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: | Intel based mainboard |
CPU: | Pentium 4 (1.73 GHz, Fixed CPU Ratio = 13) |
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) | = 13 |
|
CPU Host Frequency | = 133 |
|
DDR:CPU Ratio | = 2.5 |
|
AGP/PCI/SRC Speed Setting show | = 66.68 MHz/ 33.34 MHz/ 100.02 MHz | |
CPU Speed | = 133 * 13 | = 1729 MHz |
FSB | = 133 * 4 | = 532 MHz |
DDR Speeds | = 133 * 2.5 | = 333 (DDR333) |
After Overclocking:
CPU Ratio (fixed) | = 13 |
|
|
|
CPU Host Frequency | = 150 |
|
|
|
DDR:CPU Ratio | = 2.66 |
|
| |
AGP/PCI/SRC Speed Setting | = 66.68 MHz/ 33.34 MHz/ 100.02 MHz | |||
CPU Speed | = 150 * | 13 | = 1950 MHz | |
FSB | = 150 | * | 4 | = 600 MHz |
DDR Speeds | = 150 | * | 2.66 | = 400 (DDR400) |
