Reviewed: 8GB memory modules for Apple Mac Pro Nehalem
Just posted is my review of the OWC 8GB memory modules for the Apple Mac Pro. Also shown are Photoshop CS4 results for the diglloydHuge benchmark, and yes, 64GB does pay off for monster files.
With 8GB modules, you can take your quad-core Mac Pro to 32GB, an option that might well prove useful as more software moves to 64-bit capability in 2010. An 8-core Mac Pro can go to 64GB, but you do need to boot into the 64-bit Mac OS X Snow Leopard kernel.
