Modifying An Asus A7V Motherboard For Duron-Overclocking

DIP Switch Settings

This table lists all possible variants of the multipliers for AMD Duron and Thunderbird. Even though all CPUs possess a fixed multiplier it can be changed with the modified Asus A7V.

Both the DIP switches "5" and "6" must be set to "on" in all adjustments because they are responsible for unblocking the multiplier lock. In our test we used a locked AMD Duron 700 and increased the clock frequency step by step. The Front Side Bus remained unchanged at 100 MHz. The AMD Duron can be operated with the multiplier setting 9 without any problems resulting in a clock frequency of 900 MHz.
