GTX 660 Ti, is not downclocking on idle and is running at 40C.

[battoot]

For a week now, my GTX 660 ti is not idling and downclocking on the desktop. I have tried many different drivers. I only have a single monitor and nothing has changed in my setup. Please help, I think this is a software issue
-Thanks in advance

40C is a cool temp. No issues there.
What are you using to read the GPU clock speed? EVGA Precision?

Check to see if anything running in the background. On newer video cards in the nvidia and amd control panel is a slider bar..if it set to performance the gpu want down clock.if you set it to energy savings the card will run slower to save power. There also in the control software energy savings check box.

Nothing is running in the background. I use Nvidia Inspector to check my temps/clock speeds. Power is set to Adaptive not Performance. The card usually downclocks to like 300mhz and idles at 28C. But a week ago it just randomly started to not downclock while on the desktop/ 2D mode. I have a single monitor so the two monitors isnt the problem. I tried many different drivers and as soon as i install the drivers the card downclocks, but the next time i restart my system it doesnt downclock anymore.
-Thanks

Try a different card, see if it still happens. If not, it would indicate the card is defective.
Or you could try for a possible registry error causing it. Run CCleaner and do the Clean and Registry both. Se if it finds any errors. You may need to run it more than once.

You can try, again, the latest 314.22 or 320.00 drivers, but this time do a very clean install (if you haven't already). Uninstall everything Nvidia related, then install the new drivers using the "Clean Install" option. Sorry, if you have already done this.

When's that new GTX 670 coming?

 

[battoot]

I have tried reinstalling the drivers and did clean install and it is still not down clocking on idle.

You need to check the power saving modes in the Nvidia Control Panel, which you said you already did. Then, I'm afraid it might be an RMA issue.

You could try running Driver Sweeper from safe mode (F8). Have it remove any remnants of Nvidia, AMD, and ATI graphic driver it finds.

If you close down your browser and all applications, is the clock still not idling?

I have tried many uninstalls and installs of various Nvidia Drivers including the new 320.18, and have used driver sweeper. I tried using NVinspector and used the Multi Display performance mode and it now downclocks on idle and overclocks when I am in game. But the GPU BOOST feature is not working as it used to. In 3d mode my card used to boost up to 1250mhz. Now it is stuck at 1019mhz. I really want to know if this is a hardware feature. This issue started to happen after I did a fresh install of Windows 7.
-Thanks in advance

Do you use any Logitech software or other gaming keyboard/mouse software? I found recently my clocks were locked, and it turned out to be Logitech's Gaming Software had hardware acceleration on, and since the LCD screen on the G13 is always open, my GPU's clocked up.

I use a razer deathadder and a Corsair K90 with Corsair software and Razer Synapse. I dont think this is the issue because I have had these software when my GPU was working properly.

Was there any updates? I didn't used to have a problem with Logitech's software either, until they made it use hardware acceleration in an update. I just turned it off, and now everything works fine. That said, there is more and more software being made that uses hardware acceleration. You might need to check it all for options to turn off. Including adobe and your browser.

I ran CCcleaner plenty of times and used Driver Fusion to do a very clean Nvidia driver install. Do you think this is a hardware related issue.

I still think you have some software that has hardware acceleration and you just don't realize it. I've had 4 different times over the past 2-3 years that has done the same thing to me. All of them were new hardware acceleration features added to software I was using. I.E., Firefox, flash and Logitech have changed their software to added acceleration, and I discovered it by my GPU clocks. The interesting thing, and also draws parallel with your situation, is the clocks were not the normal default clocks, nor the overclocked settings I had set for the cards.

I will definately try uninstalling some software to test this out, this weekend
-thanks

tthere is an option on NVidia tool for "adaptive" or "maximum performance". check adaptive.

I already set it to adaptive.

That is a picture of my GPU usage on IDLE. I dont know why it is doing these perfect spikes. I am using Multi Display Power Saver from Nvidia Inspector so the card wouldnt run at 3D mode in idle. When my screen goes black. My card jumps to 99% usage.
-Thanks in advance

I have finally figured out what the problem was. Everytime I started my PC, Grand Theft Auto San Andreas would load up even though it wasnt on msconfig. This was very weird since I uninstalled the game a while ago. It told my GPU that a game was running in the background. Now my issue has been fixed
Thanks guys!

I know it's been a while, and that this thread has been "resolved", but my solution could help someone else.

I have a GTX 660 hooked to 3 LCD monitors on Win7 ultimate 64. This setup have been performing flawlessly for over 2 years now.

Unexpectedly, 2 days ago, for reason I still can't understand, the GFX card stop downclocking to idle speed (324Mhz GPU, 162Mhz RAM), but stayed at P2 P-State (862Mhz GPU, 1500Mhz RAM) after quiting a 3D application or game. It would boost and turbo boost to max clock, no problem, but never went down all the way back to 2D idle clock.

I tried everything in the book, including system restore 10 days earlier, uninstalling a bunch of stuff and using DDU to uninstall the video driver in safe mode. Still the same issue. I was about to consider either my card had an hardware issue, on windows/the registry was borked and need a fresh install.

Then, out of desperation, I went back to the GPU driver control panel and looked at all the options and settings 1 by 1. I then remembered reading this thread sooner today where it was mentioned multiple times "I have only 1 monitor" and thought "maybe my problem has to do with my 3 LCD setup." I disabled 2 of the 3 monitors with GPU-Z opened for monitoring and immediately, the clock went down! Amazing! I then re-enabled the 2 monitors, fired up to a game and immediately after quiting the game, the clock went down to Idle speed as it should, with all 3 LCD enabled.

Problem fixed and I wound NEVER have guessed... Hope this helps someone someday!
