Does CPU core speed fluctuate?
Does CPU core speed fluctuate?
I have the AMD FX 4-Core Black Edition FX-4350 and I notice when I use the CPU-Z software that the core clock goes from the standard 4.2Mhz and every few seconds it would drop down to 1.4Mhz.
Is that normal?
Will update soon

Yes, they fluctuate. AMD has "PowerNow", Intel has "Speedstep". Basically, they throttle down when the full CPU power isn't needed.
AMD PowerNow! AMD Technology (Cool'n'Quiet Technology)
Enhanced power management features automatically and instantaneously adjust performance states and features based on processor performance requirements, helping users get more efficient performance by dynamically activating or turning off parts of the processor.
C6 power state flushes the cache and removes voltage from individual cores to help reduce power consumption
CC6 power state puts all cores in C6 into an even lower power state for quieter operation and reduced power requirements
Separate memory controller power control
IO-based c-state interface
Works automatically without the need for drivers or BIOS enablement.
Power can be switched on or off within a single clock cycle, saving energy with minimal impact on performance
Benefit: Helps users get more efficient performance by dynamically activating or turning off parts of the processor.

Thanks for clearing that up for me.
Will update soon
