III. INST ALLATION Jumpers III. INSTALLATION 1. Jumpers 1. CPU Bus Frequency (FS0, FS1, FS2) This option tells the clock generator what frequency to send to the CPU, DRAM, and chipset. This allows the selection of the CPU's External frequency (or BUS Clock). The BUS Clock multiplied by the BUS Ratio equals the CPU's Internal frequency (the advertised CPU speed). 2. CPU Core:BUS Frequency Multiple (BF0, BF1, BF2, BF3) This option sets the frequency ratio between the Internal frequency of the CPU and the CPU's External frequency. These must be set in conjunction with the CPU Bus Frequency. 123 123 123 123 123 123 FS0 FS1 FS2 66.8MHz 75MHz 83.3MHz 100MHz 103MHz 112MHz CPU Bus Frequency BF0 BF1 BF2 BF3 BF3 BF2 BF1 BF0 BF3 BF2 BF1 BF0 BF3 BF2 BF1 BF0 BF3 BF2 BF1 BF0 BF3 BF2 BF1 BF0 BF3 BF2 BF1 BF0 XG-DLS R XG-DLS CPU Settings 1 2 3 2.0x (2/1) 2.5x (5/2) 3.0x (3/1) 3.5x (7/2) 4.0x (4/1) 4.5x (9/2) BF2 BF1 BF0 BF3 BF2 BF1 BF0 BF3 BF2 BF1 BF0 BF3 BF2 BF1 BF0 BF3 BF2 BF1 BF0 BF3 BF2 BF1 BF0 1 2 3 5.5x (11/2) 6.0x (6/1) 6.5x (13/2) 7.0x (7/1) CPU Core:Bus Frequency Multiple 7.5x (15/2) 8.0x (8/1) BF3 5.0x (5/1) WARNING!
