    Thanks, but I was really wanting to know is the difference between the "pc" and "pc2"
    designation on ddr2 memory. Nevertheless, I appreciate your willingness to take the time to help.
  3. Do you have a site where you've seen both listed next to each other? Also, what is the next number when you see this diplayed? (e.g DDR2 PC6400. PC 2 6400?)
  4. Best answer
    The pc"x" is just another way to indicate which type of DDR ram it is. all ddr2 ram is pc2.
    there are two ways to classify ram, either: pc2 6400 or DDR2 800.

    PC is just a number that is the result of the MHz multiplied by 8.

    PC3200 = DDR 400MHz

    PC2 6400 = DDR2 800MHz

    Thank you for the help. I believe my confusion began when I sought help from the "expert" at my local Staples. I believe I understand now.
