Hi friends,

I have noticed some problems with my GPU ATI-card. It uses the CPU with a heavy load and that is really strange. Please look at Task 2042275 at my user. Any help to understand is appreciated. I have used GPU-Z to follow actions and I can see that the GPU clock works at 110MHz instead of approx 600MHz. Maybe my ATI card is a bit tired.

The only way to reset a gpu card, in Windows, is to restart the pc. After you do that it should be back up to full speed. Lots of things can make a card slow down from heat(ie self preservation) to the card being overwhelmed and just not being able what is thrown its way to a bad, or failing, card. It could even be the components are at the ragged edge and you need a bigger power supply etc. Do the Windows restart and then monitor it and see how it goes.

Mikey,

I have performed a number of restarts, so I have tried that trick. It goes OK for a while and then it happens again. The CPU % is slowly increasing. After a restart it goes the other way, slowly decreasing the CPU usage. It might be that the ATI card has reached Witts End. I have a discussion with Zy about upgrade the GPU card, but no decision yet.

I've seen high CPU load when the client needs to load and unload work from the card all the time. This can happen for various reasons but I've seen was VRM overheating that caused the card to switch to low-power mode and back to full speed after temps get better. This was with a 5970 and GPU-Z was showing VRM phases 2-3 temperatures around 150 at the time..

Did GPU-Z show that the GPU load was zero at the time? Do you mean the clock was constantly 110Mhz and not switching back and forth? How about various temperature readings?

I have now changed to a HD6850 and the problem is gone. Yes, the GPU-Z showed 110Mhz and did not change. I did put the GPU to snooze and back on again then the CPU started to decrease the used %. The average time consumption was quite high. The GPU did not went to active state whitout intervention. The ATI card was not bad, but not really in the top class. I am satisfied with my new card.

Thanks for your attention in this matter.
