Chapter 4: BIOS
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 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 op-
tions are Enabled and Disabled.
Force ITK Confi guration Clocking
Select Enabled to confi gure FBD clock settings to support ITK testing. The options
are Disabled and Enabled.
Reserved Branch for ITK Test
This feature allows the user to specify the memory branch number to be reserved
for ITK testing. The default setting is Branch 1.
Snoop Filter
Select Enabled to eliminate snoop traffi c to the graphics port to greatly improve
system performance when running graphics intensive applications. The options are
Enabled and Disabled.
