  1. Looks like dual channel memory. Use two sticks DDR2 533, here for example.
  2. Thanks for your help !!

    As I understand there is two slots in my motherboard. So Can I go with the below mentioned configuration
    1) One slot - 512 DDR2 RAM (RAM which is currently in use)
    2) Second slot - I will add my new 2GB DDR2 RAM

    In this way I will get 2.5 GB RAM. Can I go with this configuration and also let me know what should be the mhz I should buy for the 2GB RAM ?

    My Processor is Dual Core not Core 2 Duo
  3. Best answer
    I found your motherboard manual here. Pages 9 and 13 shows the RAM slots support 1 GB each, page 9 shows you can use 533/400MHz RAM modules. I would recommend you get 2 1GB 533MHz RAM modules, they are easier to find.

  5. Thanks for your help !! It has cleared my doubts

    Is there any workaround :kaola: beacuse in this case i have to remove my 512 Ram and then I have to add 2 1GB RAM. But I would like to have a 2GB and my 512 ram . Is it possible to increase my maximum memory limitation from 2 GB to 2.5 GB by installing drivers for my motherboard ?
  6. You're welcome. You have two DIMM slots, and Intel says each can only read 1 GB.

    If you want to take the chance that your board can really see 2 GB in the DIMM slots, you could buy 1 stick of the RAM in the links above, and 1 of these sticks. That would equal 3 GB of RAM.
  7. Hi
    this is kishore, one of my friend had same issue we tried, The board will not support 1 + 512 it can only support 1 + 1 in slot and it will not support stand olone 2 unit will not show display its an old board and calculation will only addup to 1 + 1
