Low memory performance rating

    Any chance you have 4x 512 sticks in an nforce 4 motherboard? I do and by
    default DDR400 memory runs at DDR333 speeds and I had to manually set them
    to DDR400 speeds and timings.

    Have 2 G of matched Kingston PC3200 in a dual channel mode.
    Why would my memory rating only be 3.7.
    I see all comparable ones up in the high 4's.

    Colin,
    They were 512's and it is a nforce 4. Now their 1 G each, DDR400 (PC3200).
    Do I have to make a change in the BIOS settings, like the voltage?
    And thanks for a quick reply.

    Worth a shot,

    At the post screen on boot you should see a line about the memory, it should
    say DDR400, but might say DDR333.

    It's worth hitting delete during POST and having a look inside your BIOS, it
    may also be worth seeing if your mobo manufacturer has a new bios released.

    There is literally a whole bunch of reasons that this can happen, if you
    have an Athlon64 before the Venice core was released it could be it, as AMD
    updated the memory controller, it could be the bios as boards have been
    updated to fix memory problems on it. The memory might even be faulty
    memory.

    I have 4 x 512 sticks of Kingston ValueRam DDR400 memory and have to reset
    the timings and speed in the bios otherwise they read as DDR333 and I get a
    WEI of 4.9 for it afterwards.

    I get 5.9 from 2GB's of 800mhz DDR2 memory. There are lots of different
    speeds in memory so the higher the speed the better the performance will be.

    True but, I'm stuck in DDR400 mode with the same brand name of memory as the
    top poster, it more than likely his is underperforming. Without the benefit
    of product numbers I can't be more accurate but it more of a like for like
    comparison than [email protected] mhz.

    I'm using the new Kingston HyperX KHX3200K2/2G
    I didn't have dual channel as I thought, moved to DIMM1 and 2.
    Also moved the memory voltage from 2.55 to 2.65 which the Kingston site says
    is allowable.
    Prior to all of this, various benchmarks including SIS Sandra Pro told me
    that the mem speed was decent, not outstanding.
    The memory portion of the "PC Pitstop" test rated me at 78% of comparable
    units.

    And a 3.7 from Vista.

    Since the change to the proper dual channel config and increasing the
    voltage, sandra gives me a great benchmark, PC Pitstop says I'm at 102% in
    memory speed comparison and

    Vista still says I'm a 3.7.

    Overall performance of the machine, sort of built for Vista, is outstanding
    with both XP and Vista.
    The rating, however, tells me there's still something wrong, or buggy, since
    others with the same type rigs are getting high 4's.
    Maybe I should just forget it but I'm not a quitter.
    And thanks, folks, for jumping in.

    I have 1.5GB of DDR400 PC3200 RAM, Corsair ValueSelect, running in Single
    Channel mode. Vista's rating gives it a 4.5

    That *is* strange. I have 4 GB dual channel PC2100 and get a score of 4.2 in Vista
    RTM.

    Just by a quick assessment here, but, did you re-rate your system in Vista
    after moving to dual channel?

  12. PC3200 is DDR RAM

    Most new computers are delivered with DDR2 RAM which is quite a bit faster
    and will give you a higher score.

    Sounds good, I'm sure if you trawl the the internet, someone will have the
    same memory and motherboard and the same issues. If other benchmarks are
    giving you good readings, I'd not worry about Vista. The most important
    thing is if you notice the good/bad performance, benchmark are only a guide.

    Bear in mind that if you experience any stability issues, it could be the
    memory causing it as I suppose technically you are overclocking it and Vista
    seems more sensitive to memory than XP.

    Mike, Yes I did re-rate.

    Richard, aware that DDR2 will give you higher score.
    My point in discussing this is that similar or systems with less memory will
    receive a higher memory performance rating. There are some on this post,
    Jane, for example, with 1.5G of DDR PC3200, single channel with a score of
    4.5.
    Mine is 2 G DDR 3200, dual channel with a 3.7.
    Based on the comments here and elsewhere, I don't think I'm going to give
    much weight to the performance ratings even though MS has given it a lot of
    buzz.
    Thanks to all, especially cheddarhead who really showed his expertise in
    Vista.

  15. I am sure that the "clock" speed of the RAM enters into the picture. Not all
    PC3200 RAM is created equal. (-:

  16. Well, I know that if I go with the default ratings provided by SPD for my
    Corsair RAM (clock 2.5) - I get one reading.

    If I then manually change to the maximum speed timings (clock 2.0) I get
    another reading.

    As I said, it could just be in your timings. Until you have tried
    everything, you just don't know - do you?

    And again, all PC3200 RAM is not created equal.

  17. That is exactly the RAM I am using (2 gig worth).

    It may be a M/B anomaly. Hint: they're not created equal either.

    I go from 3.7 to 3.9 when I run at clock 2 settings.
