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
CPU:
Pentium 4 (3.2 GHz, Fixed CPU Ratio = 16)
= 1.60
AGP/PCI/SRC Speed Setting show
= 66.68MHz/ 33.34 MHz/ 100.02 MHz
= 200 * 16
= 3200 MHz
supplied with your version of the BIOS may vary slightly. The example is for reference
only.
Given
:
Mainboard:
Intel based mainboard
DDR:
DDR333 SDRAM
CPU Speed
= CPU Host Frequency * CPU Clock Ratio
FSB
= CPU Host Frequency * 4
DDR Speed
= CPU Host Frequency * DDR:CPU Ratio
AGP/PCI/SRC Speed Setting sets to “66.68, 33.34, 100.02”
Before Overclocking:
CPU Ratio (Fixed)
= 16
CPU Host Frequency
= 200
DDR:CPU Ratio
CPU Speed
FSB
= 200 * 4
= 800 MHz
DDR Speeds
= 200 * 1.60
= 320
After Overclocking:
CPU Ratio (fixed)
= 16
CPU Host Frequency
= 220
DDR:CPU Ratio
=
1.60
AGP/PCI/SRC Speed Setting
= 66.68 MHz/ 33.34 MHz/ 100.02 MHz
CPU Speed
= 220 * 16
= 3520 MHz
FSB Speed
= 220 * 4
= 880 MHz
DDR Speeds
= 220 * 1.60
= 352
