Memory. An integral part of every computer, the bank of system RAM (random access memory) is the place, outside the CPU's own cache, where data gets stored for the short-term as it gets sent to the main processor by programs and returned after calculation.
This article sets out to try to answer all kinds of memory questions herein. Using nearly identical motherboards to test both DDR2 and DDR3, we ran all kinds of performance tests, subjective and repeatable, synthetic and real-world. We played and benchmarked games, crunched huge amounts of data, and ran Windows with tons of stuff open.
