The display memory on the main logic board is separate from the main memory. The display memory consists of 2 MB of 100 MHz/10ns SGRAM devices configured to make a 64-bit data bus. The display memory can be expanded to 4 MB or 6 MB with a 2 MB or 4 MB SGRAM SO-DIMM card.
With the 2 MB of built-in video memory the display data generated by the computer can have pixel depths of 8, 16, or 32 bits for monitors up to 832 by 624 pixels, 8 or 16 bits for larger monitors up to 1152 by 870 pixels, and 8 bits for monitors supporting 1280 by 1024 pixels. Data from the video input module is always stored and transferred at 16 bits per pixel. The video frame buffers support live video in a 320-by-240 pixel frame at 30 frames per second. For a complete listing of the supported monitors and display resolutions, see Video Input and Output .
The 100 MHz/10ns SGRAM SO-DIMM card specification provides suitable margins for compatibility with the Power Macintosh G3 computer architecture.
