Notes

The Quadra 800 memory circuitry allows any supported SIMM size to be installed into any SIMM socket in any order, and they can run with partially populated banks. It doesn't support 1MB, 2MB, or 64MB SIMMs. The Quadra 800 uses "memory interleaving" which occurs when like SIMM pairs are used (for example: two 8MB SIMMs). This allows the memory subsystem to perform certain operations faster. Basically, it allows the memory subsystem to write to the same memory address in different banks of memory before incrementing the address. Depending on how memory intensive the application, this can improve performance 5 to 10%. DO NOT USE COMPOSITE SIMMS IN THE QUADRA 800!!

32-BIT Information

This system has 32-bit-clean ROMs allowing it to take advantage of more than 8MB of physical RAM under System 7 by enabling 32 bit addressing in the Memory Control Panel.

VRAM Information

The Quadra 800 VRAM can be expanded to 1MB by installing two 256K VRAM SIMMs rated at 80ns or faster.
