General Information


PowerPC G3 microprocessor running at a clock frequency of 233 MHz, 266 MHz, 300 MHz, and 333 MHz depending on model and configuration. 66 MHz Apple RISC system bus.


0 MB soldered on the main logic board; expandable to 768 MB using 64-bit (non-parity) 168-pin JEDEC-standard 3.3-volt unbuffered SDRAM (synchronous dynamic access memory) DIMM (dual inline memory module) cards. Three DIMM card slots are provided for DRAM expansion. A minimum of 32 MB of RAM is installed in one of the DIMM card slots.


2 MB synchronous graphics RAM (SGRAM) frame buffer on the main logic board. Video memory can be expanded to 4 MB or 6 MB with an optional 2 MB or 4 MB SGRAM graphics memory module.


512 KB or 1 MB of back-side second-level (L2) cache on processor module (depending on model and configuration). The cache runs at one half the clock frequency of the microprocessor. For example, the cache would run at 166.5 MHz on a 333 MHz processor module.
