Step 2: Disabling Mirror Mode, ADDDC Sparing*, and Patrol
Scrub Support in the Memory-RAS Configuration Submenu
For Intel SGX to function properly, disable the following features in the Memory-RAS submenu
first:
•
Mirror Mode
•
ADDDC (Adaptive Double Device Data Correction) Sparing* (See the notes below.)
•
Patrol Scrub
Note 1: The feature "ADDDC Sparing" will only be activated and displayed on the BIOS
screen when x4 DRAM DIMMs, which support ADDDC(+1), are installed in the system.
Without required DRAMs present, this feature will not be activated but remains dormant,
hidden from the user's view. For ADDDC memory support, refer to the Memory RAS
Configuration User's Guide posted on our website at: https://www.supermicro.com/manuals/
other/Memory_RAS_Configuration_User_Guide.pdf.
Note 2: If ADDDC Sparing does not appear on your BIOS screen, this feature is inactive
and masked off by default, and you will not need to disable it manually.

below:
1. In the UEFI BIOS Utility, from the Advanced tab menu, select Chipset Configuration and
press <Enter>.
