DDR2 Memory -- faster = better?

  1. Hello,
    I need to buy memory for a ECS P4M800PRO-M v2 motherboard with a Pentium D 805 CPU. This system normally runs a 133 MHz bus clock giving specified 533 MHz memory speed.

    However, I am planning to experiment with overclocking, so thinking to buy 667MHz (PC2-5300) or even 800MHz (PC2-6400) memory.

    My question is, will this faster memory work at the normal 533 MHz speed, in case the overclocking does not work...?

    Has anybody run a system with faster memory than specified... or have any comments...?

    this should work; the memory will just run at the slower speed.

    Make sure you buy high quality memory. Check the recommended memory list for the mobo, and buy sticks that closely resemble the recommended ones if you're buying faster ram.

    Yes the RAM will run fine and if the OC doesn't work it will switch back to 533MHz. Just get high-quality RAM like gavilan said to reduce the chances of failure.
