FSB/CPU External Frequency Synchronization Front Side Bus FSB 800 FSB 533 CPU External Frequency 200 MHz 133 MHz DRAM Frequency [Auto] Allows you to set the DDR operating frequency. Configuration options: [Auto] [333MHz] [400MHz] Selecting a very high DRAM frequency may cause the system to become unstable! If this happens, revert to the default setting. The following item appears only when you install a CPU that supports the lock free feature. Only some latest CPUs support this feature.
