1)AGP Bus Frequency Setting (DSW-Switch 6)

This option sets the frequency ratio between the AGP bus frequency and the DRAM (CPU bus) frequency. The default sets the AGP bus frequency to be 2/3 of the DRAM frequency. When the CPU/DRAM frequency is set to 66MHz, set this switch to [ON]. See the processor table on the next page.
