DRAM Scrub Redirect
This setting enables/disables ECC Scrubber to correct errors detected in
DRAM during normal CPU requests (foreground scrubbing).
DRAM BG Scrub

L2 Cache BG Scrub
The L2 ECC Scrub option controls the time allotted for the L2 memory cache
to be corrected when in an idle state.
Data Cache BG Scrub

cache to be corrected when in an idle state.
