    I guess it's the late 2006 one. Plastic casing. DDR2 667MHz RAM.

    The maximum is 2 GBs - two - 200-pin PC2-5300 (667MHz) DDR2 SO-DIMMs.

    Hi.

    I have a white iMac 20-inch (Late 2006) with Intel core2Duo 2.16GHZ Processor and I want to upgrade my memory. My system reports for memory these:

     

    Memory Slots:

     

      ECC:          Disabled

     

    BANK 0/DIMM0:

     

      Size:          1 GB

      Type:          DDR2 SDRAM

      Speed:          667 MHz

      Status:          OK

      Manufacturer:          0xCE00000000000000

      Part Number:          0x4D342037305432393533435A332D43453620

      Serial Number:          0xF71B7551

     

    BANK 1/DIMM1:

     

      Size:          1 GB

      Type:          DDR2 SDRAM

      Speed:          667 MHz

      Status:          OK

      Manufacturer:          0xCE00000000000000

      Part Number:          0x4D342037305432393533435A332D43453620

      Serial Number:          0xF71B73E1

     

    I have read a lot of things about this, but I was wondering which is the best choice for this upgrade.

    My questions are:

     

    -Can I install DDR2 SDRAM or SO-DIMM DDR2 or both?

    (Here apple writes and copability for DDR3 SDRAM for my model???)

     

    -I have read that iMacs with installed 4GB Memory (2GB+2GB )have better response and speed from these with 2GB+1GB Memory. Is that true?

     

    -I have to looking for dual channel memory or not?

     

    -Memory's speed must be 667MHZ or 800MHZ or both of them can be istalled to my machine (not at the same time)?

     

    -My memory must have 200pin?Because SDRAM DDR2 have 240pin!

     

    -And finally memory's voltage must be 1,5V or 1,8V?

     

    Pleasy can you help me?
