Channel Interleaving
Use this feature to set the DIMM channel interleaving mood. The options are Auto ,
1-Way Interleave, 2-Way Interleave, 3-Way Interleave, and 4-Way Interleave.
Rank Interleaving
Use this feature to select a rank memory interleaving method. The options are
Auto
,
1-Way, 2-Way, 4-Way, and 8-Way.
DRAM Maintenance
Select Auto for the BIOS to automatically configure DRAM Refreshing and Patrol
settings. The options are Manual and Auto .
pTRR (Pseudo Target Row Refresh) Support
Select Enabled for Pseudo TRR support which will allow the BIOS to assign an
invalid address to a questionable memory module to prevent this memory module
from being accessed by other components. The options are
Enabled and Disabled.
Injection Probability
AMEI (Asynchroous MCA Error Injection) (AMEI) is a error-handling mechanism
that allows the BIOS to report the MCA errors to the CPU core or the CPU before
resuming normal operations. This item is used to set the threshold of the AMEI
events beyond which the BIOS will report the error events before resuming
operations. The options are 512, 1024, 1365, 1638, 1820, 1928, 2048, 2731, 3277,
3641,

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 Enable to use Demand Scrubbing for ECC memory correction. The
options are
Enable and Disable.
Device Tagging
Select Enable to support device tagging. The options are
Disable
and Enable.
Memory Power Management
Select Enabled for memory power management support. The options are Disabled
