Demand Scrub
Scrubbing is a process that allows the North Bridge 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 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 prede
fi 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 prede
fi 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 prede
fi ned number. The op-

Disabled
.
