will bear the motherboard name (i.e., C7X99)
and build version as the extension. For example, "C7X99.115".
When completed, your system will automatically reboot.
If you choose the .exe le, please run the .exe le under Win-
dows to create the BIOS ash oppy disk. Insert the oppy disk
into the system you wish to ash the BIOS. Then, boot the sys-
tem to the oppy disk. The BIOS utility will automatically ash
the BIOS without any prompts. Please note that this process
may take a few minutes to complete. Do not be concerned if
the screen is paused for a few minutes.
When the BIOS ashing screen is completed, the system will
reboot and will show “Press F1 or F2”. At this point, you will
need to load the BIOS defaults. Press <F1> to go to the BIOS
setup screen, and press <F9> to load the default settings. Next,
press <F10> to save and exit. The system will then reboot.
Attention! Do not shut down or reset the system while updating
the BIOS to prevent possible system boot failure!
