GPU maddness

Hi

Couple a days ago i noticed my gpu clocks are jumping all over while i am browsing the net, or using anything really, from total commander to explorer. Since i have dual monitor setup, i keep a few monitoring software's on secondary screen.
In idle the core clock is 250mhz, as soon as i move the mouse it jumps to 775mhz. Its strange since i didnt have that issue a few days ago.

On a, related issue, my card has gone nuts on YT/Twitch. While watching YT it jumps to 80% gpu usage. I checked if the hardware acc was turned on, it WASNT. I turned it on and gpu usage on YT is 10-20%, while disabled its 80%.
Same on Twitch and YT, same on Firefox and Chrome. This started a few days ago and its driving me nuts, i have less gpu usage playing games than watching YT videos in 720p.

Checked if i had any malware or such, all turned up clean. I restored a partition image 4 months old, when it all worked fine with older drivers. Same problem. Cleaned current windows with DDU and reinstalled new drivers, same problem. Both with gpu clocks and YT/Twitch gpu usage.

PC:
Mobo - Gigabyte GA-EP45C-DS3R
CPU - QuadCore Intel Xeon E5450
Ram - 2x4gb DDR2
VGA - Ati Radeon 6850 1g ram
PSU - Corsair Tx 650w

Strange thing is, that GPU clock rises, but GPU load stays low. As picture shows the clock jumping, this was browsing only, not youtube or any "heavy" content sites.

Any ideas?

Tnx

To be honest, I don't see what the problem is. My Radeon card's clocks go up and down with graphics demand as well, and it's never been a performance issue with it. My card's clock doesn't jump to the extent yours does, but it's a newer generation card. That may be the reason. I tried a couple of YouTube videos and got the same results that you are getting.

As far as my card goes, it's perfectly normal behavior.

I'd have to agree with Mellon. It seems perfectly normal for a GPU to do this. Even CPUs clocks jump up and down depending on the load. Modern CPUs and GPUs are designed to be as energy efficient as they can when not on high load.

Hardware acceleration in most cases is best left enabled. Hardware acceleration generally produces more fluid animation and means that means the graphical rendering is done on dedicated hardware such as your GPU instead of putting more stress on your CPU.

Hi,
Yep just switch to a high performance power plan and boogie on :)
