Basics SGRAM Video Memory - 16
SGRAM Video Memory
The Power Macintosh G3 logic board comes with 2 MB of
Synchronous Graphic RAM (SGRAM) video memory soldered
on. The logic board also contains a video memory expansion
slot that accepts a Small Outline DIMM (SO-DIMM) to
increase video memory up to a maximum of 6 MB. Apple
supports a 4 MB SGRAM SO-DIMM that is 32-bit wide,
144-pin, fast-paged, 100 MHz/10 ns cycle time or faster.
Important:
Use only SGRAM SO-DIMMs. Never use the 256K
or 512K video memory DIMMs used in older Macintosh
computers.
