Asus A7V Dipswitch & Jumper Settings

Asus A7V motherboard is a heaven for tweakers - it offers various control for your system. However, many settings that overclockers love are poorly documented at best. Here are the settings you need to get your CPU soaring high into the overclocking realm.
This setting must be set to 'Jumper' mode first to use the settings listed here. Otherwise, set to 'JumperFree' mode and set the jumpers/dipswitches to 'J/F' settings. Doing so will enable you to adjust the voltage and FSB settings in the BIOS, but multiplier setting will not be available.
1 = Short 1-2
0 = Short 2-3
* = Short 3-4
Default voltage setting for Duron is 1.5V and for Thunderbird Athlon, 1.7V. According to AMD's processor technical documentations, changing default voltage by -+0.1V is acceptable. Exceeding this guideline may have adverse effects to your CPU, although many Durons and Thunderbird Athlons have been reported to be able to run at the maximum voltage listed without much problem when proper cooling is provided.
1 = Switch ON
0 = Switch OFF
FSB stands for Front Side Bus, and for Athlon/Duron systems, data is 'double pumped', so the effective speed is twice that is listed here (e.g. 105MHz -> 210MHz effective). FSB is related to memory bus speed as well as AGP and PCI bus speed, so increasing this too much may harm your peripherals that cannot tolerate higher-than-specified speed.
Multiplier shows how much times faster the CPU runs in relation to FSB. For example, setting 6.0 multiplier with 110MHz FSB setting will yield 660MHz CPU speed. Multiplier setting manipulation is better way to overclock than FSB because it overclocks CPU only. However, most retail version of Duron/Athlon CPUs come with multiplier locked at manufacturing. Fortunately, it has been found that unlocking it is easy.
