However, with only a simple, single-track project open, Premiere used merely 214MB of RAM–it did not take up the entire 6.5GB, and my system ran perfectly well with several other applications open. On my 8GB system, the default setup reserved 6.5GB for Premiere and 1.5GB for everything else. However, I had none of the RAM-related problems I’ve occasionally encountered with Premiere Pro CS4–none of the slow reading and writing of data to the hard drive instead of to RAM, fewer playback and timeline scrubbing hesitations, and generally smoother operation overall.Īs with the 64-bit Photoshop, Premiere Pro requires that you allocate RAM manually–up to a maximum of 128GB. Relying on CPU power, Premiere Pro CS5 didn’t render any more quickly than Premiere Pro CS4 did. When I installed a beta version of Creative Suite 5 on my test system, a dual-Xeon workstation running Windows 7 64-bit with 8GB of RAM, I did not notice a substantial improvement in rendering speed–but then, my workstation doesn’t have one of the approved graphics cards.
