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, which determine how memory
blocks are cached in a DRAM buffer and a memory module accesses memory
resources. Select Open to optimize memory performance. Select Close to use
memory safe mode. Select Adaptive to balance safety and performance. The
options are Close, Open and Adaptive.
Scheduler Policy
Use this feature to confi gure Scheduler_Policy settings. The scheduler is used
to translate memory read/write commands into memory sub-commands for easy
execution. Select Static Trade_Off to balance read/write priority. Select Static
Read_Priority to optimize read latency and bandwidth. Select Static Write_Pri-
ority to optimize write bandwidth to expedite command writing and command
execution. Select Adaptive to minimize latency. The options are Static Trade_Off,
Static Read_Priority, Static Write_Priority, and Adaptive.
ECC Check Time Interval
This feature is used to set the time interval between each ECC Memory checking.
If an ECC error occurs, an error message will also be sent via IPMI. The options
are 100 Msec, 1 Sec, 10 Sec, 1 Min, 5 Minutes, and 10 Minutes.
North Bridge Confi guration
This feature allows the user to confi gure North Bridge settings.
Relaxed Ordering
Select Enabled to enable PCI-Express Relaxed_Ordering support which will allow
certain transactions to be executed fi rst by passing other transactions that were
issued earlier, violating the strict PCI-E ordering rules. The options are Auto, Dis-
abled and Enabled.
Maximum Payload Size
This feature is used to set the maximum payload size for a PCI-Express device.
Please refer to your add-on card user guide for the desired setting. The options
are Auto, 128 Bytes, 256 Bytes, 512 Bytes, 1024 Bytes, 2048 Bytes, 4096 Bytes,
7-11
