VRAM conÞgurations
Video memory (VRAM) for the two ports on the optional high-performance video card is
provided in SIMMs installed on the card. (The standard monitor port does not use VRAM.)
The high-performance video card comes with 2 MB of VRAM and can be expanded up to
4 MB with four 80-nanosecond, 68-pin, 512 KB SIMMs.
Increasing the computerÕs VRAM increases the number of colors that can be displayed on a
monitor. See the tables in the next section for information about how many colors can be
displayed on a monitor of a particular size with different amounts of VRAM.
Monitor resolution/color tables
The following tables display the numbers of colors available to monitors of various sizes
connected to the computerÕs monitor ports. Table D-1 displays information about the DRAM
video monitor port. Table D-2 displays information about the standard monitor port located
on the optional high-performance video card, including color levels available with different
amounts of VRAM. Table D-3 lists the same information for the VGA port on the optional
high-performance video card.
