Branch 1 Rank. The options for Memory Interleaving are 1:1, 2:1 and 4:1 .
Enhanced x8 Detection
Select Enabled to enable Enhanced x8 DRAM UC Error Detection. The options
are Disabled and Enabled .
Demand Scrub
Scrubbing is a process that allows the North Bridge to correct correctable memory
errors found on an FBD 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 ECC,
it is corrected and sent to the original source. Memory is updated as well. Select
Enabled to use Demand Scrubbing for ECC memory correction. The options are
Enabled and Disabled.
High Temperature DRAM Operation
When set to Enabled, the BIOS will refer to the SPD table to set the maximum
DRAM temperature. If disabled, the BIOS will set the maximum DRAM temperature
based on a predefi ned value. The options are Enabled and Disabled .
AMB Thermal Sensor
Select Enabled to enable the thermal sensor embedded in the Advanced Memory
Buffer on a fully buffered memory module for thermal monitoring. The options
are Disabled and Enabled.
Thermal Throttle
Select Enabled to enable closed-loop thermal throttling on a fully buffered (FBD)
memory module. In the closed-loop thermal environment, thermal throttling will be
activated when the temperature of the FBD DIMM module exceeds a predefi ned
threshold. The options are Enabled and Disabled.
Global Activation Throttle
Select Enabled to enable the function of open-loop global thermal throttling on
the fully buffered (FBD) memory modules and allow global thermal throttling to
become active when the number of activate control exceeds a predefi ned number.
The options are Enabled and Disabled .
