PX875P PRO/ PX875P
Frequency/Voltage Control
CPU Host Frequency (MHz)
This item displays the CPU Host frequency . You can set it from XXX to 550 (or 255). The default depends on your CPU frequency. The default for this field depends on the CPU installed.
CPU Clock Ratio 8X
When you enable this field, the CPU clock ratio is fixed at “8X” and overrides the entry for the “CPU Clock Ratio” field (see “CPU Clock Ratio” field). The CPU clock ratio is used, in part, to determine the CPU clock speed (CPU clock speed = CPU clock ratio * CPU Host Frequency). It has been shown that a higher “CPU Host Frequency” and a lower “CPU Clock Ratio” is more desirable when calculating a desired CPU clock speed. This field allows you to set the CPU clock ratio to a lower than usual value (8X), allowing you to use higher “CPU Host Frequency” values.
When you disable this field, the CPU clock ratio will be determined by the “CPU Clock Ratio” field. This item will only appear when the CPU clock ratio is not locked by the CPU manufacturer.
Options: Enabled, Disabled (default)
CPU Clock Ratio
This field will only display if the CPU has not been set to a locked state by the CPU manufactory. If your CPU is locked, you will not be able to adjust the “CPU Clock Ratio”. The default depends on your CPU.
CPU Speed Detected
This item display the currect CPU speed.
CPU Speed Setting
This item display the CPU speed that you setting for. If you don’t change the “CPU Host Frequency” or the “CPU Clock Ratio” and the item will display the current CPU speed.
DDR:CPU Ratio
This item allows you to adjust your “DRAM:CPU Clock Ratio” and overclock the DDR speeds of the system. The options that are available for this item will depend on the factory default setting for the “CPU Host Frequency” BIOS field according to the table below.
