HP Intel Core 2 Duo Notebook: Vista Ultimate 64 or XP Pro 32...?

    I have a relatively new HP Core 2 Duo laptop that shipped with Vista
    Ultimate 64. It's in dire need of a reformat and reinstall of the OS --
    checked with HP and there are no Vista SP1-Integrated restore discs
    available so my options are to restore and then apply SP1, or, just go with
    XP Pro 32.

    The 64-bit Core 2 Duo with Vista has been OK, but more sluggish than I was
    expecting -- would I experience even slower performance by going to XP Pro
    32? I don't know what, if any, advantages I'd be giving up by not going
    with a 64-bit OS. While my laptop shipped with Vista-64; XP drivers are
    available from the HP support site.

    After a year of sluggishness with Vista, I'm willing to give up the slick
    interface for zippier performance. If anyone has the time to explain (or
    provide a link to) info about what'd I'd be giving up by using a 32-bit OS
    with a processor capable of utilizing a 64-bit one. Thanks!

  2. I believe XP would serve you well as long as there isn't anything by way of
    software that you are running that need more than 2GB memory or needs to be

    On the other hand, making the decision that the machine needs to be
    re-formated and the system re-installed tells me you are in the process of
    learning and that responding to your own 'first impression' might be a good
    thing to do. Sure, I've heard that Vista is sluggish in comparison, but I
    doubt that a well configured system would benefit enough from a down-grade
    except, perhaps, from the point of view that you might feel more confident
    handling the configuration of XP better than you would Vista?

    I would re-install your Vista now in the firm confidence that if you cannot
    bring it up to 'par' you still have XP to fall back to. Both scenarios are
    basically 'sound'.

    Any info that's a little more specific? Know of any ways a 64-bit OS would
    utilize a Core 2 Duo that a 32-bit one wouldn't? I have no issues or
    questions regarding configuration of either OS.
    Ben, May 16, 2008
  4. No, not really - with one possible exception which might be 'Hardware
    Virtualisation Support' if you are running VM's.

    The thing with a 64bit OS is that it 'may be' faster only if a 32bit system
    is bogged down running the same jobs on the same machinery - if the 32bit
    system can expedite your jobs without delays you wouldn't expect to see any
    difference at all, the rest would be configuration issues, I honestly think.

    I think there are 2 key differences.
    First the amount of memory a 64 bit system can use, in a laptop you can
    ignore this for now since I doubt there is space for more than 4 GB RAM
    (of which 32 bit Windows will see around 3 to 3.5GB) in the laptop. (I use
    XP x64 to allow me to use the 8GB RAM in my desktop PC).
    Second would be if there was a specific 64 bit application that you need
    to use, at the moment 64 bit apps are about as rare as hen's teeth though.

    I would think there will be little speed difference between 32 bit/64 bit,
    XP may be a bit faster but now that Vista drivers are maturing it seems to
    be catching up.

    ow about shutting off the eye candy (Aero), run classic, and stick with
    the newer and better supported OS.
    PCMag's ExtremeTech just did a XP SP3 vs Vista SP1 compare running games
    and found little difference.

  8. The OS makes no difference with regards to virtualization. The hardware
    support is in the cpu, not the OS. VPC and VS will detect this and make it
    available to vms.

  9. You don't say how much memory you have. It matters a lot as does using a
    flash drive for superfetch if you have only 1GB or 2GB.
    Colin Barnhorst, May 17, 2008
  10. Ah - good, I did know about the CPU being the functional 'driving' mechanism
    and that BIOS support is needed as a trigger but couldn't quite remember if
    a 'modern' OS wouldn't be helpfull as well - any way, if you're doing
    serious VM computing you'd probably relish loads of memory and 64bits would
    fit in well?

  11. Oh yeah! Especially if you run more than one vm concurrently. I run a
    couple of Vista vms with 1 or 2GB of ram allocated and my 8GB Vista x64
    system handles it just fine. A 32bit host would hunker down something awful
    at that point.

    2 gb RAM -- the maximum for this particular model.
    Ben, May 17, 2008
  13. What is the model?

    I don't know of any Core 2 Duo systems using DDR rather than DDR2 though
    perhaps you have one. DDR has issues that make it essentially a 2GB memory
    model but you may be able to use more than 2GB if the system is using DDR2.

  15. That laptop does use ddr2 but according to HP and Crucial.com you are at the
    max as you indicated. I was hoping you could swap out the two 1GB modules
    for 2GB ones, but no go. I certainly would consider using a usb thumb drive
    to improve performance. One I use is: (Although I use the 8GB model)
    Mine has been great for readyboost for over a year.

    Readyboost is briefly explained at:

    Not sure how this is related to my original question, but thanks for your

  17. I was responding to the sluggishness you mentioned in the OP. Ram and
    caching are key to that so more ram and readyboost are things to look at.
    More ram turns out not to be an option but readyboost certainly is.

    I didn't ask about sluggishness, thanks though. What I was curious about
    was what I might be giving up by going to from Vista Ultimate 64 to XP Pro
    32, performance or feature wise. I have a feeling on this particular system
    things might be considerably faster, but thought someone might actually
    Ben, May 18, 2008
  19. You need to investigate things like your hard drive controller drivers and
    such. You are likely to see the same issues with either platform. I use
    Vista Ultimate x64 SP1, XP Pro x64 SP2, and XP Pro SP3 on the same dual-core
    box with 4GB of ram and all are very fast.

    btw, to quote from your OP, "The 64-bit Core 2 Duo with Vista has been OK,
    but more sluggish than I was
    expecting" but whatever.

    Thanks for you ideas. Sorry you misunderstood my statement as a question...
