Notes

The Quadra 840av has a flexible memory system, meaning that any supported SIMM size can go into any SIMM socket in any order, and they can run with partially populated banks. It doesn't support 1MB, 2MB, or 64MB SIMMs. DO NOT USE COMPOSITE SIMMS IN THE QUADRA 840av! Although based on the Quadra 800 logic board, the 840av has no memory soldered to the logic board.

32-BIT Information

VRAM Information

The Quadra 840av has 1MB of VRAM soldered to the logic board and four SIMM slots for expansion. Four 80ns 256K VRAM SIMMs are required for expansion to 2MB.
