    So, I hear through the vine that the CPU of the MBP (current gen) has a frontside bus of 800MHz, but only came with RAM at 667MHz.

    I am in the market to upgrade to 4GB of RAM in my MBP. Will I get a little bit more of a speed bump moving to the DDR2-800 RAM?

    No. Will run at same speed. FSB different from RAM speed.

    It isn't as easy to overclock the memory on the Mac as it has been for PCs.

    There were some people tinkering with the EFI settings when the Intel machines first came out, but the those threads have thinned out.

    Hmm. I am not looking to over clock, but if I remember correctly from my PC days that if you used RAM that was slower than the FSB of your processor, the processor would slow its FSB down to match the RAM..

    Is that happening in the MBP?

    the SR chipset can only support up to 667 ram. All SR laptops have the same issue.
