AMD FX-6350 3.9Ghz running at 1.4Ghz?

Hi there,

I am somewhat new to building completely custom systems. The most I have done up until this point has been disassembling and reassembling currently existing builds/upgrading.

This is my fist custom system, and this is the first stock processor I have ever actually purchased my self.

The system is up and running no problem, CPU meeting stock temps, etc etc. It's been running fine for the approximate two weeks I've had it running... until today.

When I booted up my system and logged on today, I noticed oddly slow performance. I noticed my browsers and games lagging, and then continued to notice that my CPU usage would spike heavily. I took a look at my utility program and noticed that it showed my CPU as running at 1.39Ghz . I then opened up dxdiag, and noticed that it too listed my CPU as a 6-Core 1.4 Ghz processor.

Up until this point, my CPU has been running great at the stock 3.9Ghz. Would anyone be so kind as to help a newb out? I appreciate any and all assistance :)  .

Thank you very much!

what motherboard are you using? p.s the fx line of cpus downclock themselves when theres nothing intense goin on in the pc

Run a stress test (prime95) and look at the frequency during the test. Like mentioned above it is most likely just the CPU downclocking itself...

Do you have Cool 'n' Quiet enabled in the BIOS? If so, disable it.

This is the most common cause for "problems" such as this.

My motherboard is the ASRock 970 EXTREME4 AM3+. Let's use League of Legends as an example. When running league of legends before, it would peak at about 30% CPU usage. Today, with my clock seeming to be at 1.4Ghz, launching League of Legends causes my CPU to read 60% usage approx, and the game performs noticeably worse. I find it hard to believe that League of Legends is using approximately 45% of my 6-Core, 3.9ghz CPU.

Thank you for the information about its automatic downclocking, however, as I was not aware of this.

Try running prime95 and watch the frequencies in CPU Z

(Update: I found that my Frequency Multiplier became locked at 7x. Enabled IES and I am at stock performancy now. Thanks for all of your help :)  )

Maybe go into the BIOS and make shouldthe multiplier is set to 3900mhz and the voltage to stock. This should clock you to stock clock speeds. You will also want to disable cool 'n' quiet (this is what automatically downclockes the CPU).

Yup yup, thanks xD . I was unable to find a cool 'n' quite option when running through my BIOS, but I did notice shortly prior to your post that my multiplier was locked at 7x. Luckily, I was able to set my multiplier to variable with IES in my AXTU utilities program, and everything is working great now xD . Thank you very much for your help :)  .
