Description
DRAM Frequency
Auto
400 Mhz
533 Mhz
667 Mhz
Select DRAM frequency. Auto means the DRAM frequency is
selected based on SPD EEPROM information.
Note: If the selected DRAM frequency is higher than the DRAM
frequency supported by the respective memory module (derived
from SPD EEPROM information), the frequency will automatically
Memory Hole
Disabled
15MB-16MB
Enable or disable the memory hole between 15MB and 16MB. If
enabled, accesses to this range are forwarded to the LPC / PCI
bus.
DIMM Thermal Control
Disabled
40, 50, 60, 70, 80, 85,
90°C
Select DRAM module environment temperature at which to start
memory bandwidth limitation. This should help to control DIMM
temperature.
DT in SPD
Disabled
Enabled
Enable or disable support for the delta temperature (DT) in SPD
EEPROM thermal management algorithm as specified by
JEDEC.
TS on DIMM
Disabled
Enabled
Enable or disable support for the thermal sensor (TS) on DIMM
thermal management functionality as specified by JEDEC.
High Precision Event
Timer
Disabled
Enabled
Enable or disable the ICH7M high precision event timer (HPET).
This timer can be used for precise multimedia or real time
application timing. Special software support is required.
HPET Memory Address
FED00000h
FED01000h
FED02000h
FED03000h
Set the high precision event timer memory base address.
IOAPIC
Disabled
Enabled
Enable / Disable ICH7M IOAPIC function.
APIC ACPI SCI IRQ
Disabled
Enabled
If set to Disabled IRQ9 is used for the SCI.
If set to Enabled IRQ20 is used for the SCI.
C4 On C3
Disabled
Enabled
If enabled the CPU is put to C4 state, when the ACPI OS initiates
a transition to C3, for additional power saving at “Desktop Idle
Mode”.
Active State Power
Management
Disabled
Enabled
Enable or disable PCI Express L0s and L1 link power states.
PCIE Port 0

Disabled
Enable or disable PCI Express port.
PCIE High Priority Port
Disabled
Port 0
Port 1
Port 2
Port 3
Enable PCI Express high priority port for isochronous data
transfers.
Reserve PCIE Hotplug
Resources
No
Yes
Reserve I/O and memory resources for empty PCI Express slots.
Setting a PCI Express port to Enabled and reserving resources is
required for ExpressCard hotplug support on the respective port.
