Important
Overclock±ng your PC manually ±s only recommended for advanced users.
Overclock±ng ±s not guaranteed, and ±f done ±mproperly, can vo±d your warranty or
severely damage your hardware.
If you are unfam±l±ar w±th overclock±ng, we adv±se you to use OC Gen±e for easy
overclock±ng.
Current CPU/ DRAM Frequency
These ±tems show the current clocks of CPU and Memory speed. Read-only.
Adjust CPU Rat±o
Controls the mult±pl±er that ±s used to determ±ne ±nternal clock speed of the processor.
Th±s feature can only be changed ±f the processor supports th±s funct±on.
Adjusted CPU Frequency
It shows the adjusted CPU frequency. Read-only.
Adjust CPU Rat±o ±n OS
Enable th±s ±tem to allow CPU rat±o changes ±n the OS by us±ng MSI Control Center II.
Internal PLL Overvoltage
Th±s ±tem ±s used to adjust the PLL voltage.
EIST
Enhanced Intel SpeedStep technology allows you to set the performance level of the
m±croprocessor whether the computer ±s runn±ng on battery or AC power. Th±s field only
appears w±th ±nstalled CPUs that support th±s technology.
