Cool n quiet with vista?

AMD Cool n Quiet doesn't seem to work on vista because vista supposedly has built in control. However, when I go to use this there are no processor options that show up. Do I have to enable cool n quiet in the bios?


Also if my computer is in sleep and/or hibernate will it still be able to record scdedueled recordings? Right now it is running all day and I would like if it could sleep then wake up to record.
 
It's in the power options, make a custom profile and Vista will automatically throttle the CPU multipliers when not in use.
 
I tried that, the options should be right under pci express but there is nothing there. That is why i am confused.


I am also having problems getting my computer to sleep.
 
to do Cool n Quiet, am i supposed to set "PCI Express" -> "Link State Power Management" -> Setting: Maximum power savings? (attempt to use the L1 state when the link is idle)
 
You're better off using RMClock for throttling your CPU; doesn't matter if you're running an AMD or Intel setup.

RMClock will throttle your CPU up/down based on load, but it offers several customizations like the ability to individually choose all frequency states, and the ability to adjust VCore for your CPU at each frequency state. I've been able to safely undervolt both AMD and Intel CPUs ~0.1v at every frequency state.

This program works great for most modern laptops and desktops.

Vista's system has been seamless so far, but I'm interested to see what additional savings I could get with RMClock. I'll hook up the power meter tonight and see what I can get out of it. Do you just use the 'Performance on Demand' profile?

Yes. The power savings depend a lot on your CPU and your chipset (how much it will let you undervolt).

I have a laptop with a Pentium M 733 ULV CPU in it, which has a TDP of 3W at idle. With RMClock, I dropped the TDP range down to an estimated 1.5W at idle by lowering the VCore.
 
I tried it with my E6600 at home and I didn't see any difference, 110 watts at the wall no matter what. Oddly the Vista throttle didn't seem to do anything either, although it shows less multipliers in CPU-Z when it's throttled back. Either the E6600 has some internal system, or I've messed something up.

Vista PPM on - 110
Vista PPM off - 110
Vista & RMclock - 110

I'm taking my meter to work tomorrow to test it there. It's an older Intel dual core with far less options in RMclock.
 
3.6 Prescott Dual is a solid 100 watts at the wall, no matter RMclock status. Speed Step is enabled in BIOS and all settings are blue in RMclock. Odd.
