3. HARDWARE SETUP
6) CPU External Frequency Setting (DSW Switches)
This option tells the clock generator what frequency to send to the CPU, SDRAM,
and the chipset. This allows the selection of the CPU's External frequency. The
CPU External Frequency multiplied by the Frequency Multiple equals the CPU's
Internal frequency (the advertised CPU speed).
Settings for PCB version 1.04 (DSW 1-5):
A7V133
A7V CPU External Frequency Selection
Settings for PCB version 1.02 (DSW 1-4):
A7V
A7V CPU External
Frequency Selection
IMPORTANT:
1. To use this feature for both PCB 1.02 and 1.04, JEN must be set to Jumper
Mode: [1-2]; [See item #2 in this section, Hardware Setup].
2. Otherwise, if JumperFree mode is enabled, use BIOS setup in place of these
switches (set Operating Frequency Setting to User Define under 4.4 Ad-
vanced Menu in BIOS Setup so you can set the CPU Frequency).
WARNING!
Frequencies other than the recommended CPU bus frequencies are
not guaranteed to be stable. Overclocking your processor is not recommended. It
may result in slower speeds than expected and premature wear of the processor.
