Hi, wondering if anyone can please help me with RAMS. I recently purchased a used MP 2008 3,1 for the purpose of doing some photo editing with Adobe CS6 and video editing using FCP X, Adobe Premiere. The system has the following RAMs: Riser 1: 4GB ddr2-5300F 667 Mhz 4GB " 1GB ddr2-6400F 800 Mhz 1GB ddr2-6400F 800 Mhz Riser 2: all slots with 1GB ddr2-6400F 800 Mhz Under About My Mac, shows total 14GB @ 667 Mhz Of course, they only run at the lowest speed........ my questions to what should I do to optimize/maximize the performance: (1) should I leave it as is or should I remove the two 4GB 667 Mhz and stick with only 6GB 800Mhz? (2) Since the system is used for photo and video editing, should I might as well max out to 32GB? The question is will I notice the difference in performance if I get 32GB 667Mhz as oppose to the more expensive 800Mhz? If 800Mhz gives better performance, I'd rather pay the extra bucks to achieve that.
