BIOS setting
Function
Configuration options
Effect
Auto
BIOS sets the frequency automatically.
DRAM frequency
Option for setting the RAM frequency
400, 533, 667 MHz
The desired clock frequency is set manually.
Auto
Reads the DRAM refresh rate from the SPD da-
ta of the DRAM module
7.8 μs
The DRAM refresh rate is set manually.
DRAM refresh rate
Option for configuring the DRAM refresh rate
3.9 μs
The DRAM refresh rate is set manually.
Disabled
Disables this function
Memory hole
Option for ISA cards with a frame buffer. This
does not apply to the PPC800.
15MB-16MB
Disabled
Surface temperature not limited
DIMM thermal control
Option for setting the maximum surface temper-
ature of the DIMM module. The module is cooled
by limiting the memory bandwidth if the defined
surface temperature is reached.
40°C, 50°C, 60°C,
70°C, 80°C, 85°C, 90°C
Temperature limit value for the limitation
Enabled
Enables this function
DT in SPD
Option to determine whether the GMCH (graphics
and memory controller hub) supports DT (delta
temperature) in the SPD (serial presence detect)
management algorithm of the DIMM module
Disabled
Disables this function
Enabled
Enables this function
TS on DIMM
Option to determine whether the GMCH (graph-
ics and memory controller hub) supports the TS
(thermal sensor) in the thermal management al-
gorithm of the DIMM module
Disabled
Disables this function
Enabled
Enables this function. This function is recom-
mended for multimedia applications.
High precision event timer The HPET is a timer inside the PC. It is able to
trigger an interrupt with a high degree of accu-
racy, which allows other programs to better syn-
chronize a variety of applications.
Disabled
Disables this function
Enabled
The IRQ resources available to the system are
expanded when APIC mode is enabled.
IOAPIC
This option is used to enable or disable the APIC
(Advanced Programmable Interrupt Controller).
Information:
The IRQ resources available to the sys-
tem are expanded when APIC mode is
enabled.
Disabled
Disables this function
Enabled
Uses IRQ20 for SCI
APIC ACPI SCI IRQ
This option is used to modify the SCI IRQ when
in APIC (Advanced Programmable Interrupt Con-
troller) mode.
Disabled
Disables this function
Enabled
Brings the processor to C4 if the operating sys-
tem is initiated in a C3 state
C4 on C3
Fine-tunes the power saving function on an ACPI
operating system
Disabled
Disables this function
