Test Results: Single Vs. Dual Channel RAM

Let’s now answer the more important question: is dual channel memory really worth it?

3D Benchmarks

3DMark06 only cares about high graphics and CPU performance. It doesn’t seem to mind us switching the 2 GB total main memory from dual channel to single channel operation.

Call of Duty 2 runs approximately 4.2% slower on the same hardware when dual channel mode is not used.

The performance difference in Prey is very small: 1.6%.

There is even less of a difference under Quake IV.

(Firt of all: Excuse my poor English... )
mmm yours memory tests don't convince me. You should run, for example, Winrar AND Lame IN PARALLEL/SIMULTANEOUS (i.e multitasking), otherwise, caches don't are flushed (and it's when dual channel really is important). Note that it's not a superflous situation; under normal use a system commonly have several huge memory applications run concurrently (word, browser whith a lot of tabs open, anti-virus, etc. )
