CPU-Z core speed changing

[yankee99]

Why does my core speed, bus speed and rated fsb when monitoring cpu-z constantly keep changing. It (core speed) ranges from 4208-2674 mhz.

Your bus speed changes too?

What are your settings and what exactly is everything changing to?

If all settings are left at stock, then when the computer is not under load, it down-clocks itself to save on energy and reduce heat. It also employs a turbo mode when there's enough thermal headroom under load on certain cores, which boosts clock speed.

If your settings are custom, then you may be having a problem, in which case we would need more information.

I've seen my bus speed change, usually within +/- .1MHz. My guess is that's what he's talking about.

yankee, if you have not done so, go into bios and disable Cool N Quiet, C1E, Turbo, C6 and APM in bios (Note: You may not have the last two in that 880G chipset board). Then go into Windlows Control Panel Power Options and configure it to High Performance. See if that has any affect on the fluctuations you describe.

Wow lots of help. I took some screen shots of the bios. Maybe i clicked the wrong box...

Trents I think that helped. I disabled C1E and cool and quiet. I did not see Turbo, C6 and APM.

Core speed is stable between 3794.23-3795.44mhz
bus 230.0-230.2
rated fsb 2529.8-2531.2

6 core Temp seems stable between 56-59c running prime for the last 10 minutes

Here are the screen shots now
