The current SPECcpu2000 memory footprint is designed for 256Mb computers. The new SPECcpu2004 will probably increase this to 1Gb. Registered memory is really a must if you want to run more than 1Gb without timing degradations due to the 4-bank optimum limit per memory channel. As it happens I think 1Gb is just about optimal for a general-purpose PC. I upgraded from 512Mb because of eventual extensive swap-file usage when running many applications for hours, this has now been cured. Most versions of Windows won't normally exceed 1Gb memory usage in general-purpose 32-bit application usage.
