Windows shows different CPU frequency than CPU-Z/BIOS

  1. Well, the title sums it up really...

    I OC'ed my AMD Phenom II X3 720 BE to it's 16x multiplier, at a comfy 3.2 GHz, just to test things and familiarize myself with it's voltages. After I set the thing to 16x and rebooted, I checked windows to see if it actually showed 3200 MHz, but it didn't. I then ran CPU-Z and Core Temp, both of which showed exactly 3200 MHz and a 16x multiplier.

    My question: Is this just a bug in windows and is my CPU actually 3,2 GHz, or is there something else going on?

    The fact that CPU-Z shows higher, changing, voltages (BIOS Core Voltage is set to 'Auto') means to me that windows is doing it wrong. But I might be completely mistaking.

    Also, on a sidenote, I wondered if the popular 'Can You Run It' webservice shows realtime CPU clock speed, or just the stock value. Because it's showing the stock value for me, but I thought it might just be getting that from where windows is getting it (the wrong location I hope that is).

    Any assistance on the matter would be greatly appreciated.

    CPU-Z is more accurate then windows with these things, i would say if both it and the bios says you have then windows isn't reading it properly

    Dont worry it is normal your cpu is running at 3200 mhz

    "can you run it" does not show your overclocked speed nor does widows experience. CPU-Z is more accurate.
