DRAM ECC allows
hardware to report and
correct memory errors
automatically,
maintaining system
integrity.
DRAM ECC Enable [Enabled]
Allows you to enable or disable DRAM ECC, which allows the hardware
to report and correct memory errors automatically to maintain system
integrity. Configuration options: [Disabled] [Enabled]

DRAM BG Scrub [Disabled]
Allows DRAM scrubbing to correct memory errors so later reads are correct. Doing this
while memory is not being used improves performance. Configuration options:
