  1. No there is no danger running those two together.
    Just set both RAM frequency to 667Mhz in the bios.
  2. Bios :(

    i have asus Mobo p5n73-cm where is this ram frequency option ?

    ... any software ??
  3. it's auto by default. BIOS will knows to run the slowest memory. Furthermore, it's works but also took additional performance hit by forcing the overall ram to run in single channel. Stick in another matching 667mhz 1GB Ram will bring it back to dual channel.
    MS rating is misleading-score on amount of ram not performance.
  4. some motherboards will work fine with 2 sticks of RAM that are rated at different speeds while others will not. Luckily your mobo seems to work fine.
