Well, the situation doesn’t look very good for Corsair TwinX1024-4000PRO, to tell the truth. The advantages provided in synchronous mode is pretty stable and hardly exceeds 1%. Asynchronously working DDR400 modules with aggressive memory timings ensure about the same performance, and in some tests, like WinRAR or Unreal Tournament 2003, they even provide a significant performance improvement. This way, the resume is not very positive: using Corsair TwinX1024-4000PRO in today’s typical systems doesn’t have any worthy advantages.
