[. . . ] BIOS SETUP 4. 4 Advanced Menu CPU Speed [Manual] When the motherboard is set to JumperFreeTM mode, this field sets the internal frequency of your CPU. Select [Manual] if you want to make changes to the next two fields. Note that selecting a frequency higher than the CPU manufacturer recommends may cause the system to hang or crash. Configuration options: [Manual] [750MHz] [1000MHz] 4. BIOS SETUP Advanced Menu 56 CPU : System Frequency Multiple, (if CPU Speed set to [Manual]) This field is for unlocked processors only and will not be available to standard AMD processors. If the processor frequency multiple is detected as being locked, you cannot access this field. For unlocked processors, this field sets the frequency multiple between the CPU's internal frequency (CPU speed) and the external frequency. Set this field in conjunction with the System/ PCI Frequency (MHz) to match the speed of the CPU. Configuration options: [5x/14x] [5. 5x] [6. 0x]. . . [12. 0x] [12. 5x] System/PCI Frequency (MHz) (if CPU Speed set to [Manual]) This feature tells the clock generator what frequency to send to the system bus and PCI bus. The bus frequency (external frequency) multiplied by the bus multiple equals the CPU speed. Configuration ranges from 100/33 to 227/57. ASUS A7V266-EX User's Manual 4. BIOS SETUP System/SDRAM Frequency Ratio [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 System/ PCI Frequency (MHz). Configuration options: [Auto] [100:100] [100:133] Vcore [1. 775V] This field determines the range of core voltage available to the Central Processing Unit. Configuration options: [1. 850] [1. 825] [1. 800] [1. 775] [1. 750] CPU Level 1 Cache, CPU Level 2 Cache [Enabled] These fields allow you to choose from the default of [Enabled] or choose [Disabled] to turn on or off the CPU Level 1 and Level 2 built-in cache. Configuration options: [Disabled] [Enabled] CPU Level 2 Cache ECC Check [Disabled] This function controls the ECC capability in the CPU level 2 cache. Configuration options: [Disabled] [Enabled] BIOS Update [Enabled] This field functions as an update loader integrated into the BIOS to supply the processor with the required data. When set to [Enabled], the BIOS loads the update on all processors during system bootup. Configuration options: [Disabled] [Enabled] PS/2 Mouse Function Control [Auto] The default setting [Auto] allows the system to detect a PS/2 mouse at startup. If a mouse is detected, the BIOS assigns IRQ12 to the PS/2 mouse. Otherwise, IRQ12 can be used for expansion cards. When you set this field to [Enabled], BIOS always reserves IRQ12, whether or not a PS/2 mouse is detected at startup. [. . . ] Flash ROM (or EEPROM) can be reprogrammed with new programs (or BIOS). SCSI (Small Computer System Interface) High speed multi-threaded I/O interface defined by the X3T9. 2 committee of the American National Standards Institute (ANSI) for connecting many peripheral devices. The standard started from 10MBytes/sec to 160MBytes/sec available today. SDRAM (Synchronous DRAM) A type of DRAM with access signals that are synchronized with the CPU clock, eliminating the delay associated with data transfers between the CPU and memory. [. . . ]
