Change Nvidia PowerMizer Behavior

PowerMizer is an Nvidia technology included in most Nvidia graphic cards, which allows the video card to adjust its speed to reduce power consumption and heat when not in use. However, this technology reduces the video card performance to a level which might affect some users experience with their system.

Nv GPU Tweak Tool allows you to enable or disable Nvidia's PowerMizer technology based on the system power status to promote performance when needed.

More Features

Allow GPU clock to change based on its temperature

To ensure that the video card does not overheat and shut-down while you are using your computer because you are overclocking at extreme levels, or if your GPU throttles, you can set this option to disable GPU down clock. If you are using this option, it is recommended that you monitor your system temperature very carefully, as you can damage your graphic card or system permanently.

Allow GPU core clock to slowdown

When a request to slow down the GPU is performed by the graphic card drivers, the GPU core clock can decide to slow down or not.

Allow GPU memory clock to slowdown

When disabled, whenever a request to slow down the GPU is performed by the graphic card drivers, the GPU memory clock won't be affected.

Allow brightness control

Enable or disable the graphic card to control the screen brightness of the LCD screen. This is for supported displays such as displays used in laptops.

Allow AGP sideband addressing

Data transfer system that allows the video card to send and receive information simultaneously, by using an additional bus for addresses and commands to the GPU. Once enabled it increases the performance of the video card. However, it may decrease system stability.
