Cm0s Show CPU frequency is not correct

Q: After my computer post, the system shows CPU working in 450MHz, but in the BIOS setup interface, the "CPU INTERNAL CORE SPEED" in "Bios&cpu Featuressetup" is 350MHz. I don't know what the reason is?

A: Some motherboard bi0s found that the hardware will automatically reduce the CMOS parameters to the safest setting after the system has been updated. The bi0s program, which supports CPU working state settings, automatically drops the CPU operating frequency to the lowest frequency CPU supported by the motherboard. Your system FSB to 100MHz, and 100MHz FSB CPU minimum frequency is 350MHz so the BIOS setup interface should show 350MHz (3.5xlOOMHz) is a normal phenomenon. Why does the system show that the CPU is working on the 450MHz (4.5x100mhz) Since your CPU is locked in 4.5, which is also a normal phenomenon.
