Hallo, at System start up , My Core I 5, 2.8Ghz , Overclocks itself, to 3.5 Ghz, Multiplier is set to 25 ????, then after a Minute , it drops to 1.2 Ghz, Multiplier drops to 9
The first part is called turbo. It is a feature of the processor to improve performance.
The second is speedstep, designed to reduce power consumption when there is little or no demand on the CPU.
Neither is a concern and both are an advantage to have.
When I enable XMP on The MSI P55-GD65 Motherboard, from 133 MHz, to 160 MHz, the CPU goes up to 4.0, MHz ?????
Don't mess with bios settings if you don't know what you are doing.
