There are a few reasons your graphics card may not be downclocking properly. Many programs you may not expect will take advantage of your video card, putting it under load when you may not expect it.

First off, close your internet browser, as most browsers use hardware acceleration, which will put a load on your graphics card. If you have any game launchers, close them as well.

Make sure that you do not have KBoost enabled in PrecisionX.

Uninstall PrecisionX from Add/Remove Programs in the Windows Control Panel. Next perform a clean install of the Nvidia drivers by running the driver installer package and chosing the Custom option instead of Express, and checking the box that says "Perform a clean install". Reinstall PrecisionX, and see if the graphics card is downclocking properly.

If the card still does not downclock run MSCONFIG (Win 7 - Start>Run>type msconfig or Win 8 - search>type msconfig), go to the Boot tab, and chose the Diagnostic Startup option. Apply and restart your computer. This will boot Windows with only the basic services and drivers. This should eliminate any other programs that may be using the graphics card.

If the graphics card is still showing as having a load on it, you may have malware, a bitcoin miner, or other malicious software running in the background. It would be recommended to scan your system for viruses and malware and remove anything found. In extreme cases a reinstallation of Windows may be required.
