P150HM W 6970 jittery GPU clocks

I have a Eurocom Racer/Clevo P150HM with a HD6970 and according to GPU-Z its trying to clock up the video card whenever I surf the net. After browsing the net for a while the GPU-Z clock windows looks like a EKG heart rate machine. Every time you click a new page it trys to raise the clocks. I have several other PC and none of them act like this. Just wondering if its normal or is it a sign of a card going bad? I had trouble after installing Windows getting it to clock off idle untill I gave it a tiny overclock on the GPU-Memeory, then it worked fine. Anyways just wondering if anyone else has this issue? THanks for any help. I also am using the default 11.8 drivers provided by Eurocom.

 

104 views and no one can confirm for me if this is normal just on my machine? I am wondering if its from the Sandy bride super fast reaction times [prefetching] that is like Lucy pulling the football away from Charlie Brown every time he want to kick it?

 

Clocks shift up and down depending on the graphics requirements of the page. Mine clock up whenever there is a flash video or even if you scroll really quickly. It clocks up automatically for brief increments (like turboboost) to ensure smooth performance.

 

I've noticed that this happens a lot to me when using Firefox. Harmless, but it annoys the hell out of me when it raises the clocks up to max just to scroll a page or load a freaking picture. It usually only does it for a few seconds, then goes back to idle, unless of course I'm watching a Flash video or something, but I hate seeing my temps and clocks constantly jumping around for no good reason. And I know it's pointless because I have since completely disabled hardware acceleration in FF and everything is just as smooth. Oh and for the record Internet Explorer doesn't do this from what I've seen. It actually makes proper use of gpu acceleration and uses it when needed.

 

What browser are you using on your machine? Most modern browsers are hardware accelerated, so they'll try to use the GPU on multimedia heavy rendering (especially flash). You can turn it off in Firefox under options > advanced > general > browsing, and in Google Chrome under about:flags and disabling these three options:

GPU accelerated compositing
GPU Accelerated Canvas 2D
Web page Prerendering

Otherwise, I'd assume this is fairly normal as the browser is offloading work to the GPU and it's bumping up the clocks from a low power idle mode. Desktop machines may not go as low in power saving mode, so they may not need to constantly adjust clock rates. (just a guess on that part though)

 

You can use ATI Tray Tool to manually control the clocks. Read this thread.

 

^^^ You can use it to lower the voltage too. For idle I have mine set at .77v. Increases battery life and lowers temps.

 

Wow fantastic info people. I do use Firefox, so I will make the necesary tweaks.
