RAM Frequency Not Displaying Properly.

  1. I just bought a new system that includes a mobo with a DDR2 800 memory standard. The RAM installed is DDR2 800 4-4-4-4-15-1T SLI Ready (mobo is SLI ready as well). I set the BIOS to read the RAM as exactly what it is - DDR2 800, 4-4-4-4-15-1T. When I open up cpu-z and go to the memory area, it shows both of my sticks running at 400MHz!

    Something's wrong here... anyone have any ideas? The timings are correct, and it displays PC6400 like it should, but the MHz is all wrong.

    lol dont panic, everything is fine, remember ddr2 is dual pumped, so 400x2 equals what, lol just kidding, but yeah that's how cpuz shows stuff, your system is fine!

    ddr means double data rate. it runs at 2 x 400mhz = 800mhz.
    don't mess with timings on ram, you can really wreck things.
    set it for automatic and leave it alone.

    Whew... thanks a lot guys. That DDR thing totally slipped past me. I learned that stuff in a college course but I was so caught up in worry that it slipped my mind!

    Thanks again.
