PCI Revision 2.3 compliant
33 MHz
5 V tolerant PCI signals (except PME#)
Integrated PCI arbiter supports up to seven PCI bus masters
2.5.5 PCIe Bus
The Intel® ICH7M Southbridge chipset has four PCIe lanes. These PCIe lanes are
connected to PCIe x1 devices.
2.5.6 GbE Ethernet
The ICE-945GSE provides a Gigabit Ethernet connection through the Intel® 82541PI chip
connected to the LAN connector on the Intel® ICH7M.
2.5.7 Real Time Clock
ICE-945GSE COM Express Type 2 Module
The real time clock in integrated in the Intel® ICH7M. The RTC operates on a 3 V battery
and 32.768 KHz crystal. The RTC keeps track of the time and stores system data even
when the system is turned off.
2.5.8 SATA Controller
The integrated SATA controller on the Southbridge supports up to two SATA drives with
independent DMA operations.
SATA controller specifications are listed below.
Supports two SATA drives
Supports 1.5 Gb/s data transfer speeds
Supports Serial ATA Specification, Revision 1.0a
2.5.9 SPI Bus
The Serial Peripheral Interface is a short distance serial bus for communication with other
devices on the motherboard. The SPI interface from the board is interfaced to the items

SPI BIOS.
ICE-945GSE COM Express Type 2 Module
2.5.10 USB Controller
Up to eight high-speed, full-speed or low-speed USB devices are supported by the Intel®
ICH7M on the ICE-945GSE. High-speed USB 2.0, with data transfers of up to 480 MB/s, is
enabled with the Intel® ICH7M integrated Enhanced Host Controller Interface (EHCI)
compliant host controller. USB full-speed and low-speed signaling is supported by the
Intel® ICH7M integrated Universal Host Controller Interface (UHCI) controllers.
2.6 Environmental and Power Specifications
2.6.1 System Monitoring
The ICE-945GSE monitors the following temperatures:
CPU temperature
System temperature
On-chip temperature
The ICE-945GSE monitors the following fan speeds:
CPU (FAN1) speed
System (FAN2) speed
System (FAN3) speed
The ICE-945GSE monitors the following voltages:
Vcore
+12 V
+3.30 V
+5.00 V
VBAT
The values for the above environmental parameters are all recorded in the BIOS
Hardware Health Configuration menu.
2.6.2 Operating Temperature and Temperature Control
The maximum and minimum operating temperatures for the ICE-945GSE are listed below.
Page 17
Minimum Operating Temperature: 0ºC (32°F)
Maximum Operating Temperature: 60°C (140°F)
A cooling fan and heat sink must be installed on the CPU. Thermal paste must be
smeared on the lower side of the heat sink before it is mounted on the CPU. Heat sinks
are also mounted on the Northbridge and Southbridge chipsets to ensure the operating
temperature of these chips remain low.
