3. H/W SETUP Motherboard Settings 3. HARDWARE SETUP 8) CPU External Frequency Setting (DSW) 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. NOTE: For JumperFree mode, all dip switches (DSW) must be set to OFF.

If your processor does not have a locked Frequency Multiple, you must use CPU Core:Bus Freq. Multiple in 4.4 Advanced Menu of the BIOS setup to set the Frequency Multiple. If the Frequency Multiple is locked, setting the Frequency Multiple in BIOS setup will have no effect. WARNING! CPU frequencies above 66MHz exceed the specifications for current Celeron processors and are not guaranteed to be stable. For Coppermine processors, CPU frequencies other than the recommended bus frequencies 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 CUWE User's Manual
