Hi,

I am having a problem with the Cool`n'Quiet function on this CPU! It is not
working when the laptop is running on battery but it works fine when running
on AC! On battery, the processor speed is always stuck on 1000 MHz according
to PowerNow! Dashboard Demo no matter what power scheme I am using, home,
portable, always on! On Ac it does function, when I am using the always on
scheme, the speed is always 2000 MHz and on portable the speed cycles
between 1000 and 2000 MHZ as it should! Is this by design, is the speed
supposed to stay on 1000MHz on battery? I hope not and I hope that you can
help me fix it! There is no way for me to play my game on battery, it is not
fast enough!

I called HP support twice about it and they are clueless, they have no idea
what the [content edited] I am talking about. They finally said that it is
working as it should but I don't think so! I bought a 2 GHz laptop and I'd
like to use the 2 GHz even on battery!

I downloaded the new driver, ruamdcpu.exe, it uninstalls my current driver
which is 1.2.2.0 then after reboot it uses windows driver and I had to run
the .exe again to install the new driver properly but the problem is it
still shows 1.2.2.0 under hardware profile! I guess there isn't a 1.2.2.2
but on AMD web site it states there is a new 1.2.2.2 driver!

Please advise and TIA.

In addition to the Cool n' Quiet driver, you must have the latest
motherboard chipset driver, and your power scheme *must* be set to "Minimal
Power Management". Make sure that Cool n' Quiet is enabled in your BIOS.

Most laptop manufacturers lock the processor at it's lowest speed when on
battery to conserve battery life. You used to be able to install the Win2k
PowerNow! (PowerNow! is the name used for cool 'n' quiet on mobile
processors) drivers in compatibility mode and make the CPU throttle when on
battery. That trick stopped working when done post-SP2 install. There is a
simple, free utility out ther eyou can se to fix the "problem" though.
Download RMClock and install it. It actually throttles much better than the
default throttling in XP anyway. It has many more steps, including half
multipliers if you enable it, and the threshold of throttle can be changed.

Thanks Bobby, I am assuming that I do, it is a brand new laptop and HP said
that everything looks good! I did try all the power schemes, the switching
works fine when running on AC but it gets stuck at half speed once switched
to battery no matter what!

Thanks for your help!



Funny you mentioned that, I got this utility today off the AMD web site!
Someone posted the link for it in the support forums. Surprisingly, it still
works; you just have to change the compatibility of the .exe file. I just
installed it and it added the PowerNow tab to WinXP power management. That
actually did the trick, once I enabled "dynamic switching" for battery it
stated throttling up and down accordingly. I chickened out though and
uninstalled it because I was afraid that it would damage my hardware! I was
not sure if PowerNow technology is compatible with the new cool 'n' quiet?
But if you say it is the same thing then I might just reinstall it and stick
with it, seems to do what I want done!



I have a question about the RMClock thing, is this safe to use? I am not
really comfortable messing with the CPU like you guys! Am I going to damage
something if I use the wrong multiplier or voltage and something else?
Again, thanks.
