    Would it make any sense to upgrade the memory on a 1530 to 800mhz memory? Would it be faster?

    No. The Santa Rosa chipset doesn't support DDR2-800.

    533 and 667 memory performs roughly the same, and even if 800 was supported you would not see any performance improvements really. Just a bit of info for you :rolleyes:

    I believe Montevina is going to move from DDR2-667 RAM to DDR3-800 RAM.

    Correct me if I'm wrong.

    I'm going to have to say you didn't.

    I've seen that info there before. :)

    i think even the penryn which is being announced on january 7th by Intel's CEO at CES will support the 800MHz RAM.

    Wouldn't DDR2 800 run at a lower latency then DDR2 667, when downclocked?

    exactly. ddr2 667 runs at CL 5... ddr2 800 also runs at cl 5, but on my m1530, since it only runs at 667 :( it runs at cl 4. so i have faster timings which is nice.

    RAM latency isn't so much of an issue, these days. CPU's have such good prediction technology, large caches and interleaved / dual-channel memory access that it virtually eliminates any benefits of low latency RAM.

    I've got some old 2-2-2-5 DDR1 in my desktop machine and it made no difference to real-world performance. Only a couple of synthetic tests showed a difference (and then less than 2%). It's probably no coincidence that you can't buy extreme low-latency RAM these days (at least, not from most of the popular outlets).
