BIOS Setup [Disabled] [Private] [Sergeant] [Captain] [Colonel] [General] [Commander] Disable Dynamic Overclocking function. 1st level of overclocking, increasing the CPU frequency by 1%. 2nd level of overclocking, increasing the CPU frequency by 3%. 3rd level of overclocking, also the default value of "Load High Performance Defaults", increasing the CPU frequency by 5%. 4th level of overclocking, increasing the CPU frequency by 7%. 5th level of overclocking, increasing the CPU frequency by 10%. 6th level of overclocking, increasing the CPU frequency by 15%. MSI Reminds You... 1. Even though the Dynamic Overclocking Technology is more stable than manual overclocking, basically, it is still risky. We suggest user to make sure that your CPU can afford to overclocking regularly first. If you find the PC appears to be unstable or reboot incidentally, it's better to disable the Dynamic Overclocking or to lower the level of overclocking options. By the way, if you need to conduct overclocking manually, you also need to disable the Dynamic OverClocking first. 2. Meanwhile, there are two functions to protect user's system from crash. - There is a safe key "Ins" in BIOS. In case the overclocking fails, you can press "Ins" key while system rebooting to restore to the BIOS defaults. - If the system incidentally reboot for four times, the BIOS will also be restored to the defaults. Adjust DDR Memory Frequency When it is set to [Manual] in High Performance Mode, user can place an artificial memory clock limit on the system. Please note that memory is prevented from running faster than this frequency. Setting options: [200 MHz], [266 MHz], [333 MHz], [400 MHz], [By SPD]. CPU FSB Clock This item allows you to select the CPU Front Side Bus clock frequency (in MHz) and overclock the processor by adjusting the FSB clock to a higher frequency. Select the number between [100]~[280] for needed frequency. CPU Ratio Selection This setting controls the multiplier that is used to determine the internal clock speed of the processor relative to the external or motherboard clock speed. It is available only when the processor supports this function. CPU Voltage The settings are used to adjust the CPU clock multiplier (ratio) and CPU corevoltage (Vcore). These settings offer users a tool to overclock the system. 3-23

BIOS Setup
[Disabled]
Disable Dynamic Overclocking function.
[Private]
1st level of overclocking, increasing the CPU frequency by 1%.
[Sergeant]
2nd level of overclocking, increasing the CPU frequency by 3%.
[Captain]
3rd level of overclocking, also the default value of "Load High
Performance Defaults", increasing the CPU frequency by 5%.
[Colonel]
4th level of overclocking, increasing the CPU frequency by 7%.
[General]
5th level of overclocking, increasing the CPU frequency by 10%.
[Commander]
6th level of overclocking, increasing the CPU frequency by 15%.
Adjust DDR Memory Frequency
When it is set to [Manual] in
High Performance Mode
, user can place an artificial
memory clock limit on the system. Please note that memory is prevented from running
faster than this frequency. Setting options: [200 MHz], [266 MHz], [333 MHz], [400
MHz], [By SPD].
CPU FSB Clock
This item allows you to select the CPU Front Side Bus clock frequency (in MHz) and
overclock the processor by adjusting the FSB clock to a higher frequency. Select the
number between [100]~[280] for needed frequency.
CPU Ratio Selection
This setting controls the multiplier that is used to determine the internal clock speed of
the processor relative to the external or motherboard clock speed. It is available only
when the processor supports this function.
CPU Voltage
The settings are used to adjust the CPU clock multiplier (ratio) and CPU corevoltage
(Vcore). These settings offer users a tool to overclock the system.

-
There is a safe key "Ins" in BIOS. In case the overclocking

-
If the system incidentally reboot for four times, the BIOS will
also be restored to the defaults.
