Realizing the shared memory of the graphics card in the Vista system

The memory problem with the video card under Windows Vista has been bothering me. My graphics card is NVIDIA Geforce 7300LE discrete graphics, 64MB of video memory, 319MB after system sharing. However, I feel that 319MB is not very useful. I always want to add more points, so I will look at the information today.

Independent Graphics

Here, I use the NVIDIA Geforce 7300LE discrete graphics card I used as an example. Before I installed 512MB of memory, the graphics card shared 64MB of video memory.

Later I installed two 512MB of memory, of which the graphics card shared 255MB of video memory. Then I searched the network for the same NV graphics card, when 512MB of memory, 512MB of memory, the system shared 225M. When the memory is 1G, the memory shared memory is 225MB, and when 2G memory is shared, 271M memory is shared.

Under Vista, the value of memory and graphics card shared memory is systematically determined, and users cannot make adjustments themselves.

Shared Graphics

Fortunately, users sharing a graphics card can share resources with memory and graphics cards, such as notebook users.

Specific method:

Boot into the BIOS for setup. Find "advanced chipset features", press Enter to enter, select the option to 64MB. Press the "page up" button to change the value to 128MB.

Shielding shared graphics:

As we all know, as long as the discrete graphics card is installed, the system will automatically shield the shared graphics card, but there are special cases, if a separate graphics card is installed, The shared memory is not blocked, and the discrete graphics card can't play it. What should I do?

Workaround:

1) Boot into the BIOS setup (there are items in the settings. ON BOARD*** (VGA) is set to DISABLE).
2) If you are using a discrete graphics card for integrated graphics, you can disable the integrated graphics card in the device manager
