R III. INSTALLATION 6. 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 ad- vertised CPU speed). 7. 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 frequenc

III. INSTALLATION 2. System Memory (DIMM) This motherboard uses only Dual Inline Memory Modules (DIMMs). Sockets are available for 3.3Volt (power level) unbuffered Synchronous Dynamic Random Ac- cess Memory (SDRAM). 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 (standard 8 chips/side + 1 ECC chip) and make the proper settings through “Chipset Fe
