As the Grackle IC memory controller and PCI bridge on the Gossamer and Artemis logic boards supports only linear memory organization, no benefit accrues from installing SDRAM DIMMs in matched pairs, and DIMMs (installed in any slot and any order) are addressed as a contiguous memory array.Īlthough Apple technical documents state that the densest DIMM supported by the Gossamer and Artemis main logic boards is a dual-banked 128MB DIMM using a maximum of sixteen 64Mbit SDRAM devices, testing has demonstrated that max configurations of 768MB are feasible in these three-slot machines using three 256MB SDRAM DIMMs employing thirty-two CMOS 16Mx4 bit Synchronous-DRAM devices in a 1.15-inch high form factor.


The Power Macintosh G3 Minitower (Artemis) has three SDRAM expansion slots. We appreciate your technical corrections and comments !
