X7DBi+ User's Manual

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.

Crystal Beach Features

Select Enabled to use the Intel I/O AT (Acceleration Technology) to accelerate

the performance of TOE devices. (Note: A TOE device is a specialized, dedicated

processor that is installed on an add-on card or a network card to handle some or all

packet processing of this add-on card. For this motherboard, the TOE device is built

inside the ESB 2 South Bridge chip.) The options are Enabled and Disabled.

Route Port 80h Cycles to

This feature allows the user to decide which bus to send debug information to. The

options are Disabled, PCI and LPC.

Clock Spectrum Feature

If Enabled, the BIOS will monitor the level of Electromagnetic Interference caused

by the components and will attempt to decrease the interference whenever needed.

The options are Enabled and Disabled.

High Precision Event Time

Select Yes to activate the High Precision Event Timer (HPET), which is capable of

producing periodic interrupts at a much higher frequency than a Real-time Clock

(RTC) can in synchronizing multimedia streams, providing smooth playback and

reducing the dependency on other timestamp calculation devices, such as an x86

RDTSC Instruction embedded in a CPU. The High Precision Event Timer is used

to replace the 8254 Programmable Interval Timer. The default setting is No.
