Memory Mode
Use this feature to configure memory mode when memory is initialized. When
Independent is selected, all DIMMs are available to the operating system. The
default setting is Independent.
ArxCis
Select Enabled to use DDR3 ArxCis memory modules which combine super-
capacitor DRAM and flash memory to provide a solution to save critical data
during power failure events. The options are Enabled and Disabled.
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 by the manufacturer. The options are Auto, Force DDR3-
800, Force DDR3-1066, Force DDR3-1333, Force DDR3-1600 and Force SPD.
Channel Interleaving
This feature selects from the different channel interleaving methods. The options
are Auto, 1 Way, 2 Way, 3, Way, 4 Way and 8 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
