> I'm interested in using voice-recognition software. In a different vein, I see that you'll have some software updating to do.doesn't look particularly costly (to me) and that you're running some obsolete software, but what jumps out at me is that you're using AppleWorks, which may present a problem. Doc #3 also says: " For best performance, fill both memory slots, installing an equal memory module in each slot", but, again, your situation is anomalous. Judging from your list of apps that you run, I'm not certain that you'd derive any particular benefit from it.Įdit: 4. I've got no idea whether it works, even with matched DIMMs, with a Mac that doesn't recognize all the memory it's got.ģ. Interleaving requires the same size DIMM in each of the two slots.Ģ. The only potential limitation I've run across deals with RAM interleaving, which, if your iMac supports it (Edit: Doc #3 suggests that it does, and Mactracker says " Yes".), will give you (what I believe is only) a minor speed boost:ġ. The PowerPC 604e was the first Mac processor available in a symmetric multiprocessing (SMP) configuration.The computer will only use a maximum of 3 GB of RAM. PowerPC 604 An IBM PowerPC 604e processor PowerPC 603 A Motorola PowerPC 603 processor Processor The PowerPC 601 was the first Mac processor to support the 32-bit PowerPC instruction set architecture. OWC 4GB PC5300 DDR2 667MHz SO-DIMM Memory Compatible with MacBook (Late 2007/Early 2008), MacBook Pro (Mid/Late 2007, Early 2008), & iMac (Late 2007) Systems with Core 2 Duo Processor. PowerPC PowerPC 601 An IBM PowerPC 601 processor The MC68LC040 version was less expensive because it omitted the floating-point unit. You can see below that upgrading the RAM in a 27 iMac is a simple job. 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. GHz Quad-Core Intel Core i7 - Easy access, upgradable RAM + SSD - Graphics Intel. ![]() Motorola 68040 A Motorola 68040 processor every indication I have seen on MacTracker, BEETSTECH and iFixit is that the. Buying options 667MHz DDR2 PC2-5300 - Maximum 6GB supported. For iMac (Mid 2010) and iMac (Mid 2011), use 2GB or 4GB RAM SO-DIMMs of. Backed by an OWC Limited Lifetime Warranty. Another improvement over the 68020 was the addition of a data cache. All installed memory should be the same speed for best performance. The Motorola 68030 was the first Mac processor with an integrated paged memory management unit, allowing for virtual memory. Motorola 68030 A Motorola 68030 processor The Macintosh LC configured the 68020 to use a 16-bit system bus with ASICs that limited RAM to 10 MB (as opposed to the 32-bit limit of 4 GB). Apple officially supports 4 GB of RAM, but third-parties have been able to upgrade the system to 6 GB of RAM using one 2 GB and one 4 GB memory module. Details: 1 GB of RAM is installed as a single SO-DIMM module. The 'Mid-2010' iMac models include a compact aluminum Apple Wireless Keyboard and a multi-touch 'Magic Mouse,' but for US69 could be upgraded to include a multi-touch 'Magic Trackpad' that 'enables users to scroll smoothly up and down a page with inertial scrolling, pinch to zoom in and out, rotate an image with their fingertips and swipe. The 68020 has many improvements over the 68000, including an instruction cache, and was the first Mac processor to support a paged memory management unit, the Motorola 68851. 1 I was looking at macsales for memory for our new iMacs which are on their way here and noticed that it says the Mid 2007 iMacs we have can support 6GB RAM. Assuming your machine is either this 20' or a 24'. The Motorola 68020 was the first 32-bit Mac processor, first used on the Macintosh II. Motorola 68020 A Motorola 68020 processor ![]() ![]() It has 32-bit CPU registers, a 24-bit address bus, and a 16-bit data path Motorola referred to it as a "16-/32-bit microprocessor." Processor Memory Upgrades for Apple iMac 2007 - Up to 6GB Home Mac & PC Memory iMac 24' & 20' iMac (2007) Actual product may differ slightly in appearance. No, according to the Apple database, both the 21.5 and 27 Late 2009 models cannot run anything newer than Mac OS 10.13.6. The Motorola 68000 was the first Apple Macintosh processor. Motorola 68k Motorola 68000 A Motorola 68000 processor in a dual in-line package, as the early Macintosh models used It is grouped by processor family, processor model, and then chronologically by Mac models. This list of Mac models grouped by CPU type contains all central processing units (CPUs) used by Apple Inc.
