i5-2500k stuck at 3.7Ghz [Solved]

post #1 of 18
Thread Starter 
Hi

I've recently bought a new PC and have a question about the behaviour of the cpu frequency of the i5-2550k (stock speed).

I know it ranges from 3.3ghz to 3.7 but mine seems to be stuck at 3.7. As soon as I log into windows, cpu-z & aida report it at 3.7 and it doesn't change at all, even when idling for long periods.

I had a quick look in the bios and it's reported there as 3.3ghz

Is this normal?

That's definitely not normal.

Are all of the settings in the UEFI still at their defaults?

It should be idling at 1.6GHz with a very low core voltage.

Can you go into the UEFI for me and press F5 to load the optimized defaults, and then come back to Windows and see what CPU-Z says then? That is, once it is finally completely idle.

So you havent touched any bios settings and your 2500k (3.3 ghz stock) is running 3.7 in the windows environment? is that right?

Did you accidently touch any settings in the ASUS software suite? like hit the oooo so temping "OVERCLOCK IT" button? if its only windows thats reporting an overclock it has to be some sort of software overclock.

Okay, I went to UEFI and pressed F5, saved, rebooted.

Cpu-z now says: 1605Mhx(x16) and core voltage is at around 0.9.

So is this normal behaviour then? I assume it will go up and down relative to cpu usage?

I'm guessing the people who built the computer for me must have changed somethign in the bios.

Anyway thanks, was an easy fix

Yeah, that is a million times better. Now it is operating perfectly and correctly.

It's a company in the UK called Aria, they let you pick the components and build it for you (I didn't want to do it myself). They offer pre-built systems with overclocks and I asked them not to overclock mine but they still must have done something

lol Aria? Really? I'm shocked that they did this.

I think they disabled C1E and Speedstep. Hell, they probably did a bunch of other dumb things too. Don't get me wrong, I love Aria now that I know I can recommend them to my friends in the UK, but damn: they apparently don't know what they're doing with Sandy Bridge.

I'm very glad that it's working properly now. I'm also glad that you have total access to the UEFI as well which means you can begin tweaking things how you see fit! I'm especially talking about the Advanced > Onboard Devices Configuration area. My board is similar, so check mine out:

http://home.comcast.net/~twocables/UEFI%20Screenshots/Advanced%20-%20Onboard%20Devices%20Configuration%20-%20Serial%20Port.png


I disabled all of these things because I know I'm not using them and I know that I never will. I also know that if I decide to start using anything that I have disabled, then all I have to do is enable whatever it is I want to use.


Also, does your mouse work in the UEFI? If not, then attach it to one of the USB 2.0 ports instead of one of the USB 3.0 ports.
