Correctable Error Threshold
Use this item to enter the threshold value for correctable memory errors. The default setting
is
512 .
Intel Run Sure
Select Enable to use Intel Run Sure Technology which will enhance critical data protection
and increase system uptime and resiliency. The options are Enable and
Disable .
SDDC Plus One
SDDC (Single Device Data Correction) checks and corrects single-bit or multiple-bit (4-bit
max.) memory faults that affect an entire single x4 DRAM device. SDDC Plus One, an
enhanced feature to SDDC, copies data stored in a faulty DRAM device to a spare device
when an SDDC event has occurred. After the event, the SDDC+1 ECC mode is activated
to protect against any additional memory failure caused by a ‘single-bit’ error in the same
memory rank. The options are Enable and Disable. (Note: SDDC or SDDC Plus One is
available when it is supported by the processors installed on the motherboard.)
ADDDC Sparing (Available when Intel Run Sure is set to Enable)
ADDDC
(Adaptive Double DRAM Device Correction) Sparing , which is an improved feature
of ADDDC, will allow the error correction code to correct an error caused by the failure of
two DRAM devices or by a single-bit error that is beyond a device failure in the lockstep
mode. The options are
Enable and Disable. (Note: Virtual lockstep mode will only start to
work for ADDDC after a faulty DRAM module is spared out at Bank granularity or Rank
granularity.)
Patrol Scrub
Patrol Scrubbing is a process that allows the CPU to correct correctable memory errors
detected in a memory module and send the corrections to the requestor (the original
source). When this feature 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
Enable
and Disable.
Patrol Scrub Interval (Available when Patrol Scrub is set to Enable)
Use this item to specify the number of hours (between 0 to 24) required for the system to
complete a full patrol scrubbing. Enter 0 for patrol scrubbing to be performed automatically.
The default setting is
24 .
