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 the function of closed-loop thermal throttling on the fully
buffered (FBD) memory modules. In the closed-loop thermal environment, thermal
throttling will be activated when the temperature of the FBD DIMM device 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.
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.
Crystal Beach Features
This feature cooperates with 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.
