Why is my ram at 667 instead of 800

I have just bought PNY 2GB dual channel memory kit. On the box it says 800, 667, and 533. My computer's current ram is at 800 but when i install it it is at 667, how can i fix this?

My motherboard is ECS a780gm

    First... You have mixed RAM so your faster RAM will run at the slower speeds of your new RAM.

    Second... You will need to go into your BIOS and adjust your new RAM to match your old RAM to get both of them at 800Mhz.
  2. So i manually clock it to 800, is that overclocking my ram?
  3. You want the speed (DDR2 1066 Mhz), Timings (5-5-5-24-2N) and Voltage (1.65V) to match for all of your RAM in your BIOS [Numbers are examples not true settings].

    It may or may not be overclocking your RAM. You may have to down clock your original set to be stable... Just maybe.

    Try a minimum of 1.8-1.9 volts when using DDR2 unless your RAM states lower like a Green series low voltage.
