CPU clock spped slower than it should be

[Wrick]

I have a AMD X2 4200+ 2.2Ghz CPU. I recently looked at my DxDiag report and it said that my CPU was ~1.0Ghz. Then I checked system properties and it said that it was 450Mhz! I restarted my PC. I checked another DxDiag report and it said ~2.2Ghz like it should. System properties said 991Mhz. I would close system properties and check it again and it would say 1.79Ghz. Close it and check it again and 991Mhz! All of this time it says that I have a AMD X2 4200+, but the spped is wrong.

What is going on. I have not noticed any system slow downs, but I havenot been gaming lately either.

 

[Wrick]

Really? Man if that is all it is I am going to be so happy.

Can anyone confirm or second that opinion?

 

[Pain]

You can, by going into the bios and disabling it. :?:

 

[dvdpiddy]

I second that opinion!

 

[Giraffe]

y disable it 4?
it doesnt slow your comp down when playing a game or anything else strenuous
it just saves power and makes cpu run cool and gives u speed when u need it

just leave it as it is

It's probably AMD's Cool n' Quiet. Go into the BIOS and disable it.

By the way of cool'n'quiet; can you solve my inverse problem? I have enabled it in the bios and installed the drivers but it doesn't work, the frequency remains fixed, what to do?

 

[Giraffe]

you must set the power scheme to something other than home/office desk

yes dont disable it.

To confirm it is working, download CPU-Z and leave it open while you use the pc. You should see the processor's actual speed and watch it vary along with the CPU voltate core (V-core) adjust up and down according to the speed of the processor.

To enable it (or fix if not working to fix it) make sure you have the newest amd drivers (patch released last month) and make sure it is on in the BIOS AND turn it on in Windows XP. To do so go to power management and set it to "Minimal power management" and that should do it.

yes,cool n quiet seems to be the culprit for you.just disable it and your machine should read everything correctly.and to answer the person at the bottom,disabling cool n quiet will enable you to overclock like crazy.my understanding is that with cool n quiet enabled while overclocked,you will find major instability in your system when you are not using it for anything.if someone could confirm or deny this for me i would appreciate it.anyways disable it and you shoould be fine.goodluck.

I have it turned on here. It scans 30 times a second if you need more power, your cpu immediatly powers back up to 2,2ghz.

And with C&C enabled your cpu runs cooler on a lower voltage. To me that looks like a plus.

 

[Pain]

I think the point of disabling it was to TEST if that was the reason for the variaiton. If there is a question what is causing it, turn off CC, see if everything reports correctly, then reenable it. Simple. No fuss no muss.

 

[Giraffe]

i believe you cant o/c with cool'n'quiet enabled coz it just goes back to default speeds automatically

EDIT
changing fsb speed should work
if u change the vcore it will change automatically

 

[FeareX]

You can also run a game windowed and show cpu-z on the background, it the cpu frequenty goes back up to 2,2ghz. Then you have the answer to. (playing a HD-movie in WMP maybe enough)

 

[Giraffe]

there are some free utilities u can get from the amd website such as AMD power moniter which is a little tool that can run in system tray and show u the power savings.
it also shows voltage/speed.
very useful

 

[FeareX]

Probably does the same as cpu-z. But they both work fine. (im gonna try it now to test )

Just that?!

You can OC with C&C enabled, depending on what you do. I have an opteron 170 (2.0 x 2x1mb L2) and its running at about 2.6ghz with C&C enabled. When less processing power is used or needed it downclocks 50% (drops to 5x multiplier) so in my case that is about 1.3ghz. The 1ghz mark is what they go down to (5x multi is lowest for them) but top speed depends on your proc, in your case 11x multi for 2.2ghz.

if you adjust your Vcore up or down manually you need to turn off cool and quiet, if you dont bump your vcore, you can safely leave it on.

On a mildly related note, download the newest AMD dual core update put out a day or two ago for proper CPU load balancing for your dual coare (amd or intel).

Don't think a movie needs all the 2.2GHz, on my P4 @ work, a DVD uses up about 10% of the CPU.

Nop is doesnt. But it DOES crank up the speed to full (at least it did it here) and have you ever played a High Defenition movie on your comp? You should try it and then hit ctrl+alt+del and look how much your cpu has to work. (here about 60%-70%) so this is enough to go to full speed again.

And a game like CS 1.6 has enough on my 1,21ghz but also it speeds up to 2,2ghz. So it does it pretty quickly.

Don't forget he's got a dual core. BTW, don't you have problems with CnQ enabled while overclocking, I've heared it around.

 

[FeareX]

i dont know about dual core, never really looked into it. But if you know something about dual core, then your probably right because i dont know anything about it

And the reason i dont have problems with it is because my mobo (check my sig) doesnt let me increase the voltage on the vcore. So i have maxed out the HTT frequency on stock voltage. It now runs 244fsb on stock voltage. 244*9=2196mhz

Never have stability problems with it so im happy with it.

The 3000+ is a beauty; I used to keep mine @ 239*9 ~ 2.15GHz (even 250*9 when I wanted the fastest renderings) but since I switched to a SATA drive I can nnot set the FSB to more than 224 (usually keep it 220) if I want the system ti detect i.

 

[FeareX]

So my OC to 2,2ghz is pretty good on stock voltage?

But how come SATA is holding you OC back?

Edit: there are 2 models of the 3000+ right? One on 1,4V and one on 1,35V (dont know exactly), i have the 1,4V model.

The guya around told me SATA is frequency unlocked so it had problems when OCing. You've got to have a mombo that locks it or an external (PCI) controller.

 

[FeareX]

Don't know what you mean exactly. But i dont have a SATA drive, just a IDE one. Because i had to choose a year ago, an IDE 160gb or an SATA 80gb. The IDE was only €20,- more.
