Recently parsing through a dump file which produced this

But then this:

I am used to seeing the Max Speed value, reasonably close (one way or the other) to the Current Speed value and or the actual processor speed in this case 3400MHz.
Can anyone tell me what I am looking at here and what might account for the incredible disparity between the second set of those two values.

Most likely some power management settings that's typical with CPUs nowadays to underclock themselves for specific reasons, such as heat reaching a certain temperature or CPU usage not reaching specified thresholds.

Though 7 GHz? That's very peculiar.

Though 7 GHz? That's very peculiar.

That is more or less what I was thinking as well. 7GHz? Was wondering where that came from or what might have produced that information.
Accounting and allowing for various things like TurboBoost, Kool n' Quiet, EIST, etc., given that it is a 3.4GHz processor and a Max Speed indication of over double that, I guess my question would be, how reliable is that particular entry in the debugger, is it accurate and an indication of either current or historical Over Clocking?

What does BIOS show?

CPU-z?

Sorry John, attached now.
And it reflects, at least as best I can determine, that at the time that CPUz was ran the OP's computer was under the control of EIST and under clocked.
But that is only one particular point in time and I have suspicions that with the presence of GVTDrv64.sys 9/5/2006, I suspect some historical EasyTune OC'ing and I was just wondering if that particular piece of information in the dump file was evidence of my suspicions, that's all.

I always direct the user to remove GVTDrv64 or any other out-of-date or troublesome motherboard utilities. It's sad to say, but they're awful and buggy. I'm old fashioned too... something about creating a bridge between the OS and the BIOS and making BIOS changes in the OS bothers me.

Regards,

Maybe since it's a new Ivy Bridge CPU the data is not read properly? That CPU would have a max frequency of no more than maybe 5.5GHz even on liquid helium and 4.8GHZ or so on air or water cooling.
I agree using software in the OS to fool with overclocking is not a good idea, been there done that. :banghead:
