Hi Jon, I understand and I certainly don't want you wasting your time doing that. I don't think its so essential to check the actual clock speed because the real point is if this saves any power or not. If its not too much trouble could you just try underclocking it in windows and then just reboot (without shutting off) into Linux and compare the power consumption then to your standard power consumption (without changing anything else)? If I recall correctly this can be found in /proc/battery/ or something like that. All this would involve is just you installing atitools for windows which I presume works (and its a .exe in any case so should be easy to try):
http://www.techpowerup.com/atitool/ If you see a difference than others like myself can try and work on gettings windows installed and playing with this a bit. If not then either (1) the underclocking does not significantly effect the power usage or (2) it just doesn't hold after a reboot. You can try to test the latter case by rebooting (again without powering off) into windows after Linux and seeing if it says the settings hold (though it may just set them in windows startup so this is not a clear indication). The one reason I have hope that this might work is that I think some OS X users use this to clock up their chips for OS X but I'm not sure of that. One final comment: if you really want to check whether the chip is being underclocked more concretely just use fgl_glxgears (or just glxgears) before and after underclocking in windows. I would think the output of these should differ significantly if you underclock the chip (otherwise why would people waste so much time overclocking). I really appreciate your checking this. thanks, Sheer On 6/11/07, Jon Grosshart <[EMAIL PROTECTED]> wrote: > > > On 6/11/07, Sven Anders <[EMAIL PROTECTED]> wrote: > > Jon Grosshart schrieb: > > > > > > > > > On 6/9/07, *Sheer El-Showk* <[EMAIL PROTECTED] > > > <mailto:[EMAIL PROTECTED]>> wrote: > > > > > > Hi All, > > > > > > This was already requested before but nobody responded so I'm trying > > > again.
