More about extending
  1. The most your board can take is 4GB of DDR2 667 so you could look for a set of 2X2GB DDR2 667

    For example.... http://www.newegg.com/Product/Product.aspx?Item=N82E16820226088&cm_re=ddr2_667_4gb-_-20-226-088-_-Product

    As listed on your motherboard specification sheet....

    1. 4 DDR II DIMM memory slots (supports up to 4GB memory)
    2. Supports 1.8V DDR II DIMM
    3. Supports dual channel DDR II 667/533/400 DIMM
  2. So it won't use more than 667Mhz?
  3. Pls refer to their website for more info -


    It has a bios update so your mobo can support new cpu.

    You can put 800mhz memory in it if you want, but it will still run at 667mhz. That is the speed the memory for your processor runs at.
    Memory speed is not dictated by what kind of memory you install, memory speed is dictated by the speed of the FSB of the CPU you are running, and you buy memory to match those specs.
    You can put in 800mhz if you like, but it will still run at 667mhz.
    You can put in 800mhz, change the memory divider and force it to run at 800mhz, and you won't be able to tell any difference from when it was running at 667mhz.
    So, the most cost effective thing to do is simply add some more 667mhz memory to what you have.

    BUTTTT...it looks like from the post above that the max your board will support is 667 anyway. So just buy more, and be happy knowing you are doing the best you can for your system.
