See next page for a table of the CPU BUS Frequency and CPU Core:BUS Fre-
quency Multiple Settings of supported CPUs.
WARNING! Frequencies above 100MHz exceed the specifications for the on-
board chipset and are not guaranteed to be stable. The table on the following
page is for general reference purposes only. Always refer to the instructions
included with your CPU when possible.
