DDR2 memory DIMM frequencies of 800/667. It supports two DDR2 Sockets with
up to maximum memory of 4 GB. DDR2 Maximum memory bandwidth of 12.8 GB/
s in dual-channel symmetric mode assuming DDR2 800 MHz. High resolution graph-
ics via one PCI Express slot, intended for Graphics Interface, are fully compliant to
the PCI Express Base Specification revision 1.1.
The ICH7 Southbridge supports two PCI slots which are PCI 2.3 compliant. In
addition, one PCI Express x1 slot is supported, fully compliant to the PCI Express
