SD Card using ReadyBoost increases CPU to 100%

    I have two IBM ThinkPads, X41 tablet and Z60m running Windows Vista
    Business installed in exactly the same procedure. Both have SD card
    slots so I bought 2 SanDisk Extreme III 2.0GB SD cards setup for full
    use on ReadyBoost as I wouldn't use these card slots for anything
    else.

    The X41 with the SD card works perfectly. BUT when I enable ReadyBoost
    in the Z60m, the CPU starts running at 100% and the HDD light starts
    to flash and the whole system becomes laggy.

    If I disable ReadyBoost, the CPU returns to normal. I have changed
    cards around and its not the cards. I have formatted both cards, no
    change. I have reinstalled latest driver for SD Card Reader from IBM
    and no change.

    The issue is purely a ReadyBoost one...anyone had the same problem or
    might know where I could have gone wrong?

    Yea, you're messing with stuff that's likely to give you little to no
    added benefit...in a best case scenario.

    You're better off just putting more RAM into your machine and calling it
    a day.

    Well thats not actually true. The X41 has 1.5Ghz Centrino with 1.5GB
    RAM and when the SD card is added it makes a massive difference.

    The Z60m has the maximum 2GB RAM combination possible, and any extra
    help in a slot never to be used cant be bad.

    Yea, I can see the massive difference it is making by your original post.
    Your entire system becomes laggy, I admit, that's quite a massive
    difference.
    Actually yes it *can* be bad.

    Flash memory is by magnitudes slower than RAM. Adding it to a system as a
    substitute for RAM helps with systems around 512 megs of RAM or so that'd
    otherwise be constantly writing to the HDD instead. And even there,
    improvements can't really be guaranteed.

    If you already have 1.5 gigs of RAM, you're looking at next to nothing to
    gain by adding Flash memory.

    Even on systems where ready boost has been reported to actually give some
    improvements, any improvements started to disappear at the 1 gig mark on
    any benchmarks I've seen so far.

    Thanks for your more detailed reply, your first post seemed very
    dismissive of the problem by just saying add more RAM as that isnt the
    problem in case.

    With the X41 (slower processor and less RAM than the Z60m), the SD
    card makes a visible improvement.

    The Z60m has massive spike in CPU when ReadyBoost is enabled on the SD
    card...it has a 2Ghz processor, 2GB of RAM and a very good graphics
    card (by laptop standards) so why should the CPU overload of 80-100%
    when the SD card is added even f the system is capable of running
    Vista without the SD card.

    The validity of the SD card is debatable, I just want to know why
    ReadyBoost would cause a CPU overload?

    Thanks.

    Have you been taking lessons in reading from alias?
    The OP said quite clearly that it works perfectly in the X41 but not in the
    other.

    * Stephan Rose:
    Stephan,

    You are correct. I have three machines currently running Vista,
    all three have 2GB of RAM, and the only time I have ever noticed a
    *little* bit of help from ReadyBoost is when I am using a virtual machine.

    ReadyBoost is one of the most over-hyped features of Vista, by far.

    Yes and I am responding in regards to the one that doesn't work.

    Now, what exactly did you contribute with your post?

    I'm not dismissive of the problem, I'm just dismissive of the incorrect
    solution.
    It shouldn't, I'll agree on that much. Probably a bug somewhere in
    Vista's 50 million lines of code.

    That said, any kind of paging is bad. Period. I don't care if it's paging
    to a hard drive or to a flash drive. It's bad. Everytime a page miss
    occurs, it triggers a page fault interrupt, then the correct page has to
    be loaded into memory from whatever slow media it is stored on, and if
    insufficient memory is available for that, another page not currently in
    use has to be stored to whatever slow media is available.

    All around, it's a bad thing to be happening.

    Computers that are really far below spec for Vista can benefit a little
    from paging to a flash drive instead of a hard drive, under the condition
    that said flash drive actually has sufficient bandwidth. Not all are
    created equally.

    But even if such a computer sees benefits from the flash drive, the
    benefits said computer would see from additional RAM are by magnitudes
    greater. So no matter which way you slice it or dice it, RAM is always
    better than flash.

    That's why I roll my eyes at Readyboost and it's hype and dismiss it as
    one of the most useless things to ever come out of Redmond. Ultimately,
    the best suggestion I can make to you is to stop mucking around with the
    ready boost, throw some more RAM into the machine and be happy with the
    far greater benefits you'll get as a result.

    Well you appear to have got the idea that it has made his x41 slow and laggy
    which it hasn't.
    Its his other one of the two that has the problem.
    So my post should have cleared that up for you.. but maybe it didn't.
    Maybe you are just so keen to get in a bad word you didn't read it properly?

    Where did I mention the model number x41? Where did I say that?

    And no, I don't need you to clear anything up for me.

    Well its conventional to be commenting on the quote above your reply when
    quoting in-line.
    I suppose you may choose to be replying to something else if you want to
    confuse people.
    That OK but please try to clear things up for the rest of us not blessed
    with sixth sense then.

    FWIW I have 2GB of ram and I see a slight improvement in responsiveness
    with a 2GB SD card. Granted it's not like "night and day" but it's
    better than not using it. The laptop it's in has a card reader activity
    light, and I see it flicker often, so it's doing its thing. ONLY
    because I got the card on sale ($19.99) do I feel it was worth the
    effort. I'd feel foolish had I spent north of $40 for the card. YMMV.

    I think I need to put a few things straight...

    The X41 (1.5GHz 1.5GB RAM) improves with ReadyBoost.

    The Z60m (2.00Ghz and 2GB RAM) gets the CPU overload with ReadyBoost.

    BOTH machines have the maximum RAM configuration so adding more RAM is
    out of the question. Both machines respond well without the SD cards,
    but after the visible improvement in the X41 I did the same for the
    Z60m.

    Whether paging is bad or not is irrelevant, I just want to know why
    the Z60m gets CPU spikes when ReadyBoost is enabled...??? As
    ReadyBoost should surely cause the opposite!!

    Do they both use the same SD card reader hardware and drivers?

    Different SD card readers, but I have installed the latest drivers for
    both direct from the IBM website (both Vista drivers).

    When ReadyBoost is NOT enabled on the Z60m, the SD card works as it
    should. The issue I am having only occurs WHEN ReadyBoost is enabled
    on the SD card.

    Have you tried disabling ReadyBoost on that card while in that laptop,
    reformatting the card then enabling ReadyBoost?
    Also be sure and go into device manager and under Disk drives enable in
    properties on the card, "optimize for performance".

    It sounds like its a problem with particular drivers and/or hardware to me.
    People report it working with SD cards on some machine but not on others..
    Vista is common but the drivers and hardware are not.
    Someone needs to compile a list of not working hardware and drivers to see
    if there is a common problem.

    Looks like windows updates, when you have installed make it so crapp
