CPU Misreading

Here is what 3 different monitors show my CPU running at, 4 different frequencies.
What is up, does your show something similar? This is at idle BTW, just these things running.

When i do open two of my monitors, i've got a delay between half a second to one second through the multiplier/core speed...between the two monitors

Yours looks more obvious on the three monitors, does it stays stable at one moment or is it stuck?.

Non: The readings are constantly changing and never match in any two at one time.

John: I agree, it doesn't seem normal, at least yours are very close.

i series chips mess with these alot lately.
Basically only check it under load. Those numbers should match.
While idle you'll likely see readings all over the place.

NP I learned the same thing when I first got this i7 I have now.
It's all part of the new power management stuff in the i series intel chips.
