ADDDC Sparing
Adaptive Double Device Data Correction (ADDDC) Sparing detects when the prede-
termined threshold for correctable errors is reached, copying the contents of the failing
DIMM to spare memory. The failing DIMM or memory rank will then be disabled. The
options are Disable and Enable.
Patrol Scrub
Patrol Scrub is a process that allows the CPU to correct correctable memory errors
detected on a memory module and send the correction to the requestor (the original
source). When this item is set to Enable, the IO hub will read and write back one cache
line every 16K cycles if there is no delay caused by internal processing. By using this
method, roughly 64 GB of memory behind the IO hub will be scrubbed every day. The
options are Disable and Enable.
Patrol Scrub Interval
This feature allows the user to decide how many hours the system should wait before
the next complete patrol scrub is performed. Use the keyboard to enter a value from
0-24. The default setting is 24.
Patrol Scrub Address Mode
Use this feature to select the Patrol Scrub Address mode. The options are Reverse
Address and System Physical Address.
