Your memory frequency is dependent on your CPU front side bus frequency. It is calculated by:
Memory frequency. = DRAM multiplier (set in the CMOS setup) * CPU front side bus frequency * 2
Note:
•If you plan to use the memory at the default speed, set the FJ1 to
•When using a 400MHz CPU, you need to set the FJ1 to
•When using a 533MHz CPU, you can set FJ1 to
Example:
1.A system using a 400MHz CPU and a PC2100 memory module with FJ1 set as
400MHz /4= 100MHz * 1.33 = 133MHz *2 (since it is a DDR module) = 266MHz
2.A system using a 533MHz CPU and a PC2700 memory module with FJ1 set as open. The multiplier in the “DRAM:CPU Ratio” option in the bios is set to 1.25, your current memory frequency will be
533MHz /4=133 MHz* 1.25 = 166MHz * 2 (since it is a DDR module) = 333MHz
Step 3. Connect cables, case wires, and power supply Install expansion cards
