DMA settings, or Direct Memory Access settings, control how the computer’s memory is accessed by hardware devices. Checking DMA settings can help improve the performance of your computer by ensuring that devices are using the most efficient DMA channels.
There are a few different ways to check DMA settings. One way is to use the Device Manager. To do this, open the Device Manager and expand the “System devices” category. Then, right-click on the “DMA controller” device and select “Properties”. The “DMA Settings” tab will show you the current DMA settings for the device.
