    Maybe interesting would be for notebooks!
    If my notebook only has 2 slots, and I have 2GB stick installed, and wished
    to increase RAM should I install 1 stick of 1GB, or 1 stick of 2GB?
    If I would install 1GB, I'll have more then enough RAM, but the question
    would be, would it still be Dual channel compatible or something?

    If I'd install a 2GB stick, would my notebook use considerably more energy
    then using only a 1 Gb stick?

    I have experimented with my 2x1GB/2x512MB DDR PC5300 SODIMM Memory sticks,
    and the benchmarks told me that my system was faster using 1x1GB then 2x512MB.
    Also my system was faster using 1x2GB instead of 2X1024MB.
    Now I want to know if it'll be faster using 1X2GB, or 2X2GB.
    Ofcourse the LARGE Memory benchmark tests show that 4GB will be better then 2.
    But in many cases the LARGE benchmark tests are not-real life, unless you
    do video/photo editing, or play lots of games on your laptop.

    That's not the case with me, I just want the smaller applications to run
    smoothly.
    By adding a 1x2GB RAM stick, I've been able to increase my VISTA experience
    from 3,0 to 3,1 (since my videocard uses 64MB shared memory), and yes I know,
    it's an 'older' laptop.

    So all of the tested memory was Kingston value memory; DDR, on a Sony Vaio
    notebook.

    I don't have any explenations as to why; but these where just but my
    observations.
    I would like to know what this 'Dual channel DDR'-theory is. (I'm just
    running a 32-bit processor, and am not thinking about upgrading it to a 64
    version).

  2. That doesn't matter much. Take it to 4GB if you like. Notebook ram is not
    the same as desktop ram where you have a pair of dual channel dimm slots.
    On a notebook don't worry about things like dual channel. After all, if you
    were running with one memory slot in use you could hardly have been in some
    sort of dual channel mode anyway. The power requirement will not be very
    much. Notebook ram is designed with that in mind.

    the 32bit versions of XP and Vista are limited to 32Bit address space, this
    has to include space for all hardware mapped into the address space as well,
    so you will never see your full 4Gb of memory (I see 3326MB on my machine).

    i was reading this thread looking for an answer to some thing else and RICK
    you might be able to help me.
    is there any way i can install 32 bit software onto 64 bit vista, does the
    32 bit control panel let you do this in any way, and im not sure if i saw a
    32 bit programe bit in vista somewhere.
    i am still a bit new to all this cpu stuff so if my question is a bit stupid
    i`m sorry.

    thanks scrummage.

    Hi,

    Most 32-bit software will install to a 64-bit system and run in 32-bit mode
    without issue. The problems occur when the software includes device drivers,
    such as the iTunes software, as these must be signed, compatible 64-bit
    drivers or the software, even if it can be installed, will not operate
    properly.

    There is now a specific 64-bit version of iTunes. You can download it from
    the Apple site if you are running Vista 64.

    modules. By no means is it a fully 64-bit program.

    I have only two DIMM slots with a 2GB stick in one on my desktop running vista 32bit, should I install an identical 2GB to activate dual channel, making it 4GB, or should I just get another 1GB to stay within the 32bit OS limitations of 3GB?
    each slot can operate with a maximum of 4GB RAM sticks a total of 8GB.
    And if I do go to 4GB, can't Vista allocate the video memory from the excess of the 3GB limitation, and can't I use the extra as well as a RAMDISK?

  9. The limitation for a 32bit OS is 4GB, not 3GB. It is a simple mathematical function of 32^2. However, you get to use less than 4GB due to memory reserved by the computer's BIOS for hardware needs. It is common to see between 2.7 and 3.3GB even when 4GB is installed. This in not a problem with Windows. It is your hardware and the BIOS the manufacturer put in your computer. However, what you cannot use the system can so you are not really out anything.

    Dual Channel is slightly faster than single channel so go ahead and install the matched 2GB stick. As I indicated above, you will get the advantage of 4GB even though the memory available to your programs is less than 4GB.

    Vista does not allocate any memory for video. That is done by your BIOS. If you have a shared-memory system then you can adjust the amount of ram for video in the BIOS. If you have a standard video card then the BIOS will not have an option for adjusting the video ram.

    You can already use a Ramdisk, albeit a very small one. You would be able to use a larger one with 4GB.

    I would not consider going only to 3GB.

  10. You say "only two," but depending on what apps you run, that may be
    enough for you, and any more may do next to nothing in your case.


    That may give you some small improvement in performance, but not
    necessarily a lot.



    There is no 3GB limitation. How much you can access varies, depending
    on your hardware (although it's usually *around* 3GB). Here's the
    scoop on the subject:

    All 32-bit client versions of Windows (not just Vista/XP/7) have a 4GB
    address space (64-bit versions can use much more). That's the
    theoretical upper limit beyond which you can not go.

    But you can't use the entire 4GB of address space. Even though you
    have a 4GB address space, you can only use *around* 3.1GB of RAM.
    That's because some of that space is used by hardware and is not
    available to the operating system and applications. The amount you can
    use varies, depending on what hardware you have installed, but can
    range from as little as 2GB to as much as 3.5GB. It's usually around
    3.1GB.

    Note that the hardware is using the address *space*, not the actual
    RAM itself. If you have a greater amount of RAM, the rest of the RAM
    goes unused because there is no address space to map it to.



    No.

    The best answer is to install a second IDENTICAL 2GB stick.
    Given that this is a laptop, it's likely that the Video system uses system
    RAM, so the extra RAM should not be wasted.
