Quadra 900, Quadra 950Low End Mac Reader Specials
The Quadra 900 and 950 have no RAM on the motherboard and 16 SIMM sockets for memory expansion. With the rear of the computer away from you, you will see four banks of four SIMM sockets at the front of the motherboard. Because the 900/950 uses older 30-pin SIMMs, you must install memory in banks for four. Each SIMM socket can be filled with a 1 MB, 4 MB, 8 MB or 16 MB SIMM, giving a maximum capacity of 256MB! You can use different capacities in each bank. The 30-pin SIMMs must be 80ns or faster. (Note that Apple doesn't officially support 8 MB and 16 MB SIMMs in these Quadras.) Unlike earlier Macs, there is no need to put higher capacity memory in a specific bank. VRAMThe 900/950 ships with 1 MB VRAM on the motherboard. You can upgrade this to 2 MB by installing four 256 KB or 512 KB VRAM SIMMs in the four VRAM sockets on the left side of the motherboard. (The 900 and 950 only see 256 KB on 512 KB VRAM SIMMs.) <go to memory upgrade index, Quadra 900, or Quadra 950> Low End Mac is an independent publication and has not been authorized, sponsored, or otherwise approved by Apple Inc.
