3.5 Clock Generation
The Intel
®
945GME Express Chipset board uses a CK-410M and CK-SSCD compatible
solution. The FSB frequency is determined from decoding the processor BSEL[2:0] pin
settings.
The clock generator provides Processor, GMCH, ICH7-M, PCI, PCI Express*, SATA, and
USB reference clocks. Clocking for DDR2 is provided by the GMCH.
