    Hello guys,

    i have several Boards (originally Fujitsu Celsius V830 but these are the same as Gigabyte GA-2CEWH) i want to upgrade to the latest option (2x Opteron 290, 16GB of registered ECC RAM DDR-400).
    I have the problem that the Boards are running all the time with full Vcore Volts and full time with 2,8GHz at all cores.
    So PowerNow seems not to work.
    If i changed the CPUs to Opterons 285 (2x 2,6GHz) or 256 (1x 3GHz) and PowerNow is then working(but these CPUs are slower as the 290).
    So it is definitely the Board.

    I need help very urgent!
    Because i lost almost 1 CPU because of overheating. The CPUs are getting too hot if PowerNow is not working.

    I have already tried the latest Fujitsu Bios and the latest Gigabyte Bios. Both are not able to work with PowerNow with the 290.

    Fujitsu it is not willing to help. (they say the Board is too old and because of 1 men, even when i have several board, they do not correct those errors).
    Gigabyte has said PowerNow is only for Notebooks. So these "engineer" has no anticipation to their own products.
    I have to explain him that this feature is already supported in the older CPUs and that Gigabyte already has corrected Bios files with older versions with the words "Support 285 power now", but not for 290.

    Both supports are a mess!
    :mad:

    Would be helpful if you posted some BIOS links.

    This is an easy one.

    Most, if not all AMD socket 754/939/AM2 compatible boards required a BIOS update for Vista to properly support Cool'n Quiet / PowerNow!.

    Vista was released on Nov 30, 2006 and the last BIOS update for your board is dated 2006/08/22, so it surely does not have the fix included.

    Just to clarify, the BIOS patch also applies for later versions of Windows (7 and 8).

    To tqhoang:
    Latest Gigabyte-Bios-File: download.gigabyte.eu/FileList...cewhrh_f14.exe
    Latest Fujitsu-Bios-File: I can`t get a direct Link. You have to switch to "Support" and "Download Drivers" and take a "V830 Workstation" and download the file by click (Latest Ver. 1.09)

    To draken:
    PowerNow does not work in Windows XP and Windows7.
    When i place an Opteron 256 or 285 in it PowerNow works in Windows XP and Windows 7 without any more changes. So it is definitely a bios problem.

    @keys2004 - Until I have time to look at the BIOS, here's a utility that should work for you in the mean time. RMClock

    I have already tried with RMclock bevore.
    It does not work.
    I can`t say why but i think the bios blocks it.

    Ok, I'll try to make some time for you now. It's going to be a hard-coded hack, so definitely don't use this on a PC w/o the Opteron 290's. Also it will probably only work with Windows 7/Vista/Server2008[R2] since I don't know how Windows XP/Server2003 implement PowerNow.

    Can you provide the following:
    1. Download a Linux LiveCD and boot up with it. Then login and run "dmesg | grep -i powernow" and send me the output.
    2. Make sure you're running the Gigabyte F14 BIOS (USA, EU). Under Windows, install RW-Everything and generate a full ACPI report. Zip and attach it to your reply.
