Spare Enable
Select Enabled to enable spare support for all sockets, creating a spare drive
for each socket. The options are Enabled and Disabled.
Mapper Mode
Use this feature to set the memory_mapper mode. The memory_maper is used
to translate local physical addresses presented by a media device into DRAM
memory addresses (in terms of rank, bank, row and column). Select Open to
maximize open_page hits. Select Close to minimize rank confl icts and to maxi-
mize command and simultaneous read/write bandwidth to boost performance.
Select Adaptive to spread power dissipation over different DIMM modules to
avoid memory overheating. The options are Close, Open and Adaptive.
Frequency Limit
This feature forces a DDR3 memory module to run at a frequency other than
what the system has detected. The available options are Auto, 800 MHz, 978
MHz, 1067 MHz, and Auto.
Initialization Mode
Use this feature to select the memory initialization mode. The options are Serial
and Parallel.
Hemisphere Mode
This feature is used to set the memory hemisphere mode. Select Enabled to
prevent CPU's cache agent 1 from accessing cache agent 2 in an effort to
reduce memory latency and maximize performance. This setting requires that
both DIMM modules and DRAM sizes are confi gured in the same way. Select
Disabled to allow a CPU's cache agent 1 to access cache agent 2. The options
are Disabled and Enabled.
Page Policy
Use this feature to confi gure Page_Policy settings. A page is a set of memory
blocks cached in a DRAM buffer that determines sub-commands needed for a
memory module to access a particular page. Select Open to optimize memory
