3. H/W SETUP Motherboard Settings 3. HARDWARE SETUP 7) CPU External Frequency Setting (DSW-SW2-6) This option tells the clock generator what frequency to send to the CPU, DRAM, and the PCI bus. 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). NOTE: You may set the memory speed independently from the CPU External Frequency. Depending on your memory type, select the appropriate "SDRAM" speed along with the appropriate "CPU" speed. IMPORTANT: When JumperFree mode is enabled, use BIOS setup in place of these switches (see CPU Speed in 4.4 Advanced Menu). NOTE: For JumperFree mode, DIP switches 2-6 must be set to OFF.

CPU frequencies other than 66MHz and 100MHz are not guaranteed to be stable. Premature wearing of the processor may result when overclocking. Be sure that the DIMM you use can handle the specified SDRAM MHz or else bootup will not be possible. 22 ASUS P3W User's Manual
