Demand Scrub
Scrubbing is a process that allows the North Bridge to correct correctable memory
errors found on an FBD memory module. When the CPU or I/O issues a demand-
read command, and the read data from memory turns out to be a correctable ECC,
it is corrected and sent to the original source. Memory is updated as well. Select
Enabled to use Demand Scrubbing for ECC memory correction. The options are
Enabled and Disabled.

errors found on FBD memory modules. Select Enabled to use Patrol Scrubbing,

written back into memory. The options are Enabled and Disabled.
