Q45 GMCH

Intel Graphics Media Accelerator 4500 (integrated graphics controller)

 

PCIe 2.0 x16 graphics interface (1)

 

SDRAM controller supporting unbuffered, non-ECC PC2-6400 DDR2

 

DIMMs or SODIMMs

 

800-, 1066-, or 1333-MHz FSB

 

 

82801 ICH10-DO

PCI 2.3 bus I/F

 

PCI Express x1

 

LPC bus I/F

 

SMBus I/F

 

SATA I/F

 

HD audio interface

 

RTC/CMOS

 

IRQ controller

 

Power management logic

 

USB 1.1/2.0 controllers supporting 12 ports

 

(these systems provide 8 external, 3 internal)

 

Gigabit Ethernet controller

 

 

The I/O controller hub (ICH10-DO) supports Intel vPro, which uses Active Management Technology (AMT). AMT is a hardware/firmware solution that operates on auxiliary power to allow 24/7 support of network alerting and management of the unit without regard to the power state or operating system. AMT capabilities include:

■System asset recovery (hardware and software configuration data)

■OS-independent system wellness and healing

■Software (virus) protection/management
