My first overclock question.

Hi. I did my first overclock today on my 5200 intel, with AC pro 7 and Gigabyte GA-EP35 mobo and 2GB 800 Ram. Before I did my first overclock I read about 10 times core 2 duo overclock guide here at Tom's. Anyways I overclock from 2.5 to 3.163, by doing the multiplier 9.5x 333. And so my computer running stable and doing prime95 test at the moment. My question how come on my system information on windows it reads my cpu at 4.163? and on CPU-Z it reads at 3.163?
Thank you.

More about overclock question
  1. The most accurate is a clock that read from CPU-Z is 333 x 9 = 3163, could have occurred as a result overclok then the system will be chaotic. like say also never overclock software OCCt and CPUID read my vCore 3.73v ... wow very high when I run the standard is not overclocked. if not just ignore other problems occur if the high voltage and temperature, it will be a problem
  2. What is happening is that Windows System Information is reading the speed as 333 MHz * 12.5 (the internal multiplier of the E5200). Why it is doing that, I don't know. Some E5200's will run that fast although mine doesn't. Mine is good for 3.87 GHz.

    In addition to the generic Core2 Overclocking Guide:
    http://www.tomshardware.com/forum/259899-29-core-overclocking-guide

    take a look at Shadow's Gigabyte motherboard OC guide:
    http://www.tomshardware.co.uk/forum/page-245679_11_0.html
    It's for an EP35-DS3L.
  3. Thanks for the replies guys.I will look into that Gibabyte oc guide, because last night I tried to overclock it to 3.5 and it didn't work.
    Thank you.
  4. Well I looked at the Gigabyte guide and I overclock again following this guide, everything seems to be okay, but my windows system information still sees it higher than what I overclock it. I have it at FSB 300x10.5= 3150 GHZ I ran Prime95 for 12 hours with no errors, but windows reads it at 3750 GHZ. Here is CPU-Z and prime report maybe you guys can see something wrong here.
    Thank you.
