RAM FOR MAC PRO 2007 MAC OS X
However, Photoshop testing with large files disproves this Mac OS X caching puts extra memory to valuable use on any Mac. This includes programs like Photoshop CS4.Īt first glance, this limitation would suggest that having more than 8GB or so of memory would be pointless. 32-bit vs 64-bit applicationsĪlthough the Mac Pro allows installation of up to 32GB RAM, nearly all applications are still 32-bit, which means they cannot use more than an absolute maximum of 3.5GB (less in practice). Having “extra” memory of 1-2GB is an excellent investment in improving overall system response, especially if you regularly launch and quit programs, or your programs work with large files. Of course, this cannot occur with too little memory, and the responsiveness of your Mac will suffer.

That’s because Mac OS X retains the application’s code and data in memory even after quitting. You should find that it starts up considerably faster the 2nd time (assuming you have adequate memory). Launch an application, then quit it, then launch it again. It is highly effective! Caching is unlimited: Photoshop test results show that all available memory in a 32GB Mac Pro can be used! Mac OS X uses disk caching (unified buffer cache) to speed up the launching of programs and reading/writing of files. Want a top-performing Mac Pro pre-configured and pre-tested? See this page. has some testing results on the new memory speed. Together, those two improvements raise memory bandwidth significantly, making the performance of 8 cores notably better than before (for the few programs that can exploit 8 cores). There is also support for 800MHz memory, up from the 667MHz memory tested for this article in the previous generation Mac Pro. The 8-core Mac Pro (introduced Jan 2008) includes the latest Intel Xeon processors with larger on-chip caches, and a new top clock speed of 3.2GHz. While the Mac Pro memory discussed on this page is for the original quad-core Mac Pro, the installation, performance and reliability issues are identical for the 2nd-generation (8-core) Mac Pro. However, even if your needs are modest, adequate memory is as important on the Mac Mini as on the Mac Pro, so this discussion should still be of use. This page assumes that you’ve purchased a Mac Pro for work with digital images, video, sound, etc-if you’re simply browsing the web, working with email (personal or business email), twiddling around with iPhoto, the Mac Pro is overkill-those needs are easily served using an iMac or MacBook with 1GB or 2GB of memory.

Photoshop users working with large files will want to read Optimizing Photoshop, which provides clear guidance on how to determine the amount of memory needed, and performance results with 8/16/32GB. See the Mac Pro Nehalem review for specifics on the March 2009 Mac Pro. This page covers general material on Mac Pro memory, and specifics on memory for the 2008 and earlier Mac Pros. See also Checking memory use on Mac OS X and How to Select and Configure a Mac Pro. Please refer to How to Choose and Buy a Mac and its related pages for important background material.
