Example:
This example shows you how to overclock the CPU Internal Clock, DDR frequency
and FSB frequency for an Intel based mainboard. Note that the options that are
supplied with your version of the BIOS may vary slightly. The example is for reference
only.
Given:
Mainboard:
CPU:
DDR:
CPU Speed
FSB
DDR Speed
AGP/PCI/SRC Speed Setting sets to "66.0, 33.0, 100"
Before Overclocking:
CPU Ratio (Fixed)
CPU Host Frequency
DDR:CPU Ratio
AGP/PCI/SRC frequencies
CPU Speed
FSB
DDR Speeds
After Overclocking:
CPU Ratio (fixed)
CPU Host Frequency
DDR:CPU Ratio
AGP/PCI/SRC Speed Setting
CPU Speed
FSB
DDR Speeds
Intel based mainboard
Pentium 4 (1.73 GHz, Fixed CPU Ratio = 13)
DDR333 SDRAM
= CPU Host Frequency * CPU Clock Ratio
= CPU Host Frequency * 4
= CPU Host Frequency * DDR:CPU Ratio
= 13
= 133
= 2.5
= 66.0 MHz/ 33.0 MHz/ 100 MHz
= 133 * 13
= 133 * 4
= 133 * 2.5
= 13
= 150
= 2.66
= 66.0 MHz/ 33.0 MHz/ 100 MHz
= 150 * 13
= 150 * 4
= 150 * 2.66

= 1729 MHz
= 532 MHz
= 333 (DDR333)
= 1950 MHz
= 600 MHz
= 400 (DDR400)
