manufacturer recommends may cause the system to hang or crash.
CPU Frequency Multiple [8.0x]
This field automatically sets the frequency multiple between the CPU's
internal frequency (CPU speed) and the external frequency. Increasing
the multiple increases the CPU internal frequency. Reboot the computer
for changes to take effect. Configuration options: [8x] [10x] [11x]...[24x]

lect [3x], and with PC800 RDRAM, select [4x]. If overclocking the CPU,
select [3x] to maintain stability. Configuration options: [Auto] [3x] [4x]
