Memory Upgrade
If you currently have a 4MB XCLAIM VR card, you can
upgrade to 8MB by adding a 4MB SGRAM upgrade
module.
By adding additional memory you do not gain additional
2D resolutions or color depths since a 4MB XCLAIM VR
card provides 32-bit colors in all supported resolutions.
However, adding an additional 4MB of RAM allows you
to open additional 3D windows and store additional 3D
textures.
To obtain a memory module upgrade, please contact ATI
or your dealer. For information about contacting ATI, click
the ATI icon in the ATI Displays control panel.
