Asus JUMPERFREE A7V-M - Manual (Page 20)

20 ASUS A7V-M User’s Manual
3. HARDWARE SETUP
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 a slower speed and premature wearing of the processor.
2) CPU External Frequency Setting (SW1 Switches 1–4)
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).
IMPORTANT:
1. To use this feature, JEN [see 1) JumperFree™ Mode (JEN) in 3. HARD-
WARE SETUP] must be set to Jumper mode or [1-2].
2. In JumperFree mode, SW1 Switches 1,2 and 4 must be set to ON and SW1
Switch 3 to OFF (see 1) Jumper Setting earlier in this section).
3. When JumperFree mode is enabled, use BIOS setup in place of these switches
(set Operating Frequency Setting to User Define under 4.4 Advanced Menu
in BIOS Setup so you can set the CPU Frequency).
