Memory Mode
When Independent is selected, all DIMMs are available to the operating system.
When Mirroring is selected, the motherboard maintains two identical copies of all
data in memory for data backup. When Lock Step is selected, the motherboard
uses two areas of memory to run the same set of operations in parallel. The
settings are
Independent
, Mirroring, Lock Step, and Sparing.
DRAM RAPL Mode
RAPL (Running Average Power Limit) provides mechanisms to enforce power
consumption limits on supported processors. The options are DRAM RAPL
MODE0 ,
DRAM RAPL MODE1
, and Disabled.
DDR Speed
Use this feature to force a DDR3 memory module to run at a frequency other
than what is specified in the specification. The options are
Auto
, Force DDR3-
800, Force DDR3-1066, Force DDR3-1333, Force DDR3-1600 and Force SPD.
Channel Interleaving
Use this feature to set the DIMM channel interleaving mood. The options are
Auto
, 1 Way, 2 Way, 3, Way, and 4 Way.
Rank Interleaving
This feature allows the user to select a rank memory interleaving method. The
options are
Auto
, 1 Way, 2 Way, 4, Way, and 8 Way.
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 Enabled, 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
Enabled
and Disabled.
Demand Scrub
Demand Scrubbing is a process that allows the CPU to correct correctable
memory errors found on a 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 error, the error is corrected and sent to the requestor (the original
source). Memory is updated as well. Select Enabled to use Demand Scrubbing
for ECC memory correction. The options are
Enabled
and Disabled.
