Speed problem with Intel Q6600 (Quad Core) and Ultimate 64-Bit

    I've been playing around with both the 32 and 64 Bit versions of Vista
    Ultimate on my new PC. The system specs are as follows;

    CPU: Intel Q6600 (Quad Core 2.4)
    MB: Intel DG965WH
    RAM: 4Gb (1Gb Transcend PC 800MHz x 4)
    Video: PNY 8800GTS

    In Vista 32-Bit, System runs well (Good CPU Utilization) but will not see
    all 4Gb RAM (3.2+GB Seen), system seems to be using a fair amount of RAM.
    Windows Experience score Rates the CPU at 5.9

    In Vista 64-Bit Systetm runs significantly slower than the 32-Bit version.
    CPU Utilization near 50% with system at idle for all four cores. Running
    simple software pegs all four cores at 100%. System sees all four Gb and RAM
    utilization is better than in the 32-Bit. Windows Experience Score has
    dropped the CPU to 4.6.

    Two other IT people at work with similar system specs have the same problem
    in 64-Bit Vista.

    Anyone getting good results running 64-Bit Vista on an Intel Quad-core?

    FIRST you need to learn to ignore the ram usage in Vista. Is is
    different than any OS before it. The more free ram you have means that
    Vista is not doing its job correctly. Ram is MUCH faster than
    harddrive speeds, therefore Vista is making use of the fast stuff and
    leaving the slower drives for XP.
    Second 32 bit systems have trouble with more than 3 gig of ram, just
    the way it is. Same system, 32 bit versus 64 bit, 32 bit has issues.

    Yes, but the 64-bit is so slow, that I can't even use Windows Explorer
    effectivly. 32-Bit works like it should.

    Also, why would my "Winodws Experience score" drop from 5.9 to 4.6 when
    switching from 32 to 64-Bit.

    Update to problem.

    While searching the internet, I found that this is a common problem with the
    Q6600 processor and more than 4gb of RAM. I removed two sticks of RAM and
    the speed improved (Even the Windows Experience CPU score was back up to
    5.9). I then added two additional 512 Sticks to make a total of 3Gb and fill
    all four RAM slots. System is still working like it should.

    So, it looks like Vista-64 Ultiimate has problems on computers with the
    Q6600 and 4GB of RAM.

    Well, I don't think it's due to your processor, however I do think it is
    either the board or vista. I as well have an intel dg965wh board with
    4GB of OCZ DDR2 800MHZ RAM. Running in 32bit vista Business Edition, It
    was perfect, though it only registered 3.2GB of RAM due to it being a
    32bit OS. I Loaded in a 64bit version and my CPU usage went off the
    charts, until I took out 2GB of RAM and since then it's been working

    I found other forums where people had the same problems with the Q6600, 4GB
    RAM and most had the nVidia 8800 GTS/GTX. It was happening with Asus, MSI
    and Intel boards. For some, downgrading the Bios a few versions to where the
    user had more control over the "memory hole" area for the video card
    corrected the problem. I will update the post with more URLs to the other
    forums when I get back to work (I placed them in my favorites at the office)

    I just built a system with a Q6600. I've got an Asus P5W DH Deluxe
    board and 4 GB of RAM. I'm not having any speed issues so far. The CPU
    is scoring 5.9 - and the RAM 5.5.

    The system is still initializing the Raid volumes that I built with the
    ICH7 Southbridge (having a Raid 5 volume and a Raid 1 volume on a
    desktop is going to be nice).

    The one catch I had when I started out was that the motherboard only
    registered 3.2 GB of RAM as available until I went in and changed an
    option to allow a 64 bit OS to see the entire RAM amount. That might be
    a spot to look for in your BIOS if you're having issues with speed and 4
    GB of RAM.

    Alright, so on the Intel DG965WH boards, to run 64bit OS and have more
    than 3GB without it slowing your system down you must downgrade to the
    bios revision 1669...

    Hi Drew:

    Thanks for your message.It's very helpful.

    I still have some questions. Maybe you can help me again.

    Does Vista recognize all 4 Gb memory?

    Does it work with photoshop cs3, coreldraw x4, finale, adobe auditio
    cs3, macromedia suite, and software like this?

    I know that Vista 64 will recognize all that memory and more...Your
    motherboard supports 8 gigs of memory so yes you are good there...I would
    assume it will work with all those programs as well but to be certain I
    would definitely check there respective websites.. Also possible peruse
    there forums for any possible bugs that there might be and ways you can get
    around any you might have... Sorry I was probably not all the help you
    need.. I wish you best of luck .. Enjoy that system as I have greatly
    enjoyed mine !!

    earlier, is your installer from MS or a downloaded copy

    2GB of ram is fine for x64 though the chief reason many use for installing
    it is to use more than 4GB. How much you should have depends largely on your
    use of the system. Gamers frequently find 4GB to be a sweet spot, and users
    of autocad and video editing software can often take advantage of more. Keep
    in mind though that memory at addresses above the 4GB mark cannot be used by
    32 bit applications, so unless yours are designed to take advantage of x64
    there's not much point to installing more than that amount.

    That said, wait until after you install x64 to add the additional memory
    (and it's a clean install, there is no upgrade path from 32 to 64 bit). The
    reason being that there is a timing issue when all 4 ram slots are in use
    during an x64 setup (it's not the amount of ram, but rather the number of
    installed sticks that is the problem). Once installed, the timing is no
    longer a problem.

    Ram is rarely high and cpu's rarely exceed 50% utilization while cor
