Memory Branch Mode
This option determines how the two memory branches operate. System address
space can either be interleaved between the two branches or Sequential from one

Demand Scrubbing
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.
