CPU core clock jumps up and down from 1400Mhz to 3800Mhz constantly in CPU-Z, but not in AMD Overdrive

Thread Starter 
Hello,

In CPU-Z the core clock goesEDIT: core speed up an down constantly, is there a problem I need to fix? In AMD Overdrive though it's pretty stable, but obvously one of the two programs is lying. Also, when I changed my latency on the memorysticks from CL9 1333Mhz to standard CL8 1600Mhz, it seems like the CPU has been overclocked from 3.5Ghz to 3.8Ghz? This is what core speed is, right? But in Control Panel in System Properties it says that I have 3.5Ghz.. These questions have probably been answered many times before, but I don't know what to search for. Appreciate your time and help! smile.gif

EDIT: That's wrong, I ment the core speed.

CPUZ is correct, your cpu downclocks to save power when you aren't using as much of it.

Is it recommended to turn of power saving? I'm using my computer for FPS gaming so I want it to run as stable and smoothly as possible. How do I eventually change it?

It'll run smoothly anyway, Basically when the cpu needs the power it will give it as needed. Lets say you play something that stresses the cpu 100% it will go to the 3.8ghz and will stay there until you quit the application.

But if you want to waste energy, Go into bios and disable i think its called cool and quiet.
Small wonder.

Ok, I'll just leave it as it is then smile.gif But as to my other question, it's maybe another topic, but does the cpu gets overclocked when I change my memory latency? Why doesn't it show 3.8Ghz in Windows System Properties? I also assume it says 3500Mhz in Bios.

Windows system will only show the stock clocks as it doesn't ever update. It just takes whatever chip you have and displays the stock clocks it comes with. The CPU speed does not change if you change your memory. According to AMD your cpu can go up to 4.1ghz by itself if needed.
