3. H/W SETUP Motherboard Settings 3. HARDWARE SETUP 6) CPU External Frequency Setting (DSW Switches) This option tells the clock generator what frequency to send to the CPU, SDRAM, and the chipset. 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). Settings for PCB version 1.04 (DSW 1-5): DSW 54321 ON CPU 100MHz 54321 ON 103MHz 54321 ON 105MHz 01 01 01 01 01 01 54321 54321 54321 ON ON ON A7V133 CPU 110MHz 133MHz JumperFree Mode A7V CPU External Frequency Selection Settings for PCB version 1.02 (DSW 1-4): 4321 4321 4321 4321 ON CPU 90.00 MHz PCI 30.00 MHz ON 95.00 MHz 31.67 MHz ON ON 101.00 MHz 102.00 MHz 33.67 MHz 34.00 MHz 4321 4321 4321 ON ON ON CPU 100.00 MHz 103.00 MHz 105.00 MHz PCI 33.57 MHz 34.33 MHz 35.00 MHz 4321 4321 4321 4321 ON ON ON ON CPU 107.00 MHz 109.00 MHz 110.00 MHz 111.00 MHz A7V PCI 35.67 MHz 36.33 MHz 36.67 MHz 37.00 MHz A7V CPU External Frequency Selection IMPORTANT: 4321 4321 4321 4321 ON ON ON ON CPU 113.00 MHz 115.00 MHz 117.00 MHz 133.30 MHz PCI 37.67 MHz 39.33 MHz 39.00 MHz 33.33 MHz 1. To use this feature for both PCB 1.02 and 1.04, JEN must be set to Jumper Mode: [1-2]; [See item #2 in this section, Hardware Setup]. 2. Otherwise, if JumperFree mode is enabled, use BIOS setup in place of these switches (set Operating Frequency Setting to User Define under 4.4 Advanced Menu in BIOS Setup so you can set the CPU Frequency). WARNING! Frequencies other than the recommended CPU bus frequencies are not guaranteed to be stable. Overclocking your processor is not recommended. It may result in slower speeds than expected and premature wear of the processor. ASUS A7V User's Manual 21
