    This sounds like a strange question. I got the computer in a trade with someone else. Crucial's program says I can use 200-pin SODIMM, DDR2 PC2-6400


    When I go into system profiler it says I have this
    Size: 1 GB
    Type: DDR2 SDRAM
    Speed: 800 MHz

    Why is it showing 800mhz only? Is that even possible?

    My second question is this. I have 2 sticks of RAM from my old macbook that are 512MB each that are PC2 5300. Would it be faster if I put 1 or both of those in instead of the DDR2 800mhz RAM?

    That's the speed of the RAM, not the CPU - and it sounds right. Putting in those 2 512 MB sticks would not be any faster - it might be slower, as the older RAM may have a slower speed, if it is even compatible with your iMac.

    If you really want a speed / performance boost, go to OWC or Crucial or Ramjet and grab a 4 GB set of RAM (it's really cheap right now), and max that baby out!

    What model of iMac is it? That's really rather important in determining what RAM you need.
