    Anyone knows if E6400 supports DDR3? I checked others (e.g. Lenovo, HP, etc) they all support DDR3. I am not sure how "significant improvement" a system will achieve with DDR3. But it will be nice to have latest tech.

    ~4% bandwidth inc with DDR3-1066 over DDR2-800.

    No DDR3 for the E6400, the slot is different.

    The performance difference is very small, especially when you consider the price of DDR2 RAM.

    Performance difference is not noticeable, but DDR3 operates at 1.5v compared to 1.8v for DDR2. I dont know what kind of power savings that translates to, but it does mean something :)

    DDR3 requires a different RAM slot, which the E6400 does not have.

    The DDR2 slots also mean that you can re-use your old RAM - 667MHz doesn't make a significant drop in performance. The key point is that the new Intel chipset has higher bandwidth than the old one. See part 2 of my E6400 review for some numbers.

    you usually want the CPU, FSB and Memory speed to match to prevent bottleneck. Meaning, you can significantly reduce your system performance if you have slower RAM, which leads to a system that is less responsive, and could potentially use more battery life, as the system needs to me longer active as it has to wait for everything to catch-up.

    Intel's caching techniques generally hide this performance problem.
