Memory can be added using four matching 1 MB, 4 MB, or 16 MB SIMMs. The 30-pin SIMMs must be 80ns or faster.

Memory capacities are 4 MB (stock), 8 MB (with 1 MB SIMMs), 20 MB (using 4 MB SIMMs), and 68 MB (with 16 MB SIMMs, which are not officially supported by Apple).

VRAM, Where More Memory Means Less Speed

The Quadra 700 ships with 512 KB VRAM on the motherboard. You can upgrade this to 1 MB by installing two 256 KB or two 512 KB VRAM SIMMs in a VRAM Bank B. For 2 MB VRAM, install six 256 KB or six 512 KB matching VRAM SIMMs, filling all VRAM sockets. (Note: The Quadra 700 sees only 256 KB of a 512 KB VRAM SIMM.)
