R III. INSTALLATION Jumpers III. INSTALLATION 3. CPU Bus Frequency (FS0, FS1, FS2) This option tells the clock generator what frequency to send to the CPU, DRAM, and 440BX AGPset. 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 fre- quency (the advertised CPU speed). 4. CPU Core:BUS Frequency Multiple (BF0, BF1, BF2, BF3) This option sets the frequency ratio between the Internal frequency of the CPU an

III. INSTALLATION 2. System Memory (DIMM) This motherboard uses only Dual Inline Memory Modules (DIMMs). Three sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Access Memory (SDRAM) of either 8, 16, 32, 64, 128 or 256MB to form a memory size between 8MB to 768MB. One side (with memory chips) of the DIMM takes up one row on the motherboard. To utilize the chipset’s Error Checking and Correction (ECC) feature, you must use a DIMM module with 9 chips per side (
