Centris 610 and Quadra 610Low End Mac Reader Specials
The Centris 610 and Quadra 610 have 4 MB of RAM soldered to the motherboard and two 72-pin SIMM sockets for memory expansion. With the rear of the computer away from you, you will see 4 SIMM sockets on the right side of the motherboard. The front two sockets are for RAM; the rear two for VRAM. Each RAM socket can be filled with a 4 MB, 8 MB, 16 MB, or 32 MB SIMM - they need not be of the same capacity. (There is no support for 1 MB, 2 MB, or 64 MB SIMMs.) The 72-pin SIMMs must be 80ns or faster. If you install two SIMMs, they should match in speed or you may have memory problems. If you match the speed and capacity of both SIMMs, the 610 will use memory interleaving, which can be 5-10% faster. Unlike earlier Macs, there is no need to put higher capacity memory in a specific bank. VRAMThe 610 ships with 512 KB VRAM on the motherboard. You can upgrade this to 1 MB by installing two 256 KB VRAM SIMMs in the VRAM sockets beneath the floppy drive. <go to memory upgrade index, Centris 610, Quadra 610 or Quadra 610/DOS> Low End Mac is an independent publication and has not been authorized, sponsored, or otherwise approved by Apple Inc.
