    Hi all,

    I intend to upgrade memory from 2 GB to 4 GB for my Dell 6400 (1505)

    [​IMG] [​IMG]

    From Dell web page, maximum memory is 2 GB Dell specification but it seems that chipset i945PM can upgrade to 4 GB RAM.

    I am using RAM with cas latency 4.
    [​IMG] [​IMG]

    I have 2 options:

    G.SKILL 200-Pin DDR2 SO-DIMM DDR2 667 (PC2 5300) Cas latency 4

    G.SKILL 200-Pin DDR2 SO-DIMM DDR2 667 (PC2 5300) Cas latency 5

    but I don't know if I should buy RAM with cas latency 4 or 5 because G.SKILL manufacturer said that cas latency 4 isn't compatible with Dell 6400 HERE

    Please help me to answer if I can upgrade RAM to 4 GB and which RAM I should choose.

    Thank you so much

    i945 can hold 4 , but you'll only see like 3.2GB or something like that, because the 945's memory controller is 32bit. But you won't see a difference performance wise in either of those. I'd say just go with the one they said is compatable, just to skip some possible headaches.

    I open multi-task (Photoshop, Adobe Illustrator, Corel, etc) and my RAM usage is about 1 GB.

    In this case, should I need to upgrade from 2 GB to 4 GB?
    Thanks

    Did you just open the programs, or did you also open up files in the programs? Memory usage of those programs will rise as you actually work on things, since the files you're working on will also be loaded into memory and occupy space. At that point, it really depends on what size files you need to work on, and how much space those files will occupy as you work on them.

    When you have 4GB and you go to that same screen under the same circumstances it will show 2GB being used due to what I've *heard* is the way the OS handles the RAM.
