Use the iMac identification system to help you identify your machine. The PowerPC 604e was the first Mac processor available in a symmetric multiprocessing (SMP) configuration.You can verify that you have a iMac Intel 20" EMC 21 by checking the processor information through "About This Mac" in the Apple menu. /rebates/2fshop2fapple2fmemory2fiMac2fIntelCore2Duo&. The PowerPC 601 was the first Mac processor to support the 32-bit PowerPC instruction set architecture.Ī Motorola PowerPC 603 processor Processor according to Mactracker the mid 2007 imac 20inch has: Maximum Memory 6.0 GB (Actual) 4.0 GB (Apple) Memory Slots 2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM. Use 1GB, 2GB, or 4GB modules in each slot for the iMac (Early 2009). The MC68LC040 version was less expensive because it omitted the floating-point unit. You can use a 1GB or 2GB RAM module in each slot for iMac (Mid 2007) and iMac (Early 2008). The Motorola 68040 has improved per-clock performance compared to the 68030, as well as larger instruction and data caches, and was the first Mac processor with an integrated floating-point unit. you should also make sure that you always have the same amount on both slots in your case two 3gb however 3gb rams are rare therefore more expensive. Both models can actually use double Apple's max spec (32GB and 16GB respectively. according to Mactracker the mid 2007 imac 20inch has: Maximum Memory 6.0 GB (Actual) 4.0 GB (Apple) Memory Slots 2 - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMM.

For iMac (Mid 2010) and iMac (Mid 2011), use 2GB or 4GB RAM SO-DIMMs of 1333MHz DDR3 SDRAM in each slot. Mactracker lists a Mid-2011 iMac 27', not Late-2011, which is a 21' screen. Another improvement over the 68020 was the addition of a data cache. For iMac (Late 2009), you can use 2GB or 4GB RAM SO-DIMMs of 1066MHz DDR3 SDRAM in each slot. The Motorola 68030 was the first Mac processor with an integrated paged memory management unit, allowing for virtual memory.
