DDR Frequency Capability (DDRFC): This field controls which values may be
written to the Memory Frequency Select field [6:4] of the Clocking Configuration
registers (MCHBAR Offset C00h). Any attempt to write an unsupported value will
be ignored.
10 = MCH capable of up to DDR2 800
11 = MCH capable of up to DDR2 667
written to the Memory Frequency Select field [6:4] of the Clocking Configuration
registers (MCHBAR Offset C00h). Any attempt to write an unsupported value will
be ignored.
10 = MCH capable of up to DDR2 800
11 = MCH capable of up to DDR2 667

FSB Frequency Capability (FSBFC): This field controls which values are
allowed in the FSB Frequency Select Field [2:0] of the Clocking Configuration
Register. These values are determined by the BSEL[2:0] frequency straps. Any
unsupported strap values will render the MCH System Memory Interface
inoperable.
00 = MCH capable of "All" Memory Frequencies
01 = MCH capable of up to FSB 1333
10 = MCH capable of up to FSB 1067
11 = MCH capable of up to FSB 800
allowed in the FSB Frequency Select Field [2:0] of the Clocking Configuration
Register. These values are determined by the BSEL[2:0] frequency straps. Any
unsupported strap values will render the MCH System Memory Interface
inoperable.
