WinRAR is thread-optimized and very memory sensitive, so it runs significantly faster on fast memory settings. “Fast” is defined by both high clock speeds and low latencies.
WinZip doesn’t care if you install faster memory. Performance is almost unchanged unless you only use DDR3-800 RAM, which most people probably wouldn’t do.
Pinnacle Studio is a video editing application that scales nicely with faster memory and quicker timings.
Video editing on Adobe Premiere Pro CS3 doesn’t show many differences among the setups we used.
