Help me understand having a 64 bit system and memory usage

Hello

I have a Dell XPS 420 with a q6600 with 4 gigs of 667 MHz DDR2 ram. I installed Windows 8 64 bit onto the computer.

I can upgrade up to 8 gigs. Is there any need for me to upgrade to more ram right now?

I play games, watch video, do some Photoshop stuff on it and some basic 2d and 3d design on it.

I am building a new system but will keep this old computer.

  1. G335, sorry I got your wrong answer for last post. The 420 can support up to 8GB RAM. Here is from Dell.

    If you are building the new PC, don't put more money on the old LGA775 PC. I add the link for DDR2 8GB RAM (4x2GB) and they cost $150. It is not worth. http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007611%20600006042%20600006071&IsNodeId=1&name=8GB%20%284%20x%202GB%29

    Thank you.

    Since I am running a 64 bit os on it, and doing things that I mentioned above, would it be worth it to put the 8 gigs in it or 6? I will not put more into this computer unless its necessary.
  3. Because you do use the PC for some Photoshop and 2D/3D design and if you want you just add 2GB more. And you don't need more RAM if you won’t be able to feel the PC lag.

  4. As stated, it's not worth throwing a lot of money at your old system. How is the current RAM configured? Is it occupying 2 slots or all 4? If you were to try to match the memory it might prove difficult, and an 8GB kit is pricey.

    I tried to choose memory that would be as compatible as possible, and did a search for 4x2GB DDR 800 1.8V. I came up with this ebay link
    http://www.ebay.com/itm/New-8GB-4x2GB-PC2-6400-DDR2-800-240Pin-NON-ECC-DIMM-Desktop-Memory-8GB-Low-/271035655886#vi-content

    And this from Amazon
    http://www.amazon.com/4x2GB-DDR2-800-PC2-6400-Unbuffered-Memory/dp/B00A6UHZE8

    There is probably more.
