CPU issue ( only at half of its power)

[idata]

It used to run at its full capacity but for some reason a few months ago it started dropping. At first I thought maybe some viruses have infested my PC or maybe my drivers were outdated, I even cleaned all of the dust inside the PC. Turns out that wasn't the case as you can see from the pictures below my CPU is running at 1.6GHz instead of 2.3GHz.

I know at some point I had 2.3ghz because back when Modern Warfare 2 I could run it at max settings and have a good frame rate now even if I put it at medium settings I get a very low frame rate.

My motherboard is asus P5LD2-X/1333

PS: After this post I tried reseting the bios and disabling the speedstep and C1E. But that only made the speed stay at 1.86ghz.

Hello;

As first troubleshooting I recommend to update your system BIOS

Once you update the BIOS download and the install the Intel(R) processor Identification utility, you can download this application at the following url:

http://www.intel.com/support/processors/tools/piu/ http://www.intel.com/support/processors/tools/piu/

If this application is giving you the proper processor speed this means that your processor is running as it should

If the problem continues you can try to test the processor on another desktop board just to make sure that is not a faulty unit
