SDDC Plus One
Single Device Data Correction (SDDC) organizes data in a single bundle (x4/x8 DRAM).
If any or all the bits become corrupted, corrections occur. The x4 condition is corrected
on all cases. The x8 condition is corrected only if the system is in Lockstep Mode. The
options are Disable and Enable.
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 Scrubbing 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 you 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.
