Memory Frequency [Auto] This field determines whether the memory clock frequency is set to be in synchronous or asynchronous mode with respect to the system frequency. The options that appear in the popup menu vary according to the CPU Frequency (MHz). Configuration options: [Auto] [200MHz] [267MHz] AGP/PCI Frequency Setting [Auto] When set to [Auto], this field allows automatic selection of AGP/PCI frequency to enhance system performance and overclocking capability. The setting [Manual] allows you to manually select the AGP/PCI frequency. If the system becomes unstable, return to the default setting [Auto]. When this item is set to [Manual], the AGP/PCI Frequency (MHz) item appears. Configuration options: [Auto] [Manual] AGP/PCI Frequency (MHz) [66.66/33.33] This item appears only when the AGP/PCI Frequency Setting is set to [Manual]. This field allows you to select a higher AGP/PCI frequency for better system performance. Selecting a very high AGP/PCI frequency may cause the system to be unstable! CPU VCore Setting [Auto] The [Manual] setting allows you to manually select the core voltage supplied to the CPU (see next item). However, it is recommended that you keep the default setting [Auto] to allow the system to automatically determine the appropriate CPU core voltage. CPU VCore [1.500V] When the CPU VCore Setting parameter above is set to [Manual], the CPU VCore item allows you to select a specific CPU core voltage. This field is not accessible when the CPU VCore Setting is set to [Auto]. Refer to the CPU documentation before setting this field. A very high core voltage may severely damage the CPU! DDR Reference Voltage [Auto] This item controls the DDR SDRAM operating voltage. Configuration options: [2.90V] [2.70V] [2.60V][2.50V] [Auto] 2-16 Chapter 2: BIOS information
