Demand Scrub

Chapter 4: BIOS

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 Conﬁguration 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.
