OC'd 2500k not recognized by windows 7 or other programs

post #1 of 9
Thread Starter 
Hi guys, I'm new to overclocking. I just bought a 2500k with a GA-P67A-UD3 mobo, and have it overclocked to 4.0ghz. I did this simply by changing the core multiplier in the BIOS, no other voltages or clock speed options were changed. My problem is that the overclocked speed is not showing up in the windows system properties or in any other programs like CPU-Z. The only place the overclocked speed is recognized is the POST screen from the BIOS during boot.

When I run benchmark tests I AM getting appropriate overclocked scores, much higher than when I go into the BIOS and set the clock speed back to stock and then rerun the tests. I am not sure why no programs are recognizing the overclocked CPU speed though? I know that there is a BIOS feature to have the CPU remain at sub-maximal clockspeeds to save energy when it is not being stressed... so I opened up CPU-Z and then tried to strain the CPU by having itunes playing, mass effect 2 playing, and starcraft 2 playing on separate screens all at the same time in HD resolution... the CPU speed still did not show as rising above stock values even though the refresh rates dropped below 30fps, which I assume means there was enough strain to warrant running the CPU at maximal speed. What gives?

First of all Welcome to OCN..
Second 4 ghz is nothing, I can do 4.6 ghz without touching my voltage..
GO FOR MORE!!!!!
Third, nevermind what the programs are reading your cpu as, Windows, and most benchmarks show my cpu as 3.3 ghz..
Trust in CPU-z..
(Get version 1.56.3)

strange.. try disabling settings in BIOS that interferes with ocing.. like c1de etc..
and.. since you already showed two types of proof ( post screen and scores ) you're oc'd, nothing to worry about.. post screens of cpu-z and computer properties?

are you sure you have a K-series chip?

lol ummm yes of course I am sure I have a K series chip... here is a screenshot of the CPU-Z processor tab, still showing stock clock values...

Don't bother with what is under specification. Farther down where it says core speed shows it is underclocked which is most likely due to power management. Someone else would have to tell you how to disable power management as I don't know intel system that well anymore.

Yes you need to disable c1e, eist, and such in the bios under advanced bios settings.
I have same mobo as you.

With utmost respect to the OP and just to ease my curious mind.....is this how we overclock these days?

From looking at your CPU-Z, your clock speed is set to idle, meaning that when you are idle, your clock speed is reduced so there isnt any unnessesery heat production. Disable the unneccesery bios settings quoted below and your problem shouldnt last
