How much RAM should I buy?

At the moment I'm in the process of upgrading my pc. I have a pair of 2GBs sticks on my motherboard and I have 2 more slots open.

I know that whatever I do, I have to buy same frequency RAMs as the ones I have on at the moment.

But are there any limitations regarding the size?

I would like to upgrade as much as possible, so is it worth getting a pair of 4GBs Rams to have a total of 12GBs? Or would that make memory management more difficult and would be more efficient to just get 2 more 2GBs rams and have a total of 8GBs.

P.S. They are DDR2.

    8 Gigs of ram is more than enough for regular PC with moderate to high gaming. no need to get more unless you plan to do a lot of video editing and 3D rendering.
    Also your ram is DDR2 which is kind of out dated now, so getting a bigger and costlier ones will be a one way trip as you can't carry them over to any current generation boards if you decide to upgrade your system in the future. All current motherboard model uses DDR3 RAM.

    I would rather suggest to stay with the 4 gigs you have and plan a future upgrade to a new system.

    Check you motherboard RAM limit size before spend the money... some older motherboards doesn't support 4gb or 8gb modules...
    Buy as much as you can! :)

    Only one comment, DDR2 is not common right now, you can buy some modules with higher frequency than the ones you found on your system (they can run at lower speeds if you set to), in the future, if you need to upgrade (think it will not be a good choice, better get all new components, you can replace the 2 modules you already have), you will finish with higher frequency for all the slots! :)
  3. Check your system, i dont think it allows you upgrade max 12GB....
    I would suggest you to stay with the 4GB and if you still want to upgrade it then add 2GB in it,
    as DDR2 is not common and expensive.

    I would recommend you to upgrade your new system and switch to DDR3 RAM.
  4. Thx for the replies guys. I will upgrade almost everything except my motherboard and processor because they are pretty decent (Quad Core AMD) and I don't think its worth the extra expense yet. I'll try to find another pair of 2x 2GBs memories then (used most likely) to get to that 8GBs total. I will most likely not buy new ones cause they are indeed very expensive.

    Just make sure that your motherboard is compatible with 8 gigs of RAM. Many old motherboard doesn't support that much RAM. You will get the information from motherboard manufacturer's website.
