Earlier in the year Corsair launched the low-latency RAM geared specifically for the Penryn-based MacBook and MacBook Pro, which I currently have on my MBP, and now they’re kicking out some kits for the Mac Pro. The new Mac Memory kits buffer at 800MHz and work alongside the MP-specific heat sinks and whatever else to unleash the beast that is your Mac Pro. A 4GB DIMM kit retails for $250 and all Corsair Mac memory are put through the ringer at Apple Test Labs.
