the DRAM scrub rate so all of memory is scrubbed in 8 hours.
Basic / Super / Disabled / Good / Max / User
DRAM ECC Enable
DRAM ECC allows hardware to report and correct memory errors automatically
maintaining system integrity.
Enabled / Disabled
DRAM SCRUB REDIRECT
DRAM SCRUB REDIRECT allows the system to correct DRAM ECC errors
immediately when they occur, even if background scrubbing is on.
Enabled / Disabled
DRAM BG Scrub
DRAM scrubbing corrects memory errors so later reads are correct. Doing this while
memory is not being used improves performance.
Note: When AMD’s node interleave feature is enabled, BIOS will force DRAM scrub
off.
