Cool n´quiet in Windows 7 64 ?

    Hi,

    I´ve just upgraded to W7 64,  from WinXP SP3,  and was surprised that Cool n´quiet doesn´t work  at all (as opposed to WinXP 32).  AMD claims that w7 has native support to it:  you have only to enable it in bios, and set Power saver, in Power Options,  but no sucess  here.  Seems to me, it´s a driver issue, although I have tried every one in AMD support page.  

    So,  any help will be well come.

    My setup:  Athlon 64 3200+ (Venice)/ Asus A8V-X (last bios update)/ 2 GB DDR400/ Radeon HD 3850 agp

    What was your hypothesis? Did you believe that you could reduce the CPU load by upgrading your OS from Windows XP to Windows 7?

    I supose there´s some "fail" in W7 power management that prevents it from recognizing C n´Q  in the Athlon 64 3200+.

    (Thanks for answering !)

    At first I thought you were some nut job. But, I searched for cool 'n quiet, and to my surprise, this is actually sanctioned technology.  May wonders never cease!

    How are you checking your power usage, with a kill-a-watt or just by the sound of the fans?

    Can you still achieve Cool n Quiet without loading the windows? I mean, purely BIOS based? I remember I can set it on BIOS to stop insane fan usage when loading windows.

    Leaving WM on 5/2018 if no apps, no dedicated billboards where I drive, no Store name.

    Windows 7 does have native support for it. If you've only just done the install though, post install tasks like indexing may well be keeping the CPU busy enough to engage the fans.

    My desktop has an Athlon II x2 560 processor with Windows 7 64bit OS, cool 'n' quite works fine.

    I used the cpu-z utility to observe processor frequency changes.

    I´m using SpeedFan, that monitors fan speed, temps, and core voltages.  CnQ can  lower cvolt from 1,47v to 1,17v, almost 40% power reduction, reducing fan speeds,  EMI, and processor speeds.

    Yes, CnQ is enabled in setup,  but AFAIK it only works in windows.

    CnQ is supposed to work whenever  the processor is idle. (maybe I didn´t understand your post)

    "My desktop has an Athlon II x2 560 processor with Windows 7 64bit OS, cool 'n' quite works fine. I used the cpu-z utility" Maybe this is an specific issue of W7, or the bios, or CnQ.

    Try using CPU-Z to monitor instead of SpeedFan. I've always had problems with SpeedFan overriding settings, even when I was just using it for monitoring purposes. And if you did just install Windows 7, it takes a few days to build up the indexes and such, so your CPU won't be idle.

    I´ve installed Cpu-Z,  but it just indorses SpeedFan...

    To whom may concern,  Event Log/ Kernel-Processor-Power tracks the error with CnQ:

    In other words, you need to flash your BIOS (and/or possibly other firmware like the graphics card BIOS) if you want full C&Q functionality.

    I´ve made a ticket in the Asus support site,  with the error description.  The last bios release of my mobo is from 2006.  I don´t believe they will release antother one,  however...
